B4J Question How to create absolute or relative UI layout?

[Ju Yang]

Hi,

I want to use internal designer from B4J to do the following UI layout:

a. place a panel on top of a form, and set this panel always at the top of the form;
b. place the second panel onto form, and set it position as match client of the form;

I just want to create this type of layout in order to make the layout auto relatively positoned on form, but didn't find any properties of the panel to set, like match parent, match client or always top similar properties used in visual basic, delphi etc. tools.

Could any expert to post good suggestions for my question?

You should use anchors for this. Setting the anchors to BOTH will cause the control to grow together with the parent.

For more advanced modifications you can use the designer script.

It is the same as in B4A: https://www.b4x.com/android/forum/threads/16120/#content (there is no AutoScale feature in B4J).
