Description
TToggledCheckboxEvent specifies an event handler signalled when
the value in CheckBox-style cell is changed in a grid. Arguments passed to
the event handler identify the grid control for the event notification, the
row and column numbers for the altered cell, and the state for a check box
cell editor.
TToggledCheckboxEvent is the type used to implement the
OnCheckboxToggled in
TCustomGrid and descendent
classes. Applications must implement an object procedure using the signature
for the event handler to respond to the event notification.
