Tk::Table - Scrollable 2 dimensional table of Tk widgets
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);
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:
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
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
Very large Tables consume a lot of X windows.
No equivalent of pack's -anchor/-pad etc. options
