"lineVisible"

Forces that a specific line of the table remains in the visible table area.

Synopsis

setValue(string shape, "lineVisible", int n);

getValue(string shape, "lineVisible", int &n);

shape.lineVisible(int n);

Parameters


Parameter	Description
shape	Name of the object
n	Line index, starting at 0

Description

Forces that a specific line of the table remains in the visible table area. Using this attribute you can move the focus in a table window to force the specific line to be visible. I.e. if using "appendLines" new lines were added to the table, you can set n = 1 to display the table area with the line 2 on the top. If n = -1 has been set, then it will be scrolled to the last line in the table. This does not work in the stopped mode.
