thansk nathan, i will try it out now. I am curious if anyone else has done this for windows, Linux, Android and IOS ?
I am working on building apps with golang and QT, and need to be able to do it cross platform. QT has aweful support for this, and i think a golang lib that does this, will allow all GUI toolkits using golang to benefit from this. i am willing to bring it al together into a single library that is agnostic to OS and wraps the special things each OS needs. Then from your golang code you just call the agnostic lib, I know this is a bit of a boiling the ocean idea, but the more i looked into it the more i found he differences between OS to be huge. Please let me knwo what you think ... joe On Monday, February 20, 2017 at 6:32:08 PM UTC+1, Nathan Kerr wrote: > > I managed to get this working. > > https://gist.github.com/nathankerr/38d8b0d45590741b57f5f79be336f07c > > I don't know what sort of app you are making, so I made a simple gui that > displays the url received, with some filler text before any are.
