Consider a dialog window:
I want button 1 to be centered horizontally, and button 2 to be in the right corner. How to achieve this?
You can put a horizontal layout that contains a horizontal spacer, pushbutton and another horizontal layout. This second horizontal layout contains a horizontal spacer and a pushbutton.
Something like this:

I have a QWidget with following items aranged in a vertical layout:
- QWidget
- QVBoxLayout
- QPushButton
- QPushButton
- QPushButton
- QListView
- QComboBox
now, I would like to arrange the QComboBox in a horizontal alignment to one of the buttons. I gave the booton a maximumSize of 36 x 16777215 and it sits at the top left of the widget. How Do I get the combo box to align on the right side of it? Here's a screen shot of what I currently have:
Embed your combobox into an horizontallayout and add spacer https://doc.qt.io/archives/2.3/designer/chap4_2.html
You can add a QWidget (or a QFrame) at the top of your vertical layout, then you give this widget (or frame) an horizontal layout and you put your button and your combox box inside this widget with the horizontal layout.
What I'm trying to accomplish is a very simple and straight forward need, or I thought, but for the life of me, I can't seem to find a way to do it.
In my qt application I want to be able to make a widget or a layout fill the entire space of the parent widget.
For example, let's say I want to have a label with a fixed height and beneath it a stacked widget which occupies the rest of the height of the window.
Here's what I do in the qt-creator designer:
drag a label to the form
drag a stacked widget to the form
select both of them and then right click > lay out > lay out vertically
select the verticalLayout object and in the layoutStretch property have 0,1
Now, how do I make the verticalLayout occupy all of the width/height of the centralWidget?
Nothing seems to work for me.
Thanks.
You've merely put two widgets in a layout, but you also need a layout on their parent widget - on the form. Here's what you should do instead:
Drag any number of widgets to the parent widget (the form). Arrange them roughly the way you want them to be once laid out.
Right click on the form. Select "Lay out >" submenu.
Choose the desired layout from the menu: horizontal, vertical, grid, etc.
I'm having trouble adding a QScrollArea to a layout within a QDialog widget. When I add the scroll area to the layout, it appears where I want it with the widget I've assigned to it and it scrolls just fine. However, I am also left with a blank scroll area stuck to the top left of my dialog, as if I hadn't added the scroll area to the layout at all!
Why is this happening?
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...
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].
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.
That grid layout will make placing other widgets quite hard. Try this instead:
Add (from left to right) horizontal spacer and the two buttons.
Multiselect them all.
Select "Lay Out Horizontally" (Ctrl-H) from the Qt Designer's (or Qt Creator's) top toolbar (not from the widget box in the left!).
Add vertical spacer on top of the previous widgets.
Select the main window by clicking it (none of the added widgets are now selected).
Select "Lay Out Vertically" (Ctrl-L) from the top toolbar.
Done.
It seems that you're doing it correctly. Just forgot to apply a layout to your central widget, right? The Grid layout should be arranged in your central widget. The more convenient way is to remove grid layout widget and lay out the central widget in a grid ;-)
Is it possible to set widget in center of dialog or windows in QDesigner, say I have a widget contain 3 line edits and labels and I want to set this widget in center of window.
In latest Qt Designer, right-click a widget in the Object Inspector and choose your preference under Layout Alignment.
It should be quite simple:
Insert horizontal spacer
Set Horizontal layout
Insert Vertical layout
Insert another horizontal spacer
Add Vertical spacer to Horizontal spacer (drag to widget tree)
Add your widgets .... labels, textedits
Add another vertical sapcer to Horizontal space
Works in my QtCreator, should also in Your Designer :)
Good luck.
Add a layout to your windows and add the widgets in the layout. Then you can set the position policy in the properties panel of the layout.
