Freezing top level windows

[Paarvai Naai wxWidgets Users]

Hi all,

I would like to switch the mouse cursor to an hourglass and freeze my
GUI from accepting events for about 1-2 seconds. I have found that
using wxEnableTopLevelWindows(FALSE) in MSW works nicely for this.
Keyboard and mouse events are thrown away and the window is otherwise
as-is. On GTK, this function grays all of the widgets as well, which
is redundant since the mouse cursor is already an hourglass. I would
prefer that all of the widgets not be grayed but just unclickable
(somewhat like when a modal dialog is displayed).

What is the quickest, cleanest, cross-platform way to do this with WX?

Please make sure to include wx-***@lists.wxwidgets.org in any reply
as I am not personally subscribed to the wx-dev list.

Thanks in advance!
Paarvai

Unfortunately there is no other way to prevent them from receiving input
under wxGTK right now. I guess we should be able to grab the mouse (which
is what modal dialogs do) and ignore events from it but there is no support
for this currently.

Please don't cross-post to both lists because many people are subscribed
to both of them and getting one copy of a message is quite enough.
