Purpose Keep same value for corresponding properties
linkprop
Syntax hlink = linkprop(obj_handles,'PropertyName')
hlink = linkprop(obj_handles,{'PropertyName1','PropertyName2',...})
Description Use linkprop to maintain the same values for the corresponding properties of
different objects.
hlink = linkprop(obj_handles,'PropertyName') maintains the same value
for the property PropertyName on all objects whose handles appear in
obj_handles. linkprop returns the link object in hlink. See “Link Object” for
more information.
hlink =
linkprop(obj_handles,{'PropertyName1','PropertyName2',...})
maintains the same respective values for all properties passed as a cell array
on all objects whose handles appear in obj_handles.
Note that the linked properties of all linked objects are updated immediately
when linkprop is called. The first object in the list (obj_handles) determines
the property values for the rest of the objects.
Link Object The mechanism to link the properties of different graphics objects is stored in
the link object, which is returned by linkprop. Therefore, the link object must
exist within the context where you want property linking to occur (such as in
the base workspace if users are to interact with the objects from the command
line or figure tools).
Modifying Link
Object
The following list describes ways to maintain a reference to the link object.
Return the link object as an output argument from a function and keep it in
the base workspace while interacting with the linked objects.
Make the hlink variable global.
Store the hlink variable in an object’s UserData property or in application
data. See the “Examples” section for an example that uses application data.
If you want to change either the graphics objects or the properties that are
linked, you need to use the link object methods designed for that purpose.
