invalid utf-8 string pango warning
Hello gurus, I am a novice(both in C and in gtk+), but managed to create a parser that will create a tree from the parser. The problem is, in the minimal example posted in fpaste, if the line 264-266 is uncommented, i.e. I parse the same file twice, I get Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text() This reading the same file twice matches the exact behavior when I open and parse the file using filename=gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(dialog)); g_file_set_contents(filename, buffer, -1, Err); The code, sample example and makefile is at: http://paste.fedoraproject.org/13915/04195136/ http://paste.fedoraproject.org/13917/04584136/ http://paste.fedoraproject.org/13918/13693046/ Any help on where I am going wrong will be appreciated. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
better practice for work with saved buffer
hello friends, I am working on a gtk_list_store, that will save the rows to a file (set_contents(file, buffer)) After saving the datas to a file, without exiting, I will like to edit the file (as buffer) again. For that I have 2 option in my knowledge: 1) save the data, g_free(buffer), list_store_clear, reload the saved file 2) save the buffer to the file, but continue working with that without g_free(buffer) both seems to work, but which is the better practice? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

parsing bibtex using gscanner
Dear Friends,
I am trying to parse a bibtex file using gscanner.
The problem is that, due to many formats accepted by bibtex, it seems
bit hard to parse it.
What I mean is as long as the bibtex is of the form key=some value,
then g_scanner_get_next_token can get the string.
But it fails if it is in the format key={value}.
I am attaching my code. Some help (outside using btparse/ bison )is
needed.

GHashTable *table)

int tokount;
/* Entry starts with @ */
g_scanner_get_next_token (scanner);

my final goal is to able to edit the file, but not save every time

So, in irc and other place, i was instructed to use get_contents method.

In C, there is an api that allows us to open a file, and then associate a

file, automatically shows in the buffer (i.e. no read() or re-read is
required) and any modification to the file buffer will automatically show on
disk (without the necessity of a write()).
Is this what you are trying to do ?
If yes, then the below will not accomplish this. The C api is to do a standard
open(2) and then a mmap(2) to associate the file's buffer to a fixed memory
location - I am happy to supply more details upon a confirmation.
All the best,
-Greg

writing to a buffer: help
Dear friends,
Please have a look at http://fpaste.org/gvF3/
So, I am writing those values to a string and then to a file(for now!)
given that, Entries e are a structure, as,
typedef struct {
GtkWidget *combo, *entry1, *entryAuth, *entryEditor, *entryTitle,
*entryPub, *entryVol, *entryIss, *entryPage, *entryMon,
*entryNote, *entryKey, *entryYear, *entryAdd, *entryEdition,
*entryJournal, *entrySeries, *entryBooktitle, *entryOrg,
*entryChap, *entrySchool;
} Entries;
is there a better way of writing this; considering the fact that I have
to check if any of the entry is NULL?
My second question in this is that,
I have created a buffer from a file in a different function as
char* buffer;
gsize length;
GError* error=NULL;
filename = gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(dialog));
g_file_get_contents(filename, buffer, length , error);
I have not g_free-d it. Can I use the same buffer to if I want to
append the buffer from update_file.c? Or should I g_free that buffer and
reopen it?

open an existing file in buffer and write on it
Dear friends,
as evident from my last few posts, I am struggling with opening a file
as buffer and write to it
(guess it has *nothing* to do with gtk, but C. Still I will be grateful
if you people kindly help).
So, first, how to open file in buffer?
/* Files opened and edited directly*/
/* FILE *fop = fopen(filename, a );
if (!fop){
filename=Untitled.bib;
fop= fopen(filename,a);
}
*/
/*Trying to open file as buffer and edit that*/
FILE *fopf = fopen(filename, a );
if (!fopf){
filename=Untitled.bib;
fopf= fopen(filename,a);
}
char fop[]=Hello World;
int buf_size= strlen(fop)+1;
fwrite(fop,buf_size,1,fopf);
if(!fop){
printf(failed);
}
fclose(fopf);
gtk_label_set_text(GTK_LABEL(flabel), filename);
printf( fop, @%s{%s,\n, strcombo, strkey );

printf( fop, \tEditor=\%s\,\n, strEditor);
if( strlen(strTitle)!=0)
printf( fop, \tTitle=\%s\,\n, strTitle);
// fclose(fop);
The very first part of the code (commented) used to access the file
directly, an approach that I was advised against. So I tried to open the
file in buffer. But this implementation makes the program crash as soon
as enter some value.
Please help

Re: open an existing file in buffer and write on it
ZZ,
thanks for your comment!
But is it so tough? database and all that?

