Example controlgallery compiles and runs without error, but no window is shown #13

Hi,

thanks a lot for these nice bindings.

I am new to Crystal and wanted to check out some options for UI libraries.

I have successfully compiled the controlgallery example, but when I run it from the command line, no UI window is opened. Strangely, there no errors either, and the programs just hangs:

$ crystal -v

The example controlgallery from Fusion/libui.cr works.

This is on Kubuntu 18.10 with Crystal 0.27.2

Do you have any ideas what might be going on?

Kind regards,
Axel

Hi @apahl, I am currently working on the rebuild branch of Hedron, which is a complete rewrite in order to improve both the base binding and HDML. I'll try and have a look at the issue, but I'm abandoning the base branch, so please look at the rebuild branch for any updates. Thanks!

@apahl The base branch examples have not been updated to support pull request #11 

gallery = ControlGallery.new
gallery.draw
gallery.start
gallery.close

@Qwerp-Derp Thanks, I will look into that branch. @Iainmon Thanks. With the patch it now works. Great!

Thanks to both of you for the quick answers!

Kind regards, Axel
