DoOnHelp is a method called to perform actions needed when the Help command is executed for the task dialog. It signals the OnHelp event handler (when assigned) to respond to the help request.
DoOnHelp is called when the widgetset handles a TDN_HELP task dialog notification message which occurs when the Help button is clicked. For platforms where an emulated task dialog form is used, it is called from the KeyDown method in the TLCLTaskDialog instance when the F1 key is pressed.
Added in LCL version 4.0.
