Avalonia.Win32

A Windows input method editor based on Windows Input Method Manager (IMM32).

Contains methods used to translate a Windows virtual/physical key to an Avalonia .

Indicates whether the key is an extended key, such as the right-hand ALT and CTRL keys. According to https://docs.microsoft.com/en-us/windows/win32/inputdev/wm-keydown.

Gets an Avalonia key from a Windows virtual-key and key data.

The Windows virtual-key. The key data (in the same format as lParam for WM_KEYDOWN). An Avalonia key, or if none matched.

Gets a Windows virtual-key from an Avalonia key.

The Avalonia key. A Windows virtual-key code, or 0 if none matched.

Gets a physical Avalonia key from a Windows virtual-key and key data.

The Windows virtual-key. The key data (in the same format as lParam for WM_KEYDOWN). An Avalonia physical key, or if none matched.

Gets a key symbol from a Windows virtual-key and key data.

The Windows virtual-key. The key data (in the same format as lParam for WM_KEYDOWN). A key symbol, or null if none matched.

The window handle. Fullscreen state.

Hides the window and activates another window.

Activates and displays a window. If the window is minimized, maximized, or arranged, the system restores it to its original size and position. An application should specify this flag when displaying the window for the first time.

Activates the window and displays it as a minimized window.

Activates the window and displays it as a maximized window.

Displays a window in its most recent size and position. This value is similar to , except that the window is not activated.

Activates the window and displays it in its current size and position.

Minimizes the specified window and activates the next top-level window in the Z order.

Displays the window as a minimized window. This value is similar to , except the window is not activated.

Displays the window in its current size and position. This value is similar to , except that the window is not activated.

Activates and displays the window. If the window is minimized, maximized, or arranged, the system restores it to its original size and position. An application should specify this flag when restoring a minimized window.

Sets the show state based on the value specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application.

Minimizes a window, even if the thread that owns the window is not responding. This flag should only be used when minimizing windows from a different thread.

Retrieve or update the attribute of the composition string.

Retrieve or update clause information of the composition string.

Retrieve or update the attributes of the reading string of the current composition.

Retrieve or update the clause information of the reading string of the composition string.

Retrieve or update the reading string of the current composition.

Retrieve or update the current composition string.

Retrieve or update the cursor position in composition string.

Retrieve or update the starting position of any changes in composition string.

Retrieve or update clause information of the result string.

Retrieve or update clause information of the reading string.

Retrieve or update the reading string.

Retrieve or update the string of the composition result.

Text format. Each line ends with a carriage return/linefeed (CR-LF) combination. A null character signals the end of the data. Use this format for ANSI text.

A handle to a bitmap

A memory object containing a BITMAPINFO structure followed by the bitmap bits.

Unicode text format. Each line ends with a carriage return/linefeed (CR-LF) combination. A null character signals the end of the data.

A handle to type HDROP that identifies a list of files.

The length of the structure, in bytes. Before calling the GetWindowPlacement or SetWindowPlacement functions, set this member to sizeof(WINDOWPLACEMENT). GetWindowPlacement and SetWindowPlacement fail if this member is not set correctly.

Specifies flags that control the position of the minimized window and the method by which the window is restored.

The current show state of the window.

The coordinates of the window's upper-left corner when the window is minimized.

The coordinates of the window's upper-left corner when the window is maximized.

The window's coordinates when the window is in the restored position.

Gets the default (empty) value.

Movement has occurred. Cannot be combined with TOUCHEVENTF_DOWN.

The corresponding touch point was established through a new contact. Cannot be combined with TOUCHEVENTF_MOVE or TOUCHEVENTF_UP.

A touch point was removed.

A touch point is in range. This flag is used to enable touch hover support on compatible hardware. Applications that do not want support for hover can ignore this flag.

Indicates that this TOUCHINPUT structure corresponds to a primary contact point. See the following text for more information on primary touch points.

When received using GetTouchInputInfo, this input was not coalesced.

The touch event came from the user's palm.

The small icon, but with the system theme variant rather than the window's own theme. Requested by other processes, e.g. the taskbar and Task Manager.

- ReleaseDC can only happen from the same thread that has called GetDC - When thread exits all of its windows and HDCs are getting destroyed - We need to create OpenGL context (require a window and an HDC) and render targets (require an HDC) from thread pool threads So this class hosts a dedicated thread for managing offscreen windows and HDCs for OpenGL

Windows 10 Anniversary Update

Custom Win32 window messages for the NotifyIcon

Gets the actual WindowsVersion. Same as the info returned from RtlGetVersion.

Window implementation for Win32 platform.

The Windows DPI which equates to a of 1.0.

Sets the transparency mica

Ported from https://github.com/chromium/chromium/blob/master/ui/views/win/fullscreen_handler.cc Method must only be called from inside UpdateWindowProperties.

Any WinRT API might not be available even if Windows version is supposed to support them (Win PE, Xbox...). Using ApiInformation is a typical solution in UWP/WinUI apps, so we should do as well.

Represents the rendering mode for platform graphics.

Avalonia is rendered into a framebuffer.

Enables ANGLE EGL for Windows with GPU rendering.

Avalonia would try to use native Widows OpenGL with GPU rendering.

Avalonia would try to use native Widows Vulkan with GPU rendering.

Represents the DPI Awareness for the application.

The application is DPI unaware.

The application is system DPI aware. It will query DPI once and will not adjust to new DPI changes

The application is per-monitor DPI aware. It adjust its scale factor whenever DPI changes.

Represents the Win32 window composition mode.

Render Avalonia to a texture inside the Windows.UI.Composition tree.

Supported on Windows 10 build 17134 and above. Ignored on other versions. This is recommended option, as it allows window acrylic effects and high refresh rate rendering.
Can only be applied with =.

Render Avalonia to a texture inside the DirectComposition tree.

Supported on Windows 8 and above. Ignored on other versions.
Can only be applied with =.

When is active, renders Avalonia through a low-latency Dxgi Swapchain.

Requires Feature Level 11_3 to be active, Windows 8.1+ Any Subversion. This is only recommended if low input latency is desirable, and there is no need for the transparency and styling / blurring offered by .
Can only be applied with =.

The window renders to a redirection surface.

This option is kept only for compatibility with older systems. Some Avalonia features might not work.

Platform-specific options which apply to Windows.

Embeds popups to the window when set to true. The default value is false.

Gets or sets Avalonia rendering modes with fallbacks. The first element in the array has the highest priority. The default value is: , .

If application should work on as wide range of devices as possible, at least add as a fallback value. Thrown if no values were matched.

Gets or sets Avalonia composition modes with fallbacks. The first element in the array has the highest priority. The default value is: , , .

If application should work on as wide range of devices as possible, at least add as a fallback value. Thrown if no values were matched.

When is set to , create rounded corner blur brushes If set to null the brushes will be created using default settings (sharp corners) This can be useful when you need a rounded-corner blurred Windows 10 app, or borderless Windows 11 app.

Render directly on the UI thread instead of using a dedicated render thread. Only applicable if is set to . This setting is only recommended for interop with systems that must render on the UI thread, such as WPF. This setting is false by default.

Windows OpenGL profiles used when is set to . This setting is 4.0 and 3.2 by default.

Provides a way to use a custom-implemented graphics context such as a custom ISkiaGpu. When this property set is ignored and only accepts null or .

Gets or sets the application's DPI awareness.
