Tk::Pane(3pm) perl/Tk Documentation Tk::Pane(3pm)NAMETk::Pane - A window panner
SYNOPSIS
use Tk::Pane;
$pane = $mw->Scrolled("Pane", Name => 'fred',
-scrollbars => 'soe',
-sticky => 'we',
-gridded => 'y'
);
$pane->Frame;
$pane->pack;
DESCRIPTIONTk::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. Additional 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.
