Examples of org.eclipse.swt.graphics.GC.stringExtent()

org.eclipse.swt.graphics.GC.stringExtent()
Returns the extent of the given string. No tab expansion or carriage return processing will be performed.
The extent of a string is the width and height of the rectangular area it would cover if drawn in a particular font (in this case, the current font in the receiver).
@param string the string to measure @return a point containing the extent of the string @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT - if the string is null
@exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed

            String text = item.getName();
            String info = getInfo();

            Point extentText = gc.stringExtent(text);
            Point extentInfo = gc.stringExtent(info);
            gc.dispose();


            return new Point(Math.max(extentText.x, extentInfo.x) + 4, extentText.y + extentInfo.y + 4);
