the widgets it contains are automatically deleted.
- \section1 Creating a Window
+ \section1 Writing a main Function
+
+ Many of the GUI examples in Qt follow the pattern of having a \c{main.cpp}
+ file containing code to initialize the application, and a number of other
+ source and header files containing the application logic and custom GUI
+ components.
+
+ A typical \c main() function, written in \c{main.cpp}, looks like this:
+
+ \quotefile doc/src/snippets/widgets-tutorial/template.cpp
+
+ We first construct a QApplication object which is configured using any
+ arguments passed in from the command line. After any widgets have been
+ created and shown, we call QApplication::exec() to start Qt's event loop.
+ Control passes to Qt until this function returns, at which point we return
+ the value we obtain from this function.
+
+ In each part of this tutorial, we provide an example that is written
+ entirely within a \c main() function. In more sophisticated examples, the
+ code to set up widgets and layouts is written in other parts of the
+ example. For example, the GUI for a main window may be set up in the
+ constructor of a QMainWindow subclass.
+
+ The \l{Qt Examples#Widgets}{Widgets examples} are a good place to look for
+ more complex and complete examples and applications.
+
+ \section1 Building Examples and Tutorials
+
+ If you obtained a binary package of Qt or compiled it yourself, the
+ examples described in this tutorial should already be ready to run.
+ However, if you may wish to modify them and recompile them, you need to
+ perform the following steps:
+
+ \list 1
+ \o At the command line, enter the directory containing the example you
+ wish to recompile.
+ \o Type \c qmake and press \key{Return}. If this doesn't work, make sure
+ that the executable is on your path, or enter its full location.
+ \o On Linux/Unix and Mac OS X, type \c make and press \key{Return};
+ on Windows with Visual Studio, type \c nmake and press \key{Return}.
+ \endlist
+
+ An executable file should have been created within the current directory.
+ On Windows, this file may be located within a \c debug or \c release
+ subdirectory. You can run this file to see the example code at work.

Just as widgets can contain other widgets, layouts can be used to provide
different levels of grouping for widgets. Here, we want to display a
label alongside a line edit at the top of a window, above a table view
showing the results of a query.
+ We achieve this by creating two layouts: \c{queryLayout} is a QHBoxLayout

As well as QHBoxLayout and QVBoxLayout, Qt also provides QGridLayout
and QFormLayout classes to help with more complex user interfaces.

+ \section1 Setting up the Model
+
+ In the code above, we did not show where the table's data came from
