I think multiple inheritence would cause compiling errors. Maybe you should try checking and removong things like "#pragma interface"

I don't think (if wxDev-Cpp hasn't add it).

thanks
I think your'd better check for something like "#pragma interface" in your code.

Just a quick thought: Does it work when displaying the bitmap after SwapBuffers()? Yes, bitmap showed after SwapBuffers. But my old MFC program are mixed OpenGL with GDI, so bitmap displaying might happen before SwapBuffers. I added a PFD_SUPPORT_GDI flag to wxGLCanvas and made wxMSW version work. ...

How to make Opengl work with gdi?

I added some codes in wx sample "opegl/penguis". I just want to show a little bitmap in the left top corner of GLCanvs, but it didn't work. Is it possible to make opengl work with common gdi? void TestGLCanvas::OnPaint( wxPaintEvent& WXUNUSED(event) ) { // must always be here wxPaintDC dc(this); #if...

unsigned char red, green, blue; bitmap.GetPalette()->GetRGB(paletteIndex, &red, &green, &blue); wxColour colour(red, green, blue); Thanks for post. Maybe I didn't make myself clear. I create a palette like these: wxClientDC dc(this); BYTE r[]={255,0,0} BYTE g[]={0,255,0} BYTE b[]={0,0,255} wxPalett...

In the not-so-close future, and 2.7 is a development series, not (API) stable. This workaround will appear in 2.6.3 too, once its released, which has been planned to be done soon (but the discussion seems to have faded away right now, I'll ping in a couple days probably) Thanks for help! I am a lii...

I sm running into the same problem

I wonder if that isn't the whole backtrace then for some odd reason. With set args --g-fatal-warnings I'm quite sure there should be more. It's hard to help for me without seeing the backtrace or something else informative, as I haven't seen that gtk+ warning myself anywhere in that context, and th...

Re: Changing frame shape

How could I change the shape of the window frame. Window frame by default would be rectangular, how could I make it circular or oval. SetShape() can be used to give polygon shape, but not useful in creating circular shape. Can somebody help me out? The easiest way to achieve this would be using a b...

It won't work. Because wx.h includes windows.h, and MFC doesn't allow windows.h being included before mfc header files.

Thanks for replys. The undef not only undefined the API macro, but also made some MFC classes' member functions can not be used. Like this:

#define TestF TestFA

class A{
void TestF(){};
};

#undef TestF

void main()
{
A a;
a.TestF(); //compiling error: 'TestF' : is not a member of 'A'
}
