Hey folks!
OK, huff, I hit a wall people. I just can't get this program to display the ComboBox within an acceptable size!
I can manipulate the width of the widget, but getting the height to a more suitable size has proven to be a real challenge.
Below is the code for the program and if you have to look at the window I can send you a 'GNP' file that will show you what I mean.
Please note that I am using the Win32 version of Gtkmm and that many times I have had gone a great length to fix a problem, just to realize that the problem lies within the Win32 port of the toolkit.
Thanks in advance.
