MinimalScrollPane
public MinimalScrollPane(Component view, int vsbPolicy, int hsbPolicy)
Creates aJScrollPane
that displays the view component in a viewport whose view position can be controlled with a pair of scrollbars. The scrollbar policies specify when the scrollbars are displayed, For example, ifvsbPolicy
isVERTICAL_SCROLLBAR_AS_NEEDED
then the vertical scrollbar only appears if the view doesn't fit vertically. The available policy settings are listed atJScrollPane.setVerticalScrollBarPolicy(int)
andJScrollPane.setHorizontalScrollBarPolicy(int)
.- Parameters:
view
- the component to display in the scrollpanes viewportvsbPolicy
- an integer that specifies the vertical scrollbar policyhsbPolicy
- an integer that specifies the horizontal scrollbar policy- See Also:
JScrollPane.setViewportView(java.awt.Component)
-
MinimalScrollPane
public MinimalScrollPane(Component view)
Creates aJScrollPane
that displays the contents of the specified component, where both horizontal and vertical scrollbars appear whenever the component's contents are larger than the view.- Parameters:
view
- the component to display in the scrollpane's viewport- See Also:
JScrollPane.setViewportView(java.awt.Component)
-
MinimalScrollPane
public MinimalScrollPane(int vsbPolicy, int hsbPolicy)
Creates an empty (no viewport view)JScrollPane
with specified scrollbar policies. The available policy settings are listed atJScrollPane.setVerticalScrollBarPolicy(int)
andJScrollPane.setHorizontalScrollBarPolicy(int)
.- Parameters:
vsbPolicy
- an integer that specifies the vertical scrollbar policyhsbPolicy
- an integer that specifies the horizontal scrollbar policy- See Also:
JScrollPane.setViewportView(java.awt.Component)
-
MinimalScrollPane
public MinimalScrollPane()
Creates an empty (no viewport view)JScrollPane
where both horizontal and vertical scrollbars appear when needed.

getPreferredSize
public Dimension getPreferredSize()
If thepreferredSize
has been set to a non-null
value just returns it. If the UI delegate'sgetPreferredSize
method returns a nonnull
value then return that; otherwise defer to the component's layout manager.- Overrides:
getPreferredSize
in classJComponent
- Returns:
- the value of the
preferredSize
property - See Also:
