    @jsulm, Given the age and maturity of Qt Creator I would expect this to be the default behaviour.

    @SPlatten Since I'm not a QtDesigner developer I can't comment on the reasons for that, you can ask on the Qt mailing list.

      How can I set-up Qt Creator to match what will be in the final application when running?

      Layouts apply first when you run your app. So, what you see in QtCreator's Design mode may look different from what your app / widgets really look on runtime.

      They also take effect in designer (try to resize the form with properly set layouts).

        But nevertheless the behavior / look is or feels a bit different in QtDesigner (from my experience)

          @Pl45m4 , why? When I use an WYSIWYG editor I expect the output to be exactly as I design, unless I resize it.

          What layouts do you have here and how are your sizeHints and stretches configured?

            @Pl45m4, the main layout is a QGridLayout, however the controls that I'm having a problem with are not in the layout they children of the centralWidget.

              That's why I asked (two times) what happens if you resize the form in designer, but you still did not answer...

                  @SPlatten So, this is indeed a problem with layouts (or lack of layouts) and not themes...

                    So your "Select Trainee" label is floating around? :)
                    Then you don't have to wonder why other widgets cover it.

                      @Pl45m4 , On this form there are four buttons to the left of the label, these are all of a specific size and position, when viewing in designer everything looks great and nothing is wrong.

                      When I launch the application I am not resizing or moving anything, it initial state looks very different from how it did in designer.

                      No other widgets are covering it, the font size and size of the label is different.

                        I thought the button on the left is covering your text...

                        the font size and size of the label is different.

                        Because the size of your label is not expanding with its content, because no layout will stretch your label :)
                        You could try to set a minimum size in QtDesigner that fits your content.

                          @Pl45m4 , thank you, I've dropped in a Horizontal Layout and added the top row of controls to that, the application is better, although the presentation in designer is still not the same and whilst it's perfect in designer, the application still has a label that isn't displaying all characters.

                                I believe there's still something wrong. Show your layout please (the layout / widget setup and the result you get)

                                  This is part of the form whilst editing in Qt Creator:
                                  creator.png

                                  This is the same form when running as application on desktop:
                                  IMG_0355.jpg

                                  In both cases I've screen printed and cropped the area. Why is the final presentation in the compiled application when running on the desktop so different from the view in Qt Creator?

                                  Also notice the controls used in Qt Creator are not quite the same as those when running in the application, note that the rectangles for the buttons and combo are sharp when running in the application and very slightly rounded when running in Qt Creator.

                                  I'm using Qt 4.4.1, Based on Qt 5.9.2 (MSVC 2015, 32 bit).

                                  I think it is layout issue.
                                  In QT Creator You see it
                                  But while compiling it may show some or none of things

                                  Try applying horizontal layout label and QComboBox as discussed by @Pl45m4
                                  Then I am sure It will work
                                  It may not work if the window size is small Try resizing it

                                  Why you can't expect the output from QT Creator
                                  The height and width in QT Creator just for there unless layout is applied to it?
                                  If the design in QT Creator fills the screen properly Then would you expect it fill to all screens in the same behaviour "NO"
                                  So It's specific to that size only So I guess layouts are
                                  EASY

                                  I hope it helps

                                  Let's make QT free or It will go forever

                                    I think it is layout issue.
                                    In QT Creator You see it
                                    But while compiling it may show some or none of things

                                    Try applying horizontal layout label and QComboBox as discussed by @Pl45m4
                                    Then I am sure It will work
                                    It may not work if the window size is small Try resizing it

                                    Why you can't expect the output from QT Creator
                                    The height and width in QT Creator just for there unless layout is applied to it?
                                    If the design in QT Creator fills the screen properly Then would you expect it fill to all screens in the same behaviour "NO"
                                    So It's specific to that size only So I guess layouts are
                                    EASY
                                    RESPONSIVE

                                    I hope it helps

                                    This is now resolved, I redid the main window ui, the top line buttons and widgets are now in a horizontal layout with the main window content in a grid layout. As a WYSIWYG editor Qt Creator is rubbish because the presentation of what you see is not what you get.

                                      I don't see how this should work - first you've styles which slightly modifies the items and then you can set the sizes and others by code - so what do you expect that this should work out?
                                      That's why you have to use layouts - they arrange the widgets the way you want without killing the layout when another style is used or similar.

                                        I think the mistake you were doing was that you were designing your UI manually (positions and sizes of the widgets) for a specific theme. This is a very bad idea in my opinion because your UI is going to break as soon as the theme changes.
                                        Lets assume QtDesigner would use the system theme, you are on Windows 10 and design your UI manually, everything is fine. One day Microsoft changes the theme (this will for sure happen one day) - your UI breaks, you have to adjust the UI and rebuild your app for the new Windows version. And there is one more thing to consider: if you're working on a cross platform app then your UI will only behave properly on the platform were you created it...

                                        I use QtDesigner a lot and don't see how it is rubbish as long as you use layouts. So, instead of blaming the tool use it properly.

                                          Perhaps rubbish is too harsh, but I've used various GUI tools and IDE's and generally when designing a GUI in a front end, what you end up with in your application is exactly how you left it in the designer. This isn't always the case in Qt Creator.

                                          I'm not sure what you mean by themes, I drag and drop widgets from the palette onto the form and edit properties if required, in code I didn't modify anything, however now its fixed.
