exopy.utils.widgets.qt_tree_widget module

Tree widget for enaml.

This tree widget has limited functionality, it supports only : - single selection - single column tree - no undo capabilities - single TreeNode fitting an object.

It should be used with the TreeNode declarative class and the Menu item given in qt_tree_menu.enaml.

This is vastly inspired from TraitsUI implementation.
