How to distribute Qt application

In my first example of GUI with button & label, I need to put 7 dll files in the same exe directory.

  • icudt49.dll (17MB)

  • Qt5Cored.dll (7MB)

How to Build static Qt on Windows

My experience based on Qt 5.0.2

  • read ReadME file to download perl, python and ruby. Make sure the executable path in in PATH env variable.
  • OpenGL requirement: DirectX SDK The 6/7/2010 version is about 572MB. This will be installed to C:\Program Files (x86)\Microsoft DirectX SDK(June 2010) directory.
  • modify mkspecs by searching qmake.conf. It was found in C:\Qt\qt-everwhere-opensource-src-5.0.2\qtbase\mkspecs\win32-msvc2010
  • configure -static -release -platform win32-msvc2010 -opengl desktop

Qt Creator

Qt Tutorial

Qt Basic

QLabel *label = new QLabel("ABCDE");
label->show();
// (*label).show();
  • Use :: to call a function from some class. For example,
QObject::connect();

means to use connect() function from QObject class.
