## Uses of Class
javax.swing.JViewport

Packages that use JViewport
javax.swing | Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms.

Uses of JViewport in javax.swing

Fields in javax.swing declared as JViewport
`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`

Methods in javax.swing that return JViewport
`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
`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.
