The that this event represents

The that this event represents.

When the application is passed a file to open.

When the application is passed a URI to open, protocol activation.

When the application is asked to reopen. An example of this is on MacOS when all the windows are closed, application continues to run in the background and the user clicks the application's dock icon.

When the application enters or leaves a background state. An example is when on MacOS the user hides or shows and application (not window), or when a browser application switchs tabs or when a mobile applications goes into the background.

Gets the arguments passed to the AppBuilder Start method.

Contains the arguments for the event.

Gets or sets the exit code that an application returns to the operating system when the application exits.

An event that is raised when the application is Deactivated for various reasons as described by the enumeration.

Tells the application that it should attempt to leave its background state. For example on OSX this would be [NSApp unhide]

true if it was possible and the platform supports this. false otherwise

Tells the application that it should attempt to enter its background state. For example on OSX this would be [NSApp hide]

The shutdown mode.

Gets or sets the main window of the application.

The main window.

Gets the list of all open windows in the application.

Raised by the platform when an application shutdown is requested.

Application Shutdown can be requested for various reasons like OS shutdown. On Windows this will be called when an OS Session (logout or shutdown) terminates. Cancelling the eventargs will block OS shutdown. On OSX this has the same behavior as on Windows and in addition: This event is raised via the Quit menu or right-clicking on the application icon and selecting Quit. This event provides a first-chance to cancel application shutdown; if shutdown is not canceled at this point the application will try to close each non-owned open window, invoking the event on each and allowing each window to cancel the shutdown of the application. Windows cannot however prevent OS shutdown.

Sent when the application is starting up.

Sent when the application is exiting.

Shuts down the application and sets the exit code that is returned to the operating system when the application exits.

An integer exit code for an application. The default exit code is 0.

Represents a control that enables a user to select a date by using a visual calendar display.

A Calendar control can be used on its own, or as a drop-down part of a DatePicker control. For more information, see DatePicker. A Calendar displays either the days of a month, the months of a year, or the years of a decade, depending on the value of the DisplayMode property. When displaying the days of a month, the user can select a date, a range of dates, or multiple ranges of dates. The kinds of selections that are allowed are controlled by the SelectionMode property. The range of dates displayed is governed by the DisplayDateStart and DisplayDateEnd properties. If DisplayMode is Year or Decade, only months or years that contain displayable dates will be displayed. Setting the displayable range to a range that does not include the current DisplayDate will throw an ArgumentOutOfRangeException. The BlackoutDates property can be used to specify dates that cannot be selected. These dates will be displayed as dimmed and disabled. By default, Today is highlighted. This can be disabled by setting IsTodayHighlighted to false. The Calendar control provides basic navigation using either the mouse or keyboard. The following table summarizes keyboard navigation. Key Combination DisplayMode Action ARROW Any Change focused date, unselect all selected dates, and select new focused date. SHIFT+ARROW Any If SelectionMode is not set to SingleDate or None begin selecting a range of dates. CTRL+UP ARROW Any Switch to the next larger DisplayMode. If DisplayMode is already Decade, no action. CTRL+DOWN ARROW Any Switch to the next smaller DisplayMode. If DisplayMode is already Month, no action. SPACEBAR Month Select focused date. SPACEBAR Year or Decade Switch DisplayMode to the Month or Year represented by focused item. XAML Usage for Classes Derived from Calendar If you define a class that derives from Calendar, the class can be used as an object element in XAML, and all of the inherited properties and events that show a XAML usage in the reference for the Calendar members can have the same XAML usage for the derived class. However, the object element itself must have a different prefix mapping than the controls: mapping shown in the usages, because the derived class comes from an assembly and namespace that you create and define. You must define your own prefix mapping to an XML namespace to use the class as an object element in XAML.

Gets or sets the currently selected date.

The date currently selected. The default is null. The given date is outside the range specified by and -or- The given date is in the collection. If set to anything other than null when is set to . Use this property when SelectionMode is set to SingleDate. In other modes, this property will always be the first date in SelectedDates.

