| | trouble with dialog boxes
Please Login to Remove!
i created a dialog box with a gauge field and a button.
all i wanted to do was after the gauge field is completed, or the button is clicked, the dialog will be closed.
i enclosed the running of the gauge field inside a thread, so that the user can still click the button.
The problem is, after the thread, when i try to close the dialog box, it throws IllegalStateException. i don't even know where the exception is coming from or why it happened.
can somebody help me on this?
