Actions: oxy_action() Function

This function allows you to define actions directly in the CSS, rather than referencing them from the associated framework.

The oxy_action() function is frequently used from the oxy_button() function that provides a graphical button for invoking a custom action. The action is normally defined in the associated Document Type (framework configuration) but the oxy_action() function allows you to define it directly in the CSS instead of the framework configuration.

The arguments received by the oxy_action() function are a list of properties that define an action. The following properties are supported:

  • name - The name of the action. It will be displayed as the label for the button or menu item.
  • description (optional) - A short description with details about the result of the action.
  • icon (optional) - A path relative to the CSS pointing to an image (the icon for the action). The path can point to resources that are packed in Oxygen XML Author Eclipse plugin (oxygen.jar) by starting its value with / (for example, /images/Remove16.png). It can also be expressed using an editor variable.
  • operation - The name of the Java class implementing the ro.sync.ecss.extensions.api.AuthorOperation interface. There is also a variety of predefined operations that can be used.
    Note:
    If the name of the operation specified in the CSS is not qualified (has no Java package name), then it is considered to be one of the built-in Oxygen XML Author Eclipse plugin operations. If the class is not found in this package, then it will be loaded using the specified name.
  • arg-<string> - All arguments with the arg- prefix are passed to the operation (the string that follows the arg- prefix is passed). The argument value supports editor variables.
  • ID - (optional) - The ID of the action from the framework. If this is specified, all others parameters are disregarded.
Example: oxy_action function inside an oxy_button form control:
oxy_button(
   action, oxy_action(
            name, 'Insert', 
            description, 'Insert an element after the current one', 
            icon, url('insert.png'), 
            operation, 
             'InsertFragmentOperation', 
            arg-fragment, '<element>${caret}</element>',
            arg-insertLocation, '.',
            arg-insertPosition, 'After'), 
            showIcon, true)

Example: oxy_action Function

You can also create a button form control directly from an oxy_action function:
oxy_action(
            name, 'Insert', 
            description, 'Insert an element after the current one', 
            operation, 'InsertFragmentOperation', 
            arg-fragment, '<element>${caret}</element>',
            arg-insertLocation, '.',
            arg-insertPosition, 'After')
