- \title Getting Started Programming with Qt Widgets
-
- In this topic, we teach basic Qt knowledge by implementing a simple Notepad
- application using C++ and the \l{Qt Widgets} module. The application is a
- small text editor which allows you to create a text file, save it, print it,
- or reopen and edit it again. You can also set the font to be used.
-
- \image notepad1.png "Notepad application"
-
- You can find the final Notepad source files in the qtdoc repository in the
- snippets/widgets-tutorial/notepad directory. You can either fetch
- the Qt 5 sources from Qt Project or install them as part of Qt 5.
-
- \section1 Creating the Notepad Project
-
- Setting up a new project in Qt Creator is aided by a wizard that guides you
- step-by-step through the project creation process. The wizard prompts you
- to enter the settings needed for that particular type of project and creates
- the project for you.
-
- \image notepad2.png "Qt Creator New File or Project dialog"
-
- To create the Notepad project, select \b File > \b{New File or Project} >
- \b Applications > \b {Qt Widgets Application} > \b Choose, and follow the
- instructions of the wizard. In the \b {Class Information} dialog, type
- \b Notepad as the class name and select \b QMainWindow as the base class.
-
- \image notepad3.png "Class Information Dialog"
-
- The \b {Qt Widgets Application} wizard creates a project that contains a main
- source file and a set of files that specify a user interface (Notepad
- widget):
-
- \list
- \li notepad.pro - the project file.
- \li main.cpp - the main source file for the application.
- \li notepad.cpp - the source file of the notepad class of the Notepad
- widget.
- \li notepad.h - the header file of the notepad class for the Notepad
- widget.
- \li notepad.ui - the UI form for the Notepad widget.
- \endlist
-
- The .cpp, .h, and .ui files come with the necessary boiler plate code for
- you to be able to build and run the project. The .pro file is complete.
- We will take a closer look at the file contents in the following sections.

- \li Here

- \li \l{Qt Creator: Tutorials}{Qt Creator Tutorials}
- \endtable
-
-
- \section1 Main Source File
-
- The wizard generates the following code in the main.cpp file:
-
- \snippet snippets/widgets-tutorial/notepad/main.cpp all
-
- We will go through the code line by line. The following lines include
- the header files for the Notepad widget and QApplication. All Qt classes
- have a header file named after them.
-
- \snippet snippets/widgets-tutorial/notepad/main.cpp 1
-
- The following line defines the main function that is the entry point for
- all C and C++ based applications:
-
- \snippet snippets/widgets-tutorial/notepad/main.cpp 2
-
- The following line creates a QApplication object. This object manages
- application-wide resources and is necessary to run any Qt program
- that uses Qt Widgets. It constructs an application object with \c argc
- command line arguments run in \c argv. (For GUI applications that do not
- use Qt Widgets, you can use QGuiApplication instead.)
-
- \snippet snippets/widgets-tutorial/notepad/main.cpp 3
-
- The following line creates the Notepad object. This is the object for
- which the wizard
- created the class and the UI file. The user interface contains visual
- elements that are called \c widgets in Qt. Examples of widgets are text
- edits, scroll bars, labels, and radio buttons. A widget can also be a
- container for other widgets; a dialog or a main application window, for
- example.
-
- \snippet snippets/widgets-tutorial/notepad/main.cpp 4
-
- The following line shows the Notepad widget on the screen in its own
- window. Widgets can also function as containers. An example of this
- is QMainWindow which often contains several types of widgets. Widgets
- are not visible by default; the function \l{QWidget::}{show()} makes
- the widget visible.
-
- \snippet snippets/widgets-tutorial/notepad/main.cpp 5
-
- The following line makes the QApplication enter its event loop. When a Qt
- application is running, events are generated and sent to the
- widgets of the application. Examples of events are mouse presses
- and key strokes.
-
- \snippet snippets/widgets-tutorial/notepad/main.cpp 6

