Let me see if I understood you correctly: you want to make a hole on the larger rectangle by adding a “transparent” on top of it?

Your best bet is to create 4 small rectangles (top,left,right,bottom) to create your border around the “central/inner” rectangle.

No, I don’t wont to make holes :) But my inner rect is partly transparent and its color is blending with outer(border rect). I don’t want any blending here.
It would be exactly what I need if there were bitwise operations on images\rectangles, but I found none.
fcrochik, your solution is obviously reasonable but it is rather the workaround. If there is no other way then I’ll use it, but maybe there is?

ixSci:

If your inner rectangle is transparent it has to blend to something. If you want to blend to the background (not the outer rectangle) than you actually “want” a hole on the outer rectangle so you can “see trough”.

I don’t think there is another way.

Ok, you understood me right.
>> I don’t think there is another way.
I’m afraid you are right but maybe Trolls will say anything about this. Because absence of bitwise operations substantially reduce capabilities for working with figures and images.

Hi,

I can confirm there is no built-in way to accomplish this — you’ll need to write your own item in QML (as suggested above; you might also want to experiment with BorderImage) or C++.

Thank you both for answers.
mbrasser, are there any plans for adding bitwise operations into QML?

With the QML scene graph project, the focus is shifting to GL shaders for graphical manipulation of items — would something like that be helpful to you in this case?

I’d like to see something like Rectangle{ overlapMode: intersect\unite\exclude etc.} but maybe I’m missing something. It happens very often when studying new technology but continue to keep in mind an older one.
Now I’m going to use a four-part border and when I have more thorough knowledge in QML perhaps I’ll offer some suggestions
