Is there a way to get a JTable to display lists similar to the Windows ListView control?
Window's ListView provides a "details" view (each list item
displayed in a single row with multiple columns),a "list" view (a left to right snaking list with column width automatically adjusted to the widest entry), as well as "small icon" and "large icon" views. I can live without the icon views, but really need a single control that can toggle between a details view and list view.
Any idea how to simulate this in Java?
I need this because I am working on a Java port of a Windows app that used the common "Explorer" GUI design. If anyone would have suggestions as to other controls to use to simulate this GUI design, including a JTree replacement, "Outlook Button Bar", or advanced text editing (hyperlinks, etc.), this would be greatly appreciated.
Thanks,

Another way to do it would be to implement two TableModels. One to provide the normal list view, the other to display the details view. Or you may use the one details model, but hide the details columns by getting the TableColumnModel from the JTable and setting specific TableColumn objects to 0 maximum width. You will need to consult the Java Documentation for specific method calls as the table system is rather complicated.
The two panel approach seems to solve the problem of using different controls for the list vs. details view, and still being able to rapidly switch between the two views (controls). It is not ideal, but seems like it would work.
But even with this approach, I am faced with hand coding the list view, as I still have no control to use. This is very difficult, when you take into account things like snaking of columns, multi-select accross columns (can you even do that w/JTable?), sorting, drag and drop, etc. And it seams like JTable is the only control I could subclass, and that is not efficient, as JTable is a full blown grid, whereas I only need to display basic lists. Of course, that is why you have the separate controls in Windows: grids for complex tabular formatting/editing, list controls for vertical scrolling lists, and listview for high performance display of and toggle between basic list views.
Surely, someone else must have developed a Window's Explorer-like interface in Java? I am really hoping to
find a 3rd party listview-like control that I can purchase.

Well, since you only want to display lists have you checked out JList? Granted, you'd still have to subclass and do a fair amount of work to get this to work, but I'd think a list would be more appropriate to what you are trying than JTable. Now, one thing that would be of help in JTable is the ability to sort a column. http://manning.spindoczine

Well, I don't know of any built in objects that you can use, but the way I would go about solving this would be to actually break it down into two panels. The first panel would be the detail view, and the second panel would be the list view. The panels would reside on the same part of the frame. I would use a CardLayout to do this. Then, using some action I would switch between the two. Here is sample CardLayout code:
....
JPanel main = new JPanel(new CardLayout());
JPanel one = new JPanel();
//put the stuff onto panel one
JPanel two = new JPanel();
//put the stuff onto panel two
main.addLayoutComponent(on
main.addLayoutComponent(tw
...
public void actionPerformed(ActionEven
{
if (actionOne)
main.show(myFrame, "One");//myFrame is the parent frame
else if (actionTwo)
main.show(myFrame, "Two");
}
Basically what you then have to do is find some way of representing the two views, but at least you don't have to change an entire panel. Hope this helps a little.
