An Example of Overlapping Controls (CRgnedButton)

Whenever a developer wants to create overlapping controls for example a Button with inner buttons, or a slider inside it, he faces a problem that whenever a user clicks on the button inner items disappear. I found a simple solution for this problem, which also prevents any distortions in the drawing if the inner controls.

Using this special button control is very simple, just use the ClassWizard to subclass your button to a CRgnedButton class typed control, and start overlapping it with what ever you want. (Of course don't forget to include the header file and cpp file, CRgnedButton.h & CRgnedButton.cpp accordingly)

To manually add a CRgnedButton to your existing Dialog do the following:

Add to your Dialog control the following (after adding a visual Button, using the Visual Editor):

  • To the Dialog's header file:
    #include "RgnButton.h"
  • (under the Dialog class)
    CRgnButton	m_Btn1;
  • To the Dialog's cpp file:
    (under the Dialog DoDataExchange)
    DDX_Control(pDX, IDC_BUTTON1, m_Btn1);
