CheckBoxTree with DigIn

[Bosk]

How to easy change CheckBoxThree behavior with DigIn. I need functionality similar as DigIn, but if undo parent we haven't checked childs DigIn remove selection from parent, but I want save this selection for parent.

1. If we set check in parent node - all childs under parent must be cheked.
2. If we remove check in all childs - parent node must be cheked.
3. If we remove check from parent - check from child must be removed.
4. If we set check for child but parent is uncheked, we must set check to parent.

Please try extend CheckBoxTreeSelectionModel to create your own selection model. Since the item 2 in your request is kind of conflict with the concept of digIn, I cannot see an easy way to achieve this in just a few lines. The issue is that, if all children are unchecked, which selection path will you save in the selection model? If you save the parent as checked, the children nodes will be painted as checked automatically in next painting. Hence, you probably have to add a flag to distinguish the normal parent check and the empty parent check and control the behavior everywhere with the flag.

I try to extend CheckBoxTreeSelectionModel.

Code: Select all

public class MyCheckBoxTreeSelectionModel extends CheckBoxTreeSelectionModel
{

   public MyCheckBoxTreeSelectionModel(TreeModel model)
   {
      super(model);
   }
}

But I don't understand in which methods I must use flags. I try to create my own method

Code: Select all

public void removeSelectionPaths(TreePath[] paths, boolean doFireEvent)

it's don't help me, because toggleRemoveSelection and delegateRemoveSelectionPaths is not visible. May be i'm moving in a wrong way?

As we said, it's not easy to do so due to the reason we stated in the previous post. Please feel free to create your own selection model with JIDE CheckBoxTreeSelectionModel source code at https://jide-oss.dev.java.net/.

Thanks,
