Examples with ScaledGraphics org.eclipse.draw2d.ScaledGraphics used on opensource projects

Example 1 with ScaledGraphics

use of org.eclipse.draw2d.ScaledGraphics in project cogtool by cogtool.

the class ScalableFrameFigure method paintClientArea.

     * using a scaled graphics object.
     *
     * Checks with the AView to determine if it should actually draw.
