Hi Torsten,
This is a bug with DnD in ULCInternalFrame:
https://www.canoo.com/jira/browse/UBA-6967
As workaround, you need to extend ULCInternalFrame as follows:
Server-side class: (remember to change the typeString appropriately when
client and server are not running in DevelopmentRunner)
public static class ULCMyInternalFrame extends ULCInternalFrame {
protected String typeString() {
return UIMyInternalFrame.class.getName();
}
}
Client-side class:
public static class UIMyInternalFrame extends UIInternalFrame {
protected Object createBasicObject(Anything args) {
return new SpecialInternalFrame();
}
public static class SpecialInternalFrame extends
UIInternalFrame.MyInternalFrame {
protected JRootPane createRootPane() {
return new MyRootPane();
}
public static class MyRootPane extends JRootPane {
protected Container createContentPane() {
JPanel result = new JPanel();
result.setName(this.getName() + ".contentPane");
result.setLayout(new BorderLayout() {
/*
* This BorderLayout subclass maps a null
constraints to CENTER. Although the reference
* BorderLayout also does this, some VMs throw an
IllegalArgumentException.
*/
public void addLayoutComponent(Component comp,
Object constraints) {
if (constraints == null) {
constraints = BorderLayout.CENTER;
}
super.addLayoutComponent(comp, constraints);
}
});
return result;
}
public void setGlassPane(Component glass) {
if (glass.getClass().getName().endsWith("DnDGlassPane"))
{
return;
}
super.setGlassPane(glass);
}
}
}
}
Please try this out and let me know if it worked for you.
Thanks and regards,
Janak
