Usage
When the user clicks in a vertical scroll bar or presses the down
arrow key with focus in a vertical track bar, nothing happens unless you
have scripts that change the bar’s Position property. For the scroll bar
arrows and arrow keys for the track bar, use the LineUp and LineDown
events; for clicks in the scroll bar or track bar background above and
below the thumb, use the PageUp and PageDown event; for dragging the thumb
itself, use the Moved event.
Examples
This code in the LineDown event causes the thumb to move down when
the user clicks on the down arrow of the vertical scroll bar and displays
the resulting position in the StaticText control st_1:
|
1 2 3 4 5 6 7 |
IF This.Position > This.MaxPosition - 1 THEN This.Position = MaxPosition ELSE This.Position = This.Position + 1 END IF st_1.Text = "LineDown " + String(This.Position) |
