LostFocus and SwingUtilities.invokeLater()

[dharmesh baveja]

Hi,
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:
1.invokelater
2.processing to be done in button_actionperformed().
Pls help me urgently!!
Thanks in advance.
Dharmesh

If youare using Java 1.3 or later, you can use the class InputVerifier.
myTextField.setInputVerifier(aVerifier);
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.
