XPresso Manager

The XPresso manager provides a simplified overview of an expression as a hierarchical list of nodes and XGroups. In addition to providing this clear overview, the XPresso manager is useful for quickly selecting elements, changing their order and rearranging the hierarchy. Nodes that belong to an XGroup are listed below their parent XGroup and are indented.

XPresso 管理器将表达式简化为节点和 XGroups 的分层列表。除了提供这种清晰的概述之外，XPresso 管理器还可以用于快速选择元素、更改元素的顺序和重新排列层次结构。属于 XGroup 的节点列在其父节点 XGroup 的下面，并缩进。

To open the XPresso manager:

打开 XPresso 管理器:

The XPresso manager is integrated into the XPresso Editor by default. However, should you undock and close the manager, you can reopen it by choosing Custom / XPresso Manager in the XPresso Editor.

XPresso 管理器默认集成到 XPresso 编辑器中。但是，如果您取消停靠并关闭管理器，您可以通过在 XPresso 编辑器中选择 Custom/XPresso Manager 来重新打开它。

To move a node into an XGroup:

将一个节点移动到 XGroup 中:

• Drag the node name and drop it onto the XGroup name. 拖动节点名并将其拖放到 XGroup 名称上
To move a node into view in the XPresso Editor: 在 XPresso 编辑器中移动一个节点到视图中:
• Drag the name of the node from the XPresso manager and drop it onto the desired position in the XPresso Editor. 从 XPresso 管理器中拖动节点的名称，并将其拖放到 XPresso 编辑器中所需的位置
To open and close hierarchies: 打开和关闭层次结构:
• Click the icon to the left of the node or XGroup name. 单击节点或 XGroup 名称左侧的图标
To create a new empty XGroup: 创建一个新的空的 XGroup:
• Right-click (Windows) or Command-click (macOS) on the root XGroup’s name in the XPresso Manager window and choose New XGroup / Empty XGroup from the context menu. 在 XPresso Manager 窗口中右键单击根 XGroup 的名称(Windows)或 Command-click (macOS) ，然后从上下文菜单中选择 New XGroup/Empty XGroup
To control the order of evaluation: 控制评价的顺序:
• Drag a node or XGroup name and drop it in a new position. 拖动一个节点或 XGroup 名称并将其放置到新位置
• The top-most elements in the XPresso manager are evaluated first. This order is especially important when the result of a node is passed to another XGroup, otherwise the values passed may be incorrect and the expression may fail to work as intended. 先评估 XPresso 管理器中最顶层的元素。当一个节点的结果传递给另一个 XGroup 时，这个顺序尤其重要，否则传递的值可能不正确，表达式可能无法按预期的方式工作
