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)
  • icuin49.dll (1.3MB)
  • icuuc49.dll (1MB)
  • Qt5Cored.dll (7MB)
  • Qt5Guid.dll (5.5MB)
  • Qt5Widgets.dll (4MB)
  • Qt5Widgetsd.dll (7.5MB)

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

  • Multiple version of Qt library
  • Keyboard shortcuts:
    • Ctrl + Click the symbol - move to the definition or the declaration of a symbol.
    • Click a symbol + Right click + Follow the symbol under cursor - move to the definition

Qt Tutorial

Qt Basic

  • To run Qt from command line, I use
# Open command prompt from Visual Studio 2010
set PATH=C:\Qt\Qt5.0.2\5.0.2\msvc2010_opengl\bin;%PATH%

Now we can build the project by for example 

cd C:\Qt\FQD\Chapter01\plain-cpp
qmake -project
qmake
nmake

The executable will be located under release subfolder. 

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.
