My program has a GtkDrawingArea in a resizable window. The drawing area needs a 2D array of integers, sized so that there is 1 integer per pixel. When the user moves his mouse over the DrawingArea, I want the program status bar to show the value from the array corresponding to the pixel under the mouse.
I have two questions: 1) I am currently trapping the "configure-event" signal and resizing the array there. Is this the best approach? In my past life, I used to program for the Windows API, I'm basically looking for a replacement for WM_SIZE. 2) I had a bug in my program in which I would occasionally get a mouse cursor position outside the drawing area (for eg: the last time configure-event was called, I got a 400x400 window, but I'd get pixel values of, say, x = 403). I handle these by bounds-checking before I access the array, but why would I get such values in the first place? This is why I wonder if trapping "configure-event" was the right thing to do. Thanks, all. -Jim _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
