Method Detail

• drawBar

  public abstract void drawBar​(java.awt.Graphics g,
                               int x,
                               int y,
                               int width,
                               int height)

  Draws a bar. The whole region described by x, y, width and height is available for drawing in.

  Parameters:

  g - graphics context

  x - left X coordinate of region (lowest X value permitted)

  y - lower Y coordinate of region (lowest Y value permitted)

  width - width of region (x+width is highest X value permitted)

  height - height of region (y+height is highest Y value permitted)

• drawEdge

  public void drawEdge​(java.awt.Graphics g,
                       int x,
                       int y1,
                       int y2)

  Draws the edge of a bar. This can be invoked to draw the boundary between one bar and its immediate neighbour; the edge described by the call's parameters is not the edge of the block representing the bar's data, but the edge between the current bar and its neighbour on one side or the other, so it may go up or down from the Y value.

  The default implementation does nothing, which is correct for many forms.

  Parameters:

  g - graphics context

  x - x position of the edge

  y1 - one y value of the edge

  y2 - other y value of the edge

• isOpaque

  public boolean isOpaque​()

  Indicates whether this bar form is as opaque as the colour of the supplied graphics context. If it adjusts the alpha of the supplied colour, it must return false.

  Returns:

  true iff alpha is not adjusted

• toString

  public java.lang.String toString​()

  Overrides:

  toString in class java.lang.Object
