B4J Question Trying to position a button by code, its not moving?

LucaMs said:

Uhm...

If you move the code (those 2 lines) to Sub Button1_Action, for example, it works.

B4j does not have commands like DoEvents, Invalidate, Refresh... I'm searching for a solution, but If someone (Erel? )...

#Region  Project Attributes
    #MainFormWidth: 600
    #MainFormHeight: 400
#End Region

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private Button1 As Button
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.SetFormStyle("UNIFIED")
    MainForm.RootPane.LoadLayout("form") 'Load the layout file.
    MainForm.Show
    scheme
End Sub

Sub scheme
    Button1.Left=130
    Button1.PrefHeight=66
End Sub

You don't need to invalidate the view. The drawing will appear immediately.

There is no DoEvents method in B4J (due to technical reasons).

You can split the task into several tasks and then use CallSubDelayed to start each task. Another option is to use the threading library and run this task with a background thread.

It has nothing to do with DoEvents.

1. You should manage the layout with the visual designer.
2. To change the layout of a designer view in your code then:
a. Make the change in Panel_Resize event.
b. Or prevent the layout from handling the resize event.

Ehm... I tried (before your post, then I'm not so stupid, lol) searching for some form/pane event (thank to the very useful "help of tab"), but I don't know the panel name, so I don't know the full event name.

So simply removing the tick, fixes the problem!
