Project: Message Dialogue Components.
Unit: PJMessageDialog.
Class: TPJWinMsgDlg
Applies to: ~>3.0
property OnHelp: TNotifyEvent;
The OnHelp event is triggered when the user requests help in a dialogue either by clicking a help button or by pressing F1. If OnHelp is handled then the component’s default help processing is inhibited - the event handler must display the required help.
This event is never triggered if the dialogue box does not display a help button. F1 keypresses are ignored when there is no help button.
Handle this event if you want to use an alternative help system to that registered with the Application object.
