To Add Minimize /Maximize button to JDialog orJPanel

Question

Is it possible to add maximize/minimize button to the JDialog? if not then can we add these buttons to JPanel?

I have a JPanel and inside that panel there is a JDialog.I want to add a minimize/maximize button such that when that button is clicked JDialog and the components under JDialog get adjusted according to the JPanel. like when i click maximize then jpanel should get enlarged and components inside that panel(JDialog) also get enlarged and vice versa for minimize button. The solution I got from here is for JPanel inside a JFrame. But my JPanel is standalone only.

Answer 1

Is it possible to add maximize/minimize button to the JDialog?

• not, don't do that, (even there are a few dirty hacks) you can to JDialog.setUndecorated and add required Windows decoration back, notice resources for JDialog/JWindow came from Native OS, valid for SystemLookAndFeel only and could be CrossPlatform sensitive

if not then can we add these buttons to JPanel?

• yes, but you can to use JOptionPane and with modified contents, there you can put any JComponents and/with returns value too

Answer 2

JDialog: No.

JPanel: Yes, simply use JButtons setting the JFrame#setMaximizedState value, in the listeners, but not on JDialog.