Since directly editing the file is not recommended, this is the reason
why I want to open it as buffer!

You have to open, read (and then close) the file into a static or malloced
buffer of sufficient size,
then you can operate on the buffer. When your are done you write out the
buffer
to a newfile, delete the old and rename the new to old.
char fop[]=Hello World;
int buf_size= strlen(fop)+1;
fwrite(fop,buf_size,1,fopf);
if(!fop){
printf(failed);
}
fclose(fopf);

PS.: at the first glance it seems to me you need a database backend
like sqlite to save, store, change and retrieve your data.

Re: open an existing file in buffer and write on it
Hi Damien,
Thanks for your reply.
What I have ended up with is something like:
FILE *fopf = fopen(filename, a );
if (!fopf){
filename=Untitled.bib;
fopf= fopen(filename,a);
}
char buffer[]=Hello World;
int buf_size= strlen(buffer)+1;
fwrite(buffer,buf_size,1,fopf);
if(!buffer){
printf(failed);
}
// fclose(fopf);
GString *fop=g_string_new(NULL);
g_string_append_printf( fop,buffer);
gtk_label_set_text(GTK_LABEL(flabel), filename);
g_string_append_printf( fop, @%s{%s,\n, strcombo, strkey );
if( strlen(strAuth)!=0)
g_string_append_printf( fop, \tAuthor=\%s\,\n, strAuth);
if( strlen(strEditor)!=0)
g_string_append_printf( fop, \tEditor=\%s\,\n, strEditor);
if( strlen(strSchool)!=0)
g_string_append_printf( fop, \tSchool=\%s\,\n, strSchool);
g_string_append_printf( fop, }\n);
// fclose(fop);
g_file_set_contents(filename,
fop,
1026,
NULL);
}
But this writes the data in unformatted form.
Can you kindly explain a bit more?

For managing several bibliography files, that should be better yes.

Since directly editing the file is not recommended, this is the reason

For just handling one file, that's not necessary of course.
The idea when you want to change a file on disk is (not too big) :
- generate a buffer of the full content of the file in memory, using
GString for instance
(http://developer.gnome.org/glib/unstable/glib-Strings.html) since
they are automatically expending in size but can be used with
equivalent printf() convenient functions ;
- copy atomicaly the buffer in the file with g-file-set-contents()
http://developer.gnome.org/glib/unstable/glib-File-Utilities.html#g-file-set-contents
- delete the buffer.
Damien.

css for button color
Dear friends, I have a periodic table application written in gtk2 (http://download.savannah.gnu.org/releases/ptbl/). I wrote it in gtk2 because gnome3.4 with default gtk+ theme Adwaita do not show colors of button for gtk3 app. Now, from gnome 3.6, this behavior is applied in gtk2 apps as well. I discussed this issue previously, with the suggestion that overriding theme is actually a bad idea, agreed. But for a app like periodic table, it is basic necessity. So, I, as suggested before, need to use css for the button colors. Can anybody kindly help me with creating css? Is gtkcssprovider usable in gtk2 as well? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

save as file submenu query
Dear friends,
In my project, I have created a SAVE AS file submenu.
I have two question:
1) This save as does not have any key board shortcut(Ctrl+S as
standard) like open or new file submenu, which are also created in the
same way, using accel group. Why this is so?
2) Though the file copying is working fine, I would love to receive some
comment about if this is a dependable(in sense of failsafe and fast)
process of copying file.
The code is as follows:
//In Main
accel_group = gtk_accel_group_new();
gtk_window_add_accel_group(GTK_WINDOW(window), accel_group);
save = gtk_image_menu_item_new_from_stock(GTK_STOCK_SAVE_AS,
accel_group);
gtk_menu_shell_append(GTK_MENU_SHELL(filemenu), save);
g_signal_connect(G_OBJECT(save), activate,
G_CALLBACK(rename_file), NULL);
//the called function

understanding GtkRGBA
Dear friends,
though this might be Fedora(or gnome shell theme Adwaita) specific
problem, I cannot get color from:
GdkColor colorRed2 = {0x, 65535, 29555, 24158};
gtk_widget_modify_bg(button, GTK_STATE_NORMAL, colorRed2);
So, I am trying to use:
gtk_widget_override_background_color (Hbutton, GTK_STATE_NORMAL,
GdkRGBA(0,0,0,1.));
ofcourse, this is not the way to use RGBA.
What is the correct way of using it?

