<br>
Is there anybody who knows how to connect polydata with QSlider?<br>
<br>
I'd tried to control polydata opacity with QSlider, but it didn't work.<br>
<br>
For connecting those two, i need to use 'connect' function.<br>
<br>
One of instances of 'connect' is receiver and it must be QObject.<br>
<br>
But i don't know how to transfer polydata(or only opacity value) to QObject.<br>
<br>
If you know the way, please reply.<br>
<br>
Thanks.<br>
<br>
Cheers<br>
Aleph<br>
