Jimh: Yes indeed. That is true, but you cannot see those styles while editing in Designer. Hence, the feature request.

While you can’t specifically include files, it should be noted that when you add widgets to widgets the styles are inherited. So if you apply a master global style to the main app widget, it will style mostly everything in the app that is parented, and you can apply the same master global style to unparented objects.

Dave,

Thanks for this, I was banging my head against a wall, wondering why app.setStyleSheet(“:/path/to/mysheet.qss”) wasn’t working. But at least you can do:

./my_qt_app -stylesheet path/to/mysheet.qss

Alberto, yes this is possible. If you create a style like this in Designer:

QPushButton {
…
}

Then, even dynamically created buttons (i.e., buttons created with C++ code) should also use the style.

Alternatively, you can write your stylesheet code in C++ using the setStyleSheet() method on any QWidget.

Hi! My name is Alberto. I’ve seen that you use the QtDesign to add style sheet. I’ve been surfed trying to get a way of doing style sheet by code. I mean… my problem is that I’m trying to do dynamics buttons(they are created when the program is running), but I would like to change their styles… changing colors, adding borders, etc.

Is it possible to do it without using the QtDesign?
Where should I add the style sheet ?

Thanks in advnce!

Tommy,

You can use @import in your stylesheet code just like #include in your C++ code like this:

@import(:/style.css)

Assuming you applied that patch and rebuilt Qt.

You may need quotes. Can’t remember right now. But seriously, this is not standard right now and rebuilding Qt just for this feature is a big job and I don’t recommend it unless you think you really need it.

Thanks for your kindly quick response!!
It really helps a lot.

If it’s not bothering…can you tell me that:
How to include the external qss file in different forms, and where should I
put “@import” at?

Many thanks again!

Oh, I see. That patch just makes it so you can include external stylesheets files using @import in your style sheets in Designer. That way, you can have a single style sheet for all your forms, and still have a nice graphical environment in Designer.

Oh, I got it, just insert those code into that .cpp file!
Thanks!!

But, still do not know how to use it..
