How to remove btnTask from JToolBar?

Answer 1

i tried remove, but forgotten for repaint

Well the general code should be:

panel.remove(...);
panel.revalidate();
panel.repaint();

The revalidate() is important because it tells the panel to layout the components. Your code may work if your are removing the last component, but I doubt is will work when you remove the first component.
