Method Detail

draw

public void draw(Graphics gc,
                 com.klg.jclass.cell.JCCellInfo cellFormat,
                 Object o,
                 boolean selected)

Used to draw the cell. Note that the size of the cell comes from JCCellInfo.getDrawingArea(). When the renderer's draw method is called, the gc is translated to the upper-left corner of the drawing area for the cell. The "drawing area" of the cell is the region inside the borders and the margins.

Specified by:

draw in interface JCLightCellRenderer

Overrides:

draw in class JCImageCellRenderer

Parameters:

gc - Graphics context to use for drawing.

cellFormat - Cell property information.

o - Object to be rendered.

selected - Boolean value indicating whether the cell is selected.
