To switch the toolbar display on and off

• From the View menu, choose Toolbar.

  When the toolbar is displayed in the main application window, a check mark is shown next to this menu command.

Navigation Tree

The navigation tree on the left side of the main application window shows databases of Tamino XML Servers to which you have previously connected. When you invoke the Tamino X-Plorer for the first time, the list is empty. See Connecting to a Tamino Database for further information.

You can expand or collapse the tree structure by clicking the plus or minus sign in front of an object. When using the keyboard, select the object and press RIGHT-ARROW or LEFT-ARROW.

When you select an object, details about this object are displayed in the Content pane and in the Properties pane, but the tree is not expanded.

A database contains collections (the largest units of information within a database). A collection contains one group of schemas. For each schema containing a doctype, the collection contains one group of instances of that doctype. The following example shows different doctypes of schemas and the corresponding groups of instances.

The object types are indicated by the following icons:

	Server
	Connected database
	Disconnected database
	TSD3 or TSD4 collection
	TSD2 collection
	WebDAV-enabled collection
	Group of schemas
	TSD3 or TSD4 schema
	TSD2 schema
	Doctype of XML schema
	Doctype of non-XML schema
	Group of XML instances
	Group of non-XML instances
	Group of XML instances without doctype (grouped by root element name)
	Group of non-XML instances without doctype (grouped by root element name)
	Group of instances with active filter
	XML instance
	Non-XML instance
	XML instance without doctype
	Non-XML instance without doctype

For information on TSD4, TSD3 and TSD2, see Collections.

Arrows for browsing the instances may appear in the tree. See Handling Very Large Amounts of Data.

Context Menus

Context menus are available for the entries in the navigation tree. For example, the following context menu is available for a group of instances:

Additionally, two commands (Next and Last) appear when the selected node is expanded so that instances are shown and not all instances can be shown at the same time. Depending on the pack of instances that is currently shown (see Handling Very Large Amounts of Data), you can either display the next or last pack or the previous or first pack.

To invoke a context menu

1. Select the object for which you want to invoke a context menu.

2. Click the right mouse button.

   Or:
   Press SHIFT+F10.

   The context menu appears and you can now choose the required command.

Content Pane

The Content pane at the top right of the main application window shows the content of the XML object that is currently selected in the navigation tree.

Non-XML instances in the following formats can also be shown in the Content pane: GIF, JPG, HTML, SVG and ASCII text.

Restrictions:

• Objects in the HTML format
  Under certain circumstances, the Content pane remains empty in HTML view (for example, HTML pages based on frames or documents that contain external references such as images).

• Right-to-left orientation
  Documents with right-to-left orientation or mixed orientation may not be displayed in the correct sequence.

• SVG Includes
  In case an SVG document internally refers to another content, which is not accessible in URL form. Displaying such a document would not be possible for the SVG view.

• SVG DTD Reference
  Should an SVG document refer to a DTD or include entity declarations, such a document cannot be added to Tamino as an XML object (as Tamino does not support DTDs). However, it is possible to add this document as a non-XML document.

• SVG External Links and References
  If an SVG document (that has been added to Tamino as a non-XML object) has DTD or link references to an external URL, and this URL is not accessible or is beyond proxy, the SVG content is rendered under default environment settings. However, this may cause the SVG not to be rendered at all, or to be rendered with an incorrect dimension (size).

Help:

• SVG Context Help
  Right-clicking on the SVG Image view opens a context help that can be referred to while working with the content.

When information cannot be displayed in the Content pane or when no information is available, a hint is provided. For example, for a group of instances, no content information is available. In this case, the Content pane informs you to check the Properties pane.

Depending on the type of object, one or more views are available. When different views are available, they can be activated using the following buttons in the top right corner of the Content pane:

Button	Keyboard	Description
	CTRL+SHIFT+T	Tree view for XML objects. Not available for non-XML instances. Whether lines are wrapped in tree view depends on the corresponding setting in the Options dialog box. See Setting the Tamino X-Plorer and X-Query Options for further information.
	CTRL+SHIFT+P	Plain view providing the XML code of an XML object. Or plain view providing the HTML code of an HTML document
	CTRL+SHIFT+H	Browser-like view for HTML documents with the restrictions described above.
	CTRL+SHIFT+I	Image view for non-XML objects (for example, GIF).
	CTRL+SHIFT+X	Hexadecimal view for non-XML objects of media type "text/plain".
	CTRL+SHIFT+S	SVG image view for Scalable Vector Graphics

The following example shows the tree view for an XML instance:

The following example shows the plain view for the same instance:

See Instances for further information.

To switch the Content pane display on and off

• From the View menu, choose Content.

  When the Content pane is displayed in the main application window, a check mark is shown next to this menu command.

Properties Pane

The Properties pane at the bottom right of the main application window shows properties (metadata) for the object that is currently selected in the navigation tree. There are two types of information:

• Schemas, Doctypes and Instance Nodes
  For a schema, the schema type (for example, TSD4) and the media type (for example, text/xml) are shown.

  For a doctype, the doctype name is shown and whether this is a non-XML doctype or not.

  For an instance (XML or non-XML), date and time of the last modification are shown as well as the media type (for example, text/xml or image/gif).

• Other Nodes
  Other nodes are the nodes for servers, databases, collections, groups of schemas and groups of instances. The information shown in the Properties pane depends on the type of node which is currently selected in the navigation tree. It may include the names of the doctype, schema, collection, database and server (URL and version). It may also include the state of the database (connected or not), the type of collection (user collection or system collection) and whether the collection is WebDAV-enabled. For a group of schemas, the schema version (for example, TSD4) is shown. For a group of instances, information about the instance descriptor (if defined) and the instance fetch options is shown.

Depending on the type of object, one or more views are available. When different views are available, they can be activated using the following buttons in the top right corner of the Properties pane:

Button	Keyboard	Description
	CTRL+SHIFT+T	Tree view. Whether lines are wrapped in tree view depends on the corresponding setting in the Options dialog box. See Setting the Tamino X-Plorer and X-Query Options for further information.
	CTRL+SHIFT+P	Plain view providing the properties of a schema, doctype or instance node as name/value pairs in a table. Not available for other nodes.

The following example shows the properties for an XML instance in tree view:

The following example shows the plain view for the same instance:

To switch the Properties pane display on and off

• From the View menu, choose Properties.

  When the Properties pane is displayed in the main application window, a check mark is shown next to this menu command.

Dialog Boxes

Most Tamino X-Plorer dialog boxes can be resized. This is indicated by the following symbol in the lower right corner of a dialog box:

Resizing a dialog box is helpful if a string is so long that it is not fully shown.

Keyboard users should additionally note the use of the following keys:

Key	Function
ENTER	Activate the default button.
ESCAPE	Cancel the current operation and close the dialog box.

Navigating in the Tamino X-Plorer

You can navigate in the Tamino X-Plorer using the standard mouse and/or keyboard techniques for navigating through the menus and selecting items.

Keyboard users should additionally note the use of the following keys:

Key	Function
F2	Activate the selected input field for editing (edit mode).
ALT+DOWN-ARROW and ALT+UP-ARROW	Open and close a drop-down list box in a dialog box. To open and close a drop-down list box in a table, invoke edit mode (F2) first.
TAB	Select the next control, or select the next item in a table.
CTRL+TAB	If a control uses TAB for its own purposes (for example, a table), you have to use CTRL+TAB to leave the context of current control.
