I want to add some new Components to my JFrame during runtime when a button is pressed. This works so far, but i have to resize the window manually to see the new components.
Is there any Action I can fire or a method to call to refresh the window? Any help appreciated. Thanks in advance.
You have to revalidate();
the frame. If that doesn't work you also have to call repaint();
Call
revalidate();
repaint();
revalidate
tells the layout manager to reset based on the new component list. This will also trigger a call to repaint.
repaint
is used to tell a component to repaint itself.
in java repaint();
working for me. while revalidate();
not working for me.
