Re: Closing XTerm causes the GTK app to exit, inspite of disown/nohup on its PID - why?
Wild guess; use strace to look for a signal at the time the window is closed, and add code to replace the handler for the signal. For instance, to handle Ctrl+C gracefully in Python that uses GTK, some of my code does this; GLib.unix_signal_add(GLib.PRIORITY_DEFAULT, signal.SIGINT, callback) -- James Cameron http://quozl.netrek.org/ ___ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list

stBuf is an uninitialised pointer. g_stat will try to write to the
address; undefined behaviour results.
Try allocating some memory of the right size, and assign that address
to the pointer before calling g_stat?

You might ask on an fvwm mailing list, but fvwm does have a
NeverFocus method that can be applied to an application such as xterm.
http://www.fvwm.org/documentation/manpages/fvwm.html
But that would just fix your problem for xterm; to enforce focus for a
lock screen, there's more to do. Have a look at the code for other
lock screens to find out what that is.
Briefly, make a global mouse and keyboard grab, subscribe to window
visibility events, and when they occur raise the window above whatever
was stacked on top of it.
You could also adjust xterm sources to ask for focus skip; bit 0 of
_WIN_HINTS property.

Hey all! Does anybody have a copy of webkitgtk compiled without enchant, (via the cmake flag, DENABLE_SPELLCHECK=OFF)? or would anybody be willing to compile one for me? I'm on a laptop with a single-core and 1.9Gb RAM, so I did start the compile process, but it's just a little long!

GtkWidget focus line color
I am creating a GTK3 theme and want to have all indicator focus lines
a particular color in all states.
At the moment the focus lines uses the color of the widget state it is
on... for example:
.button {
-GtkWidget-focus-padding: 2;
-GtkWidget-focus-line-pattern: "\0\0";
padding: 1px;
border-width: 1px;
border-style: solid;
border-color: @theme_base_color;
border-bottom-color: @gradient_from_color;
background-image: -gtk-gradient(linear, left top, left bottom,
from (@gradient_from_color),
to (@gradient_to_color));
color: @theme_fg_color;
}
.button:hover {
border-color: @insensitive_color;
background-image: none;
background-color: @theme_selected_bg_color;
color: @theme_selected_fg_color;
}
When the mouse hovers over a button the focus line color changes from
@theme_fg_color; to @theme_selected_fg_color but I might want it to
stay @theme_fg_color (or perhaps another color set globally).
In GTK2 I achieved this using the pixmap engine and an png image:
image
{
function= FOCUS
recolorable = TRUE
file= "Others/focus.png"
border = { 1, 1, 1, 1 }
stretch = TRUE
}
I am not using any GTK3 engine and had hoped something like this would
have worked (it doesn't).
*:focus {
color: @theme_fg_color;
}
I am looking for something like an option
"-GtkWidget-focus-line-color" which doesn't exist or someone who knows
how I might achieve this. I don't mind if I have to use an image and
have actually been trying to use border-images and such but haven't
been successful.
Thanks

Question about a Gtk-WARNING message when running gedit
Hi gtk-list: I recently built and installed GTK+ version 3.6.4. This ended up 'breaking' my old RHEL system supplied version of gedit (version 2.16.0). So I went ahead and built and installed gedit version 3.2.6. This version works, but I get the following Gtk-WARNING every time I run gedit: (gedit:9928): Gtk-WARNING **: Theme parsing error: :5:10: Not using units is deprecated. Assuming 'px'. It appears to me that this may be caused by a call to a GTK+ function somewhere in the gedit source code using a deprecated call format. However, I don't know what to look for in the gedit source code. What GTK+ function would such a WARNING be associated with? Or is this caused by some other problem? Jim Tilton ____ Dr. James C.

