Tk::Pane provides a scrollable frame widget. Once created it can be
treated as a frame, except it is scrollable.
OPTIONS
-gridded => direction
Specifies if the top and left edges of the pane should snap to a
grid column. This option is only useful if the widgets in the pane
are managed by the grid geometry manager. Possible values are
x, y and xy.
-sticky => style
If Pane is larger than its requested dimensions, this option may be used to
position (or stretch) the slave within its cavity. Style is a string that
contains zero or more of the characters n, s, e or w. The string can optionally
contains spaces or commas, but they are ignored. Each letter refers to a side
(north, south, east, or west) that the slave will ``stick'' to. If both n and s
(or e and w) are specified, the slave will be stretched to fill the entire
height (or width) of its cavity.
METHODS
$pane->see($widget ?,options?)
Adjusts the view so that $widget is visable. Aditional parameters in
options-value pairs can be passed, each option-value pair must be
one of the following
-anchor => anchor
Specifies how to make the widget visable. If not given then as much of
the widget as possible is made visable.
Possible values are n, s, w, e, nw, ne, sw and se.
This will cause an edge on the widget to be aligned with the corresponding
edge on the pane. for example nw will cause the top left of the widget
to be placed at the top left of the pane. s will cause the bottom of the
widget to be placed at the bottom of the pane, and as much of the widget
as possible made visable in the x direction.
$pane->xview
Returns a list containing two elements, both of which are real fractions
between 0 and 1. The first element gives the position of the left of the
window, relative to the Pane as a whole (0.5 means it is halfway through the
Pane, for example). The second element gives the position of the right of the
window, relative to the Pane as a whole.
$pane->xview($widget)
Adjusts the view in the window so that widget is displayed at the left of
the window.
$pane->xview(moveto => fraction)
Adjusts the view in the window so that fraction of the total width of the
Pane is off-screen to the left. fraction must be a fraction between 0 and 1.
$pane->xview(scroll => number, what)
This command shifts the view in the window left or right according to number
and what. Number must be an integer. What must be either units or
pages or an abbreviation of one of these. If what is units, the view
adjusts left or right by number*10 screen units on the display; if it is
pages then the view adjusts by number screenfuls. If number is negative then
widgets farther to the left become visible; if it is positive then widgets
farther to the right become visible.
$pane->yview
Returns a list containing two elements, both of which are real fractions
between 0 and 1. The first element gives the position of the top of the
window, relative to the Pane as a whole (0.5 means it is halfway through the
Pane, for example). The second element gives the position of the bottom of the
window, relative to the Pane as a whole.
$pane->yview($widget)
Adjusts the view in the window so that widget is displayed at the top of the
window.
$pane->yview(moveto => fraction)
Adjusts the view in the window so that fraction of the total width of the
Pane is off-screen to the top. fraction must be a fraction between 0 and 1.
$pane->yview(scroll => number, what)
This command shifts the view in the window up or down according to number
and what. Number must be an integer. What must be either units or
pages or an abbreviation of one of these. If what is units, the view
adjusts up or down by number*10 screen units on the display; if it is
pages then the view adjusts by number screenfuls. If number is negative then
widgets farther up become visible; if it is positive then widgets farther down
become visible.
