How to align a GroupBox at the top of a VerticalLayout

Hi,

I am currently working on a PyQt5 application with Python 3.9.0.

I am trying to align a GroupBox to the top of a VerticalLayout in a HorizontalLayout.
The HorizontalLayout contains a VerticalLayout (left side, Title 2 and Title 3) and a GroupBox (right side, Title 1).
The VerticalLayout contains 2 GroupBoxes (Title 2 and Title 3).
I decided to go with a VerticalLayout in a HorizontalLayout and not a GridLayout since the Title 3 GroupBox can be disabled.
This makes it so the Title 2 GroupBox will fill in the space when the Title 3 GroupBox is hidden.

As you can see in the image, the Title 2 GroupBox isn't aligned properly with the Title 1 GroupBox.
I would like them to be at the same height, so when the Title 3 GroupBox is hidden, the Title 2 and Title 1 GroupBoxes would be the same exact size.

I tried setting the contentMargins to 0 on all the components mentioned.
HorizontalLayout.setContentsMargins(0, 0, 0, 0)
VerticalLayout.setContentsMargins(0, 0, 0, 0)
Title2GroupBox.setContentsMargins(0, 0, 0, 0)
Title3GroupBox.setContentsMargins(0, 0, 0, 0)

Nothing seems to change at all. I also tried playing with the spacing but would like to keep the spacing between Title 2 GroupBox and Title 3 GroupBox as it is currently.
In my testing, the spacing didn't affect what I am trying to edit at all. Nothing seemed to affect the space I am trying to remove.

Thanks for the help!

Here is a code snippet to help visualize what I did.

        self.horizontalLayout = QHBoxLayout()
        self.horizontalLayout.setObjectName(u"horizontalLayout")
        self.horizontalLayout.setContentsMargins(0, 0, 0, 0)

        self.verticalLayout = QVBoxLayout()
        self.verticalLayout.setObjectName(u"verticalLayout")
        self.verticalLayout.setContentsMargins(0, 0, 0, 0)

        self.horizontalLayout.addLayout(self.verticalLayout)

        self.verticalLayout.addWidget(self.groupBox_Title2)

        self.verticalLayout.addWidget(self.groupBox_Title3)

        self.horizontalLayout.addWidget(self.groupBox_Title1)

Hi,

What about putting groupBox_Title1 in its own vertical layout ?

Hi SGaist,

Thanks for the suggestion, this seems to work just fine.
