IMetricsManager interface

Interface for a metrics manager.

Signature:

export interface IMetricsManager 

Methods

Method Description
getAbsoluteMetrics() Gets the absolute left and absolute top in pixel coordinates. This is where the visible workspace starts in relation to the SVG container.
getContentMetrics(opt_getWorkspaceCoordinates) Gets content metrics in either pixel or workspace coordinates. The content area is a rectangle around all the top bounded elements on the workspace (workspace comments and blocks).
getFlyoutMetrics(opt_own) Gets the width and the height of the flyout in pixel coordinates. By default, will get metrics for either a simple flyout (owned directly by the workspace) or for the flyout owned by the toolbox. If you pass opt_own as true then only metrics for the simple flyout will be returned, and it will return 0 for the width and height if the workspace has a category toolbox instead of a simple toolbox.
getMetrics() Returns an object with all the metrics required to size scrollbars for a top level workspace. The following properties are computed: Coordinate system: pixel coordinates, -left, -up, +right, +down .viewHeight: Height of the visible portion of the workspace. .viewWidth: Width of the visible portion of the workspace. .contentHeight: Height of the content. .contentWidth: Width of the content. .svgHeight: Height of the Blockly div (the view + the toolbox, simple or otherwise), .svgWidth: Width of the Blockly div (the view + the toolbox, simple or otherwise), .viewTop: Top-edge of the visible portion of the workspace, relative to the workspace origin. .viewLeft: Left-edge of the visible portion of the workspace, relative to the workspace origin. .contentTop: Top-edge of the content, relative to the workspace origin. .contentLeft: Left-edge of the content relative to the workspace origin. .absoluteTop: Top-edge of the visible portion of the workspace, relative to the blocklyDiv. .absoluteLeft: Left-edge of the visible portion of the workspace, relative to the blocklyDiv. .toolboxWidth: Width of the toolbox, if it exists. Otherwise zero. .toolboxHeight: Height of the toolbox, if it exists. Otherwise zero. .flyoutWidth: Width of the flyout if it is always open. Otherwise zero. .flyoutHeight: Height of the flyout if it is always open. Otherwise zero. .toolboxPosition: Top, bottom, left or right. Use TOOLBOX_AT constants to compare.
getScrollMetrics(opt_getWorkspaceCoordinates, opt_viewMetrics, opt_contentMetrics) Returns the metrics for the scroll area of the workspace.
getSvgMetrics() Gets the width and height of the workspace's parent SVG element in pixel coordinates. This area includes the toolbox and the visible workspace area.
getToolboxMetrics() Gets the width, height and position of the toolbox on the workspace in pixel coordinates. Returns 0 for the width and height if the workspace has a simple toolbox instead of a category toolbox. To get the width and height of a simple toolbox, see .
getUiMetrics() Returns common metrics used by UI elements.
getViewMetrics(opt_getWorkspaceCoordinates) Gets the metrics for the visible workspace in either pixel or workspace coordinates. The visible workspace does not include the toolbox or flyout.
