TActionClient.ChangesAllowed Property

Indicates which kinds of changes to the action client are permissible.

Pascal
property ChangesAllowed: TChangesAllowedSet;
C++
__property TChangesAllowedSet ChangesAllowed;

Although action clients are part of a customizable user interface, allowing all changes may not necessarily be desirable. Use the ChangesAllowed property to indicate which changes to the action client are allowable. Possible values in the set are:

Value 
Description 
caModify  
The item can be modified internally. For example, the visible caption can be changed.  
caMove  
The item can be relocated on the action band.  
caDelete  
The item can be removed from the action band.  

Note: The property is a set, and can have multiple values at the same time. In fact, the default is to allow all three values (all changes are possible).
