LinesPerPage property for PowerScript controls
Controls
User objects and windows
Description
The LinesPerPage property determines the number of lines on
a page for scrolling purposes. PowerBuilder multiplies Units Per
Line by Lines Per Page to determine the number of PowerBuilder units
to scroll the window vertically when the user clicks in the scroll
bar. For information on calculating LinesPerPage and UnitsPerLine,
see “Scrolling in windows and
user objects”.
To control the horizontal scroll bar in a window or user object,
use the UnitsPerColumn and ColumnsPerPage properties.
Usage
In a painter
To set the LinesPerPage property:
-
Enter the desired number (between 1 and
100) in the Lines Per Page option on the Scroll tab page of the
window’s Properties view.
In scripts
The LinesPerPage property takes an integer value between 1
and 100. The following line sets LinesPerPage for a window to 20:
