If your window is resizable, it is possible that not all the window's contents will be visible during execution. In such cases, you should make the window scrollable by providing vertical and horizontal scroll bars. You do this on the Scroll property page.
By default, PowerBuilder controls scrolling when scroll bars are present. You can control the amount of scrolling.
To specify window scrolling:
Click the window's background so the Properties view displays window properties.
Select the Scroll tab.
Indicate which scroll bars you want to display by selecting the HScrollBar and VScrollBar check boxes.
Specify scrolling characteristics as follows:

UnitsPerColumn |
The number of PowerBuilder units to scroll right or left when the user clicks the right or left arrow in the horizontal scroll bar. When the value is 0 (the default), it scrolls 1/100 the width of the window. |
ColumnsPerPage |
The number of columns to scroll when the user clicks the horizontal scroll bar itself. When the value is 0 (the default), it scrolls 10 columns. |

The number of lines to scroll when the user clicks the vertical scroll bar itself. When the value is 0 (the default), it scrolls 10 lines. |
