The point is specified in root coordinates with \fIrootX\fR and \fIrootY\fR (if a virtual-root window manager is in use then \fIrootX\fR and \fIrootY\fR are in the coordinate system of the virtual root window). The return value from the procedure is a token for the window that contains the given point. If the point is not in any window, or if the containing window is not in the same application as \fItkwin\fR, then NULL is returned. .PP The containing window is decided using the same rules that determine which window contains the mouse cursor: if a parent and a child both contain the point then the child gets preference, and if two siblings both contain the point then the highest one in the stacking order (i.e. the one that's visible on the screen) gets preference. .SH KEYWORDS containing, coordinates, root window /table>

+Qt comes with a large range of standard widgets that users of modern
+applications have come to expect.
+
+You can also develop your own custom widgets and controls, and use them
+alongside standard widgets.
+
+It is even possible to provide custom styles and themes for widgets that can
+be used to change the appearance of standard widgets and appropriately
+written custom widgets.
+
+
+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.
