DESCRIPTIONTk::TableMatrix::SpreadsheetHideRows is a
Tk::TableMatrix::Spreadsheet-derived widget that implements a
Spreadsheet-like display of tabular information, where some of the rows
in the table can be expanded/hidden by clicking a '+/-' selector in the
row. This can be used to display top-level information in a table,
while allowing the user to expand certain table rows to view detail-
level information.
See demos/SpreadsheetHideRows in the source distribution for a simple
example of this widget
Widget-specific Options
In addition the standard Tk::TableMatrix widget options. The following
options are implemented:
-selectorCol
Column number where the +/- selector will appear. Clicking on the +/-
selector will expand/hide the detail information in the table for a
particular row.
-selectorColWidth
Width of the column used to display the +/- selector. Defaults to 2
-expandData
Hash ref defining the detail-level data displayed when a row is
expanded (by clicking the +/- selector). This hash ref should have the
following structure:
$expandData = {
row1 => { tag => 'detailDataTag',
data => $detailData,
spans=> $spanData,
expandData => $subLevelData
},
row2 => {
.
.
}
Where:
row1, row2, ... Row numbers that will be expandable.
tag => 'detailDataTag' Tag name that will be applied to the detail data.
(optional)
$detailData 2D Array of detail-data to be displayed when
the row is expanded.
e.g. [ [ r1c1, r1c2, r1c3 ],
[ r2c1, r2c2, r2,c3] ]
$spans 1D array of span information (optional) to be
used for display of the detail information.
e.g. [ col2 => "rows,cols", col4 => "rows,cols", ... ]
$subLevelData Optional Recursive expandData used to hold detail-data of detail-data.
MEMBER DATA
The following items are stored as member data
defaultCursor
Name of the mouse cursor pointer that is used for normal (i.e. non-
title, non-indicator) cells in the widget. This is set to the value
of the $widget->cget(-cursor) option when the widget is created.
indRowCols
Hash ref of Row/Cols indexes where there are indicators stores. This
is a quick lookup hash built from _expandData.
_expandData
Internal version of the expandData hash. Any sub-detail data (i.e.
expand data that is at lower levels of expandData) that is visible is
placed at the top level of this hash, for keeping track of the visible
expandData.
Widget Methods
In addition the standard Tk::TableMatrix widget method. The following
methods are implemented:
showDetail
Shows (i.e. expands the table) the detail data for a given row. This
method is called when a user clicks on an indicator that is not already
expanded.
Usage:
$widget->showDetail($row);
# Shows the detail data for row number $row
hideDetail
Hides the detail data for a given row. This method is called when a
user clicks on an indicator that is already expanded.
Usage:
$widget->hideDetail($row);
# Hides the detail data for row number $row
