[v3] Event emitter blocks menu button press #4424
Description
Description
After the first event emit About button in below example no longer works. If I remove/comment out the goroutine to emit events button works as expected.
// Create a goroutine that emits an event containing the current time every second.
// The frontend can listen to this event and update the UI accordingly.
go func() {
for {
ps, err := monitor.GetProcesses()
if err != nil {
log.Fatal(err)
}
app.Event.Emit("ps", ps)
time.Sleep(3 * time.Second)
}
}()
menu := app.NewMenu()
helpMenu := menu.AddSubmenu("Help")
about := helpMenu.Add("About")
about.OnClick(func(ctx *application.Context) {
log.Println("ok")
notifier.SendNotification(notifications.NotificationOptions{
ID: "unique-id",
Title: "New Calendar Invite",
Subtitle: "From: Jane Doe", // Optional
Body: "Tap to view the event",
Data: map[string]interface{}{
"sender": "[email protected]",
"timestamp": "2025-03-10T15:30:00Z",
},
})
//dialog := application.InfoDialog()
//dialog.SetTitle("Welcome")
//dialog.SetMessage("Welcome to our application!")
//dialog.SetMessage("Welcome to our application!")
//dialog.Show()
app.Menu.ShowAbout()
})
// Create a new window with the necessary options.
// 'Title' is the title of the window.
// 'Mac' options tailor the window when running on macOS.
// 'BackgroundColour' is the background colour of the window.
// 'URL' is the URL that will be loaded into the webview.
window := app.Window.NewWithOptions(application.WebviewWindowOptions{
Title: "Window 1",
Mac: application.MacWindow{
InvisibleTitleBarHeight: 50,
Backdrop: application.MacBackdropTranslucent,
TitleBar: application.MacTitleBarHiddenInset,
},
// BackgroundColour: application.NewRGB(27, 38, 54),
URL: "/",
})
window.SetMenu(menu)
