An event reporting a button was pressed. An event reporting a button was pressed. An event reporting a button was released. An event reporting a button was released. An event announcing that the buttons are focused on this element. An event announcing that the buttons is no longer focused on this element OnChildrenChanged is called when the UIElementCollection of the UIElement is edited. Recursively propagates IsLayoutSuspended flag down to the whole v's sub tree. Recursively resets IsLayoutSuspended flag on all visuals of the whole v's sub tree. For UIElements also re-inserts the UIElement into Measure and / or Arrange update queues if necessary. Updates DesiredSize of the UIElement. Must be called by parents from their MeasureOverride, to form recursive update. This is first pass of layout update. Measure is called by parents on their children. Internally, Measure calls MeasureOverride override on the same object, giving it opportunity to compute its DesiredSize. This method will return immediately if child is not Dirty, previously measured and availableSize is the same as cached. This method also resets the IsMeasureinvalid bit on the child. In case when "unbounded measure to content" is needed, parent can use availableSize as double.PositiveInfinity. Any returned size is OK in this case. Available width that parent can give to the child. May be MaxValue (when parent wants to measure to content). This is soft constraint. Child can return bigger size to indicate that it wants bigger space and hope that parent can throw in scrolling... Available height that parent can give to the child. May be MaxValue (when parent wants to measure to content). This is soft constraint. Child can return bigger size to indicate that it wants bigger space and hope that parent can throw in scrolling... Parents or system call this method to arrange the internals of children on a second pass of layout update. This method internally calls ArrangeOverride override, giving the derived class opportunity to arrange its children and/or content using final computed size. In their ArrangeOverride overrides, derived class is supposed to create its visual structure and prepare itself for rendering. Arrange is called by parents from their implementation of ArrangeOverride or by system when needed. This method sets Bounds=finalSize before calling ArrangeOverride. This is the final X location that parent or system wants this UIElement to assume. This is the final Y location that parent or system wants this UIElement to assume. This is the Width that parent or system wants this UIElement to assume. This is the height that parent or system wants this UIElement to assume. Measurement override. Implement your size-to-content logic here. MeasureOverride is designed to be the main customizability point for size control of layout. UIElement authors should override this method, call Measure on each child UIElement, and compute their desired size based upon the measurement of the children. The return value should be the desired size. Note: It is required that a parent UIElement calls Measure on each child or they won't be sized/arranged. Typical override follows a pattern roughly like this (pseudo-code): The key aspects of this snippet are: You must call Measure on each child UIElement It is common to cache measurement information between the MeasureOverride and ArrangeOverride method calls Calling base.MeasureOverride is not required. Calls to Measure on children are passing either the same availableSize as the parent, or a subset of the area depending on the type of layout the parent will perform (for example, it would be valid to remove the area for some border or padding). Available size that parent can give to the child. May be MaxValue(when parent wants to measure to content). This is soft constraint. Child can return bigger size to indicate that it wants bigger space and hope that parent can throw in scrolling... ArrangeOverride allows for the customization of the final sizing and positioning of children. UIElement authors should override this method, call Arrange on each visible child UIElement, to size and position each child UIElement by passing a rectangle reserved for the child within parent space. Note: It is required that a parent UIElement calls Arrange on each child or they won't be rendered. Typical override follows a pattern roughly like this (pseudo-code): Final width Final height Call this method to ensure that the whoel subtree of elements that includes this UIElement is properly updated. This ensures that UIElements with IsMeasureInvalid or IsArrangeInvalid will get call to their MeasureOverride and ArrangeOverride, and all computed sizes will be validated. This method does nothing if layout is clean but it does work if layout is not clean so avoid calling it after each change in the UIElement tree. It makes sense to either never call it (system will do this in a deferred manner) or only call it if you absolutely need updated sizes and positions after you do all changes. We are deviating little from their desktop counter parts, mostly for simplicity and perf. Invalidates the measurement state for the UIElement. This has the effect of also invalidating the arrange state for the UIElement. The UIElement will be queued for an update layout that will occur asynchronously. Invalidates the arrange state for the UIElement. The UIElement will