Gets a collection of selected dates.

A object that contains the currently selected dates. The default is an empty collection. Dates can be added to the collection either individually or in a range using the AddRange method. Depending on the value of the SelectionMode property, adding a date or range to the collection may cause it to be cleared. The following table lists how CalendarSelectionMode affects the SelectedDates property. CalendarSelectionMode Description None No selections are allowed. SelectedDate cannot be set and no values can be added to SelectedDates. SingleDate Only a single date can be selected, either by setting SelectedDate or the first value in SelectedDates. AddRange cannot be used. SingleRange A single range of dates can be selected. Setting SelectedDate, adding a date individually to SelectedDates, or using AddRange will clear all previous values from SelectedDates. MultipleRange Multiple non-contiguous ranges of dates can be selected. Adding a date individually to SelectedDates or using AddRange will not clear SelectedDates. Setting SelectedDate will still clear SelectedDates, but additional dates or range can then be added. Adding a range that includes some dates that are already selected or overlaps with another range results in the union of the ranges and does not cause an exception.

The default is Today. To set this property in XAML, use a date specified in the format yyyy/mm/dd. The mm and dd components must always consist of two characters, with a leading zero if necessary. For instance, the month of May should be specified as 05.

Gets or sets the first date to be displayed.

The first date to display. To set this property in XAML, use a date specified in the format yyyy/mm/dd. The mm and dd components must always consist of two characters, with a leading zero if necessary. For instance, the month of May should be specified as 05.

Gets a collection of dates that are marked as not selectable.

A collection of dates that cannot be selected. The default value is an empty collection. Adding a date to this collection when it is already selected or adding a date outside the range specified by DisplayDateStart and DisplayDateEnd. Dates in this collection will appear as disabled on the calendar. To make all past dates not selectable, you can use the AddDatesInPast method provided by the collection returned by this property.

Gets or sets the last date to be displayed.

The last date to display. To set this property in XAML, use a date specified in the format yyyy/mm/dd. The mm and dd components must always consist of two characters, with a leading zero if necessary. For instance, the month of May should be specified as 05.

Provides positioning parameters to .

The IPopupPositioner provides a collection of rules for the placement of a a popup relative to its parent. Rules can be defined to ensure the popup remains within the visible area's borders, and to specify how the popup changes its position, such as sliding along an axis, or flipping around a rectangle. These positioner-created rules are constrained by the requirement that a popup must intersect with or be at least partially adjacent to its parent surface.

Set the size of the popup that is to be positioned with the positioner object, in device- independent pixels.

Specifies the anchor rectangle within the parent that the popup will be placed relative to, in device-independent pixels.

The rectangle is relative to the parent geometry and may not extend outside the window geometry of the popup's parent.

Defines the anchor point for the anchor rectangle.

The specified anchor is used derive an anchor point that the popup will be positioned relative to. If a corner anchor is set (e.g. 'TopLeft' or 'BottomRight'), the anchor point will be at the specified corner; otherwise, the derived anchor point will be centered on the specified edge, or in the center of the anchor rectangle if no edge is specified.

Defines in what direction a popup should be positioned, relative to the anchor point of the parent.

If a corner gravity is specified (e.g. 'BottomRight' or 'TopLeft'), then the popup will be placed towards the specified gravity; otherwise, the popup will be centered over the anchor point on any axis that had no gravity specified.

Specify how the popup should be positioned if the originally intended position caused the popup to be constrained.

Adjusts the popup position if the intended position caused the popup to be constrained; meaning at least partially outside positioning boundaries set by the positioner. The adjustment is set by constructing a bitmask describing the adjustment to be made when the popup is constrained on that axis. If no bit for one axis is set, the positioner will assume that the child surface should not change its position on that axis when constrained. If more than one bit for one axis is set, the order of how adjustments are applied is specified in the corresponding adjustment descriptions. The default adjustment is none.

Specify the popup position offset relative to the position of the anchor on the anchor rectangle and the anchor on the popup.

