Java Forum / GUI / August 2004how to set focus to an AWT edit field?
Hi, I am desinging GUI, Everytime I update the plot in axes window, the focus on the edit UI control is lost. How can I set focus back to this edit field control to let the user continue his input?

To get assistance, you need to post a small, complete, compilable code example that shows the problem.

Try this form: SwingUtilities.invokeLater(new Runnable() { myComponent.requestFocus(); }); SignatureAndrei Kouznetsov http://uio.dev.java.net Unified I/O for Java http://reader.imagero.com Java image reader / ... >> u use a thread check if the focus is lost and re-assign the focus on the >> object u want > > That's exactly waht I was asking: how to re-assign the focus on the object > I want ? Well, strictly speaking, you can't force the reassignment. But if you have the desired object call requestFocus(), it will probably get focus in a reasonable time.

Post short compilable code, may be we'll find some mistake.

I am trying to do some "automatic" focusing for some other applications, not written by me, but I need to focus on a edit control on it in order to save some energy...
