You're getting a segfault because GtkButton::clicked signal[1] has
only 2 arguments: a GtkButton and user provided data. Your function
should be defined as:
void
rip (GtkWidget *button,
gpointer source_combo_
I have a callback function which looks like:
void rip( GtkWidget *widget, GdkEvent *event, gpointer
source_combo_box )
{
gtk_combo_box_append_text( source_combo_box, "HHH");
}
And causes a segmentation fault whenever it is called. Why is this? I
thought perhaps I need to cast the source_combo
The following solution does the job though it causes flickering.
- If there is a previous backing store (see below) then restore it to the
underlying image.
- Define the rectangle to draw by the button-press and the
motion-notify-events.
- Copy the four edges of below the rectangle
I gather from recent discussion on the gtk-devel list that a good
deal of the old GDK drawing API may be removed for GTK 3 in favor
of use of cairo: in particular GdkGC seems likely to disappear.
There appear to be good arguments for this, but it means some
extra work for people trying to get their

You mean check at run-time? Using the API provided for that, if any.
For GLib, use the glib_major_version, glib_minor_version and
glib_micro_version variables (which are e

Hi,
I'm wondering how to check the runtime version of the (glib and gtk for
example) DLLs, that the application is linking to.
I know one can check the version of included headers and statically linked
libraries using GLIB_MAJOR_VERSION and glib_major_version, but the dynamic
linking is giving me
