Split from #3157, this PR focuses exclusively on letting the LWin/RWin to be used for opening flow. It is split so I can add this feature in while I work on the support for key combinations.

Source code for ChefKeys that handles the Win key operations in this change is available at https://github.com/jjw24/ChefKeys.

Most of this code is temporary and will be replaced by PR 3157.

Tested:

  • LWin can open flow
  • Can not use Win key as part of a combo (will be handled in the other PR)
  • Can only use the Win key for open Flow hotkey and not for other hotkey actions
  • Once Win key is not used ChefKeys is stopped.
  • ChefKeys is only started if Win key is used

Close #662, #2709, #1358

📝 Walkthrough

Walkthrough

The changes integrate a new dependency and extend hotkey management for specific Windows keys ("LWin" and "RWin"). A new package reference is added to the project file, and the hotkey handlers in the helper and UI classes are updated to register/unregister these keys using the ChefKeys library. Additionally, the hotkey availability logic in the UI components is refined, and the hotkey dialog now manages the blocking state of the start menu through ChefKeysManager.

Changes

File(s) Change Summary
Flow.Launcher/Flow.Launcher.csproj Added a new package reference: <PackageReference Include="ChefKeys" Version="0.1.2" />.
Flow.Launcher/Helper/HotKeyMapper.cs Added methods: OnToggleHotkeyWithChefKeys, SetWithChefKeys, and RemoveWithChefKeys to integrate ChefKeys functionality for "LWin" and "RWin" hotkeys.
Flow.Launcher/HotkeyControl.xaml.cs Updated SetHotkey to treat "LWin" and "RWin" as always available; retains the original validation for other keys.
Flow.Launcher/HotkeyControlDialog.xaml.cs Introduced a new static variable isOpenFlowHotkey and updated hotkey availability logic; modified Cancel and Save methods to call ChefKeysManager.Stop() and manage start menu blocking appropriately.

Poem

Hop along in lines of code,
I'm a rabbit with a festive mode,
ChefKeys now guide our keys so true,
"LWin" and "RWin" dance anew,
With carrots and bytes, we happily glide,
In this flow, no bug can hide!

    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.

38-60: ⚠️ Potential issue

Ensure ChefKeys cleanup in all exit paths.

The ChefKeys state is properly cleaned up in Cancel and Save methods, but not in case of exceptions. Consider using a try-finally block in the constructor.

     public HotkeyControlDialog(string hotkey, string defaultHotkey, IHotkeySettings hotkeySettings, string windowTitle = "")
     {

🧹 Nitpick comments (2)
Flow.Launcher/Helper/HotKeyMapper.cs (1)

40-50: Refactor duplicate Windows key checks.

The Windows key check logic is duplicated in both SetHotkey methods. Consider extracting this check into a private helper method.

+    private static bool IsWindowsKey(string hotkeyStr)
+    {
+        return hotkeyStr == "LWin" || hotkeyStr == "RWin";
+    }
+
     private static void SetHotkey(string hotkeyStr, EventHandler<HotkeyEventArgs> action)
     {
-        if (hotkeyStr == "LWin" || hotkeyStr == "RWin")
+        if (IsWindowsKey(hotkeyStr))
         {
             SetWithChefKeys(hotkeyStr);
             return;
         }
         // ... rest of the method
     }

     internal static void SetHotkey(HotkeyModel hotkey, EventHandler<HotkeyEventArgs> action)
     {
         string hotkeyStr = hotkey.ToString();
-        if (hotkeyStr == "LWin" || hotkeyStr == "RWin")
+        if (IsWindowsKey(hotkeyStr))
         {
             SetWithChefKeys(hotkeyStr);
             return;
         }
         // ... rest of the method
     }

Hi @Jack251970 have you had a look at this PR and is there anything I need to fix?

This looks good to me and I don’t have any changes to suggest. I also tested it with the installer, and it works as expected.👍
