+Qt is provided with a comprehensive canvas through the GraphicsView
+classes.
+
+These examples demonstrate the fundamental aspects of canvas programming
+with Qt.
+
+
+The example launcher provided with Qt can be used to explore each of the
+examples in this directory.
+
+Documentation for these examples can be found via the Tutorial and Examples
+link in the main Qt documentation.
+
+
+Finding the Qt Examples and Demos launcher
+==========================================
+
+On Windows:
+
+The launcher can be accessed via the Windows Start menu. Select the menu
+entry entitled "Qt Examples and Demos" entry in the submenu containing
+the Qt tools.
+
+On Mac OS X:
+
+For the binary distribution, the qtdemo executable is installed in the
+/Developer/Applications/Qt directory. For the source distribution, it is
+installed alongside the other Qt tools on the path specified when Qt is
+configured.
+
+On Unix/Linux:
+
+The qtdemo executable is installed alongside the other Qt tools on the path
+specified when Qt is configured.
+
+On all platforms:
+
+The source code for the launcher can be found in the demos/qtdemo directory
+in the Qt package. This example is built at the same time as the Qt libraries,
+tools, examples, and demonstrations.
