I want to have an explorer-type window with a tree on the left, a divider,
and a display on the right. I want the right side to change depending on
what is selected on the left side.
I created a SashForm and created a Tree for the left side, along with the
listeners and whatnot to know when something is selected. I can create one
widget for the right side, maybe a Table or something, but I can't figure
out how to replace the right side widget with something else when a
different item is selected in the tree. For example, I might want to
display a table when the root node is selected, but display a tree when
another item is selected.
I haven't found a way to do this in SWT. In Swing and wxWidgets there's a
replaceWindow() type API that can be used to replace the widget in a split
frame. How can this be done in SWT?
One solution I thought of was to put a Composite on the right side and
replace the contents of the Composite. But I couldn't figure out how to do
that, either.
Thanks,
Rich

You have two (at least) options
1) Dispose the widget on the right, create a new one and call
SashForm.layout(true)
2) On the right create a Composite and give it a StackLayout (in
org.eclipse.swt.custom). The Composite can parent the widgets on the right
and you can flip between which one is showing using StackLayout.topControl
and calling Composite.layout(true);
