gdkWindowSetBackPixmap {RGtk2} | R Documentation

## gdkWindowSetBackPixmap

### Description

Sets the background pixmap of `window`. May also be used to set a background of "None" on `window`, by setting a background pixmap of `NULL`.

### Usage

    gdkWindowSetBackPixmap(object, pixmap = NULL, parent.relative)

### Arguments

``object`` | a `GdkWindow`
``pixmap`` | a `GdkPixmap`, or `NULL`. [ allow-none ]
``parent.relative`` | whether the tiling origin is at the origin of `window`'s parent

### Details

A background pixmap will be tiled, positioning the first tile at the origin of `window`, or if `parent.relative` is `TRUE`, the tiling will be done based on the origin of the parent window (useful to align tiles in a parent with tiles in a child).

A background pixmap of `NULL` means that the window will have no background. A window with no background will never have its background filled by the windowing system, instead the window will contain whatever pixels were already in the corresponding area of the display.

The windowing system will normally fill a window with its background when the window is obscured then exposed, and when you call `gdkWindowClear`.
