gurkengewuerz / cefgo Goto Github PK

Hello!

I found your cefgo project via your post on the go-ultralight issue tracker
maneac/go-ultralight#9 (comment)

I was doing some testing with Ultralight and noticed that some very simple Vue.js wasn't even working... Curious to see how CEF compares... Definitely excellent that it's actually open source!

I am trying to build the example on Ubuntu 20.04, but I'm getting a core dump...

I was able to get the release to build, though note the Readme.md says to use examples/main.go but I think it's updated to examples/mainthead/main.go.

go clean -cache -testcache && CGO_ENABLED=1 go build -o Release/test examples/mainthread/main.go

Once it builds though, I'm unable to get the test app to launch:

❯ ./test

[0904/203439.702504:ERROR:icu_util.cc(247)] Couldn't mmap icu data file
zsh: trace trap (core dumped)  ./test

I'm using:

cef_binary_85.3.1+g1306235+chromium-85.0.4183.83_linux64_minimal
go version go1.13.8 linux/amd64
Ubuntu 20.04.1 LTS (Focal Fossa)

I was looking through the release directory and it looks like the libcef.so that I downloaded is 1012 MB.... I'm surprised it's so big!

Is there a more compact version of this library?

I can see from the source and examples how to set the Width and Height of the browser window, but I don't see anything on setting the Top and Left position of the window...?

hi, the application will be crash in single-process mode while the memory usage over 3.5G, and the application will be blank in not single-process mode. so how to fix it?

Hey,

I have played with JS functions exposed in your example to affect the window and it worked fine, but when I tried from the side of GO, seems like it's not working. Added this code right after this line https://github.com/Gurkengewuerz/cefgo/blob/master/examples/mainthread/main.go#L72:

		time.AfterFunc(time.Second*5, func() {
			client.WindowHide()
		})

To hide the window after 5 seconds. Nothing happens, no error, nothing. Any ideas?
