d863e525e3* ## Summary I've successfully fixed the nil pointer dereference bug in the Wails v3 system tray functionality on Windows. Here's what I addressed: **Root Cause**: The bug occurred in `systemtray_windows.go:80` where `*trayBounds = PhysicalToDipRect(*trayBounds)` was dereferencing a potentially nil pointer without checking. **Fixes Applied**: 1. **`positionWindow` method (lines 80-82)**: Added nil check for `trayBounds` before dereferencing 2. **`bounds` method (lines 121-123, 129-131)**: Added checks for uninitialized `hwnd` and nil return from `GetSystrayBounds` 3. **`iconIsInTrayBounds` method (lines 147-149, 155-157, 160-162)**: Added similar protective checks and taskbar position validation 4. **`getScreen` method (lines 173-175)**: Added `hwnd` initialization check 5. **`openMenu` method (lines 45-47)**: Added nil check for `trayBounds` **Key Improvements**: - Added proper initialization checks for `s.hwnd == 0` - Added nil pointer checks for all Windows API return values - Ensured graceful error handling instead of panics - Maintained existing functionality while preventing race conditions The fix addresses the race condition where system tray operations could be called before the tray was fully initialized, preventing the nil pointer dereference panic described in issue #4456. * Update changelog |

Introduction
The traditional method of providing web interfaces to Go programs is via a built-in web server. Wails offers a different approach: it provides the ability to wrap both Go code and a web frontend into a single binary. Tools are provided to make this easy for you by handling project creation, compilation and bundling. All you have to do is get creative!
Features
- Use standard Go for the backend
- Use any frontend technology you are already familiar with to build your UI
- Quickly create rich frontends for your Go programs using pre-built templates
- Easily call Go methods from Javascript
- Auto-generated Typescript definitions for your Go structs and methods
- Native Dialogs & Menus
- Native Dark / Light mode support
- Supports modern translucency and "frosted window" effects
- Unified eventing system between Go and Javascript
- Powerful cli tool to quickly generate and build your projects
- Multiplatform
- Uses native rendering engines - no embedded browser!

FAQ
-
Is this an alternative to Electron?
Depends on your requirements. It's designed to make it easy for Go programmers to make lightweight desktop applications or add a frontend to their existing applications. Wails does offer native elements such as menus and dialogs, so it could be considered a lightweight electron alternative.
-
Who is this project aimed at?
Go programmers who want to bundle an HTML/JS/CSS frontend with their applications, without resorting to creating a server and opening a browser to view it.
-
What's with the name?
When I saw WebView, I thought "What I really want is tooling around building a WebView app, a bit like Rails is to Ruby". So initially it was a play on words (Webview on Rails). It just so happened to also be a homophone of the English name for the Country I am from. So it stuck.
