Try not to use this function, particularly if there are multiple Blockly instances on a page. |\n| [getParentContainer()](./blockly.common_namespace.getparentcontainer_1_function.md) | Get the container element in which to render the WidgetDiv, DropDownDiv and Tooltip. |\n| [getSelected()](./blockly.common_namespace.getselected_1_function.md) | Returns the current selection. |\n| [getWorkspaceById(id)](./blockly.common_namespace.getworkspacebyid_1_function.md) | Find the workspace with the specified ID. |\n| [registerWorkspace(workspace)](./blockly.common_namespace.registerworkspace_1_function.md) | Register a workspace in the workspace db. |\n| [setMainWorkspace(workspace)](./blockly.common_namespace.setmainworkspace_1_function.md) | Sets last used main workspace. |\n| [setParentContainer(newParent)](./blockly.common_namespace.setparentcontainer_1_function.md) | Set the parent container.

See workspace.resizeContents to resize the workspace when the contents change (e.g. when a block is added or removed). Record the height/width of the SVG image. |\n| [unregisterWorkpace(workspace)](./blockly.common_namespace.unregisterworkpace_1_function.md) | Unregister a workspace from the workspace db. |\n\nVariables\n---------\n\n| Variable | Description |\n|-----------------------------------------------------------------------------------|--------------------------------------------------------------------|\n| [draggingConnections](./blockly.common_namespace.draggingconnections_variable.md) | All of the connections on blocks that are currently being dragged. |\n| [TEST_ONLY](./blockly.common_namespace.test_only_variable.md) | |"]]
