Detailed Description

a ParaView specific customization of QTreeWidget.

A convenience QTreeWidget with extra features:

• Automatic size hints based on contents
• A check box added in a header if items have check boxes
• Navigation through columns of top level items on Tab.
• Signal emitted when user navigates beyond end of the table giving an opportunity to the lister to grow the table.
• Avoid grabbing scroll focus: Wheel events are not handled by the widget unless the widget has focus. Together with change in focus policy to Qt::StrongFocus instead of the default Qt::WheelFocus, we improve the widget scroll behavior when nested in other scrollable panels.
