Responding To Buttons

When the user clicks a button, the button's parent window receives a notification message.

If the parent window object intercepts the message, it can respond to these events by displaying a dialog box, saving a file, and so on.

To intercept and respond to button messages, define a command response member function for the button. The following example uses ID ID_BUTTON to handle the response to the user clicking the button:

DEFINE_RESPONSE_TABLE1(TTestWindow, TFrameWindow)
 EV_COMMAND(ID_BUTTON, HandleButtonMsg),
END_RESPONSE_TABLE;
 
void TTestWindow::HandleButtonMsg()
{
 // Button was pressed
}
