Constructor Detail

JUScrollBarBinding

public JUScrollBarBinding(javax.swing.JScrollBar sb,
                          JUIteratorBinding iterBinding,
                          boolean scrollCurrRow,
                          boolean deferAssignValues,
                          boolean useEstRC)

Binds a JScrollBar control to a BC4J ViewObject such that JScrollBar can be used to navigate rows in the ViewObject. Optionally an application can control the scrolling of current row into the current range of rows and using estimated row count apis to calculate the maximum row count for the display.

Parameters:

formBinding - The containing JUPanelBinding in which the given iterator binding would be found/created.

sb - JScrollBar control to bind a BC4J ViewObject with.

iterBinding - An iterator Binding that this control is associated with.

scrollCurrentRow - when true, scrolls the current row into the current range of the ViewObject.

deferAssignValues - when true, defers the assignement of JScrollBar values till the ViewObject query is executed

useEstRC - when true, uses getEstimatedRowCount() to calculate the max value for the control.
