I think it's a bug in wxWidgets, as it can also be seen in the "widgets" sample.

You probably wanted to use "i" instead of "0" in this call.

In wx 2.9.3 WarpPointer does exist even for the Mac port. If you don't want to upgrade, maybe you can include this code into your application directly: From wx/src/osx/window_osx.cpp // Coordinates relative to the window void wxWindowMac::WarpPointer(int x_pos, int y_pos) { #if wxOSX_USE_COCOA_OR_CA...

Another question i have in conjunction with this, how can i find width and height of a character of a fixed-width font at a given font size? There is no dedicated method for this, usually you just use wxDC::GetTextExtent() and pass a single character string. http://docs.wxwidgets.org/stable/wx_wxdc...

Did you try wxBitmapToggleButton?

I haven't read the whole code, but you can't access gui elements (like wxTextCtrl) from secondary threads in wxWidgets. You should use a wxTimer for the gui updates. (And any frequency higher than 60Hz is pretty much useless for that because on current computer screens that's the maximum update rate...

Is there a way to get the used border size for controls that were added previously?

wxSizer::GetItem(), then wxSizerItem::GetBorder()

Which one should i go with?

I think this is something you have to answer for yourself.

It really depends on how long an average redraw takes. If it's more than a few seconds it might make sense to load the bitmap from HD, especially since you already have the code to cache and re-use the bitmap.

SetChar() only works if there is already a character at that position, you can't use it when you start with an empty string.

WM_INPUT messages should not rely on focus, that's why you set the window handle that should receive the message with RegisterRawInputDevices(). Did you use the window handle of your DXCanvas instance there?

I tested your code and made two small changes (marked with "DMX"). This works on Windows (2.9.3rc1) and GTK (2.9.2), but i can't test on OSX. #include "wx/wx.h" class TestApp: public wxApp { private: virtual bool OnInit(); }; class TestFrame : public wxFrame { public: TestFrame()...

I'm pretty sure this function is not meant to check for key combinations.
