I have created a form in netbeans with two radio buttons in a button group with a text box. Box 1 = Yes Box 2 = No when form loads no is already selected. I want the text box to be ivisible until user selects yes. but everything I have tried is not working. I put this in the form init part txtMajorAmt.setVisible(false); did not work. But after everything is loaded if I click on yes then no it starts working correct. any help would be appreciated.
Thank you.
Jump to Posteverything I have tried is not working.
Could you make a small, simple complete program that compiles, executes and shows the problem?
Jump to PostThere may be a problem with your ItemStateChanged methods. They will be called whenever the state changes - ie they become selected or deselected, but your code is intended to run only when the state becomes selected (?)
Jump to PostDoes the textfiele ever show with the code you posted?

here's the file
There may be a problem with your ItemStateChanged methods. They will be called whenever the state changes - ie they become selected or deselected, but your code is intended to run only when the state becomes selected (?)
Does the textfiele ever show with the code you posted?
Only if I remove the line in Public new jframe()
txtMajorAmt.setVisible(false);
then it will work if i click on yes then no. but i want it to be invisible when it is loaded.
Try calling the textfield's container class's validate method so it knows there has been a change to one of its components.
I just re-read this thread, and nowhere do you state exactly what is wrong with the behaviour. Can you please explain, one step at a time, what the visibility of the text field should be and what it actually is at each step?
