This sample code is not causing me a problem.

In that case it's not very helpful.

Maybe you're making a mistake like the one in this thread:

I don't think it makes sense to store and load the image from HD on each redraw. But storing the bitmap in memory and only update it when the content actually changes definitely makes sense.

What platform, wxWidgets version?

Does it only happen with when the controls are inside a MDIChild?

It might help if you could build a minimal compilable sample that demonstrates the problem.

const char* print_all_cycles(void) { int i,j; string s=""; [...] return s.c_str(); } You can't return strings like this. You're returning the pointer to data in a local variable. At the end of this function, the pointer will be unvalid. At first sight this may work, depending an how and w...

What exactly does "doesn't work" mean? Does your program not start at all or does it just behave differently?

In the latter case: What exactly?

I'm not really an OSX expert, i just remembered that when i wanted to build on OSX once that OpenGL was not enabled ( it said "Opengl support: no" )

But as i didn't need it, i didn't care too much.

You can try adding "--with-opengl" to configure, didn't work for me though.

Check the output of your configure call again if OpenGL was successfully detected. (It's somewhere in the summary at the end). If not, wxGLCanvas will not be available.

Java is definitely not "light-weight" ;) Unless you mean Java-Script. Depending on how much code you need "behind" the controls, running the whole "application" as a webpage in a browser could be an option. But without knowing what your application does it's hard to gue...

whats the equivalent of wxgrid begin batch and endbatch for wxListCtrl?

There is nothing, except the general Freeze() / Thaw()

You could also try wxAuiNotebook, which - as a non-native control - might be more willing to accept non-standard colors

What you're describing is definitely possible with wxWidgets. The question is: What else do you need/will you do in your program? wxWidgets' strength is that is uses native controls. If it's just rectangular shapes that act like buttons, it's ok, but the more custom-looking controls you need, the ha...

In wx 2.8.12 these files were still there. But i haven't read anything about dropping support for DMC, so i guess they were just forgotten in 2.9.3. For a definite answer you may have to ask on the wx-users mailing list, where you can reach the wxWidgets core developers: http://www.wxwidgets.org/sup...

It doesn work as expected in 2.9.2 while the same works good in 2.8.12 well, what do you expect and what happens instead? Besides, wxThread::Yield() has nothing to do with event handling (like wxApp::Yield()). It just gives the rest of the timeslice back to the system for other processes. wxWidgets...

wxThread::Yield() still exists:

If you want one control be "on top" of another control, it must be a child of that control. If two siblings (controls that have the same parent) overlap, the redraw order is more or less undefined, that's why you get the redraw problems. In general, wxWidgets is not too well suited for a d...
