Hi,
I have a voronoi pattren inside a circle. I somehow cannot get to fill inside the circle.

Hi.

Check this.

Actually, your object is a rectangle with no stroke, and the fill is a pattern (circle with voronoi). So the circle with voronoi you see, is not an object as such, but a pattern.
I have the impression that, in your specific drawing, the quickest way to fill the circle would be to draw a filled circle under it. The color of the circle in the back will be visible through the voronoi.

(As a side note, I have the impression you complicated things a bit. If you would have started with a circle, then Extension > Generate from path > Voronoi pattern, you wouldn't have nested patterns I think, and achieved the same result visually.)

Apart from that, Object > Pattern > Pattern to Object may be of interest to you? (I tried it on your drawing and had to do it repeatedly, as you seem to have nested patterns).
And also the bucket tool may be of use.

All depends on which strategy you choose and what you actually want to achieve exactly...

Hhmm....I don't see any nested patterns. But I am curious how you made it.

If I make a circle, and apply the Voronoi extension, it's still called a circle, with a stroke and a pattern fill. But yours....oh maybe this is what you did?

After you applied the extension, you must have done Object menu > Patterns > Object to Pattern. Because your whole entire circle is the pattern -- not just the Voronoi fill. And yes, if I convert my circle with the Voronoi fill to Pattern, it's now called a rectangle.

Maybe that's what bartovan meant with nested patterns?

Switch to the Node tool and drag the pattern. You can see that the whole circle with Voronoi is the pattern. My first clue is that even though you have quite an obvious stroke, the style indicator area shows no stroke. It's because converting it to a pattern changed it into a rectangle (technically).

Yep. I called it "nested" because I had to do several times "Pattern to object" in order to get to only objects, without any pattern. Maybe I didn't use the correct term...
