sidebar = QToolBar()
sidebar.setProperty("type", "sidebar")

Widget	Property	Property value	Default	Command for demo
QToolBar	type	toolbar, sidebar	toolbar	python -m qdarktheme.examples.sidebar
QPushButton	type	outlined, contained, text	outlined	python -m qdarktheme.examples.pushbutton
QLineEdit	state	normal, warning, error	normal	python -m qdarktheme.examples.lineedit
QFrame	type	normal, h_line, v_line	normal	python -m qdarktheme.examples.line

Support Qt Designer

This module support Qt Designer.

How to use PyQtDarktheme with Qt Designer.

1. Run the following command in the terminal to launch the app that creates the template for the designer.

   python -m qdarktheme.designer_supporter
   

2. Select a theme(dark or light) and press the Create button to create a template in any folder.
3. Copy the style sheet displayed in the text box.
4. Start Qt designer and save the ui file in the root of the template you created.
5. Paste the copied stylesheet into the top-level widget.
6. Register the resource file(.qrc) in the template to the resource browser.

⚠ Support for Qt’s resource system has been removed in PyQt6. Therefore, if you want to use Qt Designer in PyQt6, you need to delete the stylesheet in the ui file and load the stylesheet using load_stylesheet().
