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.
