iv'e looked at the following code:

in another directory I have text files in /tmp/files/*; I think
the files over there grab the 10 files; *if* I stick the

putting these files together and grabbing the content of the

pretty sure I tried something like this about a week ago.
maybe last monday. it may have segv'd. but YES in cp_text.c
is ::

L[i++] = p;

here p is the string or stringgs *within* /tmp/file/text.N.txt;
I planned on passing L[] to what you have above: first text,
second text.
in my example text.1.txt files I have (e.g.) i am bringing this
laptop to the group so I can be more easily understood.
…
After this, instead of creating a string label1, you just need the
number 1, and can use this:
s = gtk_label_get_text(GTK_LABEL(label[1]));
where 1 can instead be a variable of int that holds 1:
int num = 1;
s = gtk_label_get_text(GTK_LABEL(label[num]));
many thanks indeed. I'm' going to save your mail and get a
hardcopy. tthen join the directories, c.

This definitely calls for an array:
GtkWidget *label[1000];
as you cannot reference to a variable with a constructed name (like $$a in
PHP). If your struct holds only pointers, though, you can also cast it to
an array:
((GtkWidget **)label_list)[99]
but I haven't tested it, and highly discourage it.
I will heed your advise! a workaround may be in three *.c
files. but first:: sleep.

*YES*. in another directory, three or four C files grab hold
of [[ Say ]] /tmp/files/text.3.txt {or} /tmp/files/text.NN.txt.
these TXT files contain what the speech-ompaired person has
typed. they are voiced by espeak and other speech binaries.
when I hit the up- or doen-arrow button I want SOmething to
appear on the window that has the arrow icons. when the
user hits Enter or mouse-clicks, that Something voices what
the users himself cannot.
In that case, I’d like to know
if you have a GtkApplication with GtkApplicationWindows, or “just” a
simple GtkWindow?
in my arrow.c, in main(), I have a
GtkWidget *window;
and after gtk_init() is:
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
.
.
.
so it is just a simple window.
For the former, I would go for actions and accels (see
gtk_application_set_accels_for_action() and friends), while the former
may require catching the ::key-press-event signal.
Best,

I'll google around and see what functions do what! iv'e seen

guys,

label with label1, label2, label3. in labelWidgets.h I've got
a *label[32], and use a global tt=0 that is inc in a for loop.
the gcc line builds ./leftJ after you unshar or simply run sh against
the sharball.
it doesn't segv or anything; but it only printfs the last line. WITH
complaiints. can any body help me here?
tia,

Looks like your attachment didn't make it. Can you post the code sample
online, or include the problematic part inline?
Marcus
hi marcus,
don't know what happened to the SHAR file. BUT: below is the
entire program--minus the labelWidgets.h header. the header file
just had the int tt.
as-is, this printfs the 700 by 900 window and the third label.
last night, localtime here in seattle, I send mail to two
chaps named chris, moller and vine. My *main* problem is that
I don't know how to add multiple labels to a single vbox.
Clue me in and givve me a place to stand, and I'll be able to

guys,
last time I encloused this leftJ* code, it output a 700 by 900
label with label1, label2, label3. in labelWidgets.h I've got
a *label[32], and use a global tt=0 that is inc in a for loop.
the gcc line builds ./leftJ after you unshar or simply run sh against
the sharball.
it doesn't segv or anything; but it only printfs the last line. WITH
complaiints. can any body help me here?
tia,

hi marcus,
don't know what happened to the SHAR file. BUT: below is the
entire program--minus the labelWidgets.h header. the header file
just had the int tt.
as-is, this printfs the 700 by 900 window and the third label.
last night, localtime here in seattle, I send mail to two
chaps named chris, moller and vine. My *main* problem is that
I don't know how to add multiple labels to a single vbox.
Clue me in and givve me a place to stand, and I'll be able to

gtk_widget_show (label[tt]);
...and pack the same widget (label[tt]) three times. GTK widgets can
only have one parent, adding them several times is incorrect. You need
to pack the first widget before setting the label[tt] to the new one.
Or more likely, you need to remove the loop and use 3 different
variables (or indexes), the loop seems to be misused. A loop runs the
*same* body several times, it doesn't magically make different
assignations to the same index work like if they were different ones.

Hi, Gary.
Maybe I'm not clear on what you want to accomplish. Are you wanting to have a
numbered list with padding? Screenshots/diagrams/mockups are definitely
welcome! :-D
How you're doing it seems fine to me. As long as it gets the job done you're
doing it right :-)
hi jordan,
damn, I wrote around 15 lines; it got lost... Anyway, I'm
inclosing a screenshot to demo that the 40 lines does do what I
want. the gotcha is that I'm pretty sure that the newest GTK
--3.0--was to NOT use how I had leftJ.c coded. it works the
way I want, tho. I do not know what you mean by padding;
it is or may be a fine point, but in time this stuff may give
me troubles. ---if you had the GTK 3 libraries installed
I do have the gcc compile and link line.
Other alternatives:
gtk_label_set_justify:
(https://developer.gnome.org/gtk3/unstable/GtkLabel.html#gtk-label-set-justify).
You can use this in addition to setting the widget padding.
can you point me to some example code? my leftJ.c was my
example [!]
ciao!

