View

super: UIScrollView (on iOS)

The View class defines a rectangular area on the screen and the interfaces for managing the content in that area. At runtime, a view object handles the rendering of any content in its area and also handles any interactions with that content. The View class itself provides basic behavior for filling its rectangular area with a background color.

Events

  • Load() This event is called when the object becames available in the current runtime system.

  • WillShow() The view is about to be added to the App's views hierarchy.

  • WillHide() The view is about to be removed from the App's views hierarchy.

  • Draw(rect: Rect) Draws the receiver’s image within the passed-in rectangle.

  • TouchesBegan(touches: Object): Bool This event is called when one or more new touches occurred in this view and the userInteractionEnabled property is enabled. Return "true" if you want to consume the event and not forward it to the next responder, return "no" to forward any events that you do not handle yourself.

  • TouchesMoved(touches: Object, touchInside: Bool): Bool This event is called when the location or force of a touch changes and the userInteractionEnabled property is enabled. Return "true" if you want to consume the event and not forward it to the next responder, return "no" to forward any events that you do not handle yourself.

  • TouchesEnded(touches: Object, touchInside: Bool): Bool This event is called when one or more fingers are raised and the userInteractionEnabled property is enabled. Return "true" if you want to consume the event and not forward it to the next responder, return "no" to forward any events that you do not handle yourself.

  • TouchesCancelled(touches: Object): Bool This event is called when the sysyem receives a system interruption (such as a system alert) requiring cancellation of the touch sequence and the userInteractionEnabled property is enabled. Return "true" if you want to consume the event and not forward it to the next responder, return "no" to forward any events that you do not handle yourself.

  • ViewForZooming(): UIView Asks for the view to scale when zooming is about to occur in the scroll view. Return nil if you don’t want zooming to occur. Zooming is enabled if you returns a valid view in this event and if the maximumZoomScale is greater than the minimumZoomScale. Pinch to zoom is not currently supported in Creo Simulator but it works in iOS devices and in the Apple iOS simulators.

  • DidZoom() This event is called when the scroll view’s zoom factor changed.

  • DidScroll() This event is called when the user scrolls the content view.

  • DidEndDragging(decelerate: Bool) This event is called when dragging ended in the scroll view. The scroll view sends this event when the user’s finger touches up after dragging content. The decelerating property of the scroll view controls deceleration. The decelerate value is true if the scrolling movement will continue, but decelerate, after a touch-up gesture during a dragging operation. If the value is NO, scrolling stops immediately upon touch-up.

  • DidEndDecelerating() This event is called when the scroll view ends decelerating the scrolling movement.

  • DidShow() The view has been added to the App's views hierarchy.

  • DidHide() The view has been removed from the App's views hierarchy.

  • Unload() This event is called when the object has been removed from the current runtime system (but not yet deallocated).

Properties

  • var passthroughTouches: Bool A Boolean value that determines whether user events are ignored by the view. This property doesn't affect the user interaction with subviews.

  • var autoContentSize: Int A value that specifies how the view should calculate its size to eventually scroll. With Manual you have to specifiy the size via contentSize and the view may scroll if the size in any direction is bigger than the frame; with Fixed the content size always matches the frame, therefore the content can not scroll by user interaction; with Flex (and if flex is enabled) the size depends on how much space the childrens require along the flex main direction, the view may become scrollable if the display does not fit the space required.

  • var rowIndex: Int Use this property to set row index in case of view used in a controls that require an array of views.

  • var customView: CustomView Custom view template set in the View inspector.

  • var dataSet: Object The DataSet object provides information that View needs to construct its content. The dataSet must return a List of objects and each object represents a different row. If the DataSet value is not flat, for example a Map from a JSON result of an HTTPRequest, the keyPath property defines the list of keys used to browse the data tree to get a List node.

  • var keyPath: String The base keyPath to get a particular node of the DataSet value. The DataSet must provide a List of objects and each object represents a different item. The view shows an item at a time, depending on the rowIndex property value. If the DataSet value is not flat, for example a Map from a JSON result of an HTTPRequest, the keyPath defines the list of keys used to browse the data tree to get a List node. The values for each exposed property of the cell are retrieved by adding the current index and the cell property key to the base keyPath.

  • var minimumZoomScale: Float A floating-point value that specifies the minimum scale factor that can be applied to the scroll view's content. The default value is 1.0.

  • var maximumZoomScale: Float A floating-point value that specifies the maximum scale factor that can be applied to the scroll view's content. The default value is 1.0. Zooming is enabled if you returns a valid view in the ViewForZooming event and if the maximumZoomScale is greater than the minimumZoomScale.

  • var zoomScale: Float A floating-point value that specifies the current scale factor applied to the scroll view's content. The default value is 1.0.

  • var objectName: String The name of the object.

Methods

  • func reload(reloadDataSet: Bool) Reloads the content of the view.

  • func image(): Image Returns the rasterized Image of the current view.

  • func animate(duration: Float, delay: Float, options: AnimationOption, animations: Closure, completion: Closure) Animate changes to one or more views using the specified duration, delay, options and completion handler.

  • func setFocus() Force focus to be set to the selected control. For TextField and TextView that means force Keyboard to appear.

  • func clearFocus() Clear focus from selected control
