CollapsiblePanel setting focus to a JTextArea

[NeoGeek83]

I have a set of Collapsible Panels which when expanded I want to have the focus set to a text input area. What is the best way to go about doing this?

I guess you can use CollapsiblePaneListener to listen to COLLAPSIBLE_PANE_EXPANDED event and call requestFocus on the text field.

Could you give me an example of how one would go about doing that?

I thought it should be easy enough to do based on my description above. Here is an example assuming the textArea is a JTextArea in the CollapsiblePane called pane. Now if you expand the CollapsiblePane, the textArea should get focus.

Code: Select all

        pane.addCollapsiblePaneListener(new CollapsiblePaneAdapter() {
            public void paneExpanded(CollapsiblePaneEvent event) {
                textArea.requestFocus();
            }
        });

I'm brand new to Java, and just now learning about how event and listeners are handled. I'm used to C++. Thanks for the help, I've got it now.

I see. Not sure about you but we found many users thought they can learn JIDE directly without learning Swing but that's not correct. JIDE is built on top of Swing and uses Swing extensively. If you already knew Swing, you will find JIDE APIs a lot easier to understand because we follow Swing design patterns and naming convention everywhere in JIDE. But if you don't know Swing at all and/or from MFC/.NET side, you will find the API is not easy to understand and get used to. That's why we suggest people to learn Swing first, or at least learn Swing and JIDE the same time. FYI.

Thanks,
