qssimport

qssimport allows you to use multiple qt stylesheet files for a single project by merging those stylesheets into a main qss file. Simply create a base .qss file that defines 1 or more @import statements that point to other stylesheets.

Installation

python3 setup.py install

Usage

• The base_dir is the path to the stylesheets
• The import_def file is assumed to be stored in the stylesheets directory
  • import_def is file where all of the @imports need to be defined
• The main_stylesheet is an optional argument that defines the name of the compiled stylesheet. if a name is not provided, the program defaults to mainStyle.qss

 from qssimport import stylesheet
 
 widget = QWidget()
 ss = stylesheet.Stylesheet(base_dir='/path/to/stylesheets/',
                            import_def_file='imports.qss',
                            main_stylesheet='myStyle.qss')
 
 ss.style_widget(widget) #apply a stylesheet to widget

Example

Given the following:

import.qss

@import "lineEdit.qss";
@import "widget.qss";

lineEdit.qss

QLineEdit{color:#FFF;}
QLineEdit{background:#A06;}

widget.qss

QWidget{background:#434343;}
QWidget#MyWidget{background:#909090;}

The file you specified as main_stylesheet will contain all of the lines from lineEdit.qss and widget.qss

myStyle.qss

QLineEdit{color:#FFF;}
QLineEdit{background:#A06;}
QWidget{background:#434343;}
QWidget#MyWidget{background:#909090;}
