I need to remove the Component
in the Center
of the JPanel
, but after some tries no prevail.
I tried the method here:
Removing the CENTER element from a JPanel using BorderLayout
But the answer's method produces a compile time error:
Type mismatch: cannot convert from LayoutManager to BorderLayout
Am I interpreting the answer wrong?
In addition, I am also curious if I can update just a single component from a GroupLayout. Could somebody tell me how to do it?
EDIT: @mre: Here's the code:
BorderLayout layout = panel.getLayout();
panel.remove(layout.getLayoutComponent(BorderLayout.CENTER));
Which is basically the same as in the link.
Thank you all!
You have to downcast the layout manager to BorderLayout :
BorderLayout layout = (BorderLayout) panel.getLayout();
But if you know which component is in the center, you can just remove it :
panel.add(myComponent, BorderLayout.CENTER);
...
panel.remove(myComponent);