well, I've been at this for more than 9 hours. almost nonstop.
need the list's help.
while I can create several {N} labels, they print centered. how do I
get the labels to print from the left side of the window widget:
1. label1 text, blah**3.
2 label2 text: whatever
.
.
.
N. LabelN: text: more label strings
??
I have googled here and there. only one of my foobar.c files *seems*
to print from the left. (there is lots more to this test; getting the
list of labels or strings neatly printed is only the start.)
thanks,

thanks to you and tony newman, both. you included what I needed

so far I don't believe I've used gtk_set_justify; I appreciate
the tip. I'll google up the function for v 3.0 if it's still

properties.
These are preferred and the GtkMisc API, while not officially
deprecated,
is not recommended for use in new code[0].
Instead, you should be able to use:
gtk_widget_set_halign (label, GTK_ALIGN_START);
This should align whatever widget to the left of the available space for
the given widget (or to the right in RTL mode) - this API can also
be used
for any widget (it is not limited to GtkMisc derived widgets).
Cheers,
-Tristan

I'm going over the url you gave. I got up super early today for my
daughter who is going to study comp-sci this fall(!); so I really
do need more coffee or a *nap*. meanwhile, below is a testfile that
print N labels [[ here N == 3 ]]. Id send you the makefiles, but figure
you can mouse the gcc line. x2 is my lack of imagination.
at any rate, iv'e used the GTK__MISC string--macro? everything I'm coding
from now on is 3.0, so could you edit in the recommended way? you've got
halign; shouldn t I use the valign for mmy labels?
tx much,

wedged on enclosed with arrow code
well, after racking up somewhere in the neighborhood of 25 hours,
I'm stuck. the snippet below is from my *voice* code.
this program is in the Accessibility category and intended for the
users who are speech-impaired. the others can presumable speak and
hear normally.
every sentence/word/paragraph the impaired user types is stored in
/usr/share/voice. lets assume that the user had a laptop or tablet
and meets with his friends at a starbucks. before long, the textfiles
in /usr/share/voice {{*may*}} run into the scores. just in case
somebody asks the user to re-read or re-play something he said before
I want the user to be able to arrow-up or -down until he finds the
misunderstood text string.
right now, most of my program works. I use gvim with a simple set of
instructions; the program uses espeak and aplay to voice what is typed.
the problem is if there are more than a few strings to search. (each
filename opens a separate gvim. there are Next, Prev, Play, Quit
buttons on each gvim. searching thru many typewritten entries can get
messy.) Having a separate button without a gvim would be far easier.
/* from voice.c */
filename = g_build_filename (vhome, ifbuf, NULL);
infile = fopen (filename, r);
if (infile)
{
while (1)
{
nchars = fread (file_buff, 1, MAXCHAT, infile);
gtk_text_buffer_insert (buffer, iter, file_buff, nchars);
if (nchars MAXCHAT)
break;
}
fclose (infile);
}
else
{
g_print (\nERROR! could not open %s\n, filename);
}
hope this makes sense!

Guys,
I've been at this before noon; bushed. it compiles as-is with
GTK 2.0 but if you use 3.0 you need to comment out the lines around
+47.
since nobody out there in GTK land can help I am going back to the wayi
did most of the program. brrute force. I figure if I can cram the
up and down arrows into a small square then I will be able to expand the
TOPLEVEL window into something like 850 by 1500 and put my 30 to 50
text.[i].txt into the large rectange. take it from there.

how to choose oneOf[] an array of sentences?
=
Organization: Thought Unlimited. Public service Unix since 1986.
Of_Interest: With 27++ years of service to the Unix community.
Guys,
I'm having trouble getting my voice/speech program to use many
fewer instantiations of gvim. Having 2 or 3 copies of gvim
on-screen and fed thru a text-to-speech program like espeak
works fine.
{My speech is impaired, so I can and have used my program
when friends are over. It is *drastically* easier typing what I
want to say and having the computer echo my typewritten words than
waste minutes repeating myself until I can get my meaning across}
When if I have written
more than a few things and have them read to a friend, my display
gets crammed with gvim windows and text, it takes a lot of work
to keep the display readable.
It would be nice to capture *everything* I have written and
catenate and display them in just One gvim window so that if my
friends asks me to repeat/replay something I had said 10 minutes ago,
I wouldn't have to search back, back, back... .
[[ Closing a bunch if gvim windows until I've found what I had
said {or typed} several minutes before.]]
All the text files are stored in something like talk[N].txt. It
would be easy to find and bundle all the talk files in a bundle.
What I am having trouble with in Arrowing UP or DOWN to select
the desired text[K].txt file and have it read back to the person
who wants it repeated.
A fellow hacker thousands of clicks from where I live is a guru at
GTK+-3 and others have helped with my VBC program. The thing
is that he isn't entirely well either. I don't want to bother
anyone on this list or any other list or forum, but I can't
figure any other way of getting the job done.
One way of resolving the problem and that might be to
have something like this in one gvim::
===
My sentence or paragraph #1.
(Friend replies in speech.)
===
My sentence or paragraph #2.
(Friend replies verbally.)
My sentence or paragraph #15 or some N. What if or *when* my friend
claims to have forgotten what the computer had voiced and wants me
to replay it?
(Friend says, I don't remember what you were saying above on the
Faculty issue. Can you re-play that one part?)
==SO==, rather than retype what I remembered, and it could be a Yes or
No, or several sentences, I would have the program cat the text files
together to be read with eyes until the line or lines was found. Given
5 or 10 or 17 of my typings, how would a GTK3 hacker handle that:
selecting the right paragraphs to be repeated??
===
(Things can get into trouble if my friend asks me to go up to
{say} the 4th or 5th thing I have typed.)
Then in this gvim, I would press ESC and k or arrow up to the
misunderstood thing
in the list. I then hit enter/cr and the computer replays that
string or strings. This is where I get wedged.
Enough for now. I'd be much obliged for any help or feedback!
I'm going to append/attach a tarball of VBC and hope that somebody
who knows GTK3 and C can lend a helping hand and code.
--- A final note is that if this is the wrong list to ask this
question, or if anyone knows of other lists, to
please forward and cc: me. Thanks muchly!

Re: Can I install both GTK+2 and GTK+3?
Hello people,
Apologies if this is the wrong place to post my questions, but they
involve Ubuntu 13.04 and GTK+ as well. A few weeks ago I finished
porting my program for the speech-impaired to Ubuntu 12.04 LTS.
This is intended for the OLPC project and also runs on Fedora. Now
that my program runs on 12.04 I figure it should work on 13.04 LTS
without any mods.
In previous versions of Ubuntu, upgrading to the next LTS was
nothing more than a few mouse clicks but not now. Does anybody on
this gtk list who uses Ubuntu have any idea where I am messing
up? My other question involves porting my speech program to
laptop.org. Several other hackers have helped with the gtk code;
it is mostly 3.x. The nutshell is: should I just hand my
program to the sugar-devel folk and be willing to help with
what it needs {espeak, [g]vim, and whatever else} or what?
thanks for any help,
gary

hi;
yes, you most definitely can have gtk 2.x and gtk 3.x installed on the

what you cannot do is using gtk 2.x *and* gtk 3.x at the same time, in
the same process.
if you want to write your application to support both gtk 2.x and 3.x,
you can do that only by compiling once against gtk 2.x and again
against gtk 3.x — i.e. you will need two binaries.
targeting gtk 2.x is not a good idea, though, unless you're migrating
from 2.x to 3.x and you want to have a grace period for your users
to switch. gtk 3.x is already 2.5 years old, and will be 3 years old
when 3.10 is released this September.
ciao,

I'd like to be able to provide executables of my program for those with

compile. Unity seems delicate.

why the menu item Options/SetVoice won't exit
guys,
I'm clueless here. in my test voice.c, my widget based on
gespeaker works fine. I can change the voice from Male to Female,
change the pitch, Speed [WPM], Volume, etc. when I press the
Close button, voice.c fprintf's the changes to the setVoice
file, and closes nice and clean. when I insert this same code into
my voice-by-computer program, if the user opens Options/SetVoice
option to [[ let's say ]] change the gender from Male to Female,
then presses Close, the callback hangs.
Any ideas what I need to add to the Xoptions() function? it is
just a modified main() from voice.c:
int
Xoptions (int argc, char *argv[])
{
}
which has the dialog settings thus::
dialog = gtk_dialog_new_with_buttons (Voice Settings, GTK_WINDOW
(parent_window),
0,
GTK_STOCK_REVERT_TO_SAVED, //revert button which
GTK_RESPONSE_CANCEL,// returns a cancel response
GTK_STOCK_CLOSE,//close button which
GTK_RESPONSE_ACCEPT,// returns an accept response
NULL// mark the end of our buttons (we could
have more)
);
In the GtkItemsFactoryEntry menu_items[], icall Xoptions() like so:
{/Options/SetVoice, NULL, Xoptions, 0, NULL},
I do not understand why, in the test widget, yes, using main(),
it reads in the default settings and if the slider or the radio
buttons are changed, voice.c correctly rewrites the setVoice file.
but when I insert this code into my vouvebycomputer
gnu-accessibility program, things hang when I hit Close [[or
Revert
Anybody?
this is my program's last bug!

I cannot speak for your target audience but according to my experience (a) if people see a message box with a single button (probably with some visual clue that it has focus) they will just press Enter or Esc to make it go away, or (b) if people see a button they will always use the pointer to click on the button no matter what other, possibly much simpler, means may be available to activate it. This is a strict division with little between. There is no way to migrate people from (b) to (a), you can try for years with no effect.

