A button that looks like a LED.

Sample Image - CLedButton.jpg


class CLedButton : public CButton (version 1.0)

This is a class which displays a LED that has 2 states: ON or OFF. The LED can have some text on its right. The LED is read-only (on user side) and cannot have focus (you should disable "tab stop" in the resource). The disabled state is not implemented: it is exactly like the enable state.

How to use CLedButton:

  1. To your dialog, add either a button, a checkbox or a radio button.
  2. Bind it to a member variable (of type Control) using Class Wizard.
  3. Then change in the header file, the class type to CLedButton.
  4. In InitDialog(), bind your bitmap resource to the button:
    m_greenLed.SetImage( IDB_LEDBUTTON_GREEN, 15 );
    //15 is the width of one image in the bitmap
  5. You can set or retrieve the state of the LED (ON or OFF) using the following member:
    m_greenLed.Depress(TRUE);  //ON  (second image in bitmap)
    m_greenLed.Depress(FALSE); //OFF (first image in bitmap)

The bitmaps are given with the source code:

  • greenButton.bmp
  • redButton.bmp

The sample project was compiled with Visual C++ 6 (MFC 4.2 ) and not tested with Unicode.