improvements in gtktreeview
Dear friends,
below I have copied the way I am creating a treeview. Maybe, you may
find some part is not necessary, but still I put them to show you how I
am doing the things.
I need help in few things:
1) for my typical testing file, which has ~150 entry(to be parsed by
parse.sh, create file fauth.dat and then read by fauth) It takes
around 5 second! I am afraid what will happen for a bigger file. I tried
to create a parser in C that will directly store the entries of
fauth.dat in array, but failed(Any help in this will be hugely
welcome).
Is there anyway to sppedup the process ?
2) Entries in COL_BIB_NAME can be arbitraryly long(I have set up max
length to 500). Problem is in my present settings, the full line is
written in a single line. Can I set the width of each sell fixed? So,
that when the entry is more then the width, they will break up in
several line? In other word, currently, my cells have fixed hight,
variable width. can I change it to variable hight, fixed width?
3) These two is my matter of concern. But being a novice, I am looking
for any other advice as well.

path for icon
Dear friends, in my GTK(3) app, I am using icons as gtk_window_set_icon(GTK_WINDOW(window), create_pixbuf(images/icon.svg)); or GtkWidget *ast4im = gtk_image_new_from_file (images/mkb3.png); The problem is, when I am running the app away from the source directory, those images are broken, obviously due to the fact that the path is missing. One solution is to put absolute path, but then the code will not be portable. Is there any better way of doing it? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

button background color in gtk3
Friends,
I am putting gtkbuttons inside a grid with modify_bg. I am getting an
odd case that when the window is focused, all buttons are showing white,
not what suggested by modify_bg. The same structure was working fine in
gtk2 (while I was using table instead of grid).
I am posting the complete minimal code(60 line only) for your reference.
I have seen that the gtk_widget_modify_bg is deprecated in gtk 3 so I
tried the suggested method with gtk_widget_override_background_color but
there it seems that declaration of GdkColor colorRed2 = {0x, 65535,
29555, 24158} has changed to something like GdkRGBA.
I tried to change to
GdkRGBA colorRed = {1,0,0,1};
yeilding error:
‘const struct GdkRGBA *’ but argument is of type ‘GdkRGBA’
Please Help.

What do you need to know? Do you want your textview to update as the
file changes?
If your program is appending to the file as well as displaying in the
textview, it would be much simpler just to append to the textview
itself.

auto refresh file in textview
Dear friends,
I am openning an existing file in textview from command line as:
textview = gtk_text_view_new();
gtk_container_add(GTK_CONTAINER(scrolledwindow), textview);
textbuffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(textview));
if (argc 1 argv[1] != NULL) {
char *flnm = argv[1];
read_view(flnm);
}
where the read_view is defined as:
static void read_view(char *inpfn) {
char *buffer;
stat(inpfn, filestat);
textbuffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(textview));
buffer = (char *) malloc(filestat.st_size * sizeof (char));
efile = fopen(inpfn, r);
fread(buffer, filestat.st_size, 1, efile);
gtk_text_buffer_set_text(textbuffer, buffer, filestat.st_size);
free(buffer);
}
I am writing in the file that is opened as:
FILE *fop = fopen(filename, a );
g_fprintf( fop, @%s{%s,\n, strcombo, strkey );
where the fileopen is difined globally.
whenever I am writing, it is saved, but to see the change, I have to
reopen the file(obviously). I checked a post in gtkforums but cant
manage much (http://www.gtkforums.com/viewtopic.php?f=3t=11443) . I
also tried the gtk manual on GFileMonitor and failed.
May I request your time for kind help?

