Method create

GTK2.Adjustment GTK2.Adjustment(float|mapping value_or_props, float|void lower, float|void upper, float|void step_increment, float|void page_increment, float|void page_size)

Description

The value argument is the initial value you want to give to the adjustment, usually corresponding to the topmost or leftmost position of an adjustable widget. The lower argument specifies the lowest value which the adjustment can hold. The step_increment argument specifies the "smaller" of the two increments by which the user can change the value, while the page_increment is the "larger" one. The page_size argument usually corresponds somehow to the visible area of a panning widget. The upper argument is used to represent the bottom most or right most coordinate in a panning widget's child. Therefore it is not always the largest number that value can take, since the page_size of such widgets is usually non-zero.

All values are optional, they default to 0.0. For most widgets the unit is pixels.
