snapshot

Description:

public virtual void snapshot (Snapshot snapshot, Widget widget, Rectangle background_area, Rectangle cell_area, CellRendererState flags)

Invokes the virtual render function of the `GtkCellRenderer`.

The three passed-in rectangles are areas in cr. Most renderers will draw within cell_area; the xalign, yalign, xpad, and ypad fields of the `GtkCellRenderer` should be honored with respect to cell_area. background_area includes the blank space around the cell, and also the area containing the tree expander; so the background_area rectangles for all cells tile to cover the entire window.

Parameters:

this	a `GtkCellRenderer`
snapshot	a `GtkSnapshot` to draw to
widget	the widget owning `window`
background_area	entire cell area (including tree expanders and maybe padding on the sides)
cell_area	area normally rendered by a cell renderer
flags	flags that affect rendering
