Uses of JViewport in javax.swing

Fields in javax.swing declared as JViewport
Modifier and Type	Field	Description
`protected JViewport`	ScrollPaneLayout.`colHead`	The column header child.
`protected JViewport`	JScrollPane.`columnHeader`	The column header child.
`protected JViewport`	ScrollPaneLayout.`rowHead`	The row header child.
`protected JViewport`	JScrollPane.`rowHeader`	The row header child.
`protected JViewport`	JScrollPane.`viewport`	The scrollpane's viewport child.
`protected JViewport`	ScrollPaneLayout.`viewport`	The scrollpane's viewport child.
`protected JViewport`	JScrollPane.AccessibleJScrollPane.`viewPort`	this `JScrollPane`'s current `JViewport`

Methods in javax.swing that return JViewport
Modifier and Type	Method	Description
`protected JViewport`	JScrollPane.`createViewport()`	Returns a new `JViewport` by default.
`JViewport`	JScrollPane.`getColumnHeader()`	Returns the column header.
`JViewport`	ScrollPaneLayout.`getColumnHeader()`	Returns the `JViewport` object that is the column header.
`JViewport`	JScrollPane.`getRowHeader()`	Returns the row header.
`JViewport`	ScrollPaneLayout.`getRowHeader()`	Returns the `JViewport` object that is the row header.
`JViewport`	JScrollPane.`getViewport()`	Returns the current `JViewport`.
`JViewport`	ScrollPaneLayout.`getViewport()`	Returns the `JViewport` object that displays the scrollable contents.

Methods in javax.swing with parameters of type JViewport
Modifier and Type	Method	Description
`static Component`	SwingUtilities.`getUnwrappedView(JViewport viewport)`	Returns the first `JViewport`'s descendant which is not an instance of `JLayer`.
`void`	JScrollPane.`setColumnHeader(JViewport columnHeader)`	Removes the old columnHeader, if it exists; if the new columnHeader isn't `null`, syncs the x coordinate of its viewPosition with the viewport (if there is one) and then adds it to the scroll pane.
`void`	JScrollPane.`setRowHeader(JViewport rowHeader)`	Removes the old rowHeader, if it exists; if the new rowHeader isn't `null`, syncs the y coordinate of its viewPosition with the viewport (if there is one) and then adds it to the scroll pane.
`void`	JScrollPane.`setViewport(JViewport viewport)`	Removes the old viewport (if there is one); forces the viewPosition of the new viewport to be in the +x,+y quadrant; syncs up the row and column headers (if there are any) with the new viewport; and finally syncs the scrollbars and headers with the new viewport.