vbc.tgz and dD.c == voptions.c enclosed.
Folks,
Attached in my vbc.tgz tarball; this is my working VBC
program. As-is, it works/installs only with /home/kline/.VBC;
then runs when you type make. make builds ./vbc.
Typing /home/kline/.VBC/vbc brings up the application.
Mouse-clicking on the second of the three lower buttons,
Run Text-To-Speech invokes gvim and espeak.
As-is, VBC would only with a male voice and the voice
options. Below, is the file I need help integration
into the top menu bar Options. This lets the speech-
impaired user the choice of changing gender and several
other espeak options. This is where I get into trouble.
Lines +433-437 or so below explain part of my problems.
I think I have taken this project about as far as I can
without some assistance. I need help from the
gnome-accessibility group as I work to modify and improve
this program for the disabled. Just that right *now* I'm
hoping this list can help me with the voice options code.
thanks much,

need help with final callback
Guys, I need your help with the last piece of my
voice-by-computer program. the appended section compiles to
the binary xD that lets the user choose the gender,
word-per-minute speed, delay-between-words, and pitch of th
e voice. Without this 'option' the user would type hello
and hit enter, a male voice would sound thru the speakers.
that's okay for *me*, nut probably not so if the user is a women
with impaired speech. in short, this callback option lets the
user select the gender and fine tune it.
I will let future developers deal with the text editor.
right now, vim is fine.
can anyone on this gtk list help me get this squared away?
thanks in advance,
gary kline

well be, but if so, i haven't figured it out!
this code will be on my options dropdown. please see

entirely raw and unpolished; there are no links besides my

the reason i am asking help is that my shoulder is giving

how to i set hscale wigdet to -- say -- 17?
thanks to a great amount of help from this list , my let the computer speak for the speech-impaired [AKA VBC] is making good progress. in fact, my Options pop-up from the menubar is almost ready for integration. but i still want it to look like the program 'gespeaker'---meaning that i want to set, say, Pitch to 17, Speed to 100, Speed in words/minute to a nice, slow 190. and the Delay in 10ths of a second between words to 2 or 3. i have experimented with people who suffer from a hearing loss and some whose native language is not English, c. so: better to default to a slower rate. i want to know how to have gtk draw that orange line from 0 to my default starting point. gespeaker presents a good example. i haven't found the magic google term[s] to find what gtk command i need. can any of you help? thanks in advance, gary -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Voice By Computer (for Universal Access): http:/www.thought.org/vbc The 8.57a release of Jottings: http://jottings.thought.org Twenty-five years of service to the Unix community. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

well, here's the story: i have a file that creates four hscale
widgets. 0 to 100. [optionally, four scrollbars that are in sync
with the hscale widgets. ok, the thing is: how do i capture the
user's choice from these horizontal bars and save thedir values to a
config file?
amybody? i'm wedged.
gary
Sorry for this:: but is there such a thing as a save
button option? lets say that the user choses 23 for his
pitch. could i have a save button confirm and write that
vsalue?? if so, how exactly?
scratching my head... -gk.
Hi,
gtk_adjustment_get_value () ?
Ciao,
zz
hmmm. the last two lines should grab the hscale value [i thought];
but nope::
void
scale_set_default_values (GtkScale *scale)
{
gtk_range_set_update_policy (GTK_RANGE (scale), GTK_UPDATE_CONTINUOUS);
gtk_scale_set_digits (scale, 0); // Zero digits after N.
gtk_scale_set_value_pos (scale, GTK_POS_TOP);
gtk_scale_set_draw_value (scale, TRUE);
double value = gtk_range_get_value(scale);
fprintf(stdout,hscale value: %g\n,value);
}
i'll play around with gtk_adjustment_get_value() and see
what it does. i'm trying to follow that gespeaker does;
but in C.
thanks,
gary

well, thanks to zz, i think i have something that actually
works
most or all of you know how, but for those wsho are new to gtk, i
will explain what i learned.
i have a value changed callback that prints the value every time
the horizontal slider is moved one increment.

cb_get_value (GtkAdjustment *adj)
{
double value;
/*
* get the value for each hscale
*/
value = gtk_adjustment_get_value(adj);

}
[ because i have at least four of these scales and the gender the
user wishes, i may not call this function until late in the
'Options' section. yet to be decided. ]
thanks to the whole list for everybody's help. i should be able to
finish the project from here on without any further questions.

It was something about overlay-scroll or whatever. need help tho
it took me the entire afternooon to get an idea of what those red
thin linnes a thumb bar were. i think it was only in ubuntu...
and i have fixed parts of it.
now i have two separate horizontal scrollbars. they range from 0 to
100 exactly what i want. and now, in place of that red line is a
regular groove with a tab inside that you slide to and fro.
my quandry is how to move the first grove up beneath the first
scollbar with a 0? do i need another box--a box4? i have tried a
number of things, but nothing works. can anybody help me?

