TCustomTaskDialog.InternalSetDialogHandle

Sets the value for the Handle property.

Declaration

Source position: dialogs.pp line 792

protected procedure TCustomTaskDialog.InternalSetDialogHandle(

  AHandle: THandle

);

Arguments

AHandle

  

New value for the Handle property.

Description

InternalSetDialogHandle is called when the form instance for the dialog is created. For platforms using a native task dialog (Windows Vista or later), it is called from the callback routine in the widgetset when the TDN_DIALOG_CONSTRUCTED is handled for the widget. For platforms using an emulated task dialog, it is called when the TLCLTaskDialog instance executes the AfterConstruction method in the form instance. It updates the value in Handle before the OnDialogConstructed event is signalled for the class instance.

Version info

Added in LCL version 4.0.
