DESCRIPTION

Gtk2::Ex::CellRendererWrappedText is a Gtk2::CellRendererText that automatically updates the wrap-width of the of the renderer so that the text always fills (or shrinks to match) the available area.

Gtk2::Ex::CellRendererWrappedText also handles editing of strings that span multiple lines. Gtk2::CellRendererText only displays multi-line strings on one line while in edit mode, regardless of the wrap-wdith of the renderer.

Pressing <Esc> whil in edit mode cancels the edit. Pressing <Ctrl+Enter> moves to the next line. Pressing <Ctrl+Enter> or focusing out of the render finishes editing and emits the 'edited' signal on the renderer.
