Host implements dependency handling for plugins.
Can be used between host-objects and the Plug-In or inside the Plug-In to handle internal updates!
|
pure virtual |
Install update notification for given object.
It is essential to remove all dependencies again using 'removeDependent'! Dependencies are not removed automatically when the 'object' is released!
| object | : interface to object that sends change notifications |
| dependent | : interface through which the update is passed |
|
pure virtual |
Remove a previously installed dependency.
Inform all dependents, that object has changed.
| object | is the object that has changed |
| message | is a value of enum IDependent::ChangeMessage, usually IDependent::kChanged - can be a private message as well (only known to sender and dependent) |
Same as triggerUpdates, but delivered in idle (usefull to collect updates).
