DrawingPanel

DrawingPanel(options)

Sometimes you need to access new drawn geometries to do some process within an app, but you cannot access the geometries scope.

Options:

• width: panel width
• height: panel height
• border: panel border (example: '1px solid black')
• position: panel position (example: 'top-center')
• layout: panel layout (example: ui.Panel.Layout.flow('vertical'))
• drawings: the type of drawings to include in dropdown, currently only 'polygon' is available
• map: the map instance. Defaults to Map
• map_callback: if the map has already a callback for onClick, must be provided here to recover it
• map_callback_id: if the map has already a callback for onClick, must be provided its ID here to recover it
• title: a title for the panel

Methods:

• start(): starts the drawing
• stop(): stops the drawing
• addTo(widget): adds the panel to the parsed widget
• insertTo(widget, position): inserts the panel to the parsed widget in the parsed position
• onStart(callback): registers a callback that's fired when the drawing starts. The argument for the callback is the DrawingPanel widget
• onStop(callback): registers a callback that's fired when the drawing stops. The argument for the callback is first the DrawingPanel widget and second the actual drawing (geometry).
