Qt Creator WYSIWYG isn't giving a true representation
-
@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.

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

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.
Kind Regards,

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.

Weird. Shouldn't be the case, if done right.

@Pl45m4 , in fact every thing I've tried still results in the label showing everything except the first letter "S".

This is part of the form whilst editing in Qt Creator:
This is the same form when running as application on desktop:
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 thingsTry 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 itWhy 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

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.

This thread started with you saying that QtDesigner does not use system theme (which is correct observation).

@SPlatten "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." - you wrote this, right?
Also: "Qt Creator should present the forms in the way they will look when running on the host, which currently is very different"So, what I mean is: QtDesigner does not use the system theme (the one used in the OS it is running on).

ok, thank you, and why is that? Surely thats either a design fault?
No design fault - it's a design feature that your app uses the style of the OS so it looks native.

@jsulm , ok, thank you, and why is that? Surely thats either a design fault?
Is it a setting I can change?

I agree that the Qt Designer is not very good. I had a harder time learning the designer instead of writing C++ code. Especially handling layouts is quite cumbersome in the designer. Most of the time I would be much faster writing things down in C++. But our project uses ui-files.
You can have a look how things would look like in the native style by using the menu: Tools -> Form Editor -> Preview. It is not entirely WYSIWYG, but you don't have to compile and run your application first to see how it looks. It will not know about your stylesheets, though (maybe there is a way to let it know about them). Also, showing a dialog in your application might actually resize the widget (especially when it contains layouts) whereas the preview shows you the same size as the designer.
The designer was done for designers who don't know how to code. If you know how to code, I personally prefer to write things down in C++. This gives me much better control over everything and even shifting around things inside the layout is much faster. Sometimes to add something to a complex grid layout you have to break the layout first, then reposition everything in the designer so that when you reapply the grid layout it will pick up on everything correctly. That is way faster in C++ code.
I don't expect any improvements for the Qt Designer. Designers (the people) are now targeted with QML instead (and also Qt Studio and the like with the commercial licenses).
