TableMatrix::Spreadsheet(3pm)				       perl/Tk Documentation				     TableMatrix::Spreadsheet(3pm)

NAME
Tk::TableMatrix::Spreadsheet - Table Display with Spreadsheet-like bindings. SYNOPSIS
use Tk; use Tk::TableMatrix::Spreadsheet; my $t = $top->Scrolled('Spreadsheet', -rows => 21, -cols => 11, -width => 6, -height => 6, -titlerows => 1, -titlecols => 1, -variable => $arrayVar, -selectmode => 'extended', -titlerows => 1, -titlecols => 1, -bg => 'white', ); DESCRIPTION
Tk::TableMatrix::Spreadsheet is a Tk::TableMatrix-derived widget that implements some bindings so the resulting widget behaves more like a spreadsheet. Bindings Added: o Row/Col resize handles appear when the cursor is placed over a row/col border line in the rol/col title area. Dragging these handles will resize the row or column. If multiple rows or columns are selected, then the new row/col size will apply to all row/cols selected. Note: With the base Tk::TableMatrix, it is possible to resize the row/cols by dragging on any cell border. To be more spreadsheet-like, Tk::TableMatrix::Spreadsheet defaults to enable row/col resizing only thru the title row/col dragging. To override this default behavoir, set the -resizeborder option to 'both' at startup. o A popup menu for row/col insert/delete appears when the mouse is right-clicked in the row/col title areas. o Cells activate (i.e. the contents become edit-able) only when the cell is double-clicked or the F2 button is pressed. The default Tk::TableMatrix behavior is for the cell to be activated when the cell is single-clicked. o The Escape key causes any changes made to a cell to be canceled and the current selection cleared. o The return key causes the the current cell to move down. o The tab (or shift tab) key causes the current cell to be moved to the right (left). o The delete key will delete the current selection, if no cell is currently active. o The Mouse button 2 (middle button) paste from the PRIMARY. (Control-v pastes from the clipboard). Additional Information Widget methods, options, etc, are inherited from the Tk::TableMatrix widget. See its docs for additional information.
