<div dir="ltr">Just guessing, I suspect you are adding spheres with each radius change.

<p>In render some things in the constructor of my GUI.<br>
<br>
Now I try to add some spheres and update/redraw the radius of the spheres every second.<br>
I have a text file containing the new radius of each sphere and a timer to generate the events.<br>
<br>
When I am changing a radius in the .txt file (while my program is executed) to a higher value, the sphere grows in real time.<br>
But when I <b>decrease</b> the radius, the sphere isn't decreasing. <br>
<br>
I think that my program doesn't update everything.<br>

<p><span>I use:<br>
<span>ui.qvtkWidget->update();</span></span><br>

</p>
<p>In my timer function everything (expect the renderer and renderwindow) is created each time.<br>
<br>
So I can't figure out whats the problem.<br>
