TdxNavBarShowingPopupEvent Type

The procedural type of a NavBar control’s popup window display events.

Declaration

TdxNavBarShowingPopupEvent = procedure(Sender: TObject; var AAllow: Boolean) of object;

Parameters

Name Type
Sender TObject
AAllow Boolean

Remarks

Use the Sender parameter to access the NavBar control that raised a TdxNavBarShowingPopupEvent event. Cast the parameter value to the TdxNavBar class to access the control’s API members.

Assign False to the AAllow parameter to prevent a NavBar control’s popup window from appearing.

The NavBar control’s OnOverlayShowing and OnPopupShowing events reference the TdxNavBarShowingPopupEvent procedural type.
