UnitsPerLine property for PowerScript controls
Controls
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.
Usage
In a painter
To set the UnitsPerLine property:
-
Enter the desired number of PowerBuilder
units in the UnitsPerLine field on the Scroll tab page of the window’s
Properties view.
In scripts
The UnitsPerLine property takes an integer value.
