public procedure TfpgWidget.InvokeHelp; virtual; |
InvokeHelp is called automatically when the user presses the application help key (normally F1) while the widget has the focus. If a help topic is defined for this widget (using HelpContext or HelpKeyword, depending on the value of HelpType), then InvokeHelp displays the topic by calling the KeywordHelp or ContextHelp method of the fpgApplication object. If no help topic is defined, then InvokeHelp attempts to call InvokeHelp for its parent. This allows a container widget to specify a default help topic for its children.
