TreeComboBox with multiple selection or checkboxes

[td84]

Hello,

i would like to use in a project TreeComboBox like here (http://undocumentedmatlab.com/blog/usin ... ombo-boxes) and combine it with checkboxes. The Tree should then allow multiple selections. This means, someone should be able to select the leafs of the tree separately or a complete node could be selectable (selecting all leafs automatically). Is it possible to expand TreeComboBox with checkboxes, or is there an option to have a TreeComboBox more then one selected items at a time?

At the end, i would like to have something like this (https://www.jstree.com/) in Java.

Can you provide some simple code?

Thanx in advance, Daniel

Unfortunately it needs quite an effort to get it working. I can add this code to show a CheckBoxTree in the combobox but it still behaves like a normal tree (a single click will dismiss the popup). If you really need it, you will have to create your own customize combobox. Try to create your own popup panel subclass to do it. In the CheckBoxListComboBox, we created MultiSelectListChooserPanel and CheckBoxListChooserPanel. Both have OK and Cancel buttons. You can do the same thing except using CheckBoxTree.

Code: Select all

        ExComboBox treeComboBox = new TreeExComboBox() {
            @Override
            protected JTree createTree(TreeModel model) {
                return new CheckBoxTree(model);
            }
        };
