## widget-column-mixin

The superclass of all of the `grid-column` mixin classes that implement the several types of built-in cell widgets. The particular subclasses that may be mixed with a `grid-column` class are:

- `check-box-column-mixin`
- `combo-box-column-mixin`
- `editable-text-column-mixin`
- `static-text-and-button-column-mixin`
- `static-text-column-mixin`
- `pixmap-column-mixin`
- `lamp-column-mixin`

If a cell lies at the intersection of a `widget-column-mixin` grid-column and a `widget-row-mixin` grid-row, then one of the built-in cell widgets will appear in that cell. Refer to the particular `widget-column-mixin` subclasses for more information.

A quicker but less object-oriented way to use the built-in cell widgets is to write cell-widget methods. That technique allows adding the built-in widgets to arbitrary cells rather than only to special columns for each type of widget.
