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 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.
