Element Context Menus
The tree view in the Export Template view for XHTML represents
a real-time DOM tree. Each XHTML element of the tree in the Header
and Detail sections has a pop-up menu. The pop-up menu items perform
DOM-based actions for modifying the structural layout of the XHTML
document that will be generated. The menu options include:
|
Menu item |
DOM-based action |
|---|---|
|
Edit |
DOMNode::SetNodeName |
|
Add Child |
DOMNode::AppendChild |
|
Insert Before |
DOMNode::InsertBefore |
|
Delete |
DOMNode::RemoveChild |
DOM–based actions
Edit allows changing the label of the tree view item representing
the XHTML element name. All element items that display no attributes,
as well as literal text nodes selected in the tree view, can also
be edited with a single mouse–click or with the shortcut
key F2. Add Child allows appending an entity as a last child. The
submenu option DataWindow Control Reference invokes a dialog containing
a filtered list box of Column, Computed Field, and Text controls
for user selection. Control references can also be added to empty attribute
values or element contents using drag-and-drop from the existing Control
List View. DataWindow Expressions can also be added using the existing
dialog. DataWindow column references (in the form of expressions) can
also be added using drag-and-drop from the Column Specification
View. Tree view items, except the <form> element,
can also be deleted with the Delete key.
Presentation and function
The remaining context menu items invoke dialogs that allow
overriding presentational and functional specifications of each
element. These include:
-
Style declarations
-
Element attributes
-
JavaScript event handlers
The dialogs first display these specifications as they would
be generated at runtime by default. The painter gets these from
the XML Web Generator in DWE in real-time, read-only display on
one half of the dialog. Within input field(s) on the other half
of the dialog, the developer can override these specifications at
the atomic declaration or attribute level. This includes resetting
included declarations/attributes, setting declarations/attributes
not included, or removing declarations/attributes. These
change specifications will then persist in the XHTML export template,
and be applied to the default presentation generated by the XML
Web Generator at runtime.