be queued for an update layout that will occur asynchronously. MeasureOverride will not be called unless InvalidateMeasure is also called - or that something else caused the measure state to be invalidated. The CompositionTarget marks the root element. The root element is responsible for posting renders. This method is also used to ensure that the Visual is not used in multiple CompositionTargets. Notification that is called by Measure of a child when it ends up with different desired size for the child. Default implementation simply calls invalidateMeasure(), assuming that layout of a parent should be updated after child changed its size. Finer point: this method can only be called in the scenario when the system calls Measure on a child, not when parent calls it since if parent calls it, it means parent has dirty layout and is recalculating already. Raise the events specified by This method is a shorthand for This method walks up the visual tree, calling on every NOTE: The RoutedEvent in RoutedEventArgs and EventRoute must be matched Once the route is built, it calls InvokeHandlers() for the event to be raised Add the event handlers for this element to the route. Adds a routed event handler for the particular The handler added thus is also known as an instance handler NOTE: It is not an error to add a handler twice (handler will simply be called twice) Input parameters and handler cannot be null handledEventsToo input parameter when false means that listener does not care about already handled events. Hence the handler will not be invoked on the target if the RoutedEvent has already been handledEventsToo input parameter when true means that the listener wants to hear about all events even if they have already been handled. Hence the handler will be invoked irrespective of the event being for which the handler is attached The handler that will be invoked on this object when the RoutedEvent is raised Flag indicating whether or not the listener wants to hear about events that have already been handled A property indicating if the button is focused on this element or not. Determines if the DesiredSize is valid. A developer can force arrangement to be invalidated by calling InvalidateMeasure. IsArrangeValid and IsMeasureValid are related, in that arrangement cannot be valid without measurement first being valid. Determines if the RenderSize and position of child elements is valid. A developer can force arrangement to be invalidated by calling InvalidateArrange. IsArrangeValid and IsMeasureValid are related, in that arrangement cannot be valid without measurement first being valid. Visibility accessor A property indicating if this element is Visible or not. Fetches the value of the IsEnabled property Ensure the store has been created. Summary description for Image. Event handler if the scroll changes. Horizontal offset of the scroll. Vertical offset of the scroll. Extent height of the scroll area. Extent width of the scroll area. The scrolling style. A UIElementCollection is a ordered collection of UIElements. A UIElementCollection has implied context affinity. It is a violation to access the collection from a different context than that of the owning Element This collection is an amalgam of UIElementCollection and UIElementCollection from Avalon Copies the UIElement collection to the specified array starting at the specified index. Strongly typed version of CopyTo Copies the collection into the Array. Ensures that the capacity of this list is at least the given minimum value. If the currect capacity of the list is less than min, the capacity is increased to min. Sets the specified element at the specified index into the child collection. It also corrects the parent. Note that the function requires that _item[index] == null and it also requires that the passed in child is not connected to another UIElement. If the new child has already a parent or if the slot a the specified index is not null. Disconnects a child. Appends a UIElement to the end of the UIElementCollection. The UIElement to be added to the end of the UIElementCollection. The UIElementCollection index at which the UIElement has been added. Adding a null is allowed. If the new child has already a parent. Returns the zero-based index of the UIElement. If the UIElement is not in the UIElementCollection -1 is returned. If null is passed to the method, the index of the first entry with null is returned. If there is no null entry -1 is returned. The UIElement to locate in the UIElementCollection. Removes the specified element from the UIElementCollection. The UIElement to remove from the UIElementCollection. The UIElements that follow the removed UIElements move up to occupy the vacated spot. The indexes of the UIElements that are moved are also updated. If element is null then the first null entry is removed. Note that removing a null entry is linear in the size of the collection. Determines whether a element is in the UIElementCollection. Removes all elements from the UIElementCollection. Count is set to zero. Capacity remains unchanged. To reset the capacity of the UIElementCollection, call TrimToSize or set the Capacity property directly. Inserts an element into the UIElementCollection at the specified index. The zero-based index at which value should be inserted. The UIElement to insert. index is less than zero. -or- index is greater than Count. If Count