Georgios Petasis
Thank you ... at least with that, so far I can display the selected
directory in the main window ... that is more than I had.
(for those not interested ... you may easily stop reading here ... thank
you)
What is the action, you ask?
(1) enter a search string (exact match, but not case sensitive)
(2) select a starting directory
(3) search recursively from there
(3.1) search first for a list of files ending in *.odt
(3.2) search each file on the list (found in 3.1) for the string
(3.2.1) make a list of matches
(3.2.2) display the match list in a scroll box
... or some variation of that.
I have odt2txt (downloaded and running), and I have a couple of (BASH)
shell scripts that complete the set. I put all three in /usr/bin. The
set works like this ...
(1) in a terminal window
(1.1) cd to /desired/path
(1.2) enter the following: searchODT string [string [string ...
[string]]]
(1.2.1) that is, at least 1 and up to 9 space separated arguments
(hard coded arbitrary limit)
(1.3) searchODT sorts out the string, combining all arguments into
one string
(1.4) searchODT calls depthODT, which generates the list (file) of
*.odt files
(1.3.1) search is recursive beginning at the 'pwd' where the
original searchODT command was issued
(1.4) searchODT then calls odt2txt for each entry in the list (file)
(1.4.1) the output from odt2txt is grep'd for the string(s) (grep -i)
(1.4.2) matches are put into another file for display
(1.4.2.1) it is possible to use: more, soffice, kwrite (and I am
sure others) for the display.
Other than argument count, there is basically no error checking at the
moment.
(scripts available, if interested)
The original project was to done to help my spouse, because dolphin
(file manager) doesn't seem to be able to search inside OOo documents?
And the current version functions well enough. But I though I might be
able to use this opportunity to learn some more tcl/tk.

Change in FileChooser behavior
Hello List, I recently upgraded GTK+ version 2.24.7 and discovered that the behavior of the FileChooser has changed. This change makes FileChooser very inconvenient to use. Previously, the file selection dialog would automatically show the files in the current working directory. Now, the file selection dialog automatically lists "Recently Used" files, and there is no option to select the current working directory. Apparently I am setting up my FileChooser incorrectly. How to I set up FileChooser so that it provides me with an option to look in the current working directory? I see that there is a member function "add_shortcut_folder" that I could use to add the current working directory as a shortcut folder (but then I would have to mess around with C's getcwd() function). But I didn't need to explicitly set the current previously. Is it a requirement that I explicitly set it now? If so, why was this change made? It seems this should be a simple thing. What am I missing? Thanks. Jim Tilton ____ Dr. James C.

Re: Remarks on gtk docs
Joost, and others, I tried learning to use gtk, gdk, cairo, pango, etc several years ago and was frustrated by the difficulty in getting good docs, sample code, etc. Even worse was finding that "constant change" meant me having to rewrite code fairly often. Note that I'm an "old guy" who has written code for a living since I was a "young guy". But this has been the most difficult venue in which I've tried to work. I feel and share your pain in producing something of quality and lasting value. I know it can be done, but I pretty much work alone, and it's not easy. I switched to writing my own set of "widgets" in C++ which more or less look and act somewhat like Java's AWT, but nowhere near as powerful yet. I've got simple projects like a telnet client working, but I feel like I'm mining gold with a fork. My one big question to this list is (and no disrespect is meant), is there a elist similar to this one dedicated to Xlib programming? This list does have many very talented people, some of whom I'm in awe of.

Re: Not getting which mouse button is pressed on button-press-event
Just tried it and verified most of the answer, via something I'm playing with;
UINT ejEventManager::getButton () {
return currEvent.xbutton.button;
}
1 == Left mouse button
2 == Right mouse button
4 == scroll up
5 == scroll down
Wasn't able to emulate middle button on my 2-button mouse (project for another
day, perhaps). Can't verify 6,7, but perhaps it's time for me to buy a better
mouse. I wonder, though, if this might be useful with a joystick (left, right).

Re: OT comprehending large application (was What, in detail, the GDK do)
One way might be to write a "real" application (even if it's just a "Hello World" display) and "drill down" through the source code to see how this seemingly small amount of code works at lower and lower levels. While this sounds easy, it's quite a learning experience, and IMHO is well worth the time spent. Ed James On Tue, Dec 29, 2009 at 8:44 AM, Patrick wrote: ... > a case of sticking to a small section?

Re: What, in detail, the GDK do?
A good book on programming for the X Window System is "Xlib Programming Manual" by Adrian Nye (O'Reilly & Associates, Inc"). I've been using it to try building my own object-oriented "toolkit" using C++. My stuff will never be "production quality", but it really helps understand what is happening at low levels.

