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);
DESCRIPTIONTk::Table is an all-perl widget/geometry manager which allows a two
dimensional table of arbitrary 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.
The Table will create and manage its own scrollbars if requested via
-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
