Examples with ContainerListener java.awt.event.ContainerListener used on opensource projects

Example 1 with ContainerListener

use of java.awt.event.ContainerListener in project JMRI by JMRI.

the class ThrottleFrame method ynstrument.

// #JYNSTRUMENT# here instantiate the Jynstrument, put it in a component, initialize the context and start it
public JInternalFrame ynstrument(String path) {
    if (path == null) {
        return null;
    }
    // everything is there
    Jynstrument it = JynstrumentFactory.createInstrument(path, this);
    if (it == null) {
        log.error("Error while creating Jynstrument " + path);
        return null;
    }
    setTransparentBackground(it);
    JInternalFrame newiFrame = new JInternalFrame(it.getClassName());
    newiFrame.add(it);
    newiFrame.addInternalFrameListener(frameListener);
    newiFrame.setDoubleBuffered(true);
    newiFrame.setResizable(true);
    newiFrame.setClosable(true);
    newiFrame.setIconifiable(true);
    newiFrame.getContentPane().addContainerListener(new ContainerListener() {

        @Override
        public void componentAdded(ContainerEvent e) {
        }

        @Override
        public void componentRemoved(ContainerEvent e) {
            Container c = e.getContainer();
            while ((!(c instanceof JInternalFrame)) && (!(c instanceof TranslucentJPanel))) {
                c = c.getParent();
            }
            c.setVisible(false);
            remove(c);
            repaint();
        }
    });
    newiFrame.pack();
    add(newiFrame, PANEL_LAYER_FRAME);
    newiFrame.setVisible(true);
    return newiFrame;
}

Example 2 with ContainerListener

use of java.awt.event.ContainerListener in project jdk8u_jdk by JetBrains.

the class JLightweightFrame method initInterior.

                clip.y = Math.max(0, clip.y);

                clip.height = Math.min(contentPane.getHeight(), clip.height);
                EventQueue.invokeLater(new Runnable() {

                    @Override

                        Rectangle c = contentPane.getBounds().intersection(clip);
                        notifyImageUpdated(c.x, c.y, c.width, c.height);
