DX

Size of the horizontal scrollbar's thumbnail in any unit.

Value

Any floating-point value greater than zero and smaller than the difference between XMAX and XMIN.

Default:: "0.1".

Notes

LINEX, XMAX and XMIN are only updated in the scrollbar when DX is updated.

When the canvas is visible, a change in DX can generate a redraw in the horizontal scrollbar on the screen. But it may generate a RESIZE_CB callback event if XAUTOHIDE=Yes.

A change in these values can affect the attribute POSX.
