This stylesheet aims to be similar across all platforms, and provide a nice UI for different DPIs (as determined by the default font size, or using the screen scale factor). This is currently under work for scaling to multiple different DPIs and font sizes.
To compile the stylesheet for use with PyQt5, compile with the following command `pyrcc5 breeze.qrc -o breeze_resources.py`, and import the stylesheets. Afterwards, to load the stylesheet in Python, load the file using QFile and read the data. For example, to load BreezeDark, run:
Since [pyrcc](https://www.riverbankcomputing.com/pipermail/pyqt/2020-September/043209.html) is no longer being maintained, using local Python paths is the preferable solution. For a detailed description on how to package these resources, see this StackOverflow [answer](https://stackoverflow.com/a/20885799/4131059).
First, package your code using setuptools. Make sure `zip_safe` is off, so we can properly load the files from a search path, and include the necessary package directories to your `MANIFEST.in` file.
```python
from setuptools import setup
setup(
# Either option is valid here.
# Either use `package_data` with enumerating the values, or
# set `include_package_data=True`.
include_package_data=True,
package_data={
'breeze_theme.dark': ['dark/*'],
'breeze_theme.light': ['light/*'],
# Add any more themes here.
},
zip_safe=False,
)
```
Then, you can import the resources as follows:
```python
import importlib.resources
from Qt6 import QtWidgets, QtCore
from Qt6.QtCore import QFile, QTextStream
def main():
app = QtWidgets.QApplication(sys.argv)
# set stylesheet
# Note that the search path name must be the theme name.
It's easy to design your own themes using `configure.py`. First, add the styles you want into [theme](/theme/), then run configure with a list of styles you want to include.
Here is a sample theme, with the color descriptions annotated. Please note that although there are nearly 40 possibilities, for most applications, you should use less than 20, and ~10 different hues.
As a reference point, see the pre-generated [themes](/theme). In general, to create a good theme, modify only the highlight colors (blues, greens, purples) to a new color, such that the saturation and lightness stay the same (only the hue changes). For example, the color `rgba(51, 164, 223, 0.5)` becomes `rgba(164, 51, 223, 0.5)`.
There are some limitations of using Qt stylesheets in general, which cannot be solved by stylesheets. To get more fine-grained style control, you should subclass `QCommonStyle`:
```c++
class ApplicationStyle: public QCommonStyle
{
...
}
```
An extensive reference can be found [here](https://doc.qt.io/qt-5/style-reference.html). A reference of QStyle, and the default styles Qt provides can be found [here](https://doc.qt.io/qt-5/qstyle.html).
To configure the assets and the stylesheets, run `configure.py`. To compile the assets and stylesheets for Python, run `pyrcc5 breeze.qrc -o breeze_resources.py`.
In order to test your changes, first run the tests using the appropriate widget in `test.py` (see the options for `stylesheet`, `widget`, `font-size`, and `font-family`), and then run the tests with the complete UI in `example.py`. If the widget you fixed the style for does not exist in `example.py`, please add it.