whoa. i figured this would cause the whole things to segv, but commenting out these gtk_box_pack_start() calls got rid of the unnecessary horizontal brooves. //gtk_box_pack_start (GTK_BOX (box3), scrollbar7, TRUE, TRUE, 0); gtk_widget_show (scrollbar7); the user can grab hold of the top and/or second hbars. gary -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Voice By Computer (for Universal Access): http:/www.thought.org/vbc The 8.57a release of Jottings: http://jottings.thought.org Twenty-five years of service to the Unix community. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
need help getting this right
i'll append ~130 lines of C and gtk v2.0 or later. i found this
online in a much busier [and complex] example. for several days,
on and off, i messed around trying to get two independent horizontal
bars. i would guess that in total, i hacked away around 17-23
hours. this morning i threw everything away and started from
*scratch*. after about two hours of using EXtreme care, i got to
horizontal bars to work.
(by the way, this is for part of my menu-items Options dropdown.
i FINALLY found the program i had been looking for. Gespeaker. i
thought: Oh great; that's got all i need. BUUUT: Bzzt: it is is
python and i'm still learning that. )
what i need help w with is mostly =one=- thing: give the numbers more
=room=. only 0 and 100 are clear. the rest are displayed as if
torn [??]; i would like lots of vertical space between my three or
four horizontal bars. i've tried the 'separator' bar. no joy, at
least AFAICT.
thanks much in advance,
gary

GtkButtonBox is just a special type of layout widget that keeps the buttons all the same size. You can adjust it to put all the buttons to the right, left, center, or evenly across the dialog box. Or you can use a regular hbox, set the padding and margins the way you want, and use gtk_box_pack_start() to put them towards the left, and gtk_box_pack_end() to put them towards the right. And if set the HOMOGENEOUS property, they will all be the same size. I suggest you run glade-3 and just play with the layouts to get a feel for how you can use layouts to accomplish what you want. You can drag and drop the layouts, put layouts in layouts, and drop buttons and things in to see how they space out, etc. http://www.micahcarrick.com/gtk-glade-tutorial-part-1.html, particularly part 7 that talks about packing and layout. You might even want to use glade to develop your GUIs and then use GtkBuilder to build them in your program without using code (it is easier once you figure out how it works). Building GUIs with code is still okay, but for large programs it's just too much of a pain! the thing is that i'm almost done with the program. well, modulo the options that the user has to set. i should have that worked out pretty soon. the only thing in File is Want to Save and Quit. with these dialogs in Help, it is just a matter of how nice i want things to look; very nice or somewhat clumsy. --regarding the buttons, i figured that out about an hour ago except the buttons are on different levels. i'll check out gtkbuttonbox and more. just not now; time for a break:) ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Voice By Computer (for Universal Access): http:/www.thought.org/vbc The 8.57a release of Jottings: http://jottings.thought.org Twenty-five years of service to the Unix community. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

suggestions on user config?
if you look at my code, it is as if espeak takes a truckload on
inputs, but really, there are only four:
-a [integer], -p [integer], and -s [integer]. according to the man
page for espeak, the -a/amplitude is from 0 to 20, default = 10;
the -p/pitch is 0 to 99, default is 50; and the -s/speed is words
per minute, default = 160. i'm using -g for gender. 0 is
neutraal. {nothing on my man page... .}
i would like suggestions on what to use to get the above options.
this is why i was searching for the speech app that has the slider
with ticks to indicate 10, 20, 3e0 ... 100 and so forth.
thanks for any input here.

In my little app I shared with you I chose not to have a menubar because it wouldn't have served any purpose. The current feature set is entirely reached via the UI in the main window. To close an app you could set up a shortcut key, usually Ctrl-Q, or sometimes Ctrl-W (window close) to terminate your app. Or let someone just hit the (X) button. Either way, very few people probably use File-Quit to quit. I know I don't. I use Ctrl-Q or Ctrl-W most of the time. Or close the window with the decoration. Menus do have their place of course. i do, use the File-quit, but as a last resort :-| a more rational use of a top menubar would be to give the user the choice to look at the options that espeak has: from gender to speed of speech to pitch.

I think in Ubuntu's Unity desktop the menubar is grabbed out of the
window and placed at the top of the screen. I could be wrong, though.
i've seen this and don't like it; i'd rather have every
Konsole have its own menubar. same with other GUI apps.
hmm. i'm still not 100.0% certain of this, but here is what
i've learned: in my compile script is `pgk-config --cflags --libs
gtk+-2.0`
that follows the gcc [stuff]. at least for ubuntu linux, i
need the `gtk-config --cflags [etc]`
according to what i can find on google, it looks as tho the
gtk-config command might only be available for the i386 ...
i took a simp;le gtk C src along with my compile script and
scp'd them over to my netbook. ran the script and exec'd
the binary. it produced a gtk widget with the menubar and
File Help and twso buttons in the lower left.
it may be hthat ubuntu is moving toward gtk-3.0 and
dropping the older releases. {?}

Me too but OS X does this. Aparrently, it does not matter nowadays
whether something makes sense or not but only whether OS X does it...
Some methods how to disable it are described here:
http://www.webupd8.org/2011/03/disable-appmenu-global-menu-in-ubuntu.html
In short, get rid of it globally:
sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt
or disable it while running specific program:
UBUNTU_MENUPROXY= program args...
at least for ubuntu linux, i
need the `gtk-config --cflags [etc]`
You definitely do NOT need gtk-config. It was used in Gtk+ 1.x and has
been replaced with pkg-config.
it may be hthat ubuntu is moving toward gtk-3.0 and
dropping the older releases. {?}
It should not be directly related to these issues although Gtk+ 3.x
indeed will bring new methods to do unexpected things to menus.
For me this all means classical application menubars are dead and I will
not use them in newly written programs at all.

