NAME

EZ_DoScroll - move a scrollbar

SYNOPSIS

#include <EZ.h> void EZ_DoScroll( EZ_Widget *scrollbar, int offset, int absolute)

ARGUMENTS

scrollbar specifies a scrollbar widget. offset specifies an offset. absolute specifies how to interpret offset.

DESCRIPTION

A scrollbar uses three state variables to scroll an object: total_size, page_size and start_position (e.g. number of lines, number of lines in one page and the index of the first line currently displayed). EZ_DoScroll scrolls the object which scrollbar controls by the specified offset. If absoulte is True, offset is treated as the absolute position, otherwise, it is inter- preted as the offset from the start_position.
