I've seen this one come up before, and have seen some similar libraries mentioned. I would like to know what is the best cross-platform GUI builder for C/C++. I have quite a bit of experience now with the Win32 API in C, but would like to move onto using the power of C++, but feel that it wouldn't be quite right to simply use the (mostly) non-objective, C-targeted Win32 API or the bloating MFC.
Primarly I'm looking for platform-indepence, good documenation, a rich library and to a large extent, native resemblance.
I am right in looking for a widget toolkit as a solution? So far, I've researched GTK+, GTKmm, Qt, MFC, FLTK, wxWidgets and a few others from Widget Toolkits. What I found so far is that wxWidgets seems to meet all requirements the best, so I'm wondering if anyone has any pros/cons to add to this, or suggestions for other toolkits libraries.