already equals Capacity, the capacity of the UIElementCollection is increased before the new UIElement is inserted. If index is equal to Count, value is added to the end of UIElementCollection. The UIElements that follow the insertion point move down to accommodate the new UIElement. The indexes of the UIElements that are moved are also updated. Removes the UIElement at the specified index. The zero-based index of the element to remove. index is less than zero - or - index is equal or greater than count. The UIElements that follow the removed UIElements move up to occupy the vacated spot. The indexes of the UIElements that are moved are also updated. Removes a range of UIElements from the UIElementCollection. The zero-based index of the range of elements to remove The number of elements to remove. index is less than zero. -or- count is less than zero. index and count do not denote a valid range of elements in the UIElementCollection. The UIElements that follow the removed UIElements move up to occupy the vacated spot. The indexes of the UIElements that are moved are also updated. Returns an enumerator that can iterate through the UIElementCollection. Enumerator that enumerates the UIElementCollection in order. Gets or sets the number of elements that the UIElementCollection can contain. The number of elements that the UIElementCollection can contain. Capacity is the number of elements that the UIElementCollection is capable of storing. Count is the number of UIElements that are actually in the UIElementCollection. Capacity is always greater than or equal to Count. If Count exceeds Capacity while adding elements, the capacity of the UIElementCollection is increased. By default the capacity is 0. Capacity is set to a value that is less than Count. Indexer for the UIElementCollection. Gets or sets the UIElement stored at the zero-based index of the UIElementCollection. This property provides the ability to access a specific UIElement in the UIElementCollection by using the following systax: myUIElementCollection[index]. index is less than zero -or- index is equal to or greater than Count. If the new child has already a parent or if the slot a the specified index is not null. This is a simple UIElementCollection enumerator that is based on the ArrayListEnumeratorSimple that is used for ArrayLists. The following comment is from the CLR people: For a straightforward enumeration of the entire ArrayList, this is faster, because it's smaller. Benchmarks showed this. Creates a new object that is a copy of the current instance. Advances the enumerator to the next element of the collection. Sets the enumerator to its initial position, which is before the first element in the collection. Gets the current UIElement. Gets the current UIElement. Drawing Context. The MediaContext class controls the rendering The MediaContext lives in the Dispatcher and is the MediaSystem's class that keeps per Dispatcher state. Gets the MediaContext from the context passed in as argument. If there is already a render operation in the Dispatcher queue, this method will do nothing. If not, it will add a render operation. This method should only be called when a render is necessary "right now." Events such as a change to the visual tree would result in this method being called. This is the standard RenderMessageHandler callback, posted via PostRender() and Resize(). This wraps RenderMessageHandlerCore and emits an ETW events to trace its execution. Message delegate. Indicates that we are in the middle of processing a render message. Basic algorithm uses scan lines to fill the polygon. No multiplication or division is needed, neither is floating point calculation. We will use Bresenham alg for line calc. Presentation source is our connection to the rest of the managed system. Constructs an instance of the PresentationSource object. The Root UIElement for this source. SizeToContent Does not size to content Sizes Width to content's Width Sizes Height to content's Height Sizes both Width and Height to content's size Visibility - Enum which describes 3 possible visibility options. Normally visible. Occupies space in the layout, but is not visible (completely transparent). Not visible and does not occupy any space in layout, as if it doesn't exist. Constructs a window object Automatic determination of current Dispatcher. Use alternative constructor that accepts a Dispatcher for best performance. REFACTOR -- consider specifying app default window sizes to cover Aux case for default window size. Initializes the Width/Height, Top/Left properties to use windows default. Updates Application object properties if inside app. Measurement override. Implements content sizing logic. Deducts the frame size from the constraint and then passes it on to it's child. Only supports one Visual child (just like control) ArrangeOverride allows for the customization of the positioning of children. Deducts the frame size of the window from the constraint and then arranges it's child. Supports only one child. Auto size Window to its content's size 1. SizeToContent can be applied to Width Height independently 2. After SizeToContent is set, setting Width/Height does not take affect if that dimension is sizing to content. Default value is SizeToContent.Manual Position for Top of the host window Determines if this window is always on the top. Application base class Application