Re: Memory problem
Guessing here...try adding

Re: Memory problem
Don't know if this will solve your problem but I found:
"gdk_color_alloc is deprecated and should not be used in newly-written
code. Use gdk_colormap_alloc_color() instead."
My guess is that gdk_color_alloc allocates memory which isn't being freed up
and thus accumulates, but I didn't dig very deep. This might also happen
with the newer function.

Gio (?) filemonitor/inotify problem (really annoying)
I am using Gnome 2.24.1 with GTK+ 2.14.4 / GLib 2.18.2. Ever since ive updated to gnome 2.24, Nautilus fails to monitor directory changes (file creation and deletion) but only after some time (after 20 minutes or so). I only noticed this on the desktop folder initially which is why I posted a bug to nautilus (http://bugzilla.gnome.org/show_bug.cgi?id=557550), however I realised after that this is actually happening to ALL folders, its just that i dont often keep a nautilus folder view open long enough for it to happen. After some digging through the nautilus source, I could not find any reason as to why it would happen since the changes to the file monitor code is minor compared to 2.22. So before I pursue any further I would like to find more information as to why this is happening as it is most likely a gio issue rather than a nautilus issue. My current setup is a aufs overlayed live filesystem on a slackware core, with self built gnome (ive been building gnome since 2.18 with no issues so far). I have considered the possibility of it being a kernel/aufs problem, but I have tried my older setup of a 2.6.26.6 kernel and an older version of aufs (both of which I used back in gnome 2.22) to no avail as well as mailing the aufs developer who could not see any problems with aufs that could cause this. It appears that this is definetely not a kernel issue. I am using self built vanilla 2.6.27.4 kernel (SMP 4KSTACKS), dbus 1.2.3, hal 0.5.11, gamin 1.9, GTK+ 2.14.4, GLib 2.18.2. The reason this issue is really annoying is that theres nothing I can do to track down the problem; no crashes, no logs, no warnings, nothing... it just silently screws up and it ALWAYS happens, the only thing that varies is the amount of time it takes before the problem appears (sometimes it will work for an hour before breaking). Therefore, as a last resort, ive come here to ask if anyone has any other ideas at all that I can try to get to the bottom of this very wierd and annoying issue. ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Building GLIB 2.12
Hi, I'm new to this. Can someone tell me why when I build GLIB 2.12, it creates libraries of version 2.0?!? When building using ./configure --prefix=/opt/gtk2 GLIB builds fine, but then checking the lib directory inside the prefix reveals the following files have been created: gio libglib-2.0.la libgmodule-2.0.so.0 libgthread-2.0.la glib-2.0 libglib-2.0.so libgmodule-2.0.so.0.1600.0 libgthread-2.0.so libgio-2.0.lalibglib-2.0.so.0 libgobject-2.0.la libgthread-2.0.so.0 libgio-2.0.solibglib-2.0.so.0.1600.0 libgobject-2.0.so libgthread-2.0.so.0.1600.0 libgio-2.0.so.0 libgmodule-2.0.lalibgobject-2.0.so.0 pkgconfig libgio-2.0.so.0.0.0 libgmodule-2.0.solibgobject-2.0.so.0.1600.0 Now, correct me if I'm wrong, but shouldnt the version numbers be 2.1.2, not 2.0?

Re: g_main_loop
Just a guess, but I'd try putting a function in Thread 1 that emits the signal, but call that function from Thread 2. This way, Thread 2 controls when the signal is emitted, but the signal is still handled by Thread 1. Never actually tried this myself, though, so I don't know for sure if one thread can call a function in another thread.

Re: Re: Editable Label Widget
My problem with using a GtkEntry is that I need the label to be multi-lined. I don't want to use GtkCellView because, when I edit the text, it will resize the widget. It is possible to have hundreds of these widgets in a column, so that would be a rendering mess. I had originally used the idea of switching between a GtkLabel and GtkEntry. There are a few problems with this. First, you still have the resizing issues. The user can't see the whole text when it is in a GtkEntry, so it will be difficult to edit longer texts. Also, you have to keep two widgets around, which takes more memory. I had created a very bad implementation of the GtkEditableLabel widget that just resets the text on user input, but this is obviously not the optimal solution. Plus, I am looking at creating something that would be more versitile, and not depend directly on my specific application. Anyway, I'm leaning toward just creating a new widget so that I don't have to deal with the selection info. This will allow me to reuse some of the EelEditableLabel code. (BTW ... hello Ana!)

