Layout alignment option doesn't actually align widget in QHBoxLayout

diniamo

I have 2 widgets inside of the mentioned layout, both with top vertical, and left horizontal alignment. Now the problem is that both of them get aligned to the top vertically, but the second object doesn't get aligned horizontally whatever I set for that option.

I am using Qt 6 with C++ and forms.

Hi,

Please provide a minimal compilable example that shows the behaviour your describe.

diniamo

I hope a screenshot is enough.

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

diniamo

Reproduction steps:

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

Like this:

diniamo

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

Thank You

@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?

diniamo

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

@diniamo
1. Get a widget
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.

Thank You

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:

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?

mrjj

@diniamo
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.

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