CanMaximize Property

Enables or disables maximizing the window.

public bool CanMaximize { get; set; }

Remarks

When Avalonia.Controls.Window.CanResize is false, this property is always false.

On macOS, setting this property to false also disables the full screen mode.

This property might be ignored by some window managers on Linux.

CanMinimize Property

Enables or disables minimizing the window.

public bool CanMinimize { get; set; }

Remarks

This property might be ignored by some window managers on Linux.

CanResize Property

Enables or disables resizing of the window.

public bool CanResize { get; set; }

ClosingBehavior Property

Gets or sets a value indicating how the Avalonia.Controls.Window.Closing event behaves in the presence of child windows.

public Avalonia.Controls.WindowClosingBehavior ClosingBehavior { get; set; }

ExtendClientAreaTitleBarHeightHint Property

Gets or Sets the TitlebarHeightHint for when the client area is extended. A value of -1 will cause the titlebar to be auto sized to the OS default. Any other positive value will cause the titlebar to assume that height.

public double ExtendClientAreaTitleBarHeightHint { get; set; }

ExtendClientAreaToDecorationsHint Property

Gets or sets if the ClientArea is Extended into the Window Decorations (chrome or border).

public bool ExtendClientAreaToDecorationsHint { get; set; }

Icon Property

Gets or sets the icon of the window.

public Avalonia.Controls.WindowIcon Icon { get; set; }

IsDialog Property

Gets whether this window was opened as a dialog

public bool IsDialog { get; set; }

IsExtendedIntoWindowDecorations Property

Gets if the ClientArea is Extended into the Window Decorations.

public bool IsExtendedIntoWindowDecorations { get; set; }

OffScreenMargin Property

Gets the window margin that is hidden off the screen area. This is generally only the case on Windows when in Maximized where the window border is hidden off the screen. This Margin may be used to ensure user content doesnt overlap this space.

public Avalonia.Thickness OffScreenMargin { get; set; }

OwnedWindows Property

Gets a collection of child windows owned by this window.

public System.Collections.Generic.IReadOnlyList<Avalonia.Controls.Window> OwnedWindows { get; set; }

PlatformImpl Property

Gets the platform-specific window implementation.

public Avalonia.Platform.IWindowImpl PlatformImpl { get; set; }

Position Property

Gets or sets the window position in screen coordinates.

public Avalonia.PixelPoint Position { get; set; }

ShowActivated Property

Gets or sets a value that indicates whether a window is activated when first shown.

public bool ShowActivated { get; set; }

ShowInTaskbar Property

Enables or disables the taskbar icon

public bool ShowInTaskbar { get; set; }

SizeToContent Property

Gets or sets a value indicating how the window will size itself to fit its content.

public Avalonia.Controls.SizeToContent SizeToContent { get; set; }

Remarks

If Avalonia.Controls.Window.SizeToContent has a value other than Avalonia.Controls.SizeToContent.Manual, Avalonia.Controls.Window.SizeToContent is automatically set to Avalonia.Controls.SizeToContent.Manual if a user resizes the window by using the resize grip or dragging the border.

NOTE: Because of a limitation of X11, Avalonia.Controls.Window.SizeToContent will be reset on X11 to Avalonia.Controls.SizeToContent.Manual on any resize - including the resize that happens when the window is first shown. This is because X11 resize notifications are asynchronous and there is no way to know whether a resize came from the user or the layout system. To avoid this, consider setting Avalonia.Controls.Window.CanResize to false, which will disable user resizing of the window.

SystemDecorations Property

public Avalonia.Controls.WindowDecorations SystemDecorations { get; set; }

Title Property

Gets or sets the title of the window.

public string Title { get; set; }

WindowDecorationMargin Property
