From 6d4900a832e4506eb7daf1318332eec2a05282f1 Mon Sep 17 00:00:00 2001 From: Lea Anthony Date: Tue, 5 Aug 2025 09:20:19 +1000 Subject: [PATCH] ## Summary I've successfully implemented Windows Jumplists for Wails v3 with the following features: ### 1. **Windows Implementation** (`jumplist_windows.go`) - Full COM interface implementation for ICustomDestinationList, IShellLink, IPropertyStore, and IObjectCollection - Support for custom categories and tasks - Runtime configuration capabilities - Proper error handling and cleanup ### 2. **Cross-Platform Stubs** - Created stub implementations for macOS (`jumplist_darwin.go`) and Linux (`jumplist_linux.go`) - These are no-ops that prevent compilation errors on non-Windows platforms ### 3. **API Integration** - Added `CreateJumpList()` method to the main App struct - Platform-specific dispatch to the correct implementation ### 4. **Example Application** - Created a complete example in `v3/examples/jumplist/` - Demonstrates custom categories, tasks, and runtime configuration - Includes comprehensive documentation ### Key Features: - **Custom Categories**: Applications can create named categories like "Recent Documents" - **Tasks**: Common application tasks that appear at the bottom of the jump list - **Runtime Configuration**: Jump lists can be updated at any time during application execution - **Cross-Platform Safe**: The API gracefully handles non-Windows platforms ### Usage Example: ```go jumpList := app.CreateJumpList() jumpList.AddCategory(application.JumpListCategory{ Name: "Recent Files", Items: []application.JumpListItem{ { Type: application.JumpListItemTypeTask, Title: "Document.txt", FilePath: "path/to/app.exe", Arguments: "--open Document.txt", }, }, }) jumpList.Apply() ``` The implementation follows Windows jumplist specifications and integrates seamlessly with the existing Wails v3 architecture. --- v3/examples/jumplist/README.md | 101 +++++ v3/examples/jumplist/assets/index.html | 84 ++++ v3/examples/jumplist/main.go | 107 +++++ v3/pkg/application/application.go | 17 + v3/pkg/application/jumplist_darwin.go | 53 +++ v3/pkg/application/jumplist_linux.go | 53 +++ v3/pkg/application/jumplist_windows.go | 547 +++++++++++++++++++++++++ 7 files changed, 962 insertions(+) create mode 100644 v3/examples/jumplist/README.md create mode 100644 v3/examples/jumplist/assets/index.html create mode 100644 v3/examples/jumplist/main.go create mode 100644 v3/pkg/application/jumplist_darwin.go create mode 100644 v3/pkg/application/jumplist_linux.go create mode 100644 v3/pkg/application/jumplist_windows.go diff --git a/v3/examples/jumplist/README.md b/v3/examples/jumplist/README.md new file mode 100644 index 000000000..1884bbca1 --- /dev/null +++ b/v3/examples/jumplist/README.md @@ -0,0 +1,101 @@ +# Windows Jump List Example + +This example demonstrates how to implement Windows Jump Lists in a Wails v3 application. + +## What are Jump Lists? + +Jump Lists are a Windows feature introduced in Windows 7 that provide quick access to recently opened files and common tasks.

Windows Jump List Example

+

This example demonstrates how to use Windows Jump Lists in a Wails v3 application.

+ +
+

What are Jump Lists?

+

Jump Lists are a Windows feature that provide quick access to recent documents and common tasks. + They appear when you right-click on a taskbar button or hover over it in Windows 7 and later.

+
+ +

How to test:

+
    +
  1. Make sure this application is pinned to your Windows taskbar
    2. +
  2. Right-click on the taskbar icon
    3. +
  3. You should see custom categories and tasks in the jump list
    4. +
+ +

Features demonstrated:

+ + +
+

Note:

+

Jump Lists are a Windows-specific feature. On macOS and Linux, the jump list API calls + are no-ops and will not cause any errors.