Editable Label Widget
Hello All, I have an interest invested in an editable label widget because of an application I am working on. Because of this, I decided to work on the widget myself since the project seems to have been dropped from the list of priorities. On Bugzilla, there is an implementation that was written in 2005, but it is not acceptable because it uses more than the available signal padding slots from GtkLabel. It is quite obvious that the way to go is to use the GtkEditable interface in a new widget called something like GtkEditableLabel. However, there are two different approaches that I've come up with. One way to implement this widget would be to derive it from GtkLabel. This would allow the widget to inherit all of the code from GtkLabel, but may cause problems because of hidden data and the fact that GtkLabel already handles selections in a different way. The other option is to do what EelEditableLabel did and just derive from GtkMisc. This would add a little extra baggage because of reimplementing a few of the same features. However, I think this may be the better way to go in terms of API and speed of the widget. Does anyone have any thoughts on this issue, in one direction or the other? --- Andrew Krause ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
Release of Foundations of GTK Development
Hello, My name is Andrew Krause, and I am the author of a new book about GTK+ entitled "Foundations of GTK+ Development". I know for many new GTK+ developers, it is difficult to learn the toolkit because there aren't too many tutorials available. Therefore, I decided to write this book, which covers almost every widget available in the release of 2.10. Some of the topics include: * Basic widgets such as labels, buttons, dialogs, entries, etc. * A large portion of GLib including files, pipes, and dynamic modules. * Two chapters dedicated to the GtkTreeView and GtkTextView widgets. * Menus, toolbars, pop-up menus, Glade, and libglade. * How to create your own widgets and interfaces. * Widgets introduced in GTK+ 2.10 such as printing and status icon. I also setup a web site to accompany the book, which is found at http://www.gtkbook.com/. If anyone picks up the book, I would love to hear what you think about it! --- Andrew Krause ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
RE: How do you develop you GTK code?
I have responsed to some this before, but here goes.
1. Use Glade to create and maintain the XML GUI interface descriptions.
2. Use libglade to parse and create the interface at run-time and you
take care of writing/maintaining your event handlers and other such
stuff.
This process keeps the GTK Gui stuff cleanly interfaced to and separated
from the rest of the code (the really difficult parts of a project)which
you or someone else MUST write and maintain. This formula is almost
bullet proof when jumping from Windows to Linux or back.

Right, first of all I dont think its correct to suppose that generated
code is anyone's idea of "how it should be done", generated code is a
mechanical spew of "code that works" and should NEVER be used as an
example or reference implementation.
My opinions about glade are biased because I maintain glade, but my
opinion anyway: glade is not an IDE, its a user interface designer -
adding application data and modeling of that data is not a desirable
thing, you want to keep your user interface in one corner and your data
in another - not mix them up in one big pot of spaghetti code.
If you have concerns about dynamic portions of your interface, I agree
they should mostly be done by hand, but wait - glade can still help you
here, say you have a hbox with a label and an entry as was previously
described, you can always put one instance of that in your glade file
and loop like so:
for (i to ... dataentries) {
xml = glade_xml_new (..."dataentryitem"...);
widget = glade_xml_get_widget (xml, "dataentryitem");
/* ... pack into your program somewhere by hand ... */
g_object_unref (xml);
}
This might or might not make sence depending on the application, but it
does have the advantage of keeping your UI dynamic, if you need to add
an item/label/separator or whatever to that subhierarchy than you dont
need to edit or compile code to update your interface.
I also believe that following a template design might be good for a dumb
little CLI wrapper in a GUI - but if you are really developing an
industry grade application then please use your brain and understand the
code - using libglade for your interface is a good thing because it
defers all the repetitive rigid GUI building code to a library that
takes care of it for you - it also allows you to use YOUR OWN design
that is appropriate for your own application, either by loading dialogs
on the fly or at initialization time - keeping pointers around for the
widgets that you need referenced by name, or by using lookup_widget()
types of paradigms - point being - you are the author of your
application and the sources are in your hands, you should be able to
organize your code in a way that suits the application at hand.
For a good reference implementation - I've repeatedly been pointing
people in the direction of the DevHelp sources, since IMO they use a
sound OO design and a very practical use of libglade (its also very
simple code to understand).
Just my 2 cents, cheers,
-Tristan

