}the problem is in westPanel; how we can typed text from the Jlabel near JCombobox
now - text from combobox we can see, and text from label - don't.
and one of condition is don't crash massive of JCombobox and Jlabel
please help me

Answer 1

if if was different mod then only create many vertical Jpanels, with pair jlabel, jcombobox, please write...i don't want to do this because it wil bee many references on Jpanels-> many memory..