Wouldn't it be easier to simply add an editor window to your program?
Use for example, the GtkTextView widget. You won't have to spawn
external editors, and always have the text available.
You can even implement cut/copy/paste, re-use recent text, etc.
Also, you launch the reproduction as a thread, and permit editing while
permitting edition.
Thread or process, it doesn't matter. GTK's g_spawn_async can do the job.
As for the first, as Gary explained to me, whatever editor he uses has
to be able to expand abbreviations. He can only type slowly, and
automatic abbreviations can speed up his typing dramatically. He
already has a nice system in vim that works for him, so he wanted to use
that here. GtkTextView does not have completion capabilities. However
GtkSourceView does. I've written a demo program for Gary that does use
GtkSourceCompletion to do the abbreviations. Another option is to embed
a vim widget (Pida embeds gvim somehow) somehow, if he's got to remain
with vim.
the reason for sticking with gvim or kate [which is another
vi-like editor] or another fork-able editor--the reason is
that i'm assuming the user cannot speak--for w hatever
reason--and the cleanly spawned editor would give him a
change to reply to whomever he was talking to.
he wouldn't have to clear the screen of his last-typed
words:

Super! thanks. [[jon closes his netbook and follows the clerk. ]]

there are an endless number of ways this gtk app could be

it might be helpful for people recovering from strokes who

have temporarily lost the ability to sync up. they may be
able to use this application to help them remember more
quickly.
this may be my chance to learn python, :) i know what i
need to code, just not the intricacies of gtk {yet!}
finally, altho i want to add the std menubar with [File],

need help in looping many times...
thanks to a slew of you guys assistance, i have the beginnings of a gtk written in C. i'm into my 6th week of this and keep getting ideas from a few on this this. vbc.tgz is enclosed; find someplace to save it, untar and make the 'vbc' binary. the button i have a question about it labeled Run Text-To-Speech. since this program is for people whose speech is impaired [or lost] and ==can== type, the user click the Run button. you need gvim and espeak to make things work. After clicking Run, gvim will open a GUI editor. the user who needs help speaking simply types what he wants to say, then hit [ESC] and :xenter. the computer then speaks whatever he had typewritten. right now, the user has to click and wait for gvim to spawn before he can type. how can i code this so that the editor pops up over and over *while waiting for the user to type.* if the user typed nothing, the program would pause. i actually did this is a separate function several days ago, but the main window always went grey after about three invocations of gvim. i am assuming the gvim [or kate or kwrite--any editor] must be called from a callback; i'm just not sure why. michael torrie and at least one other suggested that i use the while(gtk_events_pending) iteration loop. that may be the magic code ... or maybe not! if the speech-impaired user lost his voice to laryngeal cancer or deafness---in other words, cannot speak at all, then maybe he is shy and having to click-and-speak is no big deal. but what if you have your laptop with you and run into old friends. there could be hundreds of type-and-speak times. that could cause shoulder pain in moving from mouse to keyboard and back. then the idea of the automatic editor popup occurred. tia, of course, for any insights. the more i learn about gtk, the more i see how advanced it is over XAw, the athena toolkit that i used years ago, :) gary -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Journey Toward the Dawn, E-Book: http://www.thought.org The 8.57a release of Jottings: http://jottings.thought.org Twenty-five years of service to the Unix community. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

CC: GTK Devel List gtk-app-devel-list@gnome.org
Gary, based on conversations in the past about what you are trying to
do, I whipped up a little program that just might approach what you are
trying to do. If I understand you correctly, you wish to do the following:
- type text in an editor where abbreviations are expanded (by macros in
gvim or some other mechanism in another editor) to full words or
phrases, so that you can compose text faster, even with disabilities.
- speak the written text with espeak the text
- save what was spoken so you can load it back up and re-speak it, or
edit it and speak it again.
Seems like the big requirement is the ability to use abbreviations. I'm
not clear on how gvim does it for you, but the GtkSourceView2 widget
(not part of GTK, but all distros have it and it's fully integrated with
GTK) supports what are called Completions. They are intended for use
with programming, but they also can function as an abbreviation
mechanism. As you type, when an abbreviation is detected it can pop up
a suggestion that pressing enter will accept, or keep typing and the
suggestion will change or go away. Multiple suggestions can be made as
well.
So, here's my program. It's written in Python, since python is one of
the absolute best languages for rapid prototyping. This app did not
take much time to write, and it gave me a chance to refresh my skills
and learn how to use some more advanced GTK widgets like the TreeView.
Anyway, my program does not save what was spoken to disk, though that
can be added very easily. It does save what was spoken during one
session of running the program. As well, currently abbreviations are
hard-coded in completion.py, but again that could be saved to disk
easily. There's already a dialog for editing the abbreviations within
the program.
I believe it does most of what you require, and could be expanded very
rapidly. It is written in Python, but now that the prototype is made,
it could be converted to C easily, though there is no advantage in doing
that really. The GUI itself was made in Glade-3, so the actual widgets
and the magic behind the TreeView is hidden somewhat. Glade has the
advantage of making it very easy to rapidly develop the GUI.
Anyway, the source code is here:
git repo: http://www.torriefamily.org/~torriem/tts_assist.git
tarball: http://www.torriefamily.org/~torriem/tts_assist.tar.gz
You will need to install pygtk2 and gtksourceview2. On Fedora those are
the exact package names.
I think it would be fun to develop this further (perhaps porting to
GTK3), but I thought I'd post what I had. If it's not useful, that's
fine. Python makes coding fun and very fast!
Michael
this sound very much worth looking into and i will ... just
as soon as i figure out what is causing my gtk app to dim.
{by the way, two+ days without power up here in metro
seattle in what cause the delay in responding. i was
getting ready to google up the async call the first time
the power went South... .}
i am still resty with gtk and thursday night it occurred to
me that sinced i was beginning with the Run button, that
*that* might be where i should jump into a loop. rather
than from my voice_edit recursive function.

