gdkDrawDrawable

Description

Copies the width x height region of src at coordinates (xsrc, ysrc) to coordinates (xdest, ydest) in drawable. width and/or height may be given as -1, in which case the entire src drawable will be copied.

Usage

gdkDrawDrawable(object, gc, src, xsrc, ysrc, xdest, ydest, width, 
    height)

Arguments

`object`	a `GdkDrawable`
`gc`	a `GdkGC` sharing the drawable's visual and colormap
`src`	the source `GdkDrawable`, which may be the same as `drawable`
`xsrc`	X position in `src` of rectangle to draw
`ysrc`	Y position in `src` of rectangle to draw
`xdest`	X position in `drawable` where the rectangle should be drawn
`ydest`	Y position in `drawable` where the rectangle should be drawn
`width`	width of rectangle to draw, or -1 for entire `src` width
`height`	height of rectangle to draw, or -1 for entire `src` height

Details

Most fields in gc are not used for this operation, but notably the clip mask or clip region will be honored.

The source and destination drawables must have the same visual and colormap, or errors will result. (On X11, failure to match visual/colormap results in a BadMatch error from the X server.) A common cause of this problem is an attempt to draw a bitmap to a color drawable. The way to draw a bitmap is to set the bitmap as the stipple on the GdkGC, set the fill mode to GDK_STIPPLED, and then draw the rectangle.
