Tips for VC using ctooltipctrl

Follow these steps to find information and test the information correctly.

1. Define ctooltipctrl m_tip; in

Bool cxxxdlg: oninitdialog ()

{

...

Enabletooltips (true );
M_tip.create (this );
M_tip.activate (true );
Crect RC; // RC is the Coordinate Position of a region. Note that the coordinates of non-customer regions are generally obtained and need to be converted to those of non-customer regions.
M_tip.addtool (this, "help", & rc, 1); // You can also add a prompt for a control to obtain its cwnd * pointer and region size.

}

2. Reload virtual bool pretranslatemessage (MSG * PMSG) of the DLG );

The implementation is as follows:

Bool cxxxdlg: pretranslatemessage (MSG * PMSG)
{
If (m_tip)
M_tip.relayevent (PMSG );
Return cdialog: pretranslatemessage (PMSG );

}
