B4J Question Getting a list of panes

[Pelky]

I have pane with a number of panes on it. I need to access a pane using code and then to be able to change the labels within it.

Is this possible and if so could someone point me in the right direction... I did try GetAllviewsRecursive looking for panes but when running I get an error

Any help would be appreciated

Please post the error, easier to help you.

For each v as node in p0.getallviewsrecursive
If v is pane then
Dim p as pane = v
For each c as node in p.getallviewsrecursive
If c is label then
log(c.text)
End if
Next
End if
Next

This code helps you if you are getting something unexpected while iterating

You only need one loop as getAllViewsRecursive will look inside all of the child panels.

    For Each v As Node In MainForm.RootPane.getallviewsrecursive ' of wherever you want to start
        If V Is Label Then
            Log(V.As(Label).Text)
            Log(V.As(Label).Tag)
        End If
    Next

Should do it.

Cross platform solution:

   For Each v As B4XView In MainForm.RootPane.getallviewsrecursive ' of wherever you want to start
        If V Is Label Then
            Log(V.Text)
            Log(V.Tag)
        End If
    Next

Note that buttons, edittexts, checkboxes and a few other views are actually subclasses of label and will also return True for V Is Label.
