gdkWindowGetInternalPaintInfo: gdkWindowGetInternalPaintInfo

In RGtk2: R Bindings for Gtk 2.8.0 and Above

Description

If you bypass the GDK layer and use windowing system primitives to draw directly onto a GdkWindow, then you need to deal with two details: there may be an offset between GDK coordinates and windowing system coordinates, and GDK may have redirected drawing to a offscreen pixmap as the result of a gdkWindowBeginPaintRegion calls. This function allows retrieving the information you need to compensate for these effects.

Usage

gdkWindowGetInternalPaintInfo(object)

Arguments

object

a GdkWindow

Details

This function exposes details of the GDK implementation, and is thus likely to change in future releases of GDK.

Value

A list containing the following elements:

real.drawable	location to store the drawable to which drawing should be done. [ out ]
x.offset	location to store the X offset between coordinates in window, and the underlying window system primitive coordinates for *real.drawable. [ out ]
y.offset	location to store the Y offset between coordinates in window, and the underlying window system primitive coordinates for *real.drawable. [ out ]
