设置样式 ¶

可以设置整个应用程序的样式使用 setStyle() function. It can also be specified by the user of the application, using the -style 命令行选项：

python myapplication.py -style windows
												

If no style is specified, Qt will choose the most appropriate style for the user’s platform or desktop environment.

还可以为个别小部件设置样式使用 setStyle() 函数。

开发感知样式的自定义 Widget ¶

If you are developing custom widgets and want them to look good on all platforms, you can use QStyle functions to perform parts of the widget drawing, such as drawItemText() , drawItemPixmap() , drawPrimitive() , drawControl() ，和 drawComplexControl() .

Most QStyle draw functions take four arguments:

• an enum value specifying which graphical element to draw

• a QStyleOption specifying how and where to render that element

• a QPainter 用于绘制元素

• a QWidget on which the drawing is performed (optional)

例如，若希望在 Widget 中绘制聚焦矩形，可以编写：

def paintEvent(self, event):
    painter = QPainter(self)
    option = QStyleOptionFocusRect()
    option.initFrom(self)
    option.backgroundColor = palette().color(QPalette.Background)
    style().drawPrimitive(QStyle.PE_FrameFocusRect, option, painter, self)
												

QStyle gets all the information it needs to render the graphical element from QStyleOption . The widget is passed as the last argument in case the style needs it to perform special effects (such as animated default buttons on macOS), but it isn’t mandatory. In fact, you can use QStyle to draw on any paint device, not just widgets, by setting the QPainter 正确。

QStyleOption has various subclasses for the various types of graphical elements that can be drawn. For example, PE_FrameFocusRect expects a QStyleOptionFocusRect 自变量。

To ensure that drawing operations are as fast as possible, QStyleOption and its subclasses have public data members. See the QStyleOption class documentation for details on how to use it.

为方便起见，Qt 提供 QStylePainter class, which combines a QStyle ， QPainter ，和 QWidget 。这使之可能编写

painter = QStylePainter(self)
...
painter.drawPrimitive(QStyle.PE_FrameFocusRect, option)
												

而不是

painter = QPainter(self)
...
style().drawPrimitive(QStyle.PE_FrameFocusRect, option, painter, self)
												

创建自定义样式 ¶

You can create a custom look and feel for your application by creating a custom style. There are two approaches to creating a custom style. In the static approach, you either choose an existing QStyle class, subclass it, and reimplement virtual functions to provide the custom behavior, or you create an entire QStyle class from scratch. In the dynamic approach, you modify the behavior of your system style at runtime. The static approach is described below. The dynamic approach is described in QProxyStyle .

The first step in the static approach is to pick one of the styles provided by Qt from which you will build your custom style. Your choice of QStyle class will depend on which style resembles your desired style the most. The most general class that you can use as a base is QCommonStyle (not QStyle ). This is because Qt requires its styles to be QCommonStyle s.

Depending on which parts of the base style you want to change, you must reimplement the functions that are used to draw those parts of the interface. To illustrate this, we will modify the look of the spin box arrows drawn by QWindowsStyle. The arrows are primitive elements that are drawn by the drawPrimitive() function, so we need to reimplement that function. We need the following class declaration:

class CustomStyle(QProxyStyle):
    ...
    def drawPrimitive(PrimitiveElement element, const QStyleOption *option,
                      QPainter *painter, const QWidget *widget) const;
        # element : PrimitiveElement
        # option  : QStyleOption
        # painter : QPainter
        # widget  : QWidget
        ...
												

要绘制它的向上 向下箭头， QSpinBox 使用 PE_IndicatorSpinUp and PE_IndicatorSpinDown primitive elements. Here’s how to reimplement the drawPrimitive() function to draw them differently:

void CustomStyle::drawPrimitive(PrimitiveElement element, const QStyleOption *option,
                                QPainter *painter, const QWidget *widget) const
{
    if (element == PE_IndicatorSpinUp || element == PE_IndicatorSpinDown) {
        QPolygon points(3);
        int x = option->rect.x();
        int y = option->rect.y();
        int w = option->rect.width() / 2;
        int h = option->rect.height() / 2;
        x += (option->rect.width() - w) / 2;
        y += (option->rect.height() - h) / 2;
        if (element == PE_IndicatorSpinUp) {
            points[0] = QPoint(x, y + h);
            points[1] = QPoint(x + w, y + h);
            points[2] = QPoint(x + w / 2, y);
        } else { // PE_SpinBoxDown
            points[0] = QPoint(x, y);
            points[1] = QPoint(x + w, y);
            points[2] = QPoint(x + w / 2, y + h);
        }
        if (option->state & State_Enabled) {
            painter->setPen(option->palette.mid().color());
            painter->setBrush(option->palette.buttonText());
        } else {
            painter->setPen(option->palette.buttonText().color());
            painter->setBrush(option->palette.mid());
        }
        painter->drawPolygon(points);
    } else {
    QProxyStyle::drawPrimitive(element, option, painter, widget);
    }
}
												

Notice that we don’t use the widget argument, except to pass it on to the QWindowStyle::drawPrimitive() function. As mentioned earlier, the information about what is to be drawn and how it should be drawn is specified by a QStyleOption object, so there is no need to ask the widget.

