tk::pane(3)
NAME
Tk::Pane - A window panner
SYNOPSIS
use Tk::Pane;
$pane = $mw->Scrolled(Pane, Name => 'fred',
-scrollbars => 'soe',
-sticky => 'we',
-gridded => 'y'
);
$pane->Frame;
$pane->pack;
DESCRIPTION
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 geome
try 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 possi
ble 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 wid
get 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, rela
tive 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, rela
tive to the Pane as a whole. - $pane->xview($widget)
- Adjusts the view in the window so that widget is dis
played 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 wid
gets farther to the left become visible; if it is pos
itive then widgets farther to the right become visi
ble. - $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, rela
tive to the Pane as a whole. - $pane->yview($widget)
- Adjusts the view in the window so that widget is dis
played 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 inte ger. What must be either units or pages or an abbrevi ation 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 num
ber screenfuls. If number is negative then widgets
farther up become visible; if it is positive then wid
gets farther down become visible.
