Spreadsheet: Add undo/redo implementation
The Spreadsheet application currently does not support undo/redo, and with this update, we are starting the process of adding this feature :-) Additionally, the save dialog has been updated to use GUI::MessageBox::ask_about_unsaved_changes() for system cohesity. Spreadsheet: Add basic undo functinoality The spreadsheet application now has basic support for undo. Testing of this feature is limited, and may not work as intended yet. Spreadsheet: Add callback when a cell's value is changed In addition to the callback being added, this commit also exposes the SheetModel class via a getter in SpreadSheetView. Spreadsheet: Remove debug statements and use cell change callback This commit uses the on_cell_data_change callback from within the SheetModel class. This allows for us to push/pop changes to the undo stack. With this, we have basic Undo/Redo functionality :-) Spreadsheet: Actually add window::set_modified Spreadsheet: Const-correctness :-) Spreadsheet: Reorder the edit menu actions
