Jiří Polášek 4d3c223402 CmdPal: Fix grid views (#43991)
## Summary of the Pull Request

This PR fixes the crash due to binding to a trimmed property. For this
it converts runtime bindings on GridView to use `{x:Bind}` so this issue
can't happen in the future.

- Fixes a crash related to the `Visibility` property in gallery/grid
views when trimmed during AOT builds.
- Fixes ShowTitle and ShowSubtitle properties, they are now taken into
account in a view.
- Improves UI layout, removes some margins and maches the corner radius
of the item contaienr with the item content in the gallery view.
- Refactores gallery and grid views to move logic from the view to the
view model so we can x:Bind to them.
- Replaces `{Binding}` with `{x:Bind}` to improve performance and enable
compile-time binding validation.
- Properties related to grids are splatted on to the common
`IGridPropertiesViewModel` interface. Subclassing would add extra
overhead without substential benefit.
- Adds new samples to showcase various grid view configurations.

cmdpal logo Command Palette

Windows Command Palette ("CmdPal") is the next iteration of PowerToys Run. With extensibility at its core, the Command Palette is your one-stop launcher to start anything.

By default, CmdPal is bound to Win+Alt+Space.

Creating an extension

The fastest way to get started is just to run the "Create extension" command in the palette itself. That'll prompt you for a project name and a Display Name, and where you want to place your project. Then just open the sln it produces. You should be ready to go 🙂.

The official API documentation can be found on this docs site.

We've also got samples, so that you can see how the APIs in-action.

[!info] The Command Palette is currently in preview. Many features of the API are not yet fully implemented. We may introduce breaking API changes before CmdPal itself is v1.0.0

Building CmdPal

Install & Build PowerToys

  1. Follow the install and build instructions for PowerToys

Load & Build

  1. In Visual Studio, in the Solution Explorer Pane, confirm that all of the files/projects in src\modules\CommandPalette and src\common\CalculatorEngineCommon do not have (unloaded) on the right side
    1. If any file has (unloaded), right click on file and select Reload Project
  2. Now you can right click on one of the project below to Build and then Deploy:

Projects of interest are:

  • Microsoft.CmdPal.UI: This is the main project for CmdPal. Build and run this to get the CmdPal.
  • Microsoft.CommandPalette.Extensions: This is the official extension interface.
    • This is designed to be language-agnostic. Any programming language which supports implementing WinRT interfaces should be able to implement the WinRT interface.
  • Microsoft.CommandPalette.Extensions.Toolkit: This is a C# helper library for creating extensions. This makes writing extensions easier.
  • Everything under "SampleExtensions": These are example plugins to demo how to author extensions. Deploy any number of these, to get a feel for how the extension API works.
