Description
The gtk.Scrollbar
widget is an abstract base class for gtk.HScrollbar
and gtk.VScrollbar.
The position of the thumb in a scrollbar is controlled by the scroll
adjustments. The gtk.Scrollbar uses the attributes in an adjustment (see gtk.Adjustment) as follows:
- the
adjustment.lowerattribute is the minimum value of the scroll region - the
adjustment.upperattribute is the maximum value of the scroll region - the
adjustment.valueattribute represents the position of the scrollbar, which must be betweenadjustment.lowerandadjustment.upper-adjustment.page_size - the
adjustment.page_sizeattribute represents the size of the visible scrollable area - the
adjustment.step_incrementattribute is the distance to scroll when the small stepper arrows are clicked - the
adjustment.page_incrementattribute is the distance to scroll when the Page Up or Page Down keys are pressed
