## click-must-be-on-gadget

Arguments: grid-column

This is a property of the classes `check-box-column-mixin` and `combo-box-column-mixin`, which implement pseudo-controls in `grid-widget` columns. When set to true, the user must click on the small gadget within the cell in order to activate it by clicking. When `nil`, the user can click anywhere in the interior of the cell. (Pressing the spacebar or return key will still activate the gadget regardless of the value of this property.)

The default is true. The advantage of having this property on is that the user can click in the cell to simply give it the keyboard focus, without changing the value or showing a list of choices. The disadvantage is that the clickable area is smaller.
