The application uses a listview and works out current position in it, but the
list does not scroll to it. The user have to do this manually, which is tedious
if the active position is far down the list, say at position 5000.
I am using the following fragment to set the selection at pos:
Try this for screen resolution
void getscreenres ( int * widthret , int * heightret )
{
GdkScreen * screen = gtk_window_get_screen(GTK_WINDOW(window));

The WM_INITDIALOG message is emitted for a dialog when it is safe and possible

you might try this in a different way.

The program has a top window with a menu. The menu is used for functions
directly associated with the top window and for functions associated with

the top window menu contains functions that generate and insert text

Hi Ken,
I am not sure if event-after would be a clean approach.
However , following way for getting notified for any event
I am trying to do a bit of syntax highlighting. I am using
gtk_text_buffer_create_tag and gtk_text_buffer_insert_with_tags to
syntax-highlight the intial text (from file). That works fine.
The program needs to identify existing syntax tokens in order to do appropriate
syntax checking should

Insert dm-clicked = num; before g_signal_connect in the double-nested loop.
