and if it is possible to change the status
bar text when the user moves the mouse cursor through the menus?
The win32-gui-demos script, distributed with 1.04 and higher has a way
to do this (it's a bit of a hack though).
Where can I find that win32-gui-demos script?
I have taken a look in the demos directory, but I couldn't find something
helpful. Should I look elsewhere?
It's the demo launcher program distributed with Win32::GUI 1.04 and
higher. You should find it in C:\Perl\bin (or perhaps
C:\Perl\site\bin\), adjusting paths as necessary for your perl
installation. If not, then you can find it here:
http://perl-win32-gui.cvs.sourceforge.net/perl-win32-gui/Win32-GUI/scripts/win32-gui-demos.pl?revision=1.5&view=markup
I have also seen that after changing the checked/unchecked state of a menu
item $Win->InvalidateRect(1) is used.
Can you tell me why? If somebody will change the state of a menu item, the
menu closes, and the next time it is opened I think it should appear
changed. Isn't this true?
The InvalidateRect() call has nothing to do with the menu checked state
- it's asking windows to post a WM_PAINT message to the window, as (in
this example) you've just changed the drawing mode, and want the main
window to be completely re-drawn.
I have also seen that there is the method DrawMenuBar() which should redraw
the menu bar only. Shouldn't it be use instead of InvalidateRect() just for
redrawing the menu bar if it is necessary?
Correct, but that's not what's being asked for here.
