java 1.7
public class AccountsScroller extends JInternalFrame implements ActionListener, PaginationListener {
...
}
这里是我如何从JFrame打开InternalFrame
public void openInternalFrame(JInternalFrame newInternalFrame, Boolean isMaximize, Dimension dimension) {
try {
currentInternalFrame.setClosed(true);
currentInternalFrame = newInternalFrame;
addInternalFrame(currentInternalFrame, isMaximize, dimension);
} catch (PropertyVetoException ex) {
logger.error(ex.getMessage(), ex);
}
}
private JDesktopPane desktop;
desktop = new JDesktopPane();
private void addInternalFrame(JInternalFrame internalFrame, Boolean isMaximize, Dimension dimension) {
desktop.add(internalFrame); // 321 line
try {
internalFrame.setSelected(true);
if (isMaximize != null && isMaximize) {
internalFrame.setMaximum(true);
} else {
internalFrame.setSize(dimension);
}
} catch (java.beans.PropertyVetoException e) {
logger.error(e.getMessage(), e);
}
}
但是当我再次打开它时，出现错误：
