missing TPopupMenu feature: checking for visibility

Posted by jpluimers on 2019/06/25

a method to detect when the menu was closed without a selection (i.e. none of the menuitem OnClick handlers fired). Add the unit below to your project and the form the popup menu is on will receive the custom messages defined in the unit when the menu appears or closes.

The solution by Peter Below in ExPopupList works from D5 on:  [Archive.ismissing TPopupMenu features? – Google Groups.

Now you can hook the [WayBackTControl.OnContextPopup Event for a [WayBackTPopupMenu activation, and the custom Windows messages CM_MENUCLOSED, CM_ENTERMENULOOP and CM_EXITMENULOOP to monitor the state of the popup menu.
