QT - Place Buttons on Bottom Right

Question

I am trying to place a set of buttons so that they are anchored to the bottom right of the screen. My problem is that whenever I resize the screen, the buttons are not anchored to the bottom right, but stay in its current position.

I have placed two Push Buttons inside a Horizontal Layout. I then placed this layout inside a Grid Layout, which contains a Horizontal and Vertical Spacer. I have modified the Grid Layout layoutSize property to SetMaximumSize.

What am I doing incorrectly, so that I can get my buttons to be anchored to the bottom right?

You have almost everything just right here, but you probably overlooked something that is really easy to miss when you first start using Qt Designer.

Your grid layout is sitting inside your widget with a fixed size and position. It too needs to be managed by a layout. If you take a look at the Object Inspector on the top right (that contains your hierarchy) you will probably see your top level widget with a red icon. This indicates that it contains no layout. You have two options to fix this...

1. Have your existing grid layout placed into another main layout (like a vertical layout). You would simply right click on your top level widget in the Object Inspector -> Lay Out -> [Choose a main layout type].
2. Have your grid be the main layout. To do this you would need to remove the grid layout and have your child items arranged exactly how you have them in that picture. Then follow the previous option, right clicking on the top level widget (or the blank background) and choose Lay out -> Grid. This will pop your widgets into a Grid at a best visual fit (which you can then fix if needed), and your grid will be the top level layout.
