Methods

addConstraint

addConstraints

addSubview

becomeFirstResponder

  • becomeFirstResponder(): boolean

  • Notifies the object that it's about to become the first responder.

    Returns boolean

    Whether to accept the first responder status

bringSubviewToFront

convertToWindowSpace

cursorPos

  • cursorPos(): undefined | [CCPoint, number]

  • This is used to place a blinking cursor on screen while not drawing. It's only called on the first responder of a window.

    Returns undefined | [CCPoint, number]

    The position and color of the cursor in window coordinates, or undefined to not place a cursor

didAddSubview

didMoveToSuperview

didRemoveSubview

display

  • display(rect: CCRect): void

  • Displays a view in the specified rectangle. This should not be called by other code.

    Parameters

    • rect: CCRect

      The rectangle to draw inside

    Returns void

draw

  • draw(rect: CCRect): void

  • Draws the view inside the specified rectangle. Override this function to provide custom view types.

    Parameters

    • rect: CCRect

      The rectangle to draw inside

    Returns void

hitTest

  • hitTest(point: CCPoint): undefined | CCView

  • Returns the furthest descendant that contains the specified point.

    Parameters

    • point: CCPoint

      The point to look for

    Returns undefined | CCView

    The deepest view that hit the point, or undefined if none was found

horizontalScrollWheel

interpretKeyEvents

  • interpretKeyEvents(events: CCEvent[]): void

  • Sends a list of key input events to the input manager, which will send back text input events through insertText(text: string).

    Parameters

    • events: CCEvent[]

      The input events to send

    Returns void

keyDown

keyUp

layoutSubtree

  • layoutSubtree(): void

  • Lays out the view hierarchy following constraints. This should only be called on a superview, which is done automatically.

    Returns void

mouseDown

mouseDragged

mouseEntered

mouseExited

mouseMoved

mouseUp

noResponder

  • noResponder(method: string): void

  • Handles when a method action fails to find a responder.

    Parameters

    • method: string

      The method that was attempted

    Returns void

otherMouseDown

otherMouseDragged

otherMouseUp

removeConstraint

removeFromSuperview

resignFirstResponder

    Whether to resign first responder status

rightMouseDown

rightMouseDragged

rightMouseUp

scrollWheel

sendSubviewToBack

setNeedsDisplay

setNeedsLayout

  • setNeedsLayout(sender: CCView, previous: CCView): void

  • Tells the receiver that the frame or constraints of the sender changed. This triggers the receiver to update its constraints if any are related to the sender, and cascades the message up and down throughout the hierarchy. It will also trigger a cascade on itself if it needs to update constraints.

    Parameters

    • sender: CCView

      The view whose frame and/or constraints changed

    • previous: CCView

      The view that called this method, to prevent backtracking

    Returns void

textInput

tryToCall

  • tryToCall(method: string, ...args: any[]): boolean

  • Attempts to call the specified method on the object, passing the call on to the next responder if this object doesn't implement it.

    Parameters

    • method: string

      The name of the method to call

    • ...args: any[]

      Any parameters to pass to the method

    Returns boolean

    Whether a responder was able to respond to the method

validateProposedFirstResponder

StaticaddConstraintsByCode

  • addConstraintsByCode(code: string, views: { [name: string]: CCView }): void

  • Adds a number of constraints to views using code. This can simplify settings constraints by using familiar code syntax instead of lengthy constraint constructions and activations.

    The syntax is fairly simple:

    <ViewName>.<Attribute> = [<Multiplier> *] <ViewName>.<Attribute> [+|- <Constant>]
<ViewName>.<Attribute> = <Constant>

    The code is processed using Lua as the parser, so it's not strictly required to be in exactly this format; but mind that operators other than add/sub/mul/div/unm aren't supported (and division is only valid if the divisor is a number), and no libraries are available in the environment.

    Parameters

    • code: string

      The constraint code to apply

    • views: { [name: string]: CCView }

      A key-value map of names of views in the code, to the views they represent

    Returns void
