I have a problem, I created a java application with a menu that calls several screens. When I opened some screen, I wanted my main application screen to be minimized. I tried with setvisible(false) but it did not work out as expected.
How can I do this?
Create a constructor on the secondary screens, getting a JFrame as a parameter, something like this:
public JanelaSecundaria(Frame frame) {
//...
frame.setExtendedState(JFrame.ICONIFIED);
//...
}
And when instantiating your sub windows within the main Frame, pass it as a reference:
JanelaSecundaria j2 = new JanelaSecundaria(this);
