wails3 provides an event system that allows for hooking into application and window events
|
|
|
|
```go
|
|
// Notification of application start
|
|
application.RegisterApplicationEventHook(events.Common.ApplicationStarted, func(event *application.ApplicationEvent) {
|
|
app.Logger.Info("Application started!")
|
|
})
|
|
```
|
|
|
|
```go
|
|
// Notification of system theme change
|
|
application.OnApplicationEvent(events.Common.ThemeChanged, func(event *application.ApplicationEvent) {
|
|
app.Logger.Info("System theme changed!")
|
|
if event.Context().IsDarkMode() {
|
|
app.Logger.Info("System is now using dark mode!")
|
|
} else {
|
|
app.Logger.Info("System is now using light mode!")
|
|
}
|
|
})
|
|
```
|
|
|
|
```go
|
|
// Disable window closing by canceling the event
|
|
window.RegisterHook(events.Common.WindowClosing, func(e *application.WindowEvent) {
|
|
app.Logger.Info("Window 1 Closing? Nope! Not closing!")
|
|
e.Cancel()
|
|
})
|
|
```
|
|
|
|
```go
|
|
// Notification of window focus
|
|
window.OnWindowEvent(events.Common.WindowFocus, func(e *application.WindowEvent) {
|
|
app.Logger.Info("[ApplicationEvent] Window focus!")
|
|
})
|
