[edit] Pourquoi utiliser Qt Creator

KDE4's ktimetracker loaded as QtCreator project

Pour créer votre application C++ vous pourriez utiliser n'importe quel éditeur de texte. Mais les possibilités de Qt Creator vont grandement vous faciliter la vie. Par exemple

  • vous pouvez charger un code sauvegardé, compiler et executer en un clic
  • vous aurez la completion de code
  • vous pouvez retrouver tous les endroits dans votre code ou vous appelez une fonction (e.g. "où est-ce que j'appelle la fonction refresh()")
  • vous pouvez retourner à une position de curseur plus récente avec votre éditeur, même dans un autre fichier
  • vous pouez checkout et commit vers des dépots Subversion or Git sans même quitter votre environnement

[edit] Créer un nouveau programme

Voici un exemple simple de création d'un "Hello World". Pour plus d'informations lire user documentation.

Étape 0

Lancer QtCreator

qtcreator

Puis sélectionnez Nouveau fichier ou projet -> Applications -> Application graphique Qt -> Nom = helloworld -> Suivant -> Suivant -> Terminer

Step 1

Select Edit -> Forms -> mainwindow.ui. Add the widgets you want by drag-and-drop:

Designer-step1.png

Step 2

Select the mainwindow. This is the one un-intuitive step. To lay out the objects in the mainwindow, you do not select the objects in the mainwindow, but the mainwindow itself.

Designer-step2.png

Step 3

Select Form -> Lay Out in a Grid

Designer-step3.png

Résultat

Vous obtenez un aspect convenable , et si vous redimensionnez la fenêtre, les widgets seront redimensionnés aussi.

[edit] Utiliser les librairies KDE

To use KDE classes like KMessageBox, you need to tell QtCreator to use the KDE libraries when building. Go to your home directory, change into yourproject and modify yourproject.pro. Add the line

LIBS += -lkdeui

Then you can start using KDE classes in your code.

[edit] Ajouter une barre d'outils

To add a toolbar, right-click on the UI and choose "Add Toolbar". Then you can set icons and text in your mainwindow's constructor with code like this:

ui->toolBar->addAction(QIcon("/usr/share/icons/oxygen/22x22/apps/ktip.png"),"hello world");

More Info...

[edit] Charger un projet existant

This describes how to use QtCreator to integrate existing KDE 4 applications. It has been tested with QtCreator 1.2.80 and SUSE Linux 11.1 but should work same or similar with every combination. As an example KDE application we use ktimetracker from the kdepim module, other applications should work likewise.

You can either work with code on your disk or have QtCreator do the repository checkout.

[edit] Utiliser un code local

  • import the CMakeLists.txt file (File -> Open -> kdepim/CMakeLists.txt)
  • as build directory choose kdepim
  • you will automatically come to a screen where you can run CMake
  • continue with the step "Run cmake"

[edit] Utiliser QtCreator pour faire un checkout d'un dépôt Git

  • choose File -> New File or Project -> Project from Version Control -> Git Repository Clone.
  • enter a Git URL like git@git.kde.org:/kdepim
  • accept kdepim as checkout directory
  • type finish, see how the checkout starts
noframe
 
Note
If the checkout fails with the message "remote host hung up unexpectedly" do a checkout from konsole. You may have to accept git.kde.org's fingerprint.
  • you will automatically come to a screen where you can run CMake
  • continue with the step "Run cmake"

[edit] Utiliser QtCreator pour faire un checkout d'un dépôt subversion

  • choose File -> New File or Project -> Version Control -> Subversion Checkout.
  • enter a Subversion URL like svn://anonsvn.kde.org/home/kde/trunk/KDE/kdepim
  • enter a checkout directory, i.e. the local directory where the code will be checked-out to
  • type finish, see how the checkout starts
  • you will automatically come to a screen where you can run CMake
  • continue with the step "Run cmake"

[edit] Lancer cmake

  • enter arguments for CMake like
/root/kdepim -DCMAKE_INSTALL_PREFIX=/usr/local -DLIB_SUFFIX=64 -DCMAKE_BUILD_TYPE=debugfull

DLIB_SUFFIX=64 means that you want to install your libraries into directories named lib64, not lib. /root/kdepim is where your source code is.

  • click "Run cmake"
  • note: a .cbp file is created containing many information about the build
  • click "Finish"

[edit] Build it

  • configure QtCreator to build only ktimetracker:

Projects -> Active run configuration=ktimetracker -> build settings -> build steps -> make -> show details -> activate ktimetracker.

  • configure QtCreator to use 8 logical processors:

Projects -> Active run configuration=ktimetracker -> build settings -> build steps -> make -> show details -> addtional Arguments = -j8

  • choose Build -> Build All
