   "Description" : "This demo is the result of the project explained in the wiki tutorial \"Writing a mini spreadsheet application\" (http://wiki.lazarus.freepascal.org/FPSpreadsheet_tutorial:_Writing_a_mini_spreadsheet_application).

An extended version of this demo is the \"spready\" project which can be found in the \"applications\" folder of the \"Lazarus Components and Code Repository\".

FPSpreadsheetControls are a set of visual components which facilitate creation of a spreadsheet application.

TsWorkbookSource is the base of the package: it links the visual components to a workbook instance and its worksheets and cells.

TsWorkbookTabControl is a TabControl which displays tabs for each worksheet of the workbook. Changing the active tab selects the corresponding worksheet.

TsWorksheetGrid is a grid component which displays the contents of a worksheet. It communicates with the TsWorkbookSource by receiving and sending messages on the selected cell.

TsCellEdit is a multi-line edit control (memo) for entering cell values and formulas. Pressing ENTER transfers the current text into the worksheet.

TsCellIndicator is a simple edit used to display the address of the currently selected cell. Editing the text allows to jump to the cell address.

TsSpreadsheetInspector is a StringGrid (ValueListEditor, to be precise) which displays details on the workbook, the selected worksheet, and the selected cell values and properties.

Linking these controls to a TsWorkbookSource results in a working spreadsheet application without writing any line of code."}
