#QT CREATOR WINDOWS CODE#
All we do is create a QApplication and then a Widget (this is our custom widget that we layed out in designer and added custom behaviour to in code with the name() and setName() functions). This is what the application looks like when it is executed:Īs you can see the main() function is very simple. You will see some compiler messages go past in the "Compile Output" panel at the bottom whilst building. Now build (Hammer icon in lower left or default shortcut of Ctrl-Shift-B) and run the application (green "play" icon in lower left corner). Up and running: Building and running the application Void Widget::setName(const QString &name) Now open up the widget.h file and edit it so that it looks like this: Just close it we are done with it for now. You will probably see the raw xml content of the UI file at this point. Change the text to "My name is:"Ĭlick on the Edit mode button in the left hand panel of creator to switch back to the text editor. The layout will take care of resizing your widgets for you if the parent widget's size changes.ĭouble click on the Label and it will switch to edit mode. In the toolbar at the top click on the "Lay out Horizontally" button or press Ctrl-H to add all widgets to a horizontal layout. The exact position is not important.Ĭlick on the widget background so that both of your new widgets (the label and line edit) get deselected. Using the toolbox on the left, drag a Label onto the widget formĭo similarly for a Line Edit and place it to the right of the Label. We will edit the widget.ui file first so:Ĭlick on that and designer will switch to design mode and open up the file. Learning to crawl: Editing the project files The above will create you a simple project consisting of four files: Select the base class to be QWidget (leave the class name as Widget which is the default).Ĭheck project creation options on summary and click "Finish". A desktop build is fine for this tutorial. Select one or more versions of Qt to target. Go to File - New File or Project menu entryĬhoose Qt Gui Application and choose a name for it:Įnter a project name, "qt-tutorial-01", say. Let's try making a trivial application that has a single window that shows a QLabel and a QLineEdit. The open source downloads can be found on the qt.io website here.įor commercial use consider getting a Qt Commercial license. If you are starting off you might want to consider the open source LGPL version. Grab yourself a copy of the Qt SDK or if you are on Linux the system-provided copy of Qt and a compiler.
#QT CREATOR WINDOWS INSTALL#
We will start off simple and build up in complexity as you get more familiar with the widgets and other facilities at your disposal.īefore you start: Download and install Qt and Qt Creator Once our basic application project is in place and running, we will go back and modify it to do some slightly useful things.
We will begin by creating a new Qt-based project and modifying the generated code to show a very simple graphical user interface (GUI). This is firmly intended as a gentle introduction to help beginners get up and running without scaring them.
