Methods | |
yview (`moveto', fraction) | xview, yview come in two forms. If the first argument is "moveto," then the widget is instructed to change its view in a way that fraction represents the topmost (or leftmost, in the case of xview) line or pixel. |
yview(`scroll', number, what) (similarly for xview) | This instructs the widget to adjust the view in the window up or down according to number of increments. what specifies whether these increments are in units or pages. If what is units, then it is in terms of the increment properties shown above. |
