Unfortunately you can't it is a bug in Qt.<br><br>You can take a look to the task tracker of Qt Number 231114 and 211500. I guess it is what you try to solve. The fix is in 4.4 branch (so scheduled for 4.4.4) and in 4.5. <br>
<br>As a workaround you have to manage the resize of your applet by hand when the size of the layout change.<br><div class="gmail_quote"><br>2008/12/30 Dong Tiger <span dir="ltr"><<a href="mailto:idlecat511@gmail.com">idlecat511@gmail.com</a>></span><br>

When this QGraphicsWidget's size changes, how to get the applet's size adjusted accordingly? <br>
<br>The code snippet looks like:<br>
<br> child = new MyGraphicsWidget(applet);<br> layout = new QGraphicsLinearLayout(applet);<br> layout->setSpacing(0);<br> layout->addItem(child);<br> applet->setLayout(layout);<br><br><br>Regards,<br>--<br>
