I build wxwidgets 2.9.2 on Windows 7 32bit with visual studio 2010.
I turned on unicode and static lib.

My program config is also unicode charset.

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?

Hi, all, I think there are two bugs in wxWidgets. The first one is about wxSpinCtrlDouble: The reproduce procedure is as follow: 1. 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...

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! //...

Hi all, I have a wxSpinCtrlDouble ctrl on the panel. The user controls the hide/show state of the panel. There is a wxSpinCtrlDouble for input price.

Hi, I want to add a toggle state wxAuiToolBarItem on the wxAuiToolBar. I set two wxBitmap images for enable/disable states in order to display different images.

Hi, all, I am not quite sure about the gui thread structure. If I create a application using wxMDIParentFrame/wxMDIChildFrame. There will my several kinds of child window and the user may create a lot of child windows on the frame, each child frame has button/controls to interact with user. 1. My fi...

Thanks a lot, it really wxString::Format caused the problem.

Thanks a lot.

And to make my life easier, I'd better try the unicode version:-)

Hi, all, I am migrating wxWidgets from 2.8.10 to 2.9.2, I uet wxUSE_UNICODE==0 (It's hard to migrate the legacy code from ANSI to UNICODE), but I got a compile error from wxFormatStringSpecifierNonPodType as follows (Now it is the only error left). Is anyone met the same problem before and how to de...

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...

I tried to convert it to wxString, but still crash:-(

Hi, all, I had a program (written in wxWidgets 2.8.10) which is occasionally crashed. I debugged into the program and found that it mainly crash on wxGrid updating. I don't have much experience on GUI coding; I doubt I may have used wxWidgets in the wrong way. I will try to explain clearly the main ...

Hi ,all, I would very much appreciate your help regarding the following issue. I'm building an application that among other things displays live prices and compute profits for a number of financial instruments in a Grid. I noticed that the application crashes when the price changes are frequent (I c...

Hi all, I have a weired problem with wxButton as follows: A "stop" button (wxButton) is set to disabled by Enable(false) when there are unfinished tasks after user click it. When all tasks finished, the button is set to be enabled by Enable(true). Because the tasks and the user click may asynchorniz...
