java - TableColumnModelListener. JPanel revalidate() method ruins swing elements composition -

problem description:

originally there 2 tables:

at top of left table there 2 elements: jtextfield , jcombobox, set 1 separate jpanel. these 2 elementes needed table filtering purposes, is, changing selected combo box element or typing in jtextfield table on left filtered out.

i tried implement tablecolumnmodellistener interface in order connect jtextfield , jcombobox elements table. result not expected: revalidate() method called uppon jpanel container object ruined whole swing elements composition. outcome of experiment showed in next picture:

notice

tableresizelistener1 = new tableresizelistener(datatable1table, filterpanel);

part. table columns connected corresponding jpanel elements (jtextfield , jcombobox in example). can comment line out if want observe how composition without connected elements.

tableresizelistener class. problem lurks.

the line

filterrow.revalidate();

is responsible bug. tried phone call repaint(), validate(), resulted in not such smooth visual experience.

how can connect elements outside of jtable without ruining visual composition?

comment line out prepare problem.

jscrollpane4.setpreferredsize(new java.awt.dimension(30, 30));
