gtkCellRendererRender: gtkCellRendererRender

Description Usage Arguments Author(s)

View source: R/gtkFuncs.R

Description

Invokes the virtual render function of the GtkCellRenderer. The three passed-in rectangles are areas of window. 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. expose.area is a clip rectangle.
