Qt 5 and OpenCV 4 Computer Vision Projects

Setting up the UI

In the previous subsection, we designed the UI of our new application, Literacy. Now, let's create the Qt project for it and set up its full UI in a Qt main window.

First, let's create the project in the Terminal:

     $ mkdir Literacy/     $ cd Literacy/     $ touch main.cpp     $ ls     main.cpp     $ qmake -project     $ ls     Literacy.pro main.cpp     $

Then, we open the project file, Literacy.pro, and fill it with the following content:

     TEMPLATE = app     TARGET = Literacy     QT += core gui     greaterThan(QT_MAJOR_VERSION, 4): QT += widgets     INCLUDEPATH += .     # Input     HEADERS += mainwindow.h     SOURCES += main.cpp mainwindow.cpp

This is straightforward, as we have done this many times. However, it is still worth noting that we specify one header file and two source ...
