Immediately under the button bar is the data entry area. This is a small area, which contains a current cell indicator, a confirm and a cancel button, and an entry area for detailed editing of the cell contents. See Figure 1-3
On the far left of the Data Entry area is the current cell indicator area. If a single cell is selected, it will show the address for the cell. If a region is selected, it shows the size of the region in the format:
4Lx5C
Where L is the number of rows and C is the number of columns. In the example above, this would be a selection of 4 rows by 5 columns.
While entering data in the entry area, you can confirm the
current cell contents by pressing the green return button
.
If a user decides that the data entered into a cell is
not what they want, the Cancel button will cancel the current
data and return the cell to the state it was at before. The
data being entered into the cell can be canceled by pressing
the red X button
.
The most common use of this is when overwriting the contents of a cell with new data. If the user decided to revert the change before confirming it, the cancel button is the answer.
Most of the work done on a spreadsheet is done to the main Cell area, the large grid like part of the worksheet. This is where all the formulas and data are entered, and is the center of activity for the spreadsheet.
The sheet is bordered by a column label and a row label. Columns are labeled alphabetically and are labeled horizontally across the top of the sheet. See Figure 1-5. Rows are labeled vertically along size the left side of the sheet and are sorted numerically. See Figure 1-6
The section at the very bottom of the worksheet view is the info area. It contains information about the currently selected cells. This is also where the sheet indicator lives.
To the left side is the sheet indicator. In workbooks where there are more than one sheet, this indicates how many sheets are there, and also allows the user to move to another sheet by clicking the proper tag. This is not implemented yet.
In the bottom right hand corner, is an info area that shows some constantly calculated values. The default set is to show the Sum of all the currently selected cells.
There is a right click option that includes a few more options. This can include Sum, Min, Max, Average, Count.
