How to prevent gui flash after closing a dialog window?

Hi,

On my program, all the mdi child windows flashes after I close a popup option window. But for the "About ..." menu, I use a wxMessageDialog, I found the mdi childs don't flash if I close the message dialog.

What shall I do to prevent the mdi childs from the unwilling flash?

Regards,
-Bruce

Bugs with wxSpinCtrlDouble & wxRadioButton

Make a MDIChild and put a wxSpinCtrlDouble and a button to enable/disable it. 2. New the MDIChild and at this time wxSpinCtrlDouble works fine. 3. Hide the MDIChild and...

Re: wxSpinCtrlDouble can't get focus after hide

I debug the spinctrlg.cpp on MSW and found the reason. The method to modify it is quite simple: bool wxSpinCtrlGenericBase::Show(bool show) { if ( !wxControl::Show(show) ) return false; // Add the following line to fix the problem wxControl::Enable(false); // don't use non virtual Disable() here! //...

Re: Please help with GUI crash problem?

Thanks a lot, I will first do the queue thread and then check the wxString usage. I think I should recompile wxWidgets using the std:string with Visual Studio. Is it the 17th chapter (Writing Multithreaded Applications) of the GUI Programming with WxWidgets book? I will check it up and then do my co...