- \li Widgets and Window Geometry
- \li \l{Window and Dialog Widgets}
- \row
- \li Events and event handling
- \li \l{The Event System}
- \endtable
-
- \section1 Designing a UI
-
- The wizard generates a user interface definition in XML format: notepad.ui.
- When you open the notepad.ui file in Qt Creator, it automatically opens
- in the integrated Qt Designer.
-
- When you build the application, Qt Creator launches the Qt
- \l{User Interface Compiler (uic)} that reads the .ui file and creates a
- corresponding C++ header file, ui_notepad.h.
-
- \section2 Using Qt Designer
-
- The wizard creates an application that uses a QMainWindow. It has its own
- layout to which you can add a menu bar, dock widgets, toolbars, and a
- status bar. The center area can be occupied by any kind of widget. The
- wizard places the Notepad widget there.
-
- To add widgets in Qt Designer:
-
- \list 1
- \li In the Qt Creator \b Editor mode, double-click the notepad.ui file
- in the \b Projects view to launch the file in the integrated Qt
- Designer.
- \li Drag and drop widgets Text Edit (QTextEdit) to the form.
- \li Press \b {Ctrl+A} (or \b {Cmd+A}) to select the widgets and click
- \b {Lay out Vertically} (or press \b {Ctrl+L}) to apply a vertical
- layout (QVBoxLayout).
- \li Press \b {Ctrl+S} (or \b {Cmd+S}) to save your changes.
- \endlist
-
- The UI now looks as follows in Qt Designer:
-
- \image notepad4.png
-
- You can view the generated XML file in the code editor:
-
- \quotefromfile snippets/widgets-tutorial/notepad/notepad.ui
-
- \printuntil QMenuBar
- \dots
-
- The following line contains the XML declaration, which specifies the XML
- version and character encoding used in the document:
-
- \code
- <?xml version="1.0" encoding="UTF-8"?>
- \endcode
-
- The rest of the file specifies an \c ui element that defines a Notepad
- widget:
-
- \code
- <ui version="4.0">
- \endcode
-
- The UI file is used together with the header and source file of the Notepad
- class. We will look at the rest of the UI file in the later sections.
-
- \section2 Notepad Header File
-
- The wizard generated a header file for the Notepad class that has the
- necessary #includes, a constructor, a destructor, and the Ui object. The
- file looks as follows:
-
- \snippet snippets/gs/notepad1.h all
-
- The following line includes QMainWindow that provides a main application
- window:
-
- \snippet snippets/gs/notepad1.h 1
-
- The following lines declare the Notepad class in the Ui namespace, which is the
- standard namespace for the UI classes generated from .ui files by the
- \c uic tool:
-
- \snippet snippets/gs/notepad1.h 2
-
- The class declaration contains the \c Q_OBJECT macro. It must come first in the class
- definition, and declares our class as a QObject. Naturally, it must also
- inherit from QObject. A QObject adds several abilities to a normal C++
- class. Notably, the class name and slot names can be
- queried at runtime. It is also possible to query a slot's
- parameter types and invoke it.
-
- \snippet snippets/gs/notepad1.h 3
-
- The following lines declare a constructor that has a default argument
- called \c parent.
- The value 0 indicates that the widget has no parent (it is a top-level
- widget).
-
- \snippet snippets/gs/notepad1.h 4
-
- The following line declares a virtual destructor to free the resources that were
- acquired by the object during its life-cycle. According to the C++
- naming convention, destructors have the same name as the class they are
- associated with, prefixed with a tilde (~). In QObject, destructors are
- virtual to ensure that the destructors of derived classes are invoked
- properly when an object is deleted through a pointer-to-base-class.
-
- \snippet snippets/gs/notepad1.h 5
-
- The following lines declare a member variable which is a pointer to the Notepad UI
- class. A member variable is associated with a specific class, and accessible
- for all its methods.
-
- \snippet snippets/gs/notepad1.h 6
-
- \section2 Notepad Source File
-
- The source file that the wizard generated for the Notepad class looks as
- follows:
-
- \snippet snippets/gs/notepad1.cpp all
-
- The following lines include the Notepad class header file that was generated
- by the wizard and the UI header file that was generated by the \c uic tool:
-
- \snippet snippets/gs/notepad1.cpp 0
-
- The following line defines the \c {Notepad} constructor:
-
- \snippet snippets/gs/notepad1.cpp 1
-
- The following line calls the QMainWindow constructor, which is the base
- class for the Notepad class:
-
- \snippet snippets/gs/notepad1.cpp 2
-
- The following line creates the UI class instance and assigns it to the
- \c ui member:
-
- \snippet snippets/gs/notepad1.cpp 3
-
- The following line sets up the UI:
-
- \snippet snippets/gs/notepad1.cpp 4
-
- In the destructor, we delete the \c ui:
-
- \snippet snippets/gs/notepad1.cpp 5
-
- In order to have the text edit field occupy the whole screen, we add
- \c setCentralWidget to the main window.
-
- \snippet snippets/widgets-tutorial/notepad/notepad.cpp 1
-
- \section2 Project File
-
- The wizard generates the following project file, \c {notepad.pro}, for us:
-
- \quotefile snippets/widgets-tutorial/notepad/notepad.pro
-
- The project file specifies the application name and the \c qmake template to
- use for generating the project, as well as the source, header, and UI files
- included in the project.
-
- You could also use \c qmake's \c -project option to generate the \.pro file. Although,
- in that case, you have to remember to add the line \c{QT += widgets} to the generated
- file in order to link against the Qt Widgets Module.

