Detailed Description

The QProxyStyle class is a convenience class that simplifies dynamically overriding QStyle elements.

Since
4.6

\inmodule QtWidgets

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:

Warning: The \l {QCommonStyle} {common styles} provided by Qt will respect this hint, because they call QStyle::proxy(), but there is no guarantee that QStyle::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 QWidget::style(). You have to create a separate custom style for the widget similar to:

Constructor & Destructor Documentation

◆ QProxyStyle() [1/2]

QProxyStyle::QProxyStyle ( QStyle *  style = nullptr)

Constructs a QProxyStyle object for overriding behavior in the specified style, or in the default native \l{QApplication::style()} {style} if style is not specified.

Ownership of style is transferred to QProxyStyle.

Definition at line 122 of file qproxystyle.cpp.

◆ QProxyStyle() [2/2]

QProxyStyle::QProxyStyle ( const QString &  key)

Constructs a QProxyStyle object for overriding behavior in the base style specified by style key, or in the current \l{QApplication::style()}{application style} if the specified style key is unrecognized.
