Get the document that this node is currently rendered in (the document of the main window or of a popout window). Returns undefined before the layout has been mounted.
Returns the tabs of this tabset in strip order. Tabs inside a closed (collapsed) group are
not included. The selected index is an index into this list.
Get the browser window that this node is currently rendered in. This is the main window for nodes in the main layout and the popout window for nodes rendered inside a popout. Returns undefined before the layout has been mounted.
Returns the config attribute that can be used to store node specific data that WILL be saved to the json. The config attribute should be changed via the action Actions.updateNodeAttributes rather than directly, for example: this.state.model.doAction( FlexLayout.Actions.updateNodeAttributes(node.getId(), {config:myConfigObject}));
