[Interest] QLineEdit "stretch" in QHBoxLayout using designer

[Alex Malyushytskyy]

Carl,

Keep in mind for layout to work it has to be re-sized properly one way
or another.
Currently it is not. In your case you might want to create  layout for
the widget you place your controls on.
As for now layout you created has no any connection to the dialog boundaries.

I will try to explain what you did in one dimension

Point 1,4- left and right widget boundary 2,3 boundaries of your layout,

1               2 --------------- 3          4

1 and 2 are not connected anyhow, neither 3 and 4.
So your layout is not re- sized.

To achieve what I expect you want,
click your widget and click Layout vertically.

This will create your widget layout and add layout with 2 buttons in it.
If you are going to have only 2 widgets there you can destroy existing layout ,
since all you really need is "main widget" layout ( again, click
widget/dialog click Layout vertically )


Hope this helps.

Alex
