Introduction

qstylizer is a python package designed to help with the construction of PyQt/PySide stylesheets.

.. code-block:: python

import PyQt5.QtWidgets

import qstylizer.style

css = qstylizer.style.StyleSheet()
css.setValues(
    backgroundColor="green",
    color="#F0F0F0",
    marginLeft="2px"
)
css.QToolButton.setValues(
    border="1px transparent lightblue",
    borderRadius="3px",
    margin="1px",
    padding="3px"
)
css.QToolButton.menuButton.pressed.setValues(
    border="1px solid #333333",
    padding="5px",
    backgroundColor="#333333"
)
# The following is also valid and is equivalent to the statement above.
css["QToolButton::menu-button:pressed"].setValues(**{
    "border": "1px solid #333333",
    "padding": "5px",
    "background-color": "#333333",
})

css.QCheckBox.disabled.backgroundColor.setValue("#797979")

widget = PyQt5.QtWidgets.QWidget()
widget.setStyleSheet(css.toString())

The stylesheet generated above looks like this when passed to setStyleSheet()::

* {
    color: #F0F0F0;
    margin-left: 2px;
    background-color: green;
}
QToolButton {
    border-radius: 3px;
    padding: 3px;
    border: 1px transparent lightblue;
    margin: 1px;
}
QToolButton::menu-button:pressed {
    padding: 5px;
    border: 1px solid #333333;
    background-color: #333333;
}
QCheckBox:disabled {
    background-color: #797979;
}

The true power comes from parsing an existing stylesheet and tweaking individual property values.

.. code-block:: python

import qstylizer.parser

css = qstylizer.parser.parse(
    """
    QToolButton::menu-button:pressed {
        padding: 5px;
        border: 1px solid #333333;
        background-color: #333333;
    }
    QCheckBox:disabled {
        background-color: #797979;
    }
    """
)
css.QToolButton.menuButton.pressed.padding.setValue("10px")
css.QCheckBox.disabled.backgroundColor.setValue("#222222")

print(css.toString())

Output::

QToolButton::menu-button:pressed {
    padding: 10px;
    border: 1px solid #333333;
    background-color: #333333;
}
QCheckBox:disabled {
    background-color: #222222;
}