For example if the anchor of the anchor rectangle is at (x, y), the popup has the gravity bottom|right, and the offset is (ox, oy), the calculated surface position will be (x + ox, y + oy). The offset position of the surface is the one used for constraint testing. See set_constraint_adjustment. An example use case is placing a popup menu on top of a user interface element, while aligning the user interface element of the parent surface with some user interface element placed somewhere in the popup.

Defines how a popup position will be adjusted if the unadjusted position would result in the popup being partly constrained.

Whether a popup is considered 'constrained' is left to the positioner to determine. For example, the popup may be partly outside the target platform defined 'work area', thus necessitating the popup's position be adjusted until it is entirely inside the work area.

Don't alter the surface position even if it is constrained on some axis, for example partially outside the edge of an output.

Slide the surface along the x axis until it is no longer constrained.

First try to slide towards the direction of the gravity on the x axis until either the edge in the opposite direction of the gravity is unconstrained or the edge in the direction of the gravity is constrained. Then try to slide towards the opposite direction of the gravity on the x axis until either the edge in the direction of the gravity is unconstrained or the edge in the opposite direction of the gravity is constrained.

Slide the surface along the y axis until it is no longer constrained.

First try to slide towards the direction of the gravity on the y axis until either the edge in the opposite direction of the gravity is unconstrained or the edge in the direction of the gravity is constrained. Then try to slide towards the opposite direction of the gravity on the y axis until either the edge in the direction of the gravity is unconstrained or the edge in the opposite direction of the gravity is constrained.

Invert the anchor and gravity on the x axis if the surface is constrained on the x axis.

For example, if the left edge of the surface is constrained, the gravity is 'left' and the anchor is 'left', change the gravity to 'right' and the anchor to 'right'. If the adjusted position also ends up being constrained, the resulting position of the FlipX adjustment will be the one before the adjustment.

Invert the anchor and gravity on the y axis if the surface is constrained on the y axis.

For example, if the bottom edge of the surface is constrained, the gravity is 'bottom' and the anchor is 'bottom', change the gravity to 'top' and the anchor to 'top'. The adjusted position is calculated given the original anchor rectangle and offset, but with the new flipped anchor and gravity values. If the adjusted position also ends up being constrained, the resulting position of the FlipY adjustment will be the one before the adjustment.

Generates containers for an .

When creating a container for an item from a , the following process should be followed: - should first be called to determine whether the item needs a container. This method will return true if the item should be wrapped in a container control, or false if the item itself can be used as a container. - If returns true then the method should be called to create a new container, passing the recycle key returned from . - If the panel supports recycling and the recycle key is non-null then the recycle key should be recorded for the container (e.g. in an attached property or the realized container list). - method should be called for the container. - The container should then be added to the panel using - Finally, should be called. NOTE: If in the first step above returns false then the above steps should be carried out a single time: the first time the item is displayed. Otherwise the steps should be carried out each time a new container is realized for an item. When unrealizing a container, the following process should be followed: - If for the item returned false then the item cannot be unrealized or recycled. - Otherwise, should be called for the container - If recycling is supported by the panel and the container then the container should be added to a recycle pool keyed on the recycle key returned from . It is assumed that recycled containers will not be removed from the panel but instead hidden from view using e.g. `container.IsVisible = false`. - If recycling is not supported then the container should be removed from the panel. When recycling an unrealized container, the following process should be followed: - should be called to determine whether the item needs a container, and if so, the recycle key. - A container should be taken from the recycle pool keyed on the returned recycle key. - The container should be made visible. - method should be called for the container. - should be called. NOTE: Although this class is similar to that found in WPF/UWP, in Avalonia this class only concerns itself with generating and clearing item containers; it does not maintain a record of the currently realized containers, that responsibility is delegated to the items panel.

Determines whether the specified item needs to be wrapped in a container control.

The item to display. The index of the item. When the method returns, contains a key that can be used to locate a previously recycled container of the correct type, or null if the item cannot be recycled. true if the item needs a container; otherwise false if the item can itself be used as a container.

Creates a new container control.
