Running widgets.go generates "MenuItemWidget has no field or method Shortcut" Error

[tataDan]

What happend?

If I create a new directory and copy examples/widgets.go to it, I get the "MenuItemWidget has no field or method Shortcut" error for line 49. Line 49 is g.MenuItem("Open").Shortcut("Ctrl+O"),.

However, if I run widgets.go directly from the clone of the repository, there is no error.

Code example

To Reproduce

1. Create a new directory
2. cd into that directory
3. run go mod init widgets
4. copy widgets.go from examples directory of the repository to this directory
5. go run widgets.go
6. might see the crash?

Version

(latest)

OS

Debian 12

What version is giu do you use in this external directory? In examples dir widgets.go is in module scope of giu clone, but somewhere else it probably usesa cached version from go cache. Try go get -u github.com/AllenDang/giu@master

[tataDan]

Initially this line was in my go.mod file: require github.com/AllenDang/giu v0.6.2.

After running go get -u github.com/AllenDang/giu@master that line is now require github.com/AllenDang/giu v0.6.3-0.20230825093324-3e09263b6d47.

Running that command removed the error and I can successfully run the application.

However, I still do not understand when I should use v0.6.2 and when I should use master.

I successfully ran several other of the examples programs using v0.6.2.

[gucio321]

It's just becauseShortcut method is present in master and isn't on 0.6.2 tag
