Question

I have a JFrame and this JFrame has a JButton.

I want in JButton first show JDialog (display "Please wait") and execute other code then closing JDialog.

But when showing JDialog stopped to execute other code on JButton.

Answer 1

Start the other processing on a Thread (e.g. in a SwingWorker) and at the start of it, call modalDialog.setVisible(true). At the end of the task call setVisible(false).
