    • Method Detail

      • paint

        void paint​(org.eclipse.swt.graphics.GC gc,
                   java.lang.Object value)
        Paints the visual representation of the given value on the given GC. The actual class of the value object is determined by the use of the implementing class.

        Implementors need to respect the bounds values that may have been specified. The bounds values may affect the x and y values for all drawing operations as well as the width and heights. Implementors may use a Transform to translate the coordinates of all the drawing operations, otherwise they will need to offset each draw.

        Parameters:
        gc - GC to paint with
        value - the value being painted
      • computeSize

        org.eclipse.swt.graphics.Point computeSize​(org.eclipse.swt.graphics.GC gc,
                                                   int wHint,
                                                   int hHint,
                                                   java.lang.Object value)
        Returns the size of the given value's visual representation.
        Parameters:
        gc - convenience GC for string and text extents
        wHint - given width (or SWT.DEFAULT)
