How to create rounded wxBitmap buttons?

Question

CustomBitmap *bitmapCtrl1 = new CustomBitmap(mainPanel, bitmap1, id+1, rollover_bitmap1, NULL, wxDefaultPosition, wxSize(125, 125));

CustomBitmap class is derived from wxControl. And this is my OnPaint function.

void CustomBitmap::OnPaint(wxPaintEvent& WXUNUSED(event))
{
    wxPaintDC dc((wxWindow *) this);
    SetTransparent(0);
    
    if (m_enter)
    {
        dc.DrawBitmap(m_bmpmouseover, 0, 0, true);
    }
    else
    {
        if (m_leftdown || m_rightdown){
            dc.DrawBitmap(m_bmpclick, 0, 0, true);
        }
        else {
            dc.DrawBitmap(m_bmpstatic, 0, 0, true); 
        }
    }
#ifdef WX3 
    //dc.EndDrawing();
#else
    // dc.EndDrawing();
#endif
}

Generally speaking, you can't customize drawing of the native controls, they just are not made to cooperate with you. If you need round buttons, you will have to draw them and also handle input and generate events for them entirely yourself.

You may find wxRendererNative and wxMouseEventsManager helpful for drawing and input handling respectively.
