kwin/tabbox/tabboxview.cpp
Martin Gräßlin 76f17e6de1 Here comes the new TabBox. It is a complete rewrite using a MVC approach. Here some highlights:
* Models and Delegates for Clients and Desktops
 * Horizontal, vertical and tabular layout
 * Layout of one item can be configured by an XML definition
 * A desktop item can include a client list
 * An optional second list view showing only the selected item
 * A new KCM "kwintabbox"
 * An alternative TabBox with independent settings and keybindings
 * Optional Highlight Windows effect integration
 * List scrolls instead of removing items
 * Scroll wheel support
 * Cursor key support
 * Middle click on item closes window
