Re: Strange display problem with gtk-win32 and VC++

So if I shorten the label text to 10 characters, I get 10 squares etc. I'm not sure if this mailing list supports file attachments but if there's a way to attach a file, I have a small screenshot available which illustrates the problem. If it works with the official GTK binaries (which is what I assume you meant when you said gnome binaries), I would just stick with those. You don't want to be in the business of supplying GTK binaries. That's a difficult, time-consuming task; just look at all the conversations about the Windows GTK libraries involving Tor - no one ever wants to volunteer to help.

Re: GTK+
The way this is typically done is to check in main() for any already-running processes, and if present just shut down the newly started one. If you want to be user-friendly, you can give focus to the already running version so the user is not left wondering why the app didn't start. One tricky part is that the user may have renamed the executable, so don't hard-code the name of your app inside main. Instead, identify the name under which it was started in main(). To be even more fool-proof (since the user may rename the executable between the first and second invocations), you can create some type of signal (e.g., semaphore) when the first instance of the app is run. Subsequent instances can just look for the presence of that signal. natarajan wrote: Hi all, Is there a way in GTK+ which I can use to stop users from running multiple instances of an application program.

Well, you haven't really told us anything about your app, so we can only provide generic answers. One thing you can do so your GUI elements are repositioned automatically as a containing window grows or shrinks is to put the elements into layout widgets. See, for example, vbox and hbox.

Gtk provides mechanisms for doing this sort of thing appropriately. Take a look at hbox and vbox. These are layout mechanisms.

Did you search archives before posting? I just answered this 5 days ago:

Thanks, I didn't realize there's a popup_menu signal. After trying it,
I find
that the signal popup_menu does not work with the GtkTreeView widget.
I notice the tests/testiconview program use the popup_menu signal
on GtkIconView widget as well, but its popup menu works only by
connecting to the button_press_event signal of GtkIconView widget.
If I comment out the button_press_event signal connection, the program
would fail to popup the menu. It actually rely on the event's position to
determine which icon is chosen.
Ha! You're right and I'm wrong. I wrote this code over a year ago and
obviously I forgot what I did. In order to detect a button press in a
GtkTreeView, do this:
gtk_signal_connect (GTK_OBJECT(widget), button_press_event,
GTK_SIGNAL_FUNC(gtktreeviewbuttonpressed),
(gpointer)UMAKEINT(GetWidID(), cmd));
Don't worry about the last param, that's just the user_data that's
specific to our application.
Here is the code from our app that actually does the popup. This code
comes from the gCvs member of the CvsGui family.
void UCvsPopupMenu::DisplayPopupMenu(void* info)
{
if (menu != UMENU_NULL)
{
GdkEventButton *event = (GdkEventButton *) info;
int button, event_time;
if (event)
{
button = event-button;
event_time = event-time;
// printf(UCvsPopupMenu::DisplayPopupMenu called with event\n);
}
else
{
button = 0;
event_time = gtk_get_current_event_time ();
// printf(UCvsPopupMenu::DisplayPopupMenu called without event\n);
