I can't (personally) see any reason for calling Dialog() on a specific window, but given that MS allow GetMessage() to be called with a specific window handle, there must be cases when people want to do this, and Dialog() is written to allow it. Hence, I wouldn't change it to be forbidden. Perhaps a warning issued if Dialog() is not called statically? Something like: if( PL_dowarn items !=0) warn(You probably meant Win32::GUI::Dialog()\n); near the start of the CODE section? Regards, Rob.

[perl-win32-gui-users] Catching Combobox droplist mouse clicks
From reading this list it seems I'm wasn't the only Win32::GUI user befuddled by droplist style Combobox control not catching mouse clicks and other events. I spent way too much time yesterday RTFM, digging for a solution, and trying to get it to work but finally today stumbled into the solution: If you create a Window and Combobox control like so: $Window = new Win32::GUI::Window( ... options ... ); $Window-AddCombobox( ... options ); ...and if your main window is processing messages like so: $Window-Dialog(); ...then it seems that not all messages (such as mouse clicks) are filtered down to the Combobox control (thus not allowing droplist items to be selected with mouse clicks) unless you change the above statement to this: GUI::Dialog(); ...or I suppose Win32::GUI::Dialog() would work just the same, and presto, now you can mouse click on items in the Combobox droplist. Seems to affect which messages are being passed down to the Combobox control via its parent window. I don't know if this is a Win32::GUI::Combobox bug or what but anyhow hope this hint is useful to other users running into similar issues. -Kurt
Re: [win32gui] [perl-win32-gui-users] Catching Combobox droplist mouse clicks
From the html page for the Win32::GUI class:
Dialog()
Enter the GUI dialog phase: the script halts, the user can interact
with the created
windows and events subroutines are triggered as necessary; note that
this function
must be called without ANY parameter or instantiation (eg. don't call
it as method
of a created object):
Win32::GUI::Dialog(); # correct
$Window-Dialog();# !!!WRONG!!!
Win32::GUI::Dialog(); does a similar thing to
while(Win32::GUI::DoEvents() != -1) {};
see also DoEvents() see also DoModal()
Regards,
Rob.

If you create a Window and Combobox control like so:
$Window = new Win32::GUI::Window( ... options ... );
$Window-AddCombobox( ... options );
...and if your main window is processing messages like so:
$Window-Dialog();
...then it seems that not all messages (such as mouse clicks) are
filtered down to the Combobox control (thus not allowing droplist
items to be selected with mouse clicks) unless you change the above
statement to this:
GUI::Dialog();
...or I suppose Win32::GUI::Dialog() would work just the same, and
presto, now you can mouse click on items in the Combobox droplist.
Seems to affect which messages are being passed down to the Combobox
control via its parent window.
I don't know if this is a Win32::GUI::Combobox bug or what but anyhow
hope this hint is useful to other users running into similar issues.
