Using variables in qt StyleSheets

Question

Is there any possibility of giving variable name to hex/rgb numbers in .qss file . For eh

myColor = #FFCC08
QPushButton { background-color: myColor;}

So that i can define the variable at the top of the stylesheet and use the variable name whereever required instead of using the hex code. Also if i need to change the color then i have to change in one place and it will be reflected throught the file.

I also searched for Saas but don't know how it can be used in qt.

Thanks :)

You could build your own tiny Sass quite easily:

1.Create a text file with definitions of variables. Use simple format like this:

@myColor  = #FFDDEE
@myColor2 = #112233 
@myWidth  = 20px

2.In qss file use variable names:

QPushButton { 
    background-color: @myColor; 
    min-width: @myWidth;
}

3.Open both files and for each variable in definition file change its occurrence in qss file with the value (string) from the definition file. It is a simple string replacement.

4.Apply the preprocessed qss in the app.

This is the simplest solution. You can change both definition file and qss file outside the app and apply it without recompilation of code.
