Can anyone give explanation and an example of Container usage?
E.g. I am trying to find JProgressBar, and all the find method has Container as the first param.:
JProgressBar pb = JProgressBarOperator.findJProgressBar([Container cont]);
I supposed that JFrame or JDialog etc. could be used (cast) as Container, but it is not. So what is it?
The solution is to get Container of parent element by .getContentPane():
JFrameOperator mf = new JFrameOperator("Main Frame");
JDialogOperator jd = new JDialogOperator(mf, ""); // dialog that contains JProgressBar has no name
JProgressBar pb = JProgressBarOperator.findJProgressBar(jd.getContentPane());
