NAME
Tk::Table - Scrollable 2 dimensional table of Tk widgets
SYNOPSIS
use Tk::Table;
$table = $parent->Table(-rows => number,
-columns => number,
-scrollbars => anchor,
-fixedrows => number,
-fixedcolumns => number,
-takefocus => boolean);
$widget = $table->Button(...);
$old = $table->put($row,$col,$widget);
$old = $table->put($row,$col,"Text"); # simple Label
$widget = $table->get($row,$col);
$cols = $table->totalColumns;
$rows = $table->totalRows;
$table->see($widget);
$table->see($row,$col);
($row,$col) = $table->Posn($widget);
DESCRIPTION
Tk::Table is an all-perl widget/geometry manager which allows a two dimensional table of arbitary perl/Tk widgets to be displayed.
Entries in the Table are simply ordinary perl/Tk widgets. They should be created with the Table as their parent. Widgets are positioned in the table using:
$table->put($row,$col,$widget)
If $widget is not a reference it is treated as a string, and a Lable widget is created with the string as its text.
All the widgets in each column are set to the same width - the requested width of the widest widget in the column. Likewise, all the widgets in each row are set to the same height - the requested height of the tallest widget in the column.
A number of rows and/or columns can be marked as 'fixed' - and so can serve as 'headings' for the remainder the rows which are scrollable.
The requested size of the table as a whole is such that the number of rows specified by -rows (default 10), and number of columns specified by -columns (default 10) can be displayed.
If the Table is told it can take the keyboard focus then cursor and scroll keys scroll the displayed widgets.
-scrollbars
. By default, scrollbars will be added nw
. To disable scrollbars, set -scrollbars
to an empty string:
$table = $parent->Table(-scrollbars => '', ...);
The table can be emptied using
$table->clear
the widgets which were in the table are destroyed.
The Tk::Table widget is derived from a Tk::Frame, so inherits all its configure options.
The default focus traversal is giving the focus only to the table widget as a whole. To enable focus traversal into table cells (e.g. if there are embedded entry widgets), then the option -takefocus
has to be set to 0
.
BUGS / Snags / Possible enhancements
Very large Tables consume a lot of X windows.
No equivalent of pack's -anchor/-pad etc. options
