public class HierarchicalGridLayer extends GridLayer
HierarchicalGridLayer is a background layer that provides a dual-level coordinate system (Major/Minor).

Unlike the standard GridLayer, this implementation reduces visual cognitive load by interleaving a secondary "Major" grid over a "Minor" point-based texture.

    • setSpacing

      public void setSpacing(org.eclipse.draw2d.geometry.Dimension spacing)
      Description copied from class: GridLayer
      Sets the horizontal and vertical spacing of the grid. A grid spacing of 0 will be replaced with the default spacing. A negative spacing will cause no grid lines to be drawn for that dimension.
      Overrides:
      setSpacing in class GridLayer
      Parameters:
      spacing - A Dimension representing the horizontal (width) and vertical (height) gaps

    • setMajorInterleave

      public void setMajorInterleave(int majorInterleave)

    • paintGrid

      protected void paintGrid(org.eclipse.draw2d.Graphics g)
      Description copied from class: GridLayer
      Paints the grid. Sub-classes can override to customize the grid's look. If this layer is being used with SnapToGrid, this method will only be invoked when the visibility property is set to true.
      Overrides:
      paintGrid in class GridLayer
      Parameters:
      g - The Graphics object to be used to do the painting
