The Class Browser is designed to display and edit UBIK^® objects in a hierarchical manner. It is also meant to be the superior of all other controls and the only one where at least one instance of it is actually mandatory in a UBIK^® Studio session. So it can be considered as the root of object manipulation in UBIK^®.

In addition, it makes use of Namespaces and uses them for structuring the displayed objects even further.

Basics

Appearance

Icons

Depending on the current view style, the control display different types of UBIK^® classes. Each major class type is by default associated with an unique icon, in order to provide a visual distinction of the class types. However, these icons can be replaced by more specific ones during the customization process, which means that it is not a reliable indicator if an object is of a certain type.

The coloring of an icon indicates another object status: if the icon appears grey instead of its regular coloring, the respective object is considered as a system object.

A blue triangle in the upper left corner of an icon indicates that the object is an instance of another object in the same view.

Tooltips

Hovering with the mouse over a tree node will bring up a Tooltip-Text, showing you the system type of the respective object and if it is currently in Live- or in Sandbox-mode. Depending on the actual type of the object, there will be additional information presented in the Tooltip.

Node styles

a bold node text means that the corresponding UBIK^® object is changed, yet unsaved
a ~~strikethrough~~ node text means that the corresponding UBIK^® object was deleted somewhere outside of this control. Once you refresh the node, i.e. by collapsing and expanding its parent node, it will disappear
an italic node text means that the corresponding {{UBIK} object doesn't derive (or instance, depending on the view mode) directly from the hierachical parent, but is inherited
a gray node text means that the corresponding UBIK^® is locked against modifications
a red node text means that the corresponding UBIK^® object violates one of the rules that were assigned to it

Node texts

The nodes will always display the string representation of the respective object, which is by default

Name Description for MetaClasses
Description (Name) for Content objects

However, as this is something that can be customized, the nodes might display something different.

Drag & Drop

The Class Browser is a source for Drag&Drop operations, any object (with the exception of Namespaces) can be dragged from here.

Toolbar

Item	Purpose
View Style	Indicates or changes the View Style of the control; changing it will result in reloading of the control
Search	Allows to perform a (visual) search through the labels of the tree nodes; found objects will be highlighted accordingly

Context menu

Class Browser context menu

Clicking a node with the right mouse button will bring up a standard context menu for each node, except namespaces. Depending on the view style there will be different options, however, all nodes will at least show the following menu items:

Menu	Object Type	Purpose
Derive new object	MetaClass	Creates a new derivate of the context MetaClass
Navigate To	All	Opens the Navigation menu
Save	All	Saves changes on the object to the database
Delete	All	Deletes the object from cache. It will only be removed from the database after a Save
Start Workflow...	All	Provides all workflows assigned to this object, categorized. Clicking an item will start the workflow and pass the current context object.
Switch Branch To...	MetaClass	Opens a sub menu to transfers a MetaClass including all its sub objects into Live- (=Released) or back into Sandbox-mode (only available for administrator in ViewStyle 'Release State'); System objects and objects already having the target mode will not be affected
Switch to Sandbox Mode/Live Mode	MetaClass	Transfers the MetaClass into Live- (=Released) or back into Sandbox-mode (only available for administrator in ViewStyle 'Release State')

View Styles

Class Browser View Styles

The Class Browser has three different View Styles, each of them providing different views and functionality.

Hierarchical

In this view mode, the Derivates relation from each MetaClass deriving directly or indirectly from BaseClass will be evaluated. It is also the Style where new MetaClasses should be created by deriving from existing ones.

Inheritance

In this view mode, the Inheritance relation of all MetaClasses will be evaluated. So expanding a node will display its inheritance owner below it, which implies that in this view there can only be exactly one node below another.

Content

In this view mode, the Instances of all MetaClasses will be evaluated.

Release State

This view mode is identical to 'Hierarchical'. In Addition to that, single MetaClasses (optionally including all objects in its sub branch) can be transfered into Live Mode (=Released) and also switched back into Sandbox Mode. This view mode is only available for administrators.

A color code visualizes the current release state of each MetaClass:

Color	State	Description
Blue	Sandboxed	This status indicates that the MetaClass is not released, it is in Sandbox Mode
Green	Fully Released	This status indicates that the MetaClass is released and all its relations (forward and backward relations) are released as well
Yellow	Released Except Primary Relations	This status indicates that the Metaclass is released and the data of all backward relations are released, but at least one forward relation is not released yet
Cyan	Released Except Secondary Relations	This status indicates that the Metaclass is released and the data of all forward relations are released, but at least one backward relation is not released yet
Magenta	Released Isolated	This status indicates that the Metaclass is released but the data of at least one forward relation and of at least one backward relation is not released yet
Gray	System Object	This status indicates that the Metaclass is a SystemObject and cannot be changed by the user

Other functionality

Editing name and description of an object

Edit the label of any node (except Namespaces) using F2 and hit ↵ Enter when finished. This will attempt to set the text left of the first blank to the Name property (NAME) of the object, and the text right of the first blank to its Description property (DESCR). If the object doesn't posses the NAME or the DESCR property or it is locked for whatever reason, editing will not be possible.

Bulk editing namespaces

Edit the label of a namespace node using F2 and hit ↵ Enter when finished. This will attempt to set the namespace property (NAMESPACE) of all sub-objects (first level only) to the new value.