若需要使用 widget argument to obtain additional information, be careful to ensure that it isn’t 0 and that it is of the correct type before using it. For example:

const QSpinBox *spinBox = qobject_cast<const QSpinBox *>(widget);
if (spinBox) {
...
}
												

When implementing a custom style, you cannot assume that the widget is a QSpinBox just because the enum value is called PE_IndicatorSpinUp or PE_IndicatorSpinDown .

The documentation for the 样式 example covers this topic in more detail.

警告

Qt style sheets are currently not supported for custom QStyle subclasses. We plan to address this in some future release.

使用自定义样式 ¶

There are several ways of using a custom style in a Qt application. The simplest way is to pass the custom style to the setStyle() static function before creating the QApplication 对象：

#include <QtWidgets>
#include "customstyle.h"
int main(int argc, char *argv[])
{
    QApplication::setStyle(new CustomStyle);
    QApplication app(argc, argv);
    QSpinBox spinBox;
    spinBox.show();
    return app.exec();
}
												

可以调用 setStyle() at any time, but by calling it before the constructor, you ensure that the user’s preference, set using the -style command-line option, is respected.

You may want to make your custom style available for use in other applications, which may not be yours and hence not available for you to recompile. The Qt Plugin system makes it possible to create styles as plugins. Styles created as plugins are loaded as shared objects at runtime by Qt itself. Please refer to the Qt Plugin documentation for more information on how to go about creating a style plugin.

Compile your plugin and put it into Qt’s plugins/styles directory. We now have a pluggable style that Qt can load automatically. To use your new style with existing applications, simply start the application with the following argument:

python myapplication.py -style custom
												

The application will use the look and feel from the custom style you implemented.

从右到左桌面 ¶

Languages written from right to left (such as Arabic and Hebrew) usually also mirror the whole layout of widgets, and require the light to come from the screen’s top-right corner instead of top-left.

If you create a custom style, you should take special care when drawing asymmetric elements to make sure that they also look correct in a mirrored layout. An easy way to test your styles is to run applications with the -reverse command-line option or to call setLayoutDirection() 在您的 main() 函数。

Here are some things to keep in mind when making a style work well in a right-to-left environment:

• subControlRect() and subElementRect() return rectangles in screen coordinates

• QStyleOption::direction indicates in which direction the item should be drawn in

• If a style is not right-to-left aware it will display items as if it were left-to-right

• visualRect() , visualPos() ，和 visualAlignment() are helpful functions that will translate from logical to screen representations.

• alignedRect() will return a logical rect aligned for the current direction

在项视图中的样式 ¶

The painting of items in views is performed by a delegate. Qt’s default delegate, QStyledItemDelegate , is also used for calculating bounding rectangles of items, and their sub-elements for the various kind of item data roles QStyledItemDelegate supports. See the QStyledItemDelegate class description to find out which datatypes and roles are supported. You can read more about item data roles in 模型/视图编程 .

当 QStyledItemDelegate paints its items, it draws CE_ItemViewItem , and calculates their size with CT_ItemViewItem . Note also that it uses SE_ItemViewItemText to set the size of editors. When implementing a style to customize drawing of item views, you need to check the implementation of QCommonStyle (and any other subclasses from which your style inherits). This way, you find out which and how other style elements are painted, and you can then reimplement the painting of elements that should be drawn differently.

We include a small example where we customize the drawing of item backgrounds.

switch (element) {
    case (PE_PanelItemViewItem): {
        painter->save();
        QPoint topLeft = option->rect.topLeft();
        QPoint bottomRight = option->rect.topRight();
        QLinearGradient backgroundGradient(topLeft, bottomRight);
        backgroundGradient.setColorAt(0.0, QColor(Qt::yellow).lighter(190));
        backgroundGradient.setColorAt(1.0, Qt::white);
        painter->fillRect(option->rect, QBrush(backgroundGradient));
        painter->restore();
    break;
    }
    default:
        QProxyStyle::drawPrimitive(element, option, painter, widget);
}
												

The primitive element PE_PanelItemViewItem is responsible for painting the background of items, and is called from QCommonStyle ‘s implementation of CE_ItemViewItem .

To add support for drawing of new datatypes and item data roles, it is necessary to create a custom delegate. But if you only need to support the datatypes implemented by the default delegate, a custom style does not need an accompanying delegate. The QStyledItemDelegate class description gives more information on custom delegates.

The drawing of item view headers is also done by the style, giving control over size of header items and row and column sizes.

PySide2.QtWidgets.QStyle. polish ( palette ) ¶

参数

PySide2.QtWidgets.QStyle. polish ( widget ) ¶

参数

widget – QWidget

初始化外观为给定 widget .

This function is called for every widget at some point after it has been fully created but just before it is shown for the very first time.

Note that the default implementation does nothing. Reasonable actions in this function might be to call the QWidget::setBackgroundMode() function for the widget. Do not use the function to set, for example, the geometry. Reimplementing this function provides a back-door through which the appearance of a widget can be changed, but with Qt’s style engine it is rarely necessary to implement this function; reimplement drawItemPixmap() , drawItemText() , drawPrimitive() , etc. instead.

inherits() function may provide enough information to allow class-specific customizations. But because new QStyle subclasses are expected to work reasonably with all current and future widgets, limited use of hard-coded customization is recommended.
