Detailed Description

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

Since

4.6

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:

#include "textedit.h"
#include <QApplication>
#include <QProxyStyle>

class MyProxyStyle : public QProxyStyle
{
  public:
    int styleHint(StyleHint hint, const QStyleOption *option = 0,
                  const QWidget *widget = 0, QStyleHintReturn *returnData = 0) const
    {
        if (hint == QStyle::SH_UnderlineShortcut)
            return 0;
        return QProxyStyle::styleHint(hint, option, widget, returnData);
    }
};

int main(int argc, char **argv)
{
    Q_INIT_RESOURCE(textedit);

    QApplication a(argc, argv);
    a.setStyle(new MyProxyStyle);
    TextEdit mw;
    mw.resize(700, 800);
    mw.show();
    //...
}

Warning: The 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.

Constructors and Destructors

QProxyStyle()

QProxyStyle::QProxyStyle

(

QStyle *

style = 0

)

Constructs a QProxyStyle object for overriding behavior in style or in the current application style if style is 0 (default).

Normally style is 0, because you want to override behavior in the system style.

Ownership of style is transferred to QProxyStyle.

Definition at line 119 of file qproxystyle.cpp.

                                      :
    QCommonStyle(*new QProxyStylePrivate())
{
    Q_D(QProxyStyle);
    if (style) {
        style->setProxy(this);
        style->setParent(this); // Take ownership
        d->baseStyle = style;
    }
}

~QProxyStyle()

QProxyStyle::~QProxyStyle

(

Destroys the QProxyStyle object.

Functions

baseStyle()

QStyle * QProxyStyle::baseStyle

(

)

const

Returns the proxy base style object.

If no base style is set on the proxy style, QProxyStyle will create an instance of the application style instead.

protectedslot

This slot is called by layoutSpacing() to determine the spacing that should be used between control1 and control2 in a layout.

orientation specifies whether the controls are laid out side by side or stacked vertically. The option parameter can be used to pass extra information about the parent widget. The widget parameter is optional and can also be used if option is 0.

The default implementation returns -1.

standardIconImplementation

QIcon QProxyStyle::standardIconImplementation ( StandardPixmap  standardIcon, const QStyleOption *  option, const QWidget *  widget  ) const

protectedslot

Returns an icon for the given standardIcon.

Reimplement this slot to provide your own icons in a QStyle subclass. The option argument can be used to pass extra information required to find the appropriate icon. The widget argument is optional and can also be used to help find the icon.

Note

Because of binary compatibility constraints, standardIcon() introduced in Qt 4.1 is not virtual. Therefore it must dynamically detect and call this slot. This default implementation simply calls standardIcon() with the given parameters.
