Tk::Pane - A window panner
use Tk::Pane;
$pane = $mw->Scrolled("Pane", Name => 'fred',
-scrollbars => 'soe',
-sticky => 'we',
-gridded => 'y'
);
$pane->Frame;
$pane->pack;
Tk::Pane provides a scrollable frame widget. Once created
it can be treated as a frame, except it is scrollable.
- -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.
- $pane->see($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.
