I have another problem with the Java form.

The form has textfields, combo-box, radio buttons and checkboxes. There is also a few buttons for submit, clear and exit.

Now I have programmed the ActionListener, so that I can submit and record data to file, and I have programmed the exit button to exit out of the program.

My problem is the CLEAR button. I can clear text from the textfields and textarea, but I don't know how to clear all selections from the combobox, radio buttons and check boxes.

I have been told to use javax.swing packages, so I have looked API of Java Documentation, but I am still at loss on how to proceed further.

Can anyone help me with this problem?

It is like the RESET button of HTMl/Javascript form, where you press this buttons, and all values are clear from the form components (textfield, pull-down buttons, radiobuttons, checkboxes, etc).

Except here, I want to do exactly the same thing, but using Java programming. I can't seem to find the right method to clear selected values from pull-down menu and radiobuttons.

Can someone help?

i haven't done much gui programming in java, but in other languages i've been able to clear a dropdown box by setting the selected index to -1. radio buttons are meant to work so that there's always exactly one of them selected, so i would think you could just mark the default one selected in that case.

Your suggestion for -1 on the method for selected index, works fine. Thanks, misterhaan.

As to the radio buttons, I had wished to clear setting so that new record could be inputed.

Nevertheless, you have been very helpful in this and in other Java questions. Thanks, again.
