Hello All,
I would like to have a 'Window' pull down menu item on my GUI's menu
bar. In theory, this 'Window' would contain a list of image window
names where the number and names of windows can change while the GUI is
running. This menu is simply a way to show what windows are available
and which is the 'current' window.
The current selection is easy to show using the CHECKED_MENU option to
WIDGET_BUTTON (see http://www.dfanning.com/widget_tips/checkmarks.html)
(I must say, the check mark has an unexpected appearance on my Mac.)
Now, I can add buttons as more windows are opened...
http://www.dfanning.com/widget_tips/dynamic_menus.html
But how the heck to I get rid of an item if its window is closed?
I have tried
WIDGET_CONTROL, thisParticularButton, /Destroy
but it doesn't update the pull down menu. The only way I can get it to
update as I would like is to kill the entire GUI and re-realize it. Yuck.
I had the whole shebang in a list widget, but i was hoping to save real
estate by moving the list to a pull down menu.
Thanks,
Ben
