Detailed Description

Description: Cell Renderer which handles the labels at the top of columns

Usage: This renderer will draw both the text of the column's label and if the sort order has been set to kAscendingSort or kDescendingSort it will also draw the appropriate symbol denoting the sort order of the column.

Member Function Documentation

void FWColumnLabelCellRenderer::draw	(	Drawable_t	iID,
		int	iX,
		int	iY,
		unsigned int	iWidth,
		unsigned int	iHeight
	)

virtual

Called to draw a particular cell: arguments

iID: the id for the drawable in the window. Needed in order to do calls to gVirtualX or to TGFont iX: screen x position that the cell drawing area starts iY: screen y position that the cell drawing area starts iWidth: width (x dimension) of cell drawing area. May be larger than value returned from width() iHeight: height (x dimension) of cell drawing area. May be larger than value returned from height()

Reimplemented from FWTextTableCellRenderer.
