4.4.2 Rows

A column holds a number of rows. Each row comes in four main parts, not all of which are visible for all row values. Rows which represent classes have a pair or up/down arrows to the left of the row name button which you can use to control which parts of the row are visible.

Figure 4.8: Components of a workspace row

Row name button
  Each row has a name. The name is formed from the name of the current column, plus a number.

  If you double-left-click on the row name button, `nip2` will pop up a viewer or dialog box for the value of the row. If you left-click, `nip2` will select that row and deselect all other rows. If you click on an empty space in the workspace, it will deselect all rows. If you Ctrl-left-click, `nip2` will toggle selection of that row. If you select one row and then Shift-left-click on another row in the same column it will select the second row and all the rows in between. If you drag with the left button, you can change the order of rows in a column. Hold down the right mouse button for a useful menu.

Graphic
  If the row's value is a class, and if the class is an instance of one of `nip2`'s graphic classes, then `nip2` will draw a graphic representation of the row's value. See §6.12.2 for a more detailed explanation.

Members
  If the row has a class for a value, then `nip2` will draw a sub-column listing the class members. Subcolumn members are in turn rows themselves.

Text
  Finally, the text part normally shows a text representation of the row's value. If you left-click on the value, it changes to show the formula which generated that value. You can edit the formula and press Return to change it.

  Alternatively, selecting `View` / `Show Formula` toggles the current column between displaying values for objects and displaying the formula.
