Re: displaying 2 images from combobox
when i use this:
{
GtkWidget *image = lookup_widget(GTK_WIDGET(combobox),
img_objectdesign);
gtk_image_set_from_file (GTK_IMAGE(image), Pictures/baby.jpg);
}
it works...as you can see image is already declared in the first line. that
is GtkWidget *image=lookup...etc.
if i declare it at top like GtkWidget *image; there is an error saying
redefinition...so this doesnt solve the poblem..plz help

Re: trying to launch a dialog from outside the main gui thread by emiting a signal to the thread.
On 3/7/07, Kevin Lambert [EMAIL PROTECTED] wrote: I ended up modifying my class such that the information for the dialog gets added to a vector and I added a timer which looks at the vector and if there is something new to be displayed it pops it off and launches the appropriate dialog, thus keeping everything happening within the GUI thread (or at least that is what I am assuming is happening now that the code works). Kevin GLib already has GAsyncQueue for this. Usually, you can get away with using g_idle_add, it's simpler. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

hi...am new to gtk+ and i want to display 2 images in 2 different image
widgets when a specific item is clicked from a comboboxi`ve managed to
display only one picture but i still dont know how to display a selected
item...the image is displayed by default when i use the following code:
void
on_cbo_itemdesign_changed (GtkComboBox *combobox,
gpointer user_data)
{
GtkWidget *image;
image = lookup_widget(GTK_WIDGET(combobox), img_objectdesign);
gtk_image_set_from_file (GTK_IMAGE(image), Pictures/baby.jpg);
}
now i want to assign the image (baby.jpg) to one of the items from the
combobox...but i dont know how to do that...if anyone can help me plz??
secondly i tried to display another image from the same signal but i dont
know how to do it as well...i`ve tried the following code but nothing is
displayed:
void
on_cbo_itemdesign_changed (GtkComboBox *combobox,
gpointer user_data)
{
GtkWidget *image1;
GtkWidget *image;
//for first image
image = lookup_widget(GTK_WIDGET(combobox), img_objectdesign);
gtk_image_set_from_file (GTK_IMAGE(image), Pictures/baby.jpg);
//for second image
image1 = lookup_widget(GTK_WIDGET(combobox), img_patterndesign);
gtk_image_set_from_file(GTK_IMAGE(image1), Pictures/myPattern.gif);

Re: Problem to open a new window using libglade
Hello,
if I use g_idle_add, then when the function from g_idle_add is
executed, it blocks the 'update_pbar' function.
So I probably must make it with threads but by now I think it's to
early for me to work with threads. It's easier if I add the
progressbar into the main window, and update it with:
while (gtk_events_pending())
gtk_main_iteration();
Later I would probably try it with threads.
Thanks for the help.

Great! Thank you very much, this works.
But how can I make something during gtk_dialog_run?
I'd like to do somthing like this.
g_timeout_add(1000, update_pbar, dialog);

...my process which progressbar should show
g_spawn...
progress = 0.2
other work
gtk_widget_destroy(dialog);
dialog = NULL;
update_pbar (gpointer dialog)
{
...
gtk_progress_bar_set_fraction(GTK_PROGRESS_BAR(probar), progress);
...
}
Well,
you either need another scheduled function (prolly g_idle_add) or start
a separate thread when entering your callback and join it before ending.
You prolly want to avoid multi-threading for such a rather limited
use-case.
Also, I've noted a flaw in my pseudo-code around setting dialog to NULL
which does not change the pointer that has already been passed to
update_pbar ... a static global would prolly do here or smth. similar.
HTH,
Karl.

Expose event crashes app
Hi all, I am developing a application, which is able to play back several jpeg/mpeg files simultaneously in a single window(like NxN cell table), I mainly use gdk_draw_rgb_image to render decoded frame. It works quite well for a while but fails to stand for more then 2 week. It will crash with segv after long run(eg, 2 weeks or more). The back trace always looks the the same, and it seems that it has nothing to do with my code, so that I have no idea where to start the investigation. The app is built on gtk+- 2.4.0(fedora core 2 gtk2-2.4.0-1.i386.rpm). According to the bt msg, segv happens when expose event is triggered. I have searched through the mail archive without finding any similar situation. First I'd like to know that whether this is due to the old gtk-2 library. If it is not, where is the good start point for investigation. Any clue is appreciated. #0 0xb7c22a9a in g_object_remove_weak_pointer (object=0x8f74780, weak_pointer_location=0x8f53448 ) at gobject.c:1548 #1 0xb7d02d61 in queue_item_free (item=0x8f53448) at gdkgeometry-x11.c :914 #2 0xb7d030a5 in _gdk_window_process_expose (window=0x9146260, serial=88452651, area=0x20) at gdkgeometry-x11.c:1051 #3 0xb7cfcb9d in gdk_event_translate (display=0x82d7010, event=0x8e484f0, xevent=0xbfffe340, return_exposes=0) at gdkevents-x11.c:1484 #4 0xb7cfd6fd in _gdk_events_queue (display=0x82d7010) at gdkevents-x11.c :2067 #5 0xb7cfd891 in gdk_event_dispatch (source=0x20, callback=0, user_data=0x0) at gdkevents-x11.c:2127 #6 0xb7bb2e4a in g_main_dispatch (context=0x82e1d38) at gmain.c:1895 #7 0xb7bb3f28 in g_main_context_dispatch (context=0x82e1d38) at gmain.c :2441 #8 0xb7bb4260 in g_main_context_iterate (context=0x82e1d38, block=1, dispatch=1, self=0x830fa10) at gmain.c:2522 #9 0xb7bb48a3 in g_main_loop_run (loop=0x8e49790) at gmain.c:2726 #10 0xb7e39403 in gtk_main () at gtkmain.c:1172 #11 0x0809f138 in main (argc=1, argv=0xbfffe664) at main.cc:252 ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Fixing size of window containing 2 buttons
I am just starting with GTK, so no doubt I am missing something basic. I have a window with a buttonbox with 2 buttons. I use size_allocate on the buttons to position them. One of the buttons starts hidden. I would like to size the window so that it will accommodate both buttons, but I keep getting a window wide enough only for the one visible button. I have tried set_size_request on the window. I tried catching size-request on the window to confirm that the requisition is correct. It is. I also have set_size_request on the buttonbox, which I believe should not be necessary (and seems to do nothing). What am I missing? -- Jeffrey Barish ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

It's surely making life more difficult. Why not make the not yet button disabled (gtk_widget_set_sensitive()) until it becomes relevant?
