    While it's nice to see the result you have, not knowing how to reproduce it makes it difficult to reproduce and understand.

      Reproduction steps:

      1. Get a widget
      2. Put a VBoxLayout on it
      3. get 2 sub widgets
      4. set layout alignment to left, top for both
      5. see the second widget not aligning to the left

        So um, could you reproduce it? Or do you need more information?

          @diniamo

          see the second widget not aligning to the left

          following the steps what you said, both widgets are aligned to left,

          Maybe I din't understand the question or Is this the problem?

            I'm sorry, I meant to say QHBoxLayout not QVBoxLayout.

              2. get 2 sub widgets
              3. right click on the widget and select layout->layout horizontally
              you can add a spacer to right in the layout and both widgets will be squeezed to the left.

                  Nop doesn't work, now it just won't let me align the first element at all.

                    That's why a minimal compilable example is useful: people work together on the same issue in the same conditions.

                      @diniamo because it has a layout already. You are talking about something in the middle of a layout.
                      write down all steps you have done from the beginning.

                        Here, a minimal compilable example. As you can see Button2 won't move strictly to the left, next to Button1.

                            Hello,
                            Can you draw on paint or any other software and post here instead of linking to other platforms
                            That will help you get your solution faster~

                              Sorry about that, I fixed it.

                              But I also made a little drawing, if it's more understandable that way:

                                @diniamo

                                Hi
                                Super with both code and picture.

                                However, its working as expected.

                                The box layout is a bit special how it operates.
                                When you put in 2 buttons. the area allocated to the layout is split into 2 parts of the same size.
                                When you then ask a button to align left, it aligns left in the half area where it belongs.

                                So it does align to the left as you can see on your picture.
                                The right button is aligned to the left of its right part of the total area.

                                You can press them to the left by using a Spacer

                                  OK, thank you, that makes sense, and what if I want to fill out the remeaning space with a widget, let's say a QFrame?

                                    Hi
                                    Then you just insert the QFrame last. and area will then be divided in 3 of same size.
                                    You can use columnStrech to alter how the space is shared.

                                    alt text

                                    Here we say we want QFrame to have more than the buttons.

                                      I now understand how these work a lot more.