spinner widget
I've been working on a spinner widget that is basically just the spinner portion of a spinbutton. Although the spinbutton handles numbers fairly cleanly, it doesn't seem to work well when trying to use it for other purposes. Although you can use the signals to have it display text (like the days of the week example), it does not handle user typing in a value well. Also, since there is no way to change how it looks, it always appears as an entry that the user can type in. My solution to this is a stand-alone spinner widget. The spinner will just appear as a pair of arrows and hold a double value and the developer could use that value to control a plain label, image, or anything else. The spinner as I have written it derives from GtkRange and has "wrap" and "snap_to_ticks" properties (the same as the spinbutton).

I find that I've been through a few iterations of "like Glade, hate Glade". At first, I thought it was brilliant. Certainly the fact that you can easily set tons of properties, etc, was just the cat's meow. Then, as I started building up more complex and especially dynamic user interface elements, I found Glade was getting in the way. Too much trouble. One big pain is naming the widgets in Glade and then ensuring that the widgets you lookup code side match. Really messes you over when you do refactorings (which, working in java-gnome as I do, is something one does A LOT via the wonders of Eclipse et al) [at that point, however, I'd actually settled on some programming conventions whereby it is transparent whether an application window is code derived or glade derived. The wonders of subclassing. So, now, it doesn't really make any difference which I do] So then in a new application I decided "well, forget Glade" and started doing everything programmatically. And then I realized that I was having to deal with coming up with variable names for each and every bloody Label, and that was a real pain in the ass. So the conclusion I settled on was to use Glade for as much scaffolding as possible, thus saving the object pressure of proxies being created for not much at all, but not to try and do anything even remotely complicated in Glade, preferring to hand off and switch to code at that point. And, no doubt, I'll be of a different opinion next month. :-) AfC Sydney -- Andrew Frederick Cowie Chairman Operational Dynamics Consulting Group http://www.operationaldynamics.com/ Management Consultants specializing in strategy, organizational architecture, procedures to survive change, and performance hardening for the people and systems behind the mission critical enterprise.

Can anyone suggest a work-around? Thanks, James ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
GDK Events
Just a quick question ... there are a ton of event types like GDK_CLIENT_EVENT which corresponds to GtkWidget's client-event. I was able to find matching signals for most of the event types, but I can't find them for the following: GDK_DRAG_ENTER GDK_DRAG_LEAVE GDK_DRAG_MOTION GDK_DRAG_STATUS GDK_DROP_START GDK_DROP_FINISHED GDK_SETTING GDK_OWNER_CHANGE Are there associated signals, or do they all just use the _event_ signal?

treeview drag icon appears black using gtk 2.8.18
Hi all, I have recently upgraded from gtk 2.4 to 2.8.18 on Win32 and have noticed that the treeview drag icon now appears to use a black background colour. This makes the icon undeadable as it rendered as black text on a black background. Are there any new style properties or other changes in 2.8 in this area?

GTK File Chooser: Managing files via tags
Hey, This is a concept I thought of this afternoon, it's a slightly different way of managing files, and one that I think could be quite popular. This isnt a replacement for a directory tree, but more something that can be implemented at a software level and complement it quite nicely. If anyone here has used del.icio.us, flickr or technorati in the past, you would know how it arranges things, via tags. Each item has a range of one word tags. I considered using this approach for files this afternoon, and quickly created this mockup in glade. https://iphitus.no-ip.org/images/gtktag.png You save a file. You type in tags when saving the file. Those tags are available in the side pane along with bookmarks. You click a tag, the file chooser lists all items that are tagged with that. The tags of all the files could be stored in some sort of file in the user's home directory. By having tags like that, implemented in the GTK file chooser, they would become immediately accessable to every GTK app out there that uses it. Gimp, Gaim, Abiword, Firefox, Gnumeric, etc. Think of how much more effective a way of managing files it would be. You'd no longer be searching for a file, or wondering where you saved it, so long as you tagged it right, you'd be fine, hit the tag, pick the file. Is anyone else interested in this idea and possibly implementing it?