-
- \section1 Adding User Interaction
-
-
- To add functionality to the editor, we start by adding menu items and buttons on a toolbar.
-
- Click on "Type Here", and add the options New, Open, Save, Save as, Print
- and Exit. This creates 5 lines in the Action Editor below. To connect the
- actions to slots, right-click an action and select Go to slot > triggered(),
- and complete the code for that given slot.
-
- If we also want to add the actions to a toolbar, we can assign an icon
- to each QAction, and then drag the QAction to the toolbar. You assign an icon
- by entering an icon name in the Icon property of the action concerned. When the QAction
- has been dragged to the toolbar, clicking the icon will launch the associated
- slot.
-
- Complete the method \c on_actionNew_triggered() :
-
- \snippet snippets/widgets-tutorial/notepad/notepad.cpp 2
-
- \c current_file is a global variable containing the file presently being edited.
- It is defined in the private part of notepad.h:
-
- \snippet snippets/widgets-tutorial/notepad/notepad.h 6
-
- \c setText("") clears the text buffer.
-
- \section2 Opening a file
-
- In \c notepad.ui, right click on \c actionOpen and select \c {Go to slot}
-
- Complete method \c on_actionOpen_triggered().
-
- \snippet snippets/widgets-tutorial/notepad/notepad.cpp 3
-
- \c QFileDialog::getOpenFileName opens a dialog enabling you to select a file.
- QFile object \c myfile has the selected \c file_name as parameter.
- We store the selected file also into the global variable \c current_file for later purposes.
- We open the file with \c file.open as a readonly text file. If it
- cannot be opened, a warning is issued, and the program stops.
-
- We define a QTextStream \c instream for parameter \c myfile.
- The contents of file \c myfile is copied into QString \a text.
- \c setText(text) fille the buffer of our editor with \c text.
-
- \c section2 Saving a file
-
- We create the method for saving a file in the same way as for \l {Opening a file},
- by right clicking on \c actionSave, and selecting \c {Go to Slot}.
-
- \snippet snippets/widgets-tutorial/notepad/notepad.cpp 4
-
- QFile object \c myfile is linked to global variable \c current_file, the variable that
- contains the file we were working with.
- If we cannot open \c myfile, an error message is issued and the method stops.
- We create a QTextStream \c outstream. The contents of the editor buffer is converted
- to plain text, and then written to \c outstream.
-
- \c section2 Saving a file with \c {Save as}
-
- \snippet snippets/widgets-tutorial/notepad/notepad.cpp 5
-
- This is the same procedure as for \c {Saving a file}, the only difference
- being that here you need to enter a new file name for the file to
- be created.
-
-
- \section2 Print a file
-
- If you want to use print functionalities, you need to add \c printsupport to
- the project file:
-
- QT += core gui printsupport
-
- We declare a QPrinter object called \c printer.
- We launch a printer dialog box and store the selected printer in object \c printer.
- If we clicked on \c Cancel and did not select a printer, the methods returns.
- The actual printer command is given with \a ui->textEdit->print with our QPrinter
- object as parameter.
-
- \section2 Select a font
-
- \snippet snippets/widgets-tutorial/notepad/notepad.cpp 7
-
- We declare a boolean indicating if we did select a font with QFontDialog. If so, we
- set the font with \c ui->textEdit->setFont(myfont).
-
- \section2 Copy, cut, paste, undo, redo
-
- If you select some text, and want to copy it to the clipboard,
- you call the appropriate method of ui->textEdit. The same counts
- for cut, paste, undo, and redo.
-
- This table shows the method name to use.
-
- \table
- \header
- \li Task
- \li Method called
- \row
- \li Copy
- \li ui->textEdit->copy()
- \row
- \li Cut
- \li ui->textEdit->cut()
- \row

- \li ui->textEdit->paste()
- \row
- \li Undo
- \li ui->textEdit->undo()
- \row
- \li Redo
- \li ui->textEdit->redo()
- \endtable
-
- This project contains the following files:
-
- \list
- \li {main.cpp}
- \li {notepad.cpp}
- \li {notepad.h}
- \li {notepad.pro}
- \li {notepad.ui}

-
- \section1 Building and Running Notepad
-
- Now that you have all the necessary files, select \b Build >
- \b {Build Project Notepad} to build and run the application. Qt Creator
- uses \c qmake and \c make to create an executable in the directory
- specified in the build settings of the project and runs it.
-
- \section2 Building and Running from the Command Line
-
- To build the application from the command line, switch to the
- directory in which you have the \c .cpp file of the application and add the
- project file (suffixed .pro) described earlier. The following shell commands
- then build the application:
-
- \code
- qmake
- make (or nmake on Windows)
- \endcode
-
- The commands create an executable in the project directory. The \c qmake tool reads the
- project file and produces a \c Makefile with instructions on how to build the application.
- The \c make tool (or the \c nmake tool) then reads the \c Makefile and produces the executable
- binary.
