QwtPlotMarker with "non-transparent" background?

Hi

This really feels like a question which I should not need to ask. Probably the answer is right in front of my nose... Anyhow, I have a couple of marker texts (QwtPlotMarker) in my plot and when two of them sometime partly overlap due to plot size etc, I would prefer to have one of them cover the other (in the overlapping area), instead of seeing the texts from both markers.

If I could make sure the markers have a (white) background and really have that backgound cover the other marker (which has a lower z-value), I would be really glad. I tried setting the backgound brush of the QwtText (which I use as marker label) to QBrush(Qt::white) but still I see the text from both markers even in the overlapping area. What am I missing?

Thanks in advance!

The following code results in a opaque white background for the text:

Code:

---

QwtText text( ... );
text.setBackgroundBrush( Qt::white );
 ...

Then all what's left is to adjust the z values of the plot items, so that the marker with the background is rendered on top of the other.
