This feature is new in Q 4.8.
RuleForm
Provides Rules with methods for defining and interrogating controls. These controls will be shown to the user when the user creates or edits a Rule. Appears to Rule code as the form variable.
checkBox(arguments)
Creates a new labelled checkBox control. Note that the label is shown on the left. If you would prefer that the label is shown to the right of the checkBox, use the old-style form.newCheckBox(). If setInputControls() is present, then then control will only appear if it is listed in the array given to setInputControls(), otherwise it will appear automatically.
| arguments | A dictionary of arguments to pass to the function: "label": A label which appears adjacent to the control (a string). "name": The name of the control (a string). If not specified, one will be automatically created. "prompt": The text (an html string) for the tooltip. Default: none. "page": The name of the page in the Inspector to place the control on. The default is set by calling form.page, which in turn defaults to "Inputs". "group": The name of the group in the Inspector to place the control on. The default is set by calling form.group, which in turn defaults to "", which is an unnamed group at the top of the page. |
| Returns: | A new ScriptLabelledCheckBox object. |
