about button_press_signal?

exit(0);
}
The second function can receive button_press_event and the first can
not,why?
The widget that inherit GtkWidget could catch button_press_event,didn't so?
In second function I replaced GtkFixed by GtkBox . Then it can't catch
button_press_event.
Who can explain for me ?
Thank you!

Re: change the colour of widget after it has been shown
I create 2 pixmaps equals and put a gtk_timeout_add to swap these

but...works.
The function that make pixmap swap:

gboolean use_pixmap_interno, GdkPixmap *pixmap_interno)
{
GtkWidget *pixmap;
GdkColormap *colormap;

pixmap = lookup_widget(user_data, nome_pixmap); /* lookup_widget from
support.c from glade */
if(use_pixmap_interno == FALSE)
{
if (!filename || !filename[0])
return -1;
pathname = gnome_pixmap_file (filename);
if (!pathname)
{
g_warning (_(Couldn't find pixmap file: %s), filename);
return -1;
}
colormap = gtk_widget_get_colormap (user_data);
gdkpixmap = gdk_pixmap_colormap_create_from_xpm (NULL, colormap,
mask, NULL, pathname);
if (gdkpixmap == NULL)
{
g_warning (_(Couldn't create pixmap from file: %s), pathname);
g_free (pathname);
return -1;

}
else
{

gdkpixmap = pixmap_interno;
}
if(use_pixmap_interno == FALSE)
{

How to render text to a drawable? (gtk+ 1.3)
Hi everyone, I'd done a bit of programming with gtk+ 1.2 (but not much), and I am working on a new project using gtk 1.3. I have a pixmap that I simply need to render some text to. gdk_draw_text is deprecated, so I assume we are supposed to use pango. I see a pango_x_render, which lets you render to an X drawable, but I don't see any gdk equivalent. I suppose I could fetch the X drawable from gdk but it seems to me the _right_ way to do this shouldn't be that convoluted. I'm convinced I'm missing something. Can anyone help?

That is the right way. One of us is missing some detail.
Its as simple as the following code, where gPIM[0] is a valid and working
GdkBitmap with width pix_w and height pix_h, and h is a gtkdialog.
static GdkBitmap *gPM;
static void create_higher_bitmap(){
/* This should work, but it doesn't */
GdkGC *gc;
gPM=gdk_pixmap_new (h-window,pix_w,pix_h,1);
if (!gPIM){fprintf(stderr,xftree: error 3348\n);return;}
gc = gdk_gc_new (h-window);
gdk_draw_pixmap(gPM,gc,gPIM[0],0,0,0,0,pix_w,pix_h);
gdk_gc_destroy (gc);
return;
}
gdk_pixmap_new does not return NULL.
Maybe I'm screwing up with the gc which should have special considerations
for bitmap working.
Maybe there's something particular with src_private-xwindow or
drawable_private-xwindow:
XCopyArea (drawable_private-xdisplay,
src_private-xwindow,
drawable_private-xwindow,
gc_private-xgc,
xsrc, ysrc,
width, height,
xdest, ydest);

How to set the combo box item
I'm using a combo box in one of my applications. I can set it up fine, and it works ok. I am just wondering if there is a way to set what item is selected? For example, I might want the combo box to automatically select a certain item based input from other widgets. I looked through the docs and header files and I didn't see anything like this. Additionally, I'm a bit confused about what widgets I can directly access in the combo struct. The tutorial says you can use the entry widget: Now, if you want to set the string in the entry section of the combo box, this is done by manipulating the entry widget directly: However, the documentation (http://developer.gnome.org/doc/API/gtk/gtkcombo.html#GTKCOMBO-STRUCT) says you shouldn't change the entry or the list directly Finally, to add to the confusion, the header file says that *only* the entry and the list should modified. Maybe I'm being too picky?

Chris GTK+ Tutorial has scribble.c code that has many subroutines that Chris are tied to events. Chris Many of these are static. Please explain what static gives you Chris in C. In a small standalone application like scribble it doesn't really buy you much, but if you are writing a more significant application, using static to restrict the visibility of functions only used local to the file they are declared in reduces global namespace pollution and thus the chance for conflicts at compile or link time. Just to provide a dumb example, suppose you named an event handler connect. If it's not declared static it will conflict with the standard library function of the same name. -- Skip Montanaro ([EMAIL PROTECTED] - http://www.mojam.com/) ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
