They should +be created with the Table as their parent. Widgets are positioned in the +table using: + + $table->put($row,$col,$widget) + +If I<$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 C<-takefocus> has +to be set to C<0>. + +=head1 BUGS / Snags / Possible enhancements + +=over 4 + +=item * + +Very large Tables consume a lot of X windows. + +=item * + +No equivalent of pack's -anchor/-pad etc. options + +=back + +=head1 SEE ALSO + +L<Tk::grid>, L<Tk::HList>, L<Tk::TableMatrix>, L<Tk::MListbox>, +L<Tk::Columns> + +=cut + |
