How can I have this widget effect in Eclipse platform?

Question

Well, my project now demands such a widget in user interface with the requirements as follows:
This widget can display both text, icon, and even button. If the text on it is too long to display completely, omission marks should replace the redundant words. It is also selectable which is similar to a cell in the JTable, but it should support displaying icons as I said, and should only be scaled in size horizontally but never vertically.
Fortunately, I find that a component in the dialog shown during build or update process meets my request. Does anybody who is familiar with SWT know
how this is managed? That is, which widget(s) should I use? Or can Swing meet my demand? By the way, here is the capture image of eclipse dialog I concerned: http://freehost21.websamba.com/utarget/Eclipse_snap.jpg
Many many thanks!

Widgets. You'll need to probably create a subclass of JPanel, which will have a JLabel for the icons, and a JButton.
You'll probably need to call setPreferredSize(..) on the button to obtain the text trailing effect when the text overflows the boundaries.
Also, you could add a mouseListener to the panel to create the selection effect when it is clicked, or when any of its sub components are clicked. (recursion methods help to achieve this).
Scaling in size, now that is tricky. To do this, you'll probably have to calculate the width of the panel manually, by summing up the heights of the components and maintaining a fixed width. No an easy task though.
This is a nice component, so get writing. Here is a little help with the recursion
public void setComponentEnabled(Component c, boolean b) {
   c.setEnabled(b);
   if(c instanceof Container) {
        Container co = (Container)c;
        for(int x = 0; x < co.getComponents().length; x++) {
              setComponentEnabled( co.getComponents()[x], b);
}Go on and have some fun. Check in if you have any more problems. Other are always willing to help if they can.
