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. 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. BUGS
/ Snags / Possible enhancements o Very large Tables consume a lot of X windows. o No equivalent of pack's -anchor/-pad etc. options SEE ALSO

Template::Plugin::Table - Plugin to present data in a table SYNOPSIS
[% USE table(list, rows=n, cols=n, overlap=n, pad=0) %] [% FOREACH item IN table.row(n) %] [% item %] [% END %] [% FOREACH item IN table.col(n) %] [% item %] [% END %] [% FOREACH row IN table.rows %] [% FOREACH item IN row %] [% item %] [% END %] [% END %] [% FOREACH col IN table.cols %] [% col.first %] - [% col.last %] ([% col.size %] entries) [% END %] DESCRIPTION
The "Table" plugin allows you to format a list of data items into a virtual table. When you create a "Table" plugin via the "USE" directive, simply pass a list reference as the first parameter and then specify a fixed number of rows or columns. [% USE Table(list, rows=5) %] [% USE table(list, cols=5) %] The "Table" plugin name can also be specified in lower case as shown in the second example above. You can also specify an alternative variable name for the plugin as per regular Template Toolkit syntax. [% USE mydata = table(list, rows=5) %] The plugin then presents a table based view on the data set. The data isn't actually reorganised in any way but is available via the "row()", "col()", "rows()" and "cols()" as if formatted into a simple two dimensional table of "n" rows x "n" columns. So if we had a sample "alphabet" list contained the letters '"a"' to '"z"', the above "USE" directives would create plugins that represented the following views of the alphabet. [% USE table(alphabet, ... %] rows=5 cols=5 a f k p u z a g m s y b g l q v b h n t z c h m r w c i o u d i n s x d j p v e j o t y e k q w f l r x We can request a particular row or column using the "row()" and "col()" methods. [% USE table(alphabet, rows=5) %] [% FOREACH item = table.row(0) %] # [% item %] set to each of [ a f k p u z ] in turn [% END %] [% FOREACH item = table.col(2) %] # [% item %] set to each of [ m n o p q r ] in turn [% END %] Data in rows is returned from left to right, columns from top to bottom. The first row/column is 0. By default, rows or columns that contain empty values will be padded with the undefined value to fill it to the same size as all other rows or columns. For example, the last row (row 4) in the first example would contain the values "[ e j o t y undef ]". The Template Toolkit will safely accept these undefined values and print a empty string. You can also use the IF directive to test if the value is set. [% FOREACH item = table.row(4) %] [% IF item %] Item: [% item %] [% END %] [% END %] You can explicitly disable the "pad" option when creating the plugin to returned shortened rows/columns where the data is empty. [% USE table(alphabet, cols=5, pad=0) %] [% FOREACH item = table.col(4) %] # [% item %] set to each of 'y z' [% END %] The "rows()" method returns all rows/columns in the table as a reference to a list of rows (themselves list references). The "row()" methods when called without any arguments calls "rows()" to return all rows in the table. Ditto for "cols()" and "col()". [% USE table(alphabet, cols=5) %] [% FOREACH row = table.rows %] [% FOREACH item = row %] [% item %] [% END %] [% END %] The Template Toolkit provides the "first", "last" and "size" virtual methods that can be called on list references to return the first/last entry or the number of entries in a list. The following example shows how we might use this to provide an alphabetical index split into 3 even parts. [% USE table(alphabet, cols=3, pad=0) %] [% FOREACH group = table.col %] [ [% group.first %] - [% group.last %] ([% group.size %] letters) ] [% END %] This produces the following output: [ a - i (9 letters) ] [ j - r (9 letters) ] [ s - z (8 letters) ] We can also use the general purpose "join" virtual method which joins the items of the list using the connecting string specified. [% USE table(alphabet, cols=5) %] [% FOREACH row = table.rows %] [% row.join(' - ') %] [% END %] Data in the table is ordered downwards rather than across but can easily be transformed on output. For example, to format our data in 5 columns with data ordered across rather than down, we specify "rows=5" to order the data as such: a f . . b g . c h d i e j and then iterate down through each column (a-e, f-j, etc.) printing the data across. a b c d e f g h i j . . . Example code to do so would be much like the following: [% USE table(alphabet, rows=3) %] [% FOREACH cols = table.cols %] [% FOREACH item = cols %] [% item %] [% END %] [% END %] Output: a b c d e f g h i j . . . In addition to a list reference, the "Table" plugin constructor may be passed a reference to a Template::Iterator object or subclass thereof. The Template::Iterator get_all() method is first called on the iterator to return all remaining items. These are then available via the usual Table interface. [% USE DBI(dsn,user,pass) -%] # query() returns an iterator [% results = DBI.query('SELECT * FROM alphabet ORDER BY letter') %] # pass into Table plugin [% USE table(results, rows=8 overlap=1 pad=0) -%] [% FOREACH row = table.cols -%] [% row.first.letter %] - [% row.last.letter %]: [% row.join(', ') %] [% END %] AUTHOR