Re: write to a file using g_print
Thanks! Its working excellent.
Now, I have another small problem.
I have opened a file from the menubar filechooser dialog as:
static void open_file(GtkWidget *widget, gpointer data) {
GtkWidget *dialog;//, *entry;
dialog = gtk_file_chooser_dialog_new(Open File,
GTK_WINDOW(window),
GTK_FILE_CHOOSER_ACTION_OPEN,
GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT,
NULL);
if (gtk_dialog_run(GTK_DIALOG(dialog)) == GTK_RESPONSE_ACCEPT) {
char *filename;
filename =
gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(dialog));
read_view(filename);
g_print(filename);
}
gtk_widget_destroy(dialog);
}
I would like to append this file from another function:
static void
activate_func(GtkWidget *widget, gpointer data) {
/* OTHER STAFF */
FILE *fop = fopen(file.bib, a );
g_fprintf( fop, @%s{%s,\n, strcombo, strkey );
/*ETC*/
}
instead of fopen(file.bib,a), I tried fopen(open_file( *widget,
data,filename),a) and also adjusted the argument of open_file.
but its not working.
How I can transfer the filename from open_file to activate_func?

You got this because g_open() returning a int (file descriptor) not a
FILE pointer.
You must distinguish each I/O method that you are using and don't mess with
it.
You can't use a file descriptor to standard libc's I/O functions, use
FILE pointer instead.
#include glib.h
#include glib/gstdio.h
#include stdio.h
FILE *fop = open(bib2.bib, w);
/* you can call g_fprintf() or fprintf() */
see man 3 printf
Is it possible to write to a file using g_print?
g_print() already write to standard output FILE, but you can dup()
standard output to another file.

Re: multiple GTKentry inside a GTKnotebook
Mariano,
Thanks for your help. But this is not what I am looking for.
What I want is I will choose the combobox entry and fill up the entry
box data manually. Then if I click ok button, it will append an
external file with those data.
Please see the quoted reply I made in this thread to your previous
reply.
Hope, I have cleared my intention.
By this code, what I want to achieve is that:
After choosing book/loco/lardon etc as done by you, this will print the
active_data in combobox and Entries in a file.
So, if the combo entry is Book and
entryAuth is MyAuthor
entryEditor is MyEditor
entryTitle is MyTitle
and
bibkey is Mybib
then according to file selected(new/old) it will write there
@book{MyBib
Author=MyAuthor
Title=MyTitle
}
ofcourse the formatting can be done later. My current problem in hand is
to get those text like Book, MyAuthor, Mybib etc as a variable to use.
I googled and found some example but not working.
Last but not the least, thanks Mariano for exporting it to GTK3. its
really looks nice.

Re: multiple GTKentry inside a GTKnotebook
By this code, what I want to achieve is that:
After choosing book/loco/lardon etc as done by you, this will print the
active_data in combobox and Entries in a file.
So, if the combo entry is Book and
entryAuth is MyAuthor
entryEditor is MyEditor
entryTitle is MyTitle
and
bibkey is Mybib
then according to file selected(new/old) it will write there
@book{MyBib
Author=MyAuthor
Title=MyTitle
}
ofcourse the formatting can be done later. My current problem in hand is
to get those text like Book, MyAuthor, Mybib etc as a variable to use.
I googled and found some example but not working.
Last but not the least, thanks Mariano for exporting it to GTK3. its
really looks nice.

Thanks for your interest.
Pasted just below is the complete code.
What I want to do with that is, as a raw commented

106-116 that according to my selection of

But, for that, I need to get the data from the combo

Please help.

So after the combo box, I added the line: gchar *bibtype = gtk_combo_box_get_active_text(GTK_COMBO_BOX(widget)); fprintf(stdout, %s, bibtype); So, that part looks like combo = gtk_combo_box_new_text(); gtk_combo_box_append_text(GTK_COMBO_BOX(combo), Book); gtk_combo_box_append_text(GTK_COMBO_BOX(combo), Article); gtk_box_pack_start(GTK_BOX(vbox), combo, TRUE, TRUE, 0); gtk_widget_show(combo); gchar *bibtype = gtk_combo_box_get_active_text (GTK_COMBO_BOX(widget)); fprintf(stdout, %s, bibtype); which is giving error.

Re: xml parse
Thanks Emmanuel and xiaohu I am new to GTK and C programming. Hence don't know things. Both of your reply helped me to find things out. Google said libxml2 is the standard way, where markup is not so standard to parse xml. I think I will stick to libxml2.

gtk-app to search google scholar
Dear friends, I am trying to make a gtk application that will create a bibtex. The problem is I am a novice in C/gtk programming(this will be only my 2nd programme in gtk). To do that, First and foremost, I need to search google scholar from the code. I tried using lynx and failed. Can anyone kindly show me a simple code in C that can fetch data from google scholar with Import into bibtex entry on?

