The minimum value of the adjustment.
Default value: 0
page-increment
The page-increment property of type :double (Read / Write)
The page increment of the adjustment.
Default value: 0
page-size
The page-size property of type :double (Read / Write)

Default value: 0
step-increment
The step-increment property of type :double (Read / Write)
The step increment of the adjustment.
Default value: 0
upper

Details

The gtk-adjustment object represents a value which has an associated lower and upper bound, together with step and page increments, and a page size. It is used within several GTK+ widgets, including gtk-spin-button, gtk-viewport, and gtk-range, which is a base class for gtk-scrollbar, and gtk-scale.

The gtk-adjustment object does not update the value itself. Instead it is left up to the owner of the gtk-adjustment to control the value.