Ben,
It's not really OLE, but XWindow reparenting, which was around long before
:-) I could put the whole thing somewhere if people are interested,
otherwise here's a quick outline.
You need a package named "gnuplot_i" (written by N. Devillard). It's a
few hundred lines of C code that handles all the details of running
gnuplot in a pipe, and encapsulates gnuplot commands for e.g. an xy plot
into a function call. I've improved on it a little, since I've used it
regularly for doing simple plots within a program. but the original
should work.
Do the necessary gnuplot_i setup, giving it a unique title:
sprintf (cmd, "-geometry 800x600 -title '%s%d'", argv [0], getpid ());
h1 = gnuplot_init (cmd);
and use GTK to make your GUI. Create your plotting area as a socket, set
its size, add it to the gui, and eventually call gtk_main ().
sock = gtk_socket_new ();
gtk_widget_set_size_request (GTK_WIDGET (sock), 600, 300);
gtk_box_pack_start (GTK_BOX (main_vbox), sock, TRUE, TRUE, 0);
In your "redraw" function (the one that actually does plotting, create
your plot from data, and call one of the gnuplot_i functions to draw it.
This will pop up an X window.
Now you need a function that uses XQueryTree and XFetchName to scan the
window list for the gnuplot window (which will have the unique name you
created). This returns an X Window ID. Then you just call
gtk_socket_steal and the plot window gets sucked into the GUI app. Note
that you do the search only once, and (at least on my system) have to sleep
for a bit before looking for the new window. So the code looks like this:
...make plot...
if (first)
{
sleep (1);
xid = GetXWinID (title);
}
if (xid != 0)
gtk_socket_steal (GTK_SOCKET (sock), xid);
first = FALSE;

Ali, Thanks. I'll have a look for future reference, but I figured out a quick & dirty hack that does what I need. I have the GTK menu program start gnuplot as a pipe, then re-parent gnuplot's plot window into a GTK widget. So I stuff gnuplot commands & data into the pipe, and the resulting plot shows up where I want it. Constructive laziness :-) James On Mon, 7 Feb 2005, J.

Plotting, text drawing, etc.
Ok, dumb question #2. Is there a package that will let me do basic plotting within a GTK window? I found one called GtkPlot, but it only seems to link with GTK 1.x, and I can't find any documentation at all for it. If not, where can I look for information on doing graphics text? I have a lot of miscellaneous routines around that I could adapt, except that I can't figure out how to draw text at a specific size & angle, as would be needed for e.g. axis labels.

How to static link a program?
Hi, OK, this is probably a dumb question, but I can't find the answer. How can I statically link a Gtk program? That is, I've written a program that uses Gtk graphics (and the GtkGL extension widget to allow OpenGl). It works fine on my personal Linux boxes, where I have control and can install the shared libs. Now I want to run it on our Linux cluster (and other people may want to run it on their machines). I have no root access there, and very little say in what gets installed. So how can I statically link my program (or at least the GtkGl library part of it) so that the executable will run on any system? There doesn't seem to be a make or configure option to even make static libs... Thanks, James ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Is this concept true for GTK signals in general? It depends entirely on the signal and property in question. For signals in GTK+ itself, generally yes (I don't know of a counter-example within libgdk/libgdk-pixbuf/libgtk offhand). Outside of GTK+ it depends entirely on the code given. GObject's "notify" signal, for example, is always emitted when set_property() is called (so "toggled" will only be fired when the "active" property has changed, whereas "notify::active" will be fired anytime someone calls 'g_object_set (button, "active", someval, NULL);' -- Peace, Jim Cape http://esco.mine.nu http://ignore-your.tv "If even one reporter had stood up during a pre-Iraq Bush press conference last year and shouted, `Bullshit!' it might have made a difference." -- Matt Taibbi, New York Press signature.asc Description: This is a digitally signed message part ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

"toggled" is emitted whenever the "active" property changes (which may happen as a result of user interaction or calls to gtk_toggle_button_set_active/g_object_set), whereas "clicked" is only emitted when the user actually clicks on a button (or, I think, uses mnemonic shortcuts). -- Peace, Jim Cape http://esco.mine.nu http://ignore-your.tv "If even one reporter had stood up during a pre-Iraq Bush press conference last year and shouted, `Bullshit!' it might have made a difference." -- Matt Taibbi, New York Press signature.asc Description: This is a digitally signed message part ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

