How to diasble x button(close) December 14, 2014 11:06AM UTC
Apostolos Michaloudis 28 Posts	Hello! Is there a way to disable the red x button which closes the standalone applet window? I need something like DO_NOTHING_ON_CLOSE How can I access the main frame's code so I can do this? Do I have to create the jar file and then open it with a txt reader in order to change this parameter?I want the user to close the frame by clicking a Exit button in the simulation. Will System.exit() work for this? Also, would you consider adding this feature at frame's properties when we double click on it? Login to reply

Francisco Esquembre 237 Posts	Add this to an Initialization page. if (_view.drawingFrame instanceof JFrame) ((JFrame)_view.drawingFrame).setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); The reason for the check is that the frame may be something different if the simulation runs as an applet.