That is probably what you have to do. If I understand what your code does (and how) then while gvim is running your app is *not*. Your app is blocked and waits until gvim terminates. The same for espeak. i think you have it nailed! [g]vim creates a .SWAP file in the pwd; so since gvim creates .talk.N.txt.swp while the textfile is being types into, i do a while(!done) check on the .swap file. then i do a second while loop while talk.N.txt exists. finally, espeak [flags] | aplay speaks the words in the text file. [ i tee the output of espeak and hand it off to aplay because of strange driver bugs here on my desktop.] You need to use a function such as g_spawn_async() to execute it. Then it depends how you communicate with the programs. If you just want to know when it terminates use waitpid(). thanks much. i'll check g_spawn_async() to see how it is used. i hadn't thought of any of the flavors of wait; everything has worked: gvim//write-quit/espeak a dozen times. but the gtk app is greyed and the quit button doesn't work! gary Yeti -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Journey Toward the Dawn, E-Book: http://www.thought.org The 8.57a release of Jottings: http://jottings.thought.org Twenty-five years of service to the Unix community. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

The question remains: how? what am i missing to display some miscellaneous words in the text window? you're right. i do not want to type anything into the text file. instead, i want to fork gvim and use thaat to type into. it seems likely to work if i can have buttons in the textfile. Buttons in the textfile? I know you don't want to type anything in a text file. What in the example I showed you was typing in a text file? Not quite sure what you are trying to do with vim, but if I understand it at all, what you are describing is not using fopen (as you stated before). popen maybe. If you'd clearly communicate what you are trying to do that would help greatly. Since you don't seem to understand GTK+ that well, perhaps you should communicate your needs without using GTK+ terms and objects. In other words, instead of trying to describe how you would do it with your understanding of GTK+, just describe what you want in overall, non-GTK+ terms. So with that in mind what I understand you need is to be able to interactively run vim, be able to send vim keystrokes, and display it's output in a window. Is this correct? If not, then nothing I say will be of any help to you in this e-mail. My gut feeling is that you are barking up the wrong tree. What you are trying to do is possible in plain GTK+ but it's not a matter of simply writing text to a TextView. You need to implement a Linux PTY (pseudo terminal) that vim can run in, and then implement some form of terminal emulation. i am reallty not doing anything that arcane. the nutshell of it is that in while (!done loop) gvim [ or another editor that can use abbreviations ] creates a series of text files. 1 to some N. what it written to each file is then read aloud via espeak -f; this application is an attempt to help those who are speech impaired or mute and have a small laptop. i have been smallish gadgets that lack a keyboard. my app is not targeted at people who would use the device that has a touchscreen [plus hard drive + batteries]. I' tried one of these things in 2003 and a later model in '09. my disability is fairly pronounced, but i could barely lift this box. i believe you could even play games on it. for me, the screen was not that easy to press. i prefer an actual keyboard. if i'm talking to people or a person i am hard to understand without a few weeks of getting used to my speech patterns; with a shell script that i put together in 20 minutes, i could type onto my EEE-900A and the computer would be my voice. i have been in touch with the people who are developing the $100 laptop that is being used globally. they said: sure, create a gui app that can be used by the physically disabled or deaf. this morning, i got gvim to spawn a Konsole; espeak echos what i typed. but while the display button (with other buttons) can find something i typed earlier, there is no way to close the display window. i need some means of putting buttons on the display window. + If you want to run an external command like vim (which requires a PTY) and drive it from GTK+, you really ought to look at the vte widget (http://developer.gnome.org/vte/). This implements a complete terminal emulator and PTY handling in a GTK+ widget. You can use it to run vim (directly), and send it keystrokes and have it displayed in a window. You can use the vte_feed_child() method call to feed vim keystrokes. The output of course is automatically displayed in the window. i may try this if i use kate. kate has some vi-like-isms. nobody added the abbreviations to kate. --then again, back in 1996 i bought a book XLIB BY EXAMPLE.

in ~/.exer, after your set cmds, you use abbreviations
like so:
ab u you
ab th the
ab thr there
ab i I
and so on. since my app only cares aboutsounds, you
can use they're, there, their with one string: 'thr'

