Virtual Method

GtkCellRendererrender

Declaration [src]

void
render (
  GtkCellRenderer* cell,
  cairo_t* cr,
  GtkWidget* widget,
  const GdkRectangle* background_area,
  const GdkRectangle* cell_area,
  GtkCellRendererState flags
)

Description [src]

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.
