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.
