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

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 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.

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.
