This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
Its been years since I have done something with swing/awt. Just wanted to know, that in a card layout, how do you refresh one of the panels depending upon the changes of another panel.
My scenario is:
I have 3 panels in a card layout, when first loading the UI, the first panel has two radio buttons and one of them in disabled. Now on the second panel, if the user makes some changes, the radio button should be enabled when the user visits the first panel again. Right now, I am not able to achieve this. I googled a lot but did not find answers to this.
You use a reference to the radio button on the first panel, and you call its setEnabled(true) method when the user makes those changes in the second panel.
Really, it's as simple as that. However it seems like you haven't written your controller code so that it has a reference to that radio button. You should fix that problem. The controller code which is called when the second panel's action listener is called (or whatever it is which reacts to those changes) should also have a variable which refers to that radio button.
