The parent issue when duplicating a control is indeed a bug. It will be fixed.

Your designer script is wrong. Actually you do not need it at all. You can easily dock the panel by setting the anchors to BOTH.

See the arrows in this image:

You can use Cut to delete a view.

About the "invisible views". Change their anchor to LEFT, TOP and you will see that their dimensions are 0 or negative values.

You should understand how BOTH anchor works. Horizontal BOTH means that the distance to the left edge and the distance to the right edge are constant. This means that the width will change automatically.

Play with the panel width (in the abstract designer). You will see how the width changes together with the panel. If you decrease the panel's width too much the views will disappear.

BOTH should usually used with large views that are close to their parents bounds.

Hi Erel,
I've tried to set button1's parent is activity ,but button2 and button3 still have parent is panel1. Why are button2 and button3 not show? Please test a new sourcecode.

P.S. I think that Bring to Front munu and Send to back menu have problems in post#3,I cann't do them.

It is not related to "bring to front".

They are not visible because their vertical anchor is not "correct". It is set to BOTH and the distance from the top is 360. So when you rotate the device their height becomes a negative value.

You should only use BOTH for large views that should fill the available area.

Don't use BOTH anchor if you want the size to be equal.

I've just uploaded a short video that demonstrates the usage of anchors: http://www.b4x.com/android/forum/threads/designer-anchors-video-example.36507/

Hi Erel,
Your video cann't explain more than I get understand.

Please attached file, I don't see width property(See only height). In H. Anchor or V. Anchor ,I cann't select unAnchored option.

"Unanchored" = LEFT for horizontal and TOP for vertical.

Yes, the parent can be a panel or activity.
