CellArea.requestRenderer

void requestRenderer(gtk.cell_renderer.CellRenderer renderer,  gtk.types.Orientation orientation,  gtk.widget.Widget widget,  int  forSize,  out  int  minimumSize,  out  int  naturalSize)

This is a convenience function for [gtk.cell_area.CellArea] implementations to request size for cell renderers. It’s important to use this function to request size and then use [gtk.cell_area.CellArea.innerCellArea] at render and event time since this function will add padding around the cell for focus painting.

Parameters

`renderer`	the [gtk.cell_renderer.CellRenderer] to request size for
`orientation`	the [gtk.types.Orientation] in which to request size
`widget`	the [gtk.widget.Widget] that area is rendering onto
`forSize`	the allocation contextual size to request for, or -1 if the base request for the orientation is to be returned.
`minimumSize`	location to store the minimum size
`naturalSize`	location to store the natural size
