"""Example of qdarkstyle use for Python and Qt applications.
|
|
|
|
This module a main window with every item that could be created with
|
|
Qt Design (common ones) in the basic states (enabled/disabled), and
|
|
(checked/unchecked) for those who has this attribute.
|
|
|
|
Requirements:
|
|
|
|
- Python 2 or Python 3
|
|
- QtPy
|
|
- PyQt5 or PyQt4 or PySide2 or PySide
|
|
- PyQtGraph or Qt.Py (if choosen)
|
|
|
|
To run this example using PyQt5, simple do
|
|
|
|
.. code-block:: python
|
|
|
|
python example.py
|
|
|
|
or
|
|
|
|
.. code-block:: python
|
|
|
|
python example.py --qt_from=pyqt5
|
|
|
|
Other options for qt_from are: pyqt5, pyside2, pyqt, pyside, qtpy, pyqtgraph, and qt.py.
|
|
Also, you can run the example without dark theme (no_dark), to check for problems.
|
|
|
|
.. code-block:: python
|
|
|
|
python example.py --qt_from=pyqt5 --no_dark
|
|
|
|
Note:
|
|
qdarkstyle does not have to be installed to run the example.
