On: Ask HN: What's the best library for making cross-platform UIs?

[_ZeD_]

Obsolete. Nowadays qt libs are distributed on choice between commercial and lgpl

[marcosdumay → _ZeD_]

Some language bidings still come in GPL only.

[totocino → _ZeD_]

Don't you have to release the source code of your application if you don't want to pay?

[majewsky → totocino]

No. That's GPL, not LGPL.

[iamcreasy → totocino]

Not if you dynamically bind with qt libs. But yes you have to, if you statically bind with qt libs.
