B4J Question [SOLVED] From innernode to previous state... ?

[Magma]

Hi there...

Let's say we have a pane and a scrollpane...

pane1.AddNode(scrollpane1,0,0,pane1.Width,pane1.Height)
pane1=scrollpane1.InnerNode

You set a pane to scrollpane as innernode... how can i return it to previous state programmatically ?

Thanks in advance...

Your example does not make sense, by overwriting the pane with the scrollpane's inner node, the scrollpane will have no parent.

What are you trying to do?

I have a sub that i am calling more than one time so i want to remove nodes and make the panes be like first time

Because the next time i will call it again will be new into them...

example:

'at globals the scrollpane and pane

sub loadagain
   If ascroll.IsInitialized Then
        'rulerpane=
        'trackspane=              'seems must do something here.. ?
        'timepane=
        'myPane=
    End If
   
    ascroll.Initialize("ascroll1")
    trackscroll.Initialize("bscroll1")
    rulerscroll.Initialize("cscroll1")

   trackspane.AddNode(trackscroll,0,0,trackspane.Width,trackspane.Height)
   trackspane=trackscroll.InnerNode
   trackscroll.SetHScrollVisibility("NEVER")
   trackscroll.SetVScrollVisibility("NEVER")
     
   rulerpane.AddNode(rulerscroll,0,0,rulerpane.Width,rulerpane.Height)
   rulerpane=rulerscroll.InnerNode
   rulerscroll.SetHScrollVisibility("NEVER")
   rulerscroll.SetVScrollVisibility("NEVER")

  myPane.AddNode(ascroll,0,0,myPane.width,myPane.Height)
  myPane=ascroll.innernode

'.............

end sub

OK, but I still don't understand why you need to assign the scrollpane's inner node to it's parent. That could cause all sorts of problems.

Because i want to have as scrollable pane ? inside of it i ll have many object label and etc...

So what the solution to return at first state.. ?

I have actually problem with that:

if i move my example/app_start to a sub and reload it i ll have messed srollpane / pane...

Use ScrollPane.LoadLayout. It will be simpler and work better.

Got it!

@Erel ....i am sharing the code with all in forum... you can create a control or library erel (who knows) - i know that will help many
