I am working on a project in c++. And I have to creat a gui interface for it.

Question

Please anyone share some link or pdf etc( any helping material) to learn how to gui in c++. I will be very grateful to you.

Answer 1

There are plenty of free portable GUI libraries and frameworks, each with its own strengths and weaknesses:
Qt :- https://www.qt.io/
Dear ImGui :- https://github.com/ocornut/imgui
GTKmm (based on GTK+) :- https://www.gtkmm.org/en/
wxWidgets :- http://www.wxwidgets.org/
FLTK :- https://www.fltk.org/
Ultimate++ :- https://www.ultimatepp.org/
JUCE :- https://juce.com/

Especially Qt has nice tutorials and tools which help you getting started in making gui but is a heavy tool to install. You can easily get the well explained documentations on their respective website or/and if you want video tutorials then you can always use YouTube for that.for example this one is very good video which starts from very basics of gui using wxwidgits👇
