Example 16 with SWTGraphics

use of org.eclipse.draw2d.SWTGraphics in project dbeaver by serge-rider.

the class GraphicsToGraphics2DAdaptor method createSWTGraphics.

/**
 * This is a helper method used to create the SWT Graphics object
 */
private void createSWTGraphics() {
    // we need this temp Rect just to instantiate an swt image in order to
    // keep state, the size of this Rect is of no consequence and we just set it
    // to such a small size in order to minimize memory allocation
