I like to load the content of a pane only after the pane is visible the first time. 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? |

Hi,

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.
