Renderings

Detailed Description

Built-in rendering functions for the progressbar widget.

These function may be passed to gwinSetCustomDraw() to get different progressbar drawing styles.

Note

In your custom progressbar drawing function you may optionally call these standard functions and then draw your extra details on top.

These custom drawing routines don't have to worry about setting clipping as the framework sets clipping to the object window prior to calling these routines.

gwinProgressbarDraw_Image()

void gwinProgressbarDraw_Image	(	GWidgetObject *	gw,
		void *	param
	)

Renders a progressbar using an image.

Parameters

[in]	gw	The widget object (must be a progressbar handle)

The image is tiled to fill the active area of the progressbar. The normal colors apply to the border and inactive area and the dividing line between the active and inactive areas. No checking is done to compare the dimensions of the progressbar to the size of the image. Note text is drawn on top of the image.
