(WORKAROUND) MDI Tab Groups events

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Using MDI Tabs the Workspace event   _SelectedChanged is fired each time a different Tab is clicked by user. That is good.

But when I have several Groups of Tabs, the   _SelectedChanged event does NOT always fire when user clicks different Tab if the Tab is in a different Group. It only behaves correctly if we stay in the same Group.

To explain better:  It seems each Group retains its own "Current Tab". When user clicks on any "current Tab" the Changed event does not fire -- even if Tab is in a different Group.

I expect this is Working As Designed (ie. not a bug).  But how can I detect when user clicks in a different Group ??  eg. is there a Group_Changed event?

WORKAROUND -- the Workspace_BeforeItemClick event is correctly fired for ALL times when user clicks on a Tab. Even if it is current Tab or in a different Group. So with a bit of logic I can use this event to get around the problem with  _SelectedChanged event.

But please still comment if I have missed something or there is a better way.

	Bump... Can CJ confirm if this is a bug or not. What's the purpose of a Workspace_SelectedChanged event if it does not fire when a different tab is selected ? (current version still has this "behaviour") BTW, the proposed workaround only works when the user actually "clicks" on the tab. For all other methods of selecting a different tab, this does not work (e.g. click on the contained form, keyboard, etc) [edit] For those interested, until this is fixed, the way to go is using a timer and checking the Selected property. It changes as expected: Private Sub FastTimer_Timer() Dim TabID As Long, GroupID As Long Static OldWorkspaceTabID As Long, OldWorkspaceGroupID As Long '2009-12: selectionchanged does not work between groups in 13.2 TabID = Me.CB.TabWorkspace.Selected.Index GroupID = Me.CB.TabWorkspace.FindGroup(Me.CB.TabWorkspace.Selected) If TabID <> OldWorkspaceTabID Or GroupID <> OldWorkspaceGroupID Then Me.WorkspaceSelectionChanged OldWorkspaceTabID = TabID OldWorkspaceGroupID = GroupID end if end sub Public Sub WorkspaceSelectionChanged() Set FocusForm = Me.ActiveForm ' use this FocusForm to reference the active tab End Sub
