I have created a test main window in Designer and place a bunch of UI elements in it. In struggling to get it working I find that the documentation states that you should not place a layout on the main window but place them on a widget that is defined as the central widget. I am not using a layout in this particular but in general is it best practice to create a main window with no UI on it (other than menu's, etc) and to place them all on a central widget?
As per the documentation for dialogs, I have created my main window in Designer and then subclassed it to add functionality to it. Are there any differences in doing this for main windows vs. dialogs?
Thanks.
