Detecting Right Mouse Double Click

[johncp]

I want my Form to separately recognise left and right double mouse clicks, and the left double click handler to recognise a depressed key so single button mouse users can emulate a right double click.

The Builder mouse dblclk handler uses method TNotifyEvent which provides no event parameters.

How do I use Builder's OnDblClick event handler to find which mouse button and any keys that were pressed ?

or

Windows generates a wm_LBUTTONDBLCLK msg. & a wm_RBUTTONDBLCLK msg.
if the window has the CS_DBLCLKS style (What is this ?)
Do I override the Builder component method for handling the event, with my own method to handle the windows message ?

Yes there are. They were already in bcb5 and maybe before.

void __fastcall TForm1::FormMouseDown(TObject *Sender, TMouseButton Button,
TShiftState Shift, int X, int Y)
{
if ( Shift.Contains ( ssDouble ) )
{
if ( Button == mbLeft ) //do something ;
else if ( Button == mbRight )//do something ;
}
}
