14.2.2.18 lock (Shape Protections)
This element specifies locks against actions that can be effected in the UI of an authoring application or programmatically through an object model.
[Example: The following snippet locks the shape's aspect ratio and text from user edits.
<v:shape … > <o:lock v:ext="edit" aspectratio="t" text="t"/> </v:shape>
end example]

Attributes |
Description |
|---|---|
adjusthandles (Handles Lock) |
Specifies whether the handles of a shape are locked from being edited. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
aspectratio (Aspect Ratio Lock) |
Specifies whether the aspect ratio of a shape is locked from being edited. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
cropping (Cropping Lock) |
Specifies whether cropping of a shape is locked from being edited. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
ext (VML Extension Handling Behavior) Namespace: urn:schemas-microsoft-com:vml |
Specifies an optional value that indicates how applications that implement VML should interpret extensions not defined as part of the original specification of core VML. [Rationale: This part of the original VML specification is included to assist applications that leverage existing VML support in implementing the Office Open XML Format. end rationale] The possible values for this attribute are defined by the ST_Ext simple type (§14.1.3.2). |
grouping (Grouping Lock) |
Specifies whether a shape is locked from being grouped. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
position (Position Lock) |
Specifies whether the position of a shape is locked from being edited. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
rotation (Rotation Lock) |
Specifies whether the rotation of a shape is locked from being edited. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
selection (Selection Lock) |
Specifies whether the shape is locked from being selectable in an editor. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
shapetype (AutoShape Type Lock) |
Specifies whether the AutoShape type is locked from being edited. Default is false. If true, the type of an AutoShape cannot be changed in a graphical editor. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
text (Text Lock) |
Specifies whether the text attached to a shape is locked from being edited. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
ungrouping (Ungrouping Lock) |
Specifies whether a grouped shape is locked from being ungrouped. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
verticies (Vertices Lock) |
Specifies whether the vertices of a path are locked from being edited. Default is false. The possible values for this attribute are defined by the ST_TrueFalse simple type (§15.1.2.5). |
