<h1 align=center> Setting the Application Icon</h1><br clear="all">
The application icon, typically displayed in the upper left corner of the
application top-level windows, can in Qt be set by using the
QWidget::setIcon() method on the top-level widgets.
<p>
However, in order to change the icon of the executable application file
itself, as it is presented on the desktop (i.e. prior to application
execution), it is necessary to employ another, platform-dependent
technique.
<p>
<h2>Setting the Application Icon on Windows</h2>
<p>
First, create an ICO format bitmap file that contains the icon image. This
can be done with e.g. Microsoft Visual C++: Select "File->New...", then
select the "File" tab in the dialog that appears, and choose "Icon". (Note
that you do not need to load your application into Visual C++; here we are
only using its icon editor).
<p>
Store the ICO file in the source code directory of your application, say
with the name "myappico.ico". Then, create a text file called
e.g. "myapp.rc", and let it contain this single line of text:
<p>
<pre>IDI_ICON1 ICON DISCARDABLE "myappico.ico"
</pre>
<p>
Lastly, assuming you are using tmake to generate your makefiles, add this
line to your "myapp.pro" file:
<p>
<pre>RC_FILE = myapp.rc
</pre>
<p>
Regenerate your makefile and your application. The .exe file will now be
represented with your icon in e.g. Explorer.
<p>
If you do not use tmake, the necessary steps are: First, run the "rc"
program on the .rc file, then link your application with the resulting
.res file.
