Tool Events
The MapInfo.Tools namespace supports tool events with information and the ability to cancel the
tool’s operation. A Select Tool’s event lists the items being selected or deselected. Events can be
fired at every stage of use of a particular tool. In your code you can trap certain moments in the
lifecycle of the usage of a tool. Adding code to particular events gives you the maximum flexibility on
customizing the use of each tool in your mapping application.
The events in the namespace are as follows:
FeatureAddingEventArgs This event is fired when an add tool is about to draw
an object.
FeatureAddedEventArgs This event is fired when an add tool has added an
object to a table and map.
FeatureSelectingEventArgs This event is fired when a selection tool is about to
change the selection.
FeatureSelectedEventArgs This event is fired when a selection tool changes the
selection.
FeatureChangingEventArgs This event is fired when a selection tool is about to
change a feature. Use this event to check to see if
the change that is going to happen is valid.
FeatureChangedEventArgs This event is fired after a selection tool changed a
feature.
NodeChangedEventArgs This event is fired when a selection tool alters the
nodes in a selection.
NodeChangingEventArgs Fired when a selection tool is about to change a
node of a selected feature. Use this event to check

ToolActivatedEventArgs This event is fired when a mouse tool is activated.
