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 use estimated row count APIs to calculate the maximum row count for the display.

Parameters:
sb - JScrollBar control with which to bind a BC4J ViewObject.
iterBinding - An iterator Binding with which this control is associated.
deferAssignValues - When true, defers the assignement of JScrollBar values to when the ViewObject query is executed
useEstRC - When true, uses getEstimatedRowCount() to calculate the max value for the control.
Method Detail

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 use estimated row count APIs to calculate the maximum row count for the display.
