Swingx DefaultColumnControlPopup with still open menu

Question

I have MyTable which is extension of the JXTable:

public class MyTable extends JXTable{...}

Works fine as expected. Now I want to let DefaultColumnControlPopup menu still open after click onto element in popup menu so user can do multiple clicks without annoying clicks on ColumnControlButton.

Does someone know how to do it?

I had been trying to solve based on this tutorial but without success.

Answer 1

After some elaboration, it's easy if one know how to do it - as obvious...

Whole solution for others:

I have class in which I'm using JXTable:

JXTable myTable = new JXTable(new MyTableModel())
...use_table_as_usually...

class for the table:

public class MyTable extends JXTable{
    public MyTable(AbstractTableModel model){
        super(model);
        //remove items for horizontal scrollbar, pack and packall
        this.getActionMap().remove("column.horizontalScroll");
        this.getActionMap().remove("column.packAll");
        this.getActionMap().remove("column.packSelected");
        //first two columns should be shown permanently
        ColumnControlButton controlButton = new ColumnControlButton(this){
            @Override
            protected ColumnControlPopup createColumnControlPopup(){
                return (new NFColumnControlPopup());
            }

            class NFColumnControlPopup extends DefaultColumnControlPopup{
                @Override
                public void addVisibilityActionItems(List<? extends AbstractActionExt> actions){
                    for(int i = 0; i < actions.size(); i++){
                        AbstractActionExt action = actions.get(i);
                        JCheckBoxMenuItem chk = new JCheckBoxMenuItem(action);
                        chk.setUI(new KeepOpenCheckBox());
                        //disable first two items but they will be still shown greyed
                        if(i == 0 || i == 1){
                            chk.setEnabled(false);
                            chk.setSelected(false);
                        }
                        else{
                            chk.setEnabled(true);
                            chk.setSelected(true);
                        }
                        chk.addItemListener(action);
                        super.addItem(chk);
                    }
                }
            }
        };
        this.setColumnControl(controlButton);
    }
}

and finaly custom class to keep ColumnControlPopup open:

public class KeepOpenCheckBox extends BasicCheckBoxMenuItemUI{
    public static ComponentUI createUI(JComponent c){
        return new KeepOpenCheckBox();
    }

    protected void doClick(MenuSelectionManager msm){
        menuItem.doClick(0);
    }
}

That's all. In this example are mixed 3 things: -how to remove unwanted items for horizontal scrollbar, pack and packall; -how to disable some column controls from ColumnControlPopup but keep them showed with grey and without check mark; -how to keep ColumnControlPopup open after click on JCheckBoxMenuItem;

Solution is based on some resources I have found around on the Internet but some informations was old or not working (works in JMenu but no in popup menu).
