Comments to Revision 1089

The revision 1089 contains a set of changes:

A new TreeViev-Control

If the user selects a tree view node and then changes to any other control of a dialog (tree view will lost its focus in this case) the selected node becomes indistinguishable to the other nodes. This situation is something difficult because the user has no orientation about the node he is dealing with.

Therefore the TrvTreeView has been added to the project. This tree view inherits System.Windows.Forms.TreeView and adds the functionality of holding a different color for the node selected at last before a LostFocusEvent.

This new tree view has been integrated in the code generation components so that the maximal work you have to do is to run a nant generateWinforms command to use this control.

A new class: CommonNUnitFunctions

A new class has been added to the test sources, the class CommonNUnitFunctions. This class inherits NUnitFormTest and in a new test class you can easily replaces NUnitFormTest against CommonNUnitFunctions.

In this case you will have the use of some internal test functions and the very first one is the standard handler for a message box. Other controls may follow. So it will be a good idea to change or to add a template in SharpDevelope.

Open to discuss: Log-File initialization ...

A new common Exception: CancelSaveException

ICT/Petra/Client/CommonForms/PetraEditForm.cs actually could only handle unspecific Exceptions. In order to be able to cancel a save operaton a CancelSaveException has been added. This Exception is used at different points in the automatic code.

If you want to cancel a save operation then

1. Generate a proper and clear error message
2. Create a defined state for the data
3. Throw a CancelSaveException
