Item View

An item view is an extended version of a scroll area. It uses one predefined scrollable widget, called viewport. It provides an interface to perform the following operations:

• header visibility control
• row- and column-wise resizing, item alignment, item sorting
• selection handling (mode, color, behavior)

Item views provide signals to connect other widgets to it:

• activated ... left click or return pressed
• clicked ... left click
• doubleClicked ... double left click
• returnPressed

Item Viewport

The item viewport performs the mapping from model items onto flat cell indices for layouting reasons.