The options are for passing metadata to the png module to use when
saving. You should be able to call gdk_pixbuf_save() with a NULL "..."
without it crashing (the savev requires an strv array, though the first
element in the array can be NULL)
e.g.:
char *keys[1] = {
NULL
};
char *vals[1] = {
NULL
};
gdk_pixbuf_savev (pixbuf, "some-filename.png", "image/png", keys,
values, NULL);
or
gdk_pixbuf_save (pixbuf, "some-filename.png", "image/png", NULL, NULL);

Re: g_value_new Macro?
On 27/08/04 10:56, Ryan McDougall wrote: I spotted where the docs say it must be zero init'd, but I can't see in the source *why* thats needed. I guess so you don't call init on a value that has already been init'd without calling reset first. Well, the code in g_value_init() is checking whether the type field of the GValue is zeroed out. It is right there in the code. Perhaps its my ignorance of GValue, why is memory allocation GValue's problem, thus necessitating an unset function. Shouldn't I dealloc my own pointers? A GValue can be used to hold an arbitrary value, including things like strings and GObjects. In the case of a string, the GValue holds an allocated string so not calling g_value_unset() will lead to the string being leaked. In the case of a GObject, you will get a reference leak. Tommi mentioned this in his reply to you. If the GValue is allocated on the stack, you only need to g_value_unset() it. If you've allocated it on the heap, you will need to free the GValue itself. For some internal code, I prefer to pass a heap allocated GValue pointer to some unnecessary copies of stack alloc'd GValues, so I use it outside of the tutorial (which can be changed). Basically I don't see any reason *not* to add it once the g_new0 bug is fixed. When passing a GValue into a function you call, you'd usually pass it as "&value". Note that this won't work if you want the value to last longer than the scope you defined it in. In practice, this isn't a problem for the existing use cases (also, GValue isn't really that good a choice for long term storage). [also note that doing a straight copy of a GValue is an error in most cases. If you unset one copy, it will invalidate the other].

Maintaining socket connections
Folks, I'm working on a pair of processes, one multithreaded and one single-threaded. The multithreaded process monitors incoming data on a TCP socket and a UDP socket, captures the data as it comes in and cleans it up, then writes it through another TCP socket to the second process. I am running into problems with that socket just closing off intermittently. Both processes are still running, but the data stops flowing. No errog log output to indicate that the socket is broken, nothing. It just stops working. The receiving process tries to read the socket and gets nothing, and the sending process stops writing packets because the socket is no longer writable. I've got code in place that is supposed to close the socket and reconnect, but it doesn't seem that it ever gets triggered. On the receiving end, I'm just using vanilla socket code; on the multithreaded side, I'm using gnet and giochannels. This code originally connected through a UNIX socket but I'm trying to make it network-capable. The UNIX socket version would stay up for literally MONTHS at a time. I MUST have that level of stability. Am I wasting my time? Is glib and giochannels not capable of providing that? Can anyone point me to an app that successfully uses them to maintain a *constant* connection, with automatic reconnection if the connection is somehow lost? thanks, Jim ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

scroll bars and sorted tree views
I'm having trouble getting the vertical scroll bar of a sorted tree view
to clamp to the top while adding new data. When the slider is at the top
I want the slider to stay at the top after the new data is added. When
the slider is not at the top, it should stay where it is after the new
data is added. (Basically I want it to act like Mozilla Mail sorted by
descending date.) I've tried playing with the "changed" and
"value-changed" callbacks of the adjustment, but I haven't gotten
anything to work properly.
Any advice?

The order of functions called when creating a GObject is: base_init() [called once] class_init() [called once per class/subclass] constructor() +- In this func must chain to parent first, to actually allocate the object. That calls +-> instance_init() +-> set_property() for G_PARAM_CONSTRUCT properties. +- Then your constructor code, which comes after the chain-to-parent call. set_property() for non-CONSTRUCT properties.

Re: TreeView cell editing
I'm actually using the standard CellRendererText, but I would like my
application to have a bit more controll over the gtk_entry while the
cell is being edited. I can't seem to find any methods of any object

It appears that your example is from a custom renderer. I wouldn't
expect to have to subclass the renderer in order to do this.

