In Qt, we can drag a layout widget directly from the widget bar on the left to the GUI window, and then drag the specific widget into the layout widget, so that the widget will automatically layout accordingly.

Vertical layout

Drag "Vertical Layout" from the "Layouts" bar on the left panel to the GUI window, set the layout size, and then drag 3 "Push Button" in the "Buttons" bar to the set size "Vertical Layout":

Horizontal layout

Drag "Horizontal Layout" from the "Layouts" bar on the left panel to the GUI window, set the layout size, and then drag 3 "Push Button" in the "Buttons" bar to the set size "Horizontal Layout":

Another way of horizontal layout and vertical layout

Above we use to set up a layout widget, and then put the widget into the layout widget layout. In addition, we can first place the widget in the GUI window, frame the parts that need to be laid out, and then use the horizontal layout and Vertical layout buttons in the toolbar to manage the layout of the widget:

Grid layout

Like vertical and horizontal layouts, grid layouts can use the above two methods to manage the layout of widgets:

Nested layout

In addition to laying out the subassembly, we can also nest the layout in the grid:

Container layout

In addition to using layout controls, we can also use containers for rough layout, as demonstrated by the groupBox container:

Horizontal Spacer: vertical interval

Vertical Spacer: horizontal interval.

The spacer part is in the "Spacer" column of the left widget, so let's demonstrate:

For example: we have a user name label and a user name input box, set the user name label and user name input box to "partner", set the user name label text to "user name (& 2)", indicating that the shortcut key for the user name label is Alt+2, if we press the shortcut key Alt+2, then the input character of the cursor will be moved to the user name input box.

In qt designers, the "partner" function, in the Edit partner button on the toolbar:
