    • Method Detail

      • getPreferredScrollableViewportSize

        public java.awt.Dimension getPreferredScrollableViewportSize()
        Returns the preferred size of the viewport for a view component. For example the preferredSize of a JList component is the size required to accommodate all of the cells in its list however the value of preferredScrollableViewportSize is the size required for JList.getVisibleRowCount() rows. A component without any properties that would effect the viewport size should just return getPreferredSize() here.
        Specified by:
        getPreferredScrollableViewportSize in interface javax.swing.Scrollable
        Returns:
        The preferredSize of a JViewport whose view is this Scrollable.
        See Also:
        JComponent.getPreferredSize()

      • getScrollableUnitIncrement

        public int getScrollableUnitIncrement​(java.awt.Rectangle visibleRect,
                                      int orientation,
                                      int direction)
        Components that display logical rows or columns should compute the scroll increment that will completely expose one new row or column, depending on the value of orientation. Ideally, components should handle a partially exposed row or column by returning the distance required to completely expose the item.
        Specified by:
        getScrollableUnitIncrement in interface javax.swing.Scrollable
        Parameters:
        visibleRect - The view area visible within the viewport
        orientation - Either SwingConstants.VERTICAL or SwingConstants.HORIZONTAL.
        direction - Less than zero to scroll up/left, greater than zero for down/right.
        Returns:
        The "unit" increment for scrolling in the specified direction. This value should always be positive.
        See Also:
        JScrollBar.setUnitIncrement(int)

      • getScrollableBlockIncrement

        public int getScrollableBlockIncrement​(java.awt.Rectangle visibleRect,
                                       int orientation,
                                       int direction)
        Components that display logical rows or columns should compute the scroll increment that will completely expose one block of rows or columns, depending on the value of orientation.
        Specified by:
        getScrollableBlockIncrement in interface javax.swing.Scrollable
        Parameters:
        visibleRect - The view area visible within the viewport
        orientation - Either SwingConstants.VERTICAL or SwingConstants.HORIZONTAL.
        direction - Less than zero to scroll up/left, greater than zero for down/right.
        Returns:
        The "block" increment for scrolling in the specified direction. This value should always be positive.

        JScrollBar.setBlockIncrement(int)

      • getScrollableTracksViewportWidth

        public boolean getScrollableTracksViewportWidth()
        Return true if a viewport should always force the width of this Scrollable to match the width of the viewport. For example a normal text view that supported line wrapping would return true here, since it would be undesirable for wrapped lines to disappear beyond the right edge of the viewport. Note that returning true for a Scrollable whose ancestor is a JScrollPane effectively disables horizontal scrolling.
        Specified by:
        getScrollableTracksViewportWidth in interface javax.swing.Scrollable
        Returns:
        True if a viewport should force the Scrollables width to match its own.

      • getScrollableTracksViewportHeight

        public boolean getScrollableTracksViewportHeight()
        Return true if a viewport should always force the height of this Scrollable to match the height of the viewport. For example a columnar text view that flowed text in left to right columns could effectively disable vertical scrolling by returning true here.
        Specified by:
        getScrollableTracksViewportHeight in interface javax.swing.Scrollable
        Returns:
        True if a viewport should force the Scrollables height to match its own.
