Classes Class XbpBrowse() :panDown()

Method XbpBrowse():panDown() Foundation

Scrolls down one line.

Syntax 
:panDown( [<nRows>] ) --> self
Parameters
<nRows>
<nRows> is a numeric value which specifies the number of lines the visible area is scrolled. This parameter is optional and defaults to 1.
Return

:panDown() returns a reference to the XbpBrowse object.

Description

:panDown() scrolls the visible area of the browse window downwards and reads a new value for the last data row from the data source. If the last data row is already visible, the browse window remains unchanged.

The position of the browse cursor is not changed by :panDown(). Therefore, the code block assigned to the :hitBottomBlock instance variable is not evaluated when scrolling reaches the bottom of the display.

The changes applied by the :panDown() method will not be visible until the browse is stabilized. Use :forceStable() to make the changes become visible immediately.
