|
* ControlButtons serves only to control the activation of the Ok, Apply, Cancel
|
|
* and Restore buttons on the View dialog.
|
|
*
|
|
* More generally, the class is part of a hierarchy of controller classes
|
|
* that together connect the GUI-dependent dialog to any appropriate
|
|
* signals and dispatches any changes to the kernel.
|
|
*
|
|
* These controllers have no knowledge of the actual instantiation of the
|
|
* GUI-dependent View and ButtonController, which should therefore
|
|
* be created elsewhere.
|
|
*
|
|
* Once created, the Controller will take care of their initialisation,
|
|
* management and, ultimately, destruction.
