Help to build uiktest

[Tuan Hoang Anh]

Hello

I built uiktest success but when I run main.exe, it only display "empty display string"

Please help me. Thanks in advance

The uiktest that you built unfortunately uses xgb as its protocol, so it's trying to connect to a (probably) nonexistant X server using a (certainly) nonexistant DISPLAY env var.

Unfortunately I don't have the spare time today to set it up for go.wde/win, but if you take a look at go.wde/win/wintest you might be able to figure it out.

You just need to modify uiktest to

 - import the win package,

 - set uik.WindowGenerator to a function that calls win.NewWindow(), and

 - ensure that win.HandleWndEvents() runs in the main goroutine.

At some point I hope to make swapping out backends a little more transparent.

[John Asmuth]

It's much easier to do this, now - uiktest should build on all three platforms easily. Only catch is that on os x you have to install the gomacdraw framework first.

Thanks for update go-uik.

But when i run new exe of uiktest, it have error. Here is error :

D:\GO\example\go-uik>main.exe

empty display string

throw: all goroutines are asleep - deadlock!

Please pull and try again. I fixed this a few days ago.

Issue was I used to load the xgb backend automatically in uik. On windows, this is a mistake!

Oh, I fixed this in response to your report.

Did you update the source properly? You can do this by running "go get -u github.com/skelterjohn/go.uik/..." and running it again. If that fails, clean it out and try again. This issue was definitely fixed.

in my practice, the error still as bellow:

Don't list source files. Just "go build".

[techabc]

after directly type "go build" in uiktest dir, I got uiktest.exe, but
I execute it still error:

Somewhere, someone is importing go.wde/xgb. There is a file in uiktest that does that, but it's wde_linux.go, so it shouldn't be included when you build on windows. Old versions of go.uik imported it, but I took that out. If you can figure out where go.wde/xgb is being imported, we'll find the reason why this is happening.

[Pavel Korotkov]

As far as I can see there is at least one place where go.wde/xgb is still used: https://github.com/skelterjohn/go.uik/blob/master/draw.go#L22.

Yikes! Mia culpa. I'll push a fix for that soon.

Hello, i'm new to golang, so sorry if this is a silly question.
I'm trying to run Hello World example. The go build of source doesn't raise any errors. But running the .exe causes this:

c:\Go\_proj>main
panic: no wde backend imported

goroutine 1 [running]:
github.com/skelterjohn/go%2ewde._func_001()

goroutine 4 [runnable]:

c:/Go/_proj/main.go:11 +0x22

I guess this is similar with problems discussed above in this thread.
Wuold you plese help to solve this.

Hi Sergey,

Add the following line to the top of one of your source files:

import _ "github.com/skelterjohn/go.wde/init"

That will register a window driver that should work for your platform. If it doesn't, then you might be on a strange platform!
