-------------------------------------------------------------------------------- 1 | # Win32 Xaml App Samples 2 | C++ samples that demonstrate basic Win32 use of Xaml using [DesktopWindowXamlSource](https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.hosting.desktopwindowxamlsource?view=winrt-20348), also known 3 | as Xaml Islands. 4 | 5 | * [Minimal](./Minimal/Win32XamlApp.cpp) - The app client area is all Xaml. The markup is stored as a string and parsed at runtime. 6 | Less that 150 lines of code with 50 of it being markup (the `NavigationView` stolen from Terminals Settings UI) 7 | 8 | ![Win32 Xaml App](Win32XamlApp.png) 9 | 10 | * [Multi Window App ](./MultiWindow/MultiWindowXamlApp.cpp) - A multi-window Win32 app that uses Xaml. This hooks up some 11 | handlers to the markups contents to demonstrate responding to Xaml originated events. 12 | 13 | ![Win32 Xaml App Multi Window](Win32XamlAppMultiWindow.png) 14 | 15 | * [Multi Xaml Mulit Window App](./MultiXamlAndWindow/MultiXamlAndWindowApp.cpp) - Multi window app that creates 2 islands in each window. Mostly a diagnostic case for testing. 16 | 17 | ## Limitations 18 | * Not using WinUI 2.x, using System Xaml instead. 19 | * Does not implement accelerator handling or any integration with Win32 UI (who wants to use Win32 UI anyway!). 20 | * Uses the system provided Xaml Application object, so no way to provide custom metadata. 21 | * Intellisense in the .xaml files is broken, VS is confused seeing a .xaml file in a Win32 app project type. 22 | 23 | ## Debugging tips 24 | Look in the debugger output window for Xaml parsing errors, it identifies line and offset of the error. 25 | 26 | ## Speical clone instructions 27 | Be sure to clone this repo with `--recurse-submodules` ([docs with details](http://git-scm.com/book/en/v2/Git-Tools-Submodules#Cloning-a-Project-with-Submodules)). 28 | Alternatively run `git submodule update --init` to use the Win32AppHelper submodule. 29 | 30 | `git clone --recurse-submodules https://github.com/ChrisGuzak/Win32XamlApp.git` 31 | 32 | -------------------------------------------------------------------------------- /win32_app.manifest: -------------------------------------------------------------------------------- 1 | 2 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | true/PM 17 | PerMonitorV2, PerMonitor 18 | 19 | 20 | 21 | --------------------------------------------------------------------------------
