When does a pane come in view?

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

   I like to load the content of a pane only after the pane is visible the first time.
Only the top most pane of a group of tabbed panes is in view when the application starts, so only this pane should load data.
Other panes should load data only when the user clicks on the panetab.
How do I know when a pane comes in view resp. in front?
I am grateful for each suggestion...

	In other words: Is there a way to find out which pane of a nested pane group is in front resp. on top? How do I find out in source code that PaneB is hidden behind PaneA? Dim Pane As XtremeDockingPane.Pane For Each Pane In DockingPane1 Debug.Print Pane.Title & ": ID=" & Pane.Id & ", Closed=" & Pane.Closed & ", Floating=" & Pane.Floating & ", Hidden=" & Pane.Hidden & ", Position=" & Pane.Position & ", Type=" & Pane.Type & ", Enabled=" & Pane.Enabled & ", ParentContainer.hWnd=" & Pane.ParentContainer.hWnd Next Result: PaneA: ID=0, Closed=Falsch, Floating=Falsch, Hidden=Falsch, Position=3, Type=0, Enabled=3, ParentContainer.hWnd=2032308 PaneB: ID=1, Closed=Falsch, Floating=Falsch, Hidden=Falsch, Position=3, Type=0, Enabled=3, ParentContainer.hWnd=2032308 PaneC: ID=2, Closed=Falsch, Floating=Falsch, Hidden=Falsch, Position=1, Type=0, Enabled=3, ParentContainer.hWnd=1704806 There is no hint.

	Ok, for most situations this is a solution. But i'm still no satisfied. Please look at the situation on the picture: I can notice the following actions when I click on PaneB: DockingPane1_Action: Action=17, Pane.Id=2, Pane.Title=PaneB DockingPane1_Action: Action=15, Pane.Id=1, Pane.Title=PaneA DockingPane1_Action: Action=14, Pane.Id=2, Pane.Title=PaneB For PaneA only the action 15 (PaneActionDeactivated) is fired. But action 15 is also fired when I click in the TextBox above. So I don�t know when PaneA is not in view anymore. But this is important in my application! Is there a solution?

	It was not exactly was i'm looking for, but it was an inspiration. In the _Action event I reset the handle for my panes if the action is PaneActionUnpinned or PaneActionCollapsed. So if a pane is getting visible again, I can catch the _Attach Pane where I set a handle for the visible pane and reset all handles for other panes with the same ParentContainer.hWnd. I'm still testing, but I think this will work.
