Class: HorizontalFlyout

Constructor

HorizontalFlyout

new HorizontalFlyout(workspaceOptions)

Class for a flyout.

Parameter
workspaceOptions	Object Dictionary of options for the workspace. Value must not be null.

Parameter

workspaceOptions

Object

Dictionary of options for the workspace.

Value must not be null.

Extends: Blockly.Flyout

Properties

autoClose

unknown

Does the flyout automatically close when a block is created?

Inherited from: Blockly.Flyout#autoClose

buttons_

protected

unknown

List of visible buttons.

Inherited from: Blockly.Flyout#buttons_

CORNER_RADIUS

constant

unknown

Corner radius of the flyout background.

Inherited from: Blockly.Flyout#CORNER_RADIUS

dragAngleRange_

protected

unknown

Range of a drag angle from a flyout considered "dragging toward workspace". Drags that are within the bounds of this many degrees from the orthogonal line to the flyout edge are considered to be "drags toward the workspace". Example: Flyout Edge Workspace [block] / <-within this angle, drags "toward workspace" | [block] ---- orthogonal to flyout boundary ---- | [block] \ | The angle is given in degrees from the orthogonal.

This is used to know when to create a new block and when to scroll the flyout. Setting it to 360 means that all drags create a new block.
