Line/Area Ruler¶

The ruler is used to draw a line or area and display length/area in a dialog. Selecting a type determines whether the element measures lines or areas. Each ruler element can only measure either lines or areas.

Title: Title of the element. The title will be listed in “Layouts” and allows to distinguish between different buttons. It will be indicated if “Show label” is activated.
Tooltip: Text to use as tooltip.
Target: ID of Map element to query.
Type: Choose type of element: line or area.
Immediate: Select whether the calculated lengths are displayed immediately or only after the click on the map.

YAML-Definition:¶

tooltip: "ruler"   # text to use as tooltip
target: ~          # ID of Map element to query
type: 'line'       # choose type line or area
immediate: 'false' # True: Display the calculated lengths immediately. False: The calculated lengths are displayed only after clicking. Default: False.

You need a button to show this element. See Button for inherited configuration options. To use both functions (measuring areas and lines) in an application, you need two buttons that are in a group.
