getPreferredSize
public Dimension getPreferredSize(JComponent c)
Description copied from class: BasicScrollBarUI
A vertical scrollbar's preferred width is the maximum of preferred widths of the (non null
) increment/decrement buttons, and the minimum width of the thumb. The preferred height is the sum of the preferred heights of the same parts. The basis for the preferred size of a horizontal scrollbar is similar.
The preferredSize
is only computed once, subsequent calls to this method just return a cached size.
- Overrides:
-
getPreferredSize
in classBasicScrollBarUI
- Parameters:
-
c
- theJScrollBar
that's delegating this method to us - Returns:
- the preferred size of a Basic JScrollBar

getMinimumThumbSize
protected Dimension getMinimumThumbSize()
Description copied from class: BasicScrollBarUI
Returns the smallest acceptable size for the thumb. If the scrollbar becomes so small that this size isn't available, the thumb will be hidden.
Warning : the value returned by this method should not be be modified, it's a shared static constant.
- Overrides:
-
getMinimumThumbSize
in classBasicScrollBarUI
- Returns:
- The smallest acceptable size for the thumb.
- See Also:
BasicScrollBarUI.getMaximumThumbSize()
setThumbBounds
protected void setThumbBounds(int x, int y, int width, int height)
This is overridden only to increase the invalid area. This ensures that the "Shadow" below the thumb is invalidated
- Overrides:
-
