* The KColorEditDoc class provides a document object that can be used in conjunction with the classes KColorEditApp and KColorEditView
|
|
* to create a document-view model for standard TDE applications based on TDEApplication and TDEMainWindow. Thereby, the document object
|

* is created by the KColorEditApp instance and contains the document structure with the according methods for manipulation of the document
|
|
* data by KColorEditView objects. Also, KColorEditDoc contains the methods for serialization of the document data from and to files.