constructor Run is called to start an application. Typically a developer will do some setting of properties/attaching to events after instantiating an application object, and then call Run() to start the application. Once run has been called - an application's OnStartup override and Startup event is called immediately afterwards. ExitCode of the application Run is called to start an application. Typically a developer will do some setting of properties/attaching to events after instantiating an application object, and then call Run() to start the application. Once run has been called - an application's OnStartup override and Startup event is called immediately afterwards. Window that will be added to the Windows property and made the MainWindow of the Applcation. The passed Window must be created on the same thread as the Application object. Furthermore, this Window is shown once the Application is run. Shutdown is called to programmatically shutdown an application. Once shutdown() is called, the application gets called with the OnShutdown method to raise the Shutdown event. OnStartup is called to raise the Startup event. The developer will typically override this method if they want to take action at startup time ( or they may choose to attach an event). This method will be called once when the application begins, once that application's Run() method has been called. This method follows the .Net programming guideline of having a protected virtual method that raises an event, to provide a convenience for developers that subclass the event. If you override this method - you need to call Base.OnStartup(...) for the corresponding event to be raised. The event args that will be passed to the Startup event OnExit is called to raise the Exit event. The developer will typically override this method if they want to take action when the application exits ( or they may choose to attach an event). This method follows the .Net programming guideline of having a protected virtual method that raises an event, to provide a convenience for developers that subclass the event. If you override this method - you need to call Base.OnExit(...) for the corresponding event to be raised. The event args that will be passed to the Exit event DO NOT USE - internal method This method gets called on dispatch of the Shutdown DispatcherOperationCallback This DispatcherException event handler creates the default UI The Current property enables the developer to always get to the application in AppDomain in which they are running. The Windows property exposes a WindowCollection object, from which a developer can iterate over all the windows that have been opened in the current application. The MainWindow property indicates the primary window of the application. By default - MainWindow will be set to the first window opened in the application. However the MainWindow may be set programmatically to indicate "this is my main window". It is a recommended programming style to refer to MainWindow in code instead of Windows[0]. The ShutdownMode property is called to set the shutdown specific mode of the application. Setting this property controls the way in which an application will shutdown. The three values for the ShutdownMode enum are : OnLastWindowClose OnMainWindowClose OnExplicitShutdown OnLastWindowClose - this mode will shutdown the application when the last window is closed, or an explicit call is made to Application.Shutdown(). This is the default mode. OnMainWindowClose - this mode will shutdown the application when the main window has been closed, or Application.Shutdown() is called. Note that if the MainWindow property has not been set - this mode is equivalent to OnExplicitOnly. OnExplicitShutdown- this mode will shutdown the application only when an explicit call to OnShutdown() has been made. The Startup event is fired when an application is starting. This event is raised by the OnStartup method. The Exit event is fired when an application is shutting down. This event is raised by the OnExit method. Enum for ShutdownMode Enum for ReasonSessionEnding Container for the event handlers EventHandlersStore is a hashtable of handlers for a given EventPrivateKey or RoutedEvent Constructor for EventHandlersStore Adds a routed event handler for the given RoutedEvent to the store Container for the route to be followed by a RoutedEvent when raised EventRoute constitues a non-null and an ordered list of (target object, handler list) pairs It facilitates adding new entries to this list and also allows for the handlers in the list to be invoked Constructor for given the associated Non-null to be associated with this Adds this handler for the specified target to the route NOTE: It is not an error to add a handler for a particular target instance twice (handler will simply be called twice).

Constructs a new instance of the DispatcherFrame class. Indicates whether or not this frame will exit when all frames are requested to exit.

Dispatcher frames typically break down into two categories: 1) Long running, general purpose frames, that exit only when told to. These frames should exit when requested. 2) Short running, very specific frames that exit themselves when an important criteria is met. These frames may consider not exiting when requested in favor of waiting for their important criteria to be met. These frames should have a timeout associated with them.