Well, may it won't help (because I've done this on C++ in gtkmm), but

You can do it by moving cursor to another cell without editing it (and,
maybe, moving the cursor back to the origin figured out with
gtk_tree_view_get_cursor). It works for me.

Sorry, I wasn't very clear. What I meant was "it should work so that all
you have to do is add 'text/x-uri'list" to your TreeView, but it doesn't
work that way now and will require a patch to GTK+ to do so." Since
you're apparently familiar with TreeView DnD (I'm not), I was suggesting
you just dive into the GTK+ source and add the appropriate drag targets
to the GtkFileChooser widgets yourself (attaching the resulting diff to
a bug in bugzilla so it won't get lost). Since all the GtkFileChooser*
widgets use the same code (in gtkfilechooserdefault.c) to draw the list
in the chooser widget, it should be a trivial patch to write.
And, I should probably also apologize if that sounds presumptuous, it
just seems like something best done at the GTK+ level, and F/OSS makes
doing that easy :-).

SpinButton question
I'm writing an application that has a SpinButton widget in it. The SpinButton will have a very large range of values and I want to disable the ability to right-click on an arrow to max or bottom out the value (or at least treat it as a single step or page). I've tried blocking right-clicks through the button press callback, but that also disables the default standard context menu for the text area as well. Also, since the SpinButton doesn't tell me where the arrows are located within the widget, I can't tell where in the widget the click occurred to see whether the right-click should be ignored. Since I can "disable" page-up and page-down functionality by setting the paging size equal to the step size, I would think that I should be able to disable the maximize and minimize functionality as well.

GNU- libc systems should have /usr/lib/gconv/ISO8859_1.so and a line in /usr/lib/gconv/gconv-modules which reads something like: "module INTERNALISO-8859-1//ISO8859-1 1" "INTERNAL" is an alias for UTF-8. Please note that gconv-modules should not be edited, it is part of glibc -- so if you're using a glibc-based system, this is either a bug in the package or the installation. I'm not sure how exactly how the ARM arch operates, though. Perhaps this is an 'optimization' bug to save space by not including the ISO-8859-1 - > UTF-8 converter? The simplest solution is to set the default locale to use UTF-8, so no conversions are performed between the system and GTK+ (which uses UTF-8 internally) -- though some things like IRC and Mozilla may break w/o an ISO-8859-1 -> UTF-8 converter. The proper solution is to both set the default locale encoding to UTF-8 and install the proper converter. -- Peace, Jim Cape http://ignore-your.tv "It is literally true that, like Christianity, Socialism has conquered the world by defeating itself." -- Alexander Berkman, ABC of Anarchism signature.asc Description: This is a digitally signed message part

I'm not really informed on whether NULL is ever != 0, but have you tried
terminating the string with NULL instead of "0L"?

Hmm. According to my /usr/lib/gconv/gconv-modules file, cp950 is an alias for big5, try using big5 instead (your iconv may not have that alias set)... -- Peace, Jim Cape http://ignore-your.tv "It is literally true that, like Christianity, Socialism has conquered the world by defeating itself." -- Alexander Berkman, ABC of Anarchism signature.asc Description: This is a digitally signed message part

How to > convert it to utf8? You should call g_convert, with the src_encoding properly set to the same type as the chinese character to convert. Known chinese encodings are: (Simplified): EUC-CN, GBK, GB18030, ISO-2022-CN (Traditional): BIG5, BIG5HKSCS, EUC-TW So, if the character is encoded in BIG5, the proper call is: gchar* dest = g_convert (big5_str, -1, "BIG5", "UTF-8", NULL, NULL, NULL); If the source string is in another encoding, then you can replace "BIG5" with the other encoding's name. (the last 3 arguments are for bytes_read, bytes_written, and an optional error-code/msg return.) -- Peace, Jim Cape http://ignore-your.tv "It is literally true that, like Christianity, Socialism has conquered the world by defeating itself." -- Alexander Berkman, ABC of Anarchism signature.asc Description: This is a digitally signed message part

gdk_window_get_parent assertion failed sometimes.
I had reported this issue on bugzilla, the id is 115432.

Re: Can I make a IM Module resident?
Hi, Sorry to bother you again. Does it mean, if I create an instance of this type within my immodule, then my module will never be unloaded? Because im_module_exit will never be called if there is an instance living, but the instance must be destroyed within im_module_exit.
