Detailed Description¶

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

A QProxyStyle wraps a QStyle (usually the default system style) for the purpose of dynamically overriding painting or other specific style behavior.

The following example shows how to override the shortcut underline behavior on any platform:

from textedit import *
from PySide6.QtWidgets import QApplication
from PySide6.QtWidgets import QProxyStyle
class MyProxyStyle(QProxyStyle):

#   public
    int styleHint(StyleHint hint, QStyleOption option = None,
                  widget = None, QStyleHintReturn returnData = None) override()

        if hint == QStyle.SH_UnderlineShortcut:
            return 0
        return QProxyStyle.styleHint(hint, option, widget, returnData)


if __name__ == "__main__":

    Q_INIT_RESOURCE(textedit)
    a = QApplication(argc, argv)
    a.setStyle(MyProxyStyle())
    mw = TextEdit()
    mw.resize(700, 800)
    mw.show()
    #...

Warning: The common styles provided by Qt will respect this hint, because they call proxy() , but there is no guarantee that proxy() will be called for user defined or system controlled styles. It would not work on a Mac, for example, where menus are handled by the operating system.

When a proxy style should be set on a specific widget only, you have to make sure to not set the proxy on the global application style which is returned by style() . You have to create a separate custom style for the widget similar to:

...
proxy = MyProxyStyle(QApplication.style().name())
proxy.setParent(widget) # take ownership to avoid memleak
widget.setStyle(proxy)
...
