I am facing proble , which is as below:
1.I have got a JtextField on which i am doing validation on lostfocus()
2.But when one clicks the some button on Frame and focus was on the JTextField , two things happen:
a)Lost Focus happens on JtextField.
b)Jbutton_action_perfomed happens.
3. I want on such a click on button , the validation to be skipped out.
4. I think i can handle this case by invokelater() , but how?
5.Desired is:
1. On lostfocus , validation() will be excuted and returning focus back to JTextFiled.
2.On button click , i want to skip the execution of validation() by setting flag & skipping the run method of thread in invokelater(). This can be done in button_actionprformed().
Please send me the rough outline code for:
2.processing to be done in button_actionperformed().
Pls help me urgently!!
Thanks in advance.

If youare using Java 1.3 or later, you can use the class InputVerifier.
And if you want to avoid the check (for example with a cancel button), you can see the method setVerifyInputWhenFocusTarget.

You can look also to the class PlainDocument if you want some
"clever" behaviour for your widget.
