JInternalFrame GlassPane behavior between Java 5 and Java 6
I have an application that has JDesktopPane in which Several JInternalFrame subclasses are added.
The JInternalFrame subclass installs a GlassPane thusly:
setGlassPane(new Component(){
publicvoid setVisible(boolean b){
super.setVisible(false);
}
});
Under Java 5 this would prevent the JInternalFrame from
being raised when the mouse was clicked in the content
area of the internal frame. Our application had several
integrated features that rely on the internal frame not being
raised during user interaction. But would be raised when
the user clicks on the title bar of the internal frame.
The behavior that we are emulating is similar to the X
windows feature of the focus following the mouse but with
out the internal frame gaining focus or raising when the
mouse enters the internal frame or is clicked on the
content area.
Below is an example program
When executed under Java 5 clicking on the button in the
internal frame invokes the button but does not raise the
frame.
When executed under Java 6. The frame is always raised.
The desired behavior is that the frame is raised only when
the title bar or frame handles are clicked.
Does anyone have any ideas on this one.
Cheers,
David
