int EZ_SetVScrollbarDiscreteSpeed(EZ_Widget *widget, int speed)
ARGUMENTS
widget Specifies a scrollbar widget, a text-widget, a
listbox, a fancy-listbox, a tree-widget or a work-area
widget.
speed Specifies a positive integer.
DESCRIPTION
EZ_SetHScrollbarDiscreteSpeed sets the discrete scrolling
speed of the horizontal scrollbar on the specified compos-
ite widget. The discrete scrolling speed is used when the
arrow button on the scrollbar is pressed or one of the
relevent arrow keys is pressed while the scrollbar is in
focus.
EZ_SetVScrollbarDiscreteSpeed sets the discrete scrolling
speed of the vertical scrollbar on the specified composite
widget.
The default discrete scrolling speed is 1. The interpreta-
tion of this speed depends on the context. For internal
widgets that use scrollbars, the meaning is following: for
TextWidget and ListBox, the scrolling unit is the height
of a text line; for Fancy ListBox, TreeWidget, WorkArea,
the scrolling unit is one pixel.
This function returns the current discrete scrolling speed
of the scrollbar.
