[Solved] Using variables in style sheets qss

pritamghanghas

I dont think stylesheets have support for that.
you can group rules together, not sure about the exact syntax

QPushButton QLabel QWidget { background-color: #DFDFE0 }

You can use a text template for the style sheet, create the actual stylesheet as a combination of the template and a theme and set it. See Grantlee for string templating. I did something similar, used just basic string replacement and it works fine.

@miroslav

Can you give some examples about how can i use this in stylesheets(.qss) file , that will be really helpful. I have gone through the "documentation":http://www.grantlee.org/apidox/for_themers.html but couldn't understand much about how to use it.

Thanks for your time.

I'd suggest looking at the book example or the unit tests in the grantlee repository. I think the books example is the most complete small example.

Thanks, Stephen!

clepto

Sam

I am trying to run the book example provided in "Grantlee repository":http://gitorious.org/grantlee.
Dont know where i am going wrong, whenever i run the project i get the following errors

@13:52:01: Running build steps for project books...
13:52:01: Configuration unchanged, skipping qmake step.

What steps should i follow to make this working.
Thanks.

I tried but still couldn't get this working.

You do not need a full-blown template library just to replace some text. If this fits your needs doing a simple QString::replace() does the trick as well.

@
QPushButton { background-color: myColor; }

QString styleSheet = ...;
styleSheet.replace("myColor", "#DFDFE0");
styleSheet.replace(...);
@

I just want to mention that this does not do what you expect it to do.

If you want to group several selectors you will have to use commas. <code>QPushButton, QLabel, QWidget { background-color: #DFDFE0 }</code>

Without commas, you are doing a descendant selection.

Thanks for the help,

For the implementation we created a parser that would parse the css file with the user defined variable and replace the variable with the actual color code.
