Custom JScrollbar Problem (change the knob/thumb)

Question

I want to change the look of a JScrollBar.
I do this with overwriting/extending ScrollBarUI.
It´s no problem to change the outlook of the arrowbuttons by overwriting

Answer 1

Include this on your MyScrollBarUI code:

  protected void setThumbBounds(int x, int y,int width,int height)
  {
      super.setThumbBounds(x, y, 14, 14);
  }
  protected Rectangle getThumbBounds()
  {
      return new Rectangle(super.getThumbBounds().x,super.getThumbBounds().y,14,14);
  }
  protected Dimension getMinimumThumbSize()
  {
      return new Dimension(14,14);
  }
  protected Dimension getMaximumThumbSize()
  {
      return new Dimension(14,14);
  }
