Schema Tree

The Tamino Schema Editor provides different views. See Switching to Another View for further information.

When one of the tree views is active, the left side of the application window shows a tree of the current Tamino schema, for example:

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

When you select an item, the logical and/or physical properties of this item are displayed on the right side of the application window, but the item is not expanded.

The following icons may appear in the tree (see Schema Tree Items Explained for further information):

	All
	Annotation
	Any
	AnyAttribute
	Appinfo
	Attribute
	AttributeGroup
	AttributeGroup reference
	Attribute info
	Attribute reference
	Choice
	ComplexType
	Documentation
	Doctype
	Element complex
	Element info
	Element reference
	Element simple
	Element unknown
	Element with attributes
	Group
	Group reference
	Import
	Include
	Key
	Keyref
	Notation
	Redefine
	Schema
	Sequence
	SimpleType
	SimpleType with attributes
	Unique

Characters may appear to the right of an icon in the schema tree. See Specifying the Occurrence Constraints and Declaring an Element as Optional, Required or Prohibited for detailed information.

To expand all nodes in the tree

• From the View menu, choose Expand All.

Schema Status

When you modify a schema, the tab containing the name of the schema is shown with an asterisk "*". This is a reminder that your changes have not yet been saved. When you save the schema, for example using File > Save, the asterisk is removed.

Tooltips in the Schema Tree

In the schema tree, tooltips indicating the type of schema construct can be shown. By default, this feature is disabled. To enable this feature, you have to add the following line to the file parameter.properties which is located in the root directory of your Tamino Schema Editor installation:

com.softwareag.xtools.schematools.schemaeditor.components.SchemaTree.SchemaTree.showTreeNodeToolTip=true

Structure Info Text

Structure info text is the gray information in the schema tree (for example, "Sequence", "Choice" or "Annotation"). For better readability, you can disable the display of this information.

To display/hide the structure info text in the schema tree

• From the View menu, choose Show Structure Info Text.

  When the structure info text is displayed in the schema tree, a check mark is shown next to this menu command.

Context Menus

Context menus are available for the elements in the schema tree. For example, the following context menu is available when you select a simple element:

To invoke a context menu for an element or attribute

1. Select the element or attribute 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.

A context menu with features that apply globally to a schema (such as several of the entries in the File menu) is also available from the schema tab.

To invoke the context menu for a schema

1. Move the cursor to the tab where the name of the schema is displayed.

2. Click the right mouse button.

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

Logical Properties

When one of the tree views is active, the logical properties of the element that is currently selected in the schema tree are shown at the top right of the application window. Example:

The Property column displays the property name. The Value column displays the current property value, which you can modify.

You can expand or collapse the tree structure by clicking the plus or minus sign in front of an item. When using the keyboard, select the node, press F2 to activate edit mode and then and press CTRL+RIGHT-ARROW or CTRL+LEFT-ARROW.

See Properties Explained for detailed information.

Physical Properties

When one of the tree views is active, the physical properties of the element that is currently selected in the schema tree are shown at the bottom right of the application window. The physical properties are shown according to the selected storage type. Example:

The Property column displays the property name. The Value column displays the current property value, which you can modify. See Properties Explained for detailed information.

For some element types, an Advanced button is provided. When you choose this button, additional information is shown. You can then define the physical properties of a node that can be accessed via multiple paths. See Advanced Physical Properties.

Switching to Another View

When you open a schema, it is always shown in a view which is able to display the whole schema.

A schema which does not match XSD is opened in code view. You can modify the code manually in code view. However, it is only possible to switch back to one of the tree views if this tree view is able to display the whole schema.

To switch to tree view

This description assumes that you want to switch to tree view or that code view is currently active.

• From the View menu, choose XSD.

  If the current schema contains information which is not supported in another view, switching is not possible. The output panel will then inform you why the switch is not possible.

  In the View menu, a check mark is always shown next to the menu command which corresponds to the current view. The toolbar button for the current view is always shown in down status.

To switch to code view

This description assumes that one of the tree views is currently active.

• From the View menu, choose Code.

  Or:
  Select the toolbar button for code view.

  

  In the View menu, a check mark is always shown next to the menu command which corresponds to the current view. The toolbar button for the current view is always shown in down status.

Code View

When you switch to code view, a code editor is shown instead of the schema tree, logical properties and physical properties which are shown in tree view.

Using the commands from the Edit menu, you can, for example, cut and paste or find and replace information.

Output Panel

The output panel at the bottom of the application window displays status messages about the last action that has been performed. For example, it tells you that a replace operation has been completed, or it provides information about errors that appear when you try to switch from code view to one of the tree views.

If a hyperlink is provided for an error, you can choose it. You are then positioned at the entry that caused the error. If you are working in code view, the corresponding line and column numbers are provided at the beginning of the hyperlink text.

To switch the output panel display on and off

• From the View menu, choose Output.

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

Status Bar

The status bar is the horizontal information line at the bottom of the main application window.

In code view, the following information is shown: the numbers of the current line and column, and the total amount of lines in the current schema.

To switch the status bar display on and off

• From the View menu, choose Status Bar.

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

Dialog Boxes

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

To resize a dialog box

1. Move the cursor to the bottom-right corner of the dialog box. The cursor shape changes to a two-headed arrow.

2. Using the left mouse button, drag the box to the required size.

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

Navigating in the Schema Editor

You can navigate in the Tamino Schema Editor using the standard mouse and/or keyboard techniques for navigating through the menus and selecting items. You can edit names of elements and attributes both in tree view, as well as in the corresponding property pane.

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. In edit mode: open and close a drop-down list box in the Value column of the logical or physical properties.
CTRL+RIGHT-ARROW and CTRL+LEFT-ARROW	In edit mode: open and close a group tree in the Property column of the logical properties.
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.
CTRL+ENTER	If a control uses ENTER for its own purposes (for example, the property editor in which you enter documentation text), you have to use CTRL+ENTER to choose the default button.
