Detailed Description

This class lets us take code that draws into an GDK drawable and lets us use it to draw into any Thebes context.

The user should subclass this class, override DrawWithGDK, and then call Draw(). The drawing will be subjected to all Thebes transformations, clipping etc.

Member Function Documentation

void gfxGdkNativeRenderer::Draw	(	gfxContext *	ctx,
		nsIntSize	size,
		PRUint32	flags,
		GdkColormap *	colormap
	)

Parameters:

	flags	see above
	bounds	Draw()'s drawing is guaranteed to be restricted to the rectangle (offset.x,offset.y,bounds.width,bounds.height)
	dpy	a display to use for the drawing if ctx doesn't have one

virtual nsresult gfxGdkNativeRenderer::DrawWithGDK	(	GdkDrawable *	drawable,
		gint	offsetX,
		gint	offsetY,
		GdkRectangle *	clipRects,
		PRUint32	numClipRects
	)			[pure virtual]

Perform the native drawing.

Parameters:

	offsetX	draw at this offset into the given drawable
	offsetY	draw at this offset into the given drawable
	clipRects	an array of rects; clip to the union
	numClipRects	the number of rects in the array, or zero if no clipping is required
