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.
