The newly opened tree view document.
The node type of the root object. This must be a plug-in defined type that may correspond to a predefined Natural Studio type.
The key that identifies the object within its type.
Determines the caption of the document window.
In order to generate a caption that matches the caption format used
in Natural Studio document windows, the string passed in this parameter may
contain the format specifier %std
. This format specifier will be
dynamically replaced by an identifier of the root object in the following way:
If the root node corresponds to a predefined Natural Studio object, the format
specifier %std
is replaced by
"name
[library] -". Otherwise the identifier
is built in the form "node-type-caption
display-name -", where
node-type-caption is the caption that was passed
when the node type was created and display-name is
the string passed in DisplayName.
The value specified here is passed back to the plug-in when Natural
Studio later calls the plug-in through the interface
INaturalStudioPlugInTree
in order to retrieve data to fill the view. This enables the plug-in to deliver
different data for the same root object.
The ID of the plug-in that defined the type.
Additional information that a plug-in may want to assign to the
root object. Natural Studio does not interpret this information. It just passes
it back to the plug-in when it later calls the plug-in through the interface
INaturalStudioPlugInTree
in order to retrieve data to fill the view.
The text to be displayed at the root node.
Indicates if the root node has child nodes and shall hence be
displayed with a plus-sign as expandable. A value of 1 means that the root node
has children, -1 that the root node has no children, 0 or not specified means
that the plug-in does not know yet. Natural Studio will then retrieve this
information from the plug-in in a later call through the interface
INaturalStudioPlugInTree
.
If the plug-in already knows not only that the root node has child
nodes, but also already knows the child nodes themselves, it can pass them in
this parameter as a subtree of arbitrary depth. The parameter must then contain
an XML document describing the child nodes. The XML document is structured
according to the DTD defined in
INaturalStudioPlugInTree::GetChildren
.
If this parameter is specified, Natural Studio implicitly assumes that the root
node has child nodes, ignores what is specified in HasChildren and performs no
call through the interface INaturalStudioPlugInTree
to determine if the root node has child nodes.
If the root node corresponds to a predefined Natural Studio object, this property contains the type of the corresponding predefined object.
If the root node corresponds to a predefined Natural Studio object, this property contains the key of the corresponding predefined object.
