Question

I am using org.eclipse.ui.dialogs.CheckedTreeSelectionDialog, to display a list of values. I want to select(check) all the values by default. Can you please let me know how this can be done.

Answer 1

You can set which nodes are checked initially (on dialog creation), by using the setInitialElementSelections method.

CheckedTreeSelectionDialog dlg = new CheckedTreeSelectionDialog(shell, 
    new cLabelProvider(), 
    new cContentProvider());
dlg.setInput(model);
dlg.setInitialElementSelections(model.getAllElements());