Re: probable gtk_window_present and pango help
David,
Thanks for your suggestions and the sample code.
I have managed to make it work.
Just one more problem. If I have more then one button, say, in a nxn, it
seems that if one callback is open, I have to close it to open a new one
i.e. only one callback window will open at a time.
One easy solution that I got is to declare nxn child_window, like
GtkWidget *child_window1 = NULL;
GtkWidget *child_window2 = NULL;
and put an unique child_window to each button like
button = gtk_button_new_with_label(main);
g_signal_connect(button, clicked,
G_CALLBACK(callback_it1), child_window1);
gtk_table_attach_defaults(GTK_TABLE(table), button, 0, 1, 0, 1);
gtk_widget_modify_bg( button, GTK_STATE_NORMAL, colorBlue );
button = gtk_button_new_with_label(main2);
g_signal_connect(button, clicked,
G_CALLBACK(callback_it2), child_window2);
gtk_table_attach_defaults(GTK_TABLE(table), button, 1, 2, 0, 1);
gtk_widget_modify_bg( button, GTK_STATE_NORMAL, colorBlue );
when this is very easy, but tedious and (IMHO) NOT the correct way of
doing this thing.
Can you please show how to get this done?

Unfortunately, you are facing much more problems.
For start
gtk_container_add(GTK_CONTAINER(window1), vbox1);
is called with an unitialised variable window1 (i.e. no window1 is ever
created). This leads to a CRITICAL message to console and/or crash.
And if window1 existed then vbox1 would be packed into two different
containers (window1 and window) which is not possible. So I'm ignoring
that part altogether.
The callback should look like
void
callback_it(GtkWidget *button, gpointer user_data)
{
...
}
where in user_data the callback receives the last argument you passed to
g_signal_connect(). It is rarely useful to pass a constant such as
Call there.
The callback is *not* another main() function; it should *not* call
gtk_init() again, etc. Please read the signals section in the Gtk+
tutorial
http://developer.gnome.org/gtk-tutorial/2.90/x159.html
There are several other highly suspicious things:
- redeclaration of global variables (such as window) inside a function;
are you aware this creates a new local variable window that has nothing
to do with the global one?
- inclusion of .c files instead of separate compilation + linking them
together
- calling gtk_widget_show() on individual widgets and then again showing
everything using gtk_widget_show_all()
- not terminating the Gtk+ main loop when the main window is destroyed;
this is usually the first thing to set up in a Gtk+ program, see
http://developer.gnome.org/gtk-tutorial/2.90/c39.html#SEC-HELLOWORLD
etc.
1) The problem is evry time I click the button main, a new window
appears(obviously). What I want to achive is, if the window is already
present, it should not open again; rather it should focus that window. I
believe, this can be achived by gtk_window_present(may be I am wrong).
But I don't know how to use it.
You use it just by calling gtk_window_present() on the window object.
To that meaningfully you need not only to keep the window object around
but also get notified when the window is destroyed. Either by
connecting to the destroy signal or, if you just want to set a pointer
to NULL once it is gone, by using g_object_add_weak_pointer().
2) In the callback function, I have C_1 and C_2. What I want to achive
is Csub1/sub etc via pango(or any other).
For simple things you can sometimes just use UTF-8. But generally, you
need to use Pango markup. If the widget does not have function to set
the markup it has a function to obtain the label widget so that you can
use gtk_label_set_markup() on that.
See the attached code with main problems fixed (and merged to one file).
Please go through the Gtk+ tutorial farther that you perhaps have done.

GTK newbie help on G_CALLBACK
Dear Friends, I have taken a project (my own, not homework) to develop a table. I generally work with fortran, don't know C that much. What I want is a gtk clist to pop up when I press a button, via callback. The button widget in my code is /* Create first button */ button = gtk_button_new_with_label (B1); /* When the button is clicked, we call the callback function * with a pointer to button 1 as its argument */ g_signal_connect (button, clicked, G_CALLBACK (callback), (gpointer) B1); /* Insert button 1 into the upper left quadrant of the table */ gtk_table_attach_defaults (GTK_TABLE (table), button, 0, 1, 0, 1); gtk_widget_show (button); The definations are mostly based on http://developer.gnome.org/gtk-tutorial/2.24/x344.html What I want to do is callback to execute another gtk file, rather than what shown in the example. The source code of the pop up gtk file is: http://www.gtk.org/tutorial1.2/gtk_tut.html#toc11.10 Please help me. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
