JInternalFrame to front and focussed
How does one push a JInternalFrame
开发者_高级运维 to the top of all the frames in a JDesktopPane?
try grabFocus() and requestFocus(). One of the should work. I personally used only requestFocus().
Read the JInternalFrame API and follow the link to the Swing tutorial on "How to Use Internal Frames" where you will find a working example of how to "select" the active internal frame.
In this example, a javax.swing.Action
is used to select frames from a menu.
The OP has noted that setSelected
was not working, and he needed to call activateFrame
manually. This sounds similar to an issue I was having with GTKLookAndFeel
. I had an application that was all wired up to use setSelected
to eventually trigger activateFrame
. Worked fine with Windows and Mac native look and feel; activateFrame
would get called automatically.
On Ubuntu, the system selected LaF was GTKLookAndFeel
and for whatever reason this was not calling activateFrame
. It didn't appear that setSelected
was throwing an error or anything, it just wasn't getting around to calling activateFrame
as the other LaFs seem to do. I think it's a GTKLookAndFeel
compatibility issue.
In the end I punted on this and just prohibited GTKLookAndFeel
, replacing it with Metal
. Motif
also had the compatible behavior (but it's so ugly...). The code looks something like this:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
if (UIManager.getLookAndFeel() instanceof com.sun.java.swing.plaf.gtk.GTKLookAndFeel)
UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
/*make current JInternalFrame deselected by calling JInternalFrame method setSelected(false)
*/then select new JInternalFrame using the same method; ie setSelected(true)
sample code:
try{ jframe1.setSelected(false); jframe2.setSelected(true); }catch (PropertyVetoException ex) {}
Closing a modal JInternalFrame see the post by Mr. Zen(me)
