Is there an easy way to show a PopupMenu without loosing a focus in current field?
In more details - I’m implementing an autocomplete combobox with drop-down list (see the http://www.rawmaterialsoftware.com/viewtopic.php?f=6&t=5829 for my original idea). And right now, when user is typing something in the texteditor (Label), depending on the content I want to show a PopupMenu with some dynamic set of choices. I have everything ready, and PopupMenu shown with proper set of items, but when it is shown - TextEditor looses the focus - user can not continue typing. I want to shown PopupMenu only as optional “hint” which user can use by mouse or by pressing key-down.
What will be your hints to achieve this? One way can be - reimplementing PopupMenu::Window (because it is private class - no way to use it directly for some needs). Another way can be using a ListBox for such menu.
