&gt;<br>
&gt; How do you do this with PyQt?<br>
<br>
One way is to take advantage of the fact that the splash screen is just<br>
a widget. You can just create a progress bar as a child widget and update<br>
that.<br>
<br>
For example:<br>
<br>
app = QApplication(sys.argv)<br>
<br>
# Create a pixmap - not needed if you have your own.<br>
pixmap = create_pixmap(480, 320)<br>
<br>
splash = QSplashScreen(pixmap)<br>
progressBar = QProgressBar(splash)<br>
progressBar.setGeometry(splash.width()/10, 8*splash.height()/10,<br>
 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; \
&nbsp;8*splash.width()/10, splash.height()/10)<br> splash.show()<br>
<br>
for i in range(0, 100):<br>
 &nbsp; &nbsp;progressBar.setValue(i)<br>
<br>
 &nbsp; &nbsp;# Do something which takes some time.<br>
 &nbsp; &nbsp;t = time.time()<br>
 &nbsp; &nbsp;while time.time() &lt; t + 0.1:<br>
 &nbsp; &nbsp; &nbsp; &nbsp;app.processEvents()<br>
<br>
<br>
I hope this is enough to help you get started.<br>
<br>
