UnitsPerLine
property for PowerScript controls
Applies to
Windows, user objects
Description
UnitsPerLine specifies the number of PowerBuilder units you want to
scroll up or down when the user clicks the up or down arrow in the
vertical scroll bar in a window or user object. The default is 0 (1/100 of
the window or user object height). When UnitsPerLine is 0, PowerBuilder
controls vertical scrolling automatically.
PowerBuilder multiplies UnitsPerPage by UnitsPerLine to determine
the number of PowerBuilder units to scroll the window or user object
vertically when the user clicks in the scroll bar.
For information on calculating LinesPerPage and UnitsPerLine, see
Scrolling in windows and user
objects.
Usage note
To control horizontal scrolling in a window or user object, use
the UnitsPerColumn and ColumnsPerPage properties.
