Text Editor

The Text Editor is part of the Ventuz User Interface and is used to edit text, expressions, XML or other textual information. In all of these cases, having to enter or manipulate large amounts of text directly in the Property Editor would be difficult due to its limited screen size, thus for such items one can use this dedicated editor window. The Text Editor is at all times either associated with none or exactly one string property. The value box of this property in the Property Editor will be shaded in a light red color. If a node contains more than one string properties, the selection can be changed by clicking into the respective value field in the Property Editor.

Edit Formatted Text

The most common use of the Text Editor is to edit formatted text such as that used by the Block Text node. In this case, the editor looks something like below: The main area is of course reserved to the text input. In the top toolbar are various options that should be familiar to any user that has ever worked with a word processor such as the alignment of the text. The majority of these buttons is directly related to properties of the Text Layout node that is selected and any change in the Text Editor is just a quick way of changing the respective property in the Property Editor.

The bottom toolbar also contains shortcuts to properties usually found in the Property Editor. Depending on the Text Layout node, it can be used to influence the size of the area the layouted text will use, what spacing should be used between lines and so on.

Bottom Toolbar

Edit String Values

When editing string values (for example for the inputs of String Operation nodes, all invalid properties and functionality, compared to Text Layout nodes, are removed. As a result, the text editor looks rather sparse and functions merely as a way to enter plain text.

Edit XML

When editing XML data (see [NodeDataXML XML Text node]), the editor features syntax highlighting capabilities. In addition, it checks the content for being well-formed (e.g. a closing tag exists for each open tag, a tag is only closed when all its child tags are closed, ...). It however does not perform any validation against a DTD file which may or may not be specified in the content.

Edit Expressions

Expressions are small pieces of C# code and the Text Editor features the appropriate syntax highlighting for them. Otherwise it behaves much like a plain text editor. For more information on expressions, see Expression Nodes.
