Gtk CellRendererrender

void
gtk_cell_renderer_render(
GtkCellRenderer*cell,
cairo_t*cr,
GtkWidget*widget,
constGdkRectangle*background_area,
constGdkRectangle*cell_area,
GtkCellRendererStateflags
)

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.
