Fill shape like paint bucket tool

[AlvaroS]

Hello everyone:

First of all thanks a lot for readint this post and being able to help.

I have a scene with four lines which represent a square.

I would like to fill the square in blue for example when I click inside the square with the mouse (like the paint tool "bucket").

how can I do that?

thanks a lot.

Hi,

One possibility would be to add a QGraphicsRectItem of the color you want in the desired quadrant.

Another possibility would be to have a custom paint event that handles the four quadrants delimited by your lines.

But first, what is the purpose of that scene ?

@SGaist Hello! thanks for replying!!

In my scene I load somw lines which represent some squares or rectangles...
So with a bucket tool I would like to fill these squares and rectangles just clicking inside them.

Could you put a little example of code to help me please?

thanks a lot