Hmm. This is going to be very hard to do with GTK+ (or any other UI
toolkit for that matter). You are trying to drive a full blown
graphical app in its own right with your graphical app.
You could re-implement the abbreviations things you use in vim with a
standard TextView editor widget in GTK+. You could do this two ways.
Either intercept keystrokes and fill in the full word (easy to do in
TextView), or just keep everything abbreviated and then expand the
abbreviations when sending the output to espeak.
Or you could try to implement your needs as native vim code. Use Gvim's
facilities rather than try to hack your own in GTK+ and try to get them
to work with Gvim.
I'm coming back to my original suggestion. Instead of running gvim,
could you just run straight vim in a VTE GTK+ widget? I presume your
abbreviations are all defined in .vimrc. This way it at least integrate
with your GTK+ code. That's really the only way you're going to get it
to work even close to the way you describe.
I might hack together something here over the holidays. It will be in
python, but maybe it will help. You might want to try a bit of python.
There are way less non-alphanumeric characters than in C, so it would
be easier for you to type. Structure is done with spaces instead of
curly braces.
i'm just starting to teach myself python. it's a great
language, but after a billion years with C it's easier.
what if i gave up on tthe abbrevs? would that make life
simpler? --all i want is those butttons; [[muumble]]
Okay so you are trying to come up with a graphical program whereby you
can type something (say in a text box) and have espeak speak it so that
others can hear and understand you? Do I have this right?
i think so; it isn't rocket science ... i'll send you the
code with the gcc line if you 'd like.
Feel free to post GTK+ code here to this list and we can look it over a bit.
I'm starting to get a feel for what you are trying to accomplish. I am
glad you remain able to communicate fairly well through the written word.
Michael

Did you add 'hbox' to any container ('vbox' in your code example)?
nope. here is what i start out with:
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_position (GTK_WINDOW (window),
GTK_WIN_POS_CENTER);
gtk_window_set_title (GTK_WINDOW (window), VoiceByComputer);

vbox = gtk_vbox_new (FALSE, 5);
gtk_container_add (GTK_CONTAINER (window), vbox);
gtk_container_set_border_width (GTK_CONTAINER (window), 15);
below that i create a label and call update_label; then i handle
the alignment::
align = gtk_alignment_new (0.5, 0.5, 0, 0);
//gtk_container_add (GTK_CONTAINER (window), align);
gtk_widget_show (align);
then i get an hbox button and call show; after gtk_widget_show, i do
the button decrease/button increase code.
i'm stumped.
hbox = gtk_hbox_new (FALSE, 2);
//gtk_container_add (GTK_CONTAINER (align), hbox);
gtk_widget_show (hbox);
should i NOT be called the show() here?
thanks,

You can use -Wwrite-strings to catch that. your advice was right on target. i changed the gcc line, then checked if (prefix == NULL) printf(NOT NULL\n) early in main(). since i set prefix , the string printed to stdout. long-story-short, my test program works the way i want. Unforutnately, passing constant strings as various user-data-kind arguments or to g_hash_table_insets() then produces warnings too. okay; i'll watch out! Also learn to use valgrind; it would show you this problem immediately. a couple hours ago i installed valgrind and a front end. The next thing on my to-try list is to get the increase/decrease buttons together; this means reading up on the hbox stuff. i found one example somewhere last week and it looks tricky. --anyhow, thans for your keen insights. gary Yeti -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Journey Toward the Dawn, E-Book: http://www.thought.org The 8.57a release of Jottings: http://jottings.thought.org Twenty-five years of service to the Unix community. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Why cani i initialize prefix with a default string?
guys, i am appending a piece of gtk test code. it saves the
internal filename buffer for espeak -f %s ifbuf to run
on--to be the user's voice. if i set
static char *prefix = talk;
then back up and enter another string in the box at the
bottom, strange things happen. Anybody know where i am
messing up?
tia,
gary
PS. i am thru with the play button and callback, but
would like to understand my errors above first!

APOLOGIES!! [Was: Re: a couple questions...]
actually, this is primarily to john c, if i bundled up my broken piece of code and send it to the list as well. i was tried to assign a global string to static char *prefix; without accolating the space for the string. because this has to do with speech, my DEFAULT string was simply talk; but maybe the speech-impaired user wanted to use chat or do a quick x or xyz. annyway, long story short, before i can finish my callback like the one that john suggested, i have to make sure that the code withs with it's default. gary PS: NExt post will probably be where i messed up in the play callback. -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Journey Toward the Dawn, E-Book: http://www.thought.org The 8.57a release of Jottings: http://jottings.thought.org Twenty-five years of service to the Unix community. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
a couple questions...
two guys wrote the majority of this gtk widget code. it is
meant for the speech-impaired or mute. they type into the
editor spawned by gvim or kate, and when the file is written a
speech tool of the linux box is their voice. i keep track
of the file by inc or dec in case somebody they are
talking too didn't hear or understand part of the
conversation. if the user is a slow typist and has written
a few paragraphs, he just looks back and forth thru the
files to find the one that his friends want to hear again.
i'll need a play button and callback that invokes, say,
espeak -f on that file.
if this much makes sense, below in the C code.
tia for any insights.
cheers,
gary kline
