Hi ,

I tested designer script with simple layout have 3 objects.
-Panel_Parent (with default properties) is the first panel
-Panel_Child (with default properties) is in the Panel_Parent
-Label1 (with default properties) is in the Panel_Child

The variants is 320 x 480 ,scale = 1 (160 dpi )

Please check the first attached image.




Then I ran script:
B4X: 
'All variants script
'AutoScaleAll
Panel_Parent.SetLeftAndRight(0,100%x)
Panel_Child.SetLeftAndRight(20,50%x)
Label1.SetLeftAndRight(0,100%x)

I expect the Label1 will be width 100% in the Panel_Child but the width oversize than Panel_Child .

Please check the second attached image



Is this how it work or something wrong?

Best Regards,
pmt

You are doing it wrong, this line:
B4X: 
Panel_Child.SetLeftAndRight(20,50%x)
You are centering it using the ACTIVITY as parent, you should use the PARENT PANEL, also, you have to use dip.

e.g.
B4X: 
Panel_Child.SetLeftAndRight(20dip ,50%x)

Thank you for your reply NJDude.

I tried
B4X: 
Panel_Child.SetLeftAndRight(20dip,50%x)
Or
B4X: 
Panel_Child.SetLeftAndRight(0,50%x)

But not work , the Label1 's width still oversize than Panel_Child's width.

My point is why the Label1's width oversize than Panel_child 's width ?

Click to expand...

OK , I tried.
B4X: 
Panel_Child.SetLeftAndRight(0,Panel_Parent.Width/2)
Label1.SetLeftAndRight(0,Panel_Child.Width)

It 's work as I expected.


Thanks you.
