[9] Qt Designer is a tool for designing and building graphical user interfaces (GUIs) from Qt ...
Signals and slots is a language construct introduced in Qt [1] for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code. The concept is that GUI widgets , and other objects, can send signals containing event information which can be received by other objects using special member ...
It was designed to support large, complex projects, written in any number of programming languages, primarily C/C++. Qbs is an all-in-one tool that generates a build graph from a high-level project description (like its predecessor qmake ), and additionally undertakes the task of executing the commands in the low-level build graph (like make ).
Despite the immense popularity of Qt, there continues to be science software using the GUI widgets of version 2 of GTK toolkit. Whether this is going to remain that way, or whether the software will be ported to some current version of GTK (maybe GTK 4) remains to be seen. Ghemical – computational chemistry software package
