Main working principles in edit windows
An introduction to the main function principles of the edit windows.
Three buttons do control the window:
- [Apply]
- [OK]
- [Cancel]

By pressing [Apply] two things happen:
- The edit window itself is updated.
- The data is "sent back" to the main application. This means the main applcation and other edit windows will be updated as well.
If you press [OK] two things happen as well:
- The data is "sent back" to the main application. This means the main applcation and other edit windows will be updated.
- The edit window itself will be closed afterwards.
[Cancel] does just close the Edit window. All changes since the last [Apply] button press will be lost!
