Fpgui and lcl and qt, what are the advantages and disadvantages?

Question

Lazarus Ide can use several gui libraries. I am on Windows. I wonder what the difference is between them ... Clearly, lcl is the most stable.

Why would anyone use Qt and fpgui if they are of good quality?

Answer 1

LCL is an abstraction. IOW bulk LCL runs on all platforms. This is a bit Windows oriented as it is based on the basic principles (and compatibility) of a centralized VCL from Delphi Windows.
