What error?

There are three layouts in total. I want the rightmost one to fill the remaining space, so I set 0,0,1. However, at this time, the leftmost layout stretches and becomes wider. The horizontal sizePolicy of all controls is set to preferred.

Because it can take its preferred size... the left layout has other widgets inside, so it respects the size of its content.
Also 0 means default/ignored stretch... if you want 33%, 33% 33% for all three layouts, set the stretch to 1, 1, 1,
While e.g. 2, 1, 1 means 1/2, 1/4, 1/4 of the available space.

If you want the right layout to only fill what's remaining, try 1, 1, 0

I want the leftmost and middle layouts to keep the minimum size, and the rightmost to fill all the remaining space. Now I changed it to (1, 4, 10), the display effect is fine, but I think the effect of (0,0,1) is weird.
