Qt学习笔记之样式表

一、概述

Qt的样式表是从Qt4.2开始引入的描述窗口部件外观的机制，类似于HTML的层叠样式表（Cascading Style Sheets，CSS）。样式表在Qt的风格之上起作用（如果使用了样式表，QWidget::style()返回的QStyle为“style sheet”），提供了比QPalette更为灵活、更强大的机制。样式表使用文本描述，可以在应用程序级别和widget级别设置样式表。如果在不同的级别都设置了样式表，则Qt继承所有有效的样式，这就是层叠（cascading）。

1.1 样式表语法

样式表的语法和HTML CSS基本是一致的。Qt的样式表对大小写不敏感，但对类名、对象名和属性名大小写敏感。如下的示例设置了所有QTextEdit对象背景是黄色的，所有QPushBox对象文本为绿色：

1.1.1 样式规则

样式表包含一系列的规则，一个样式规则由选择符和定义组成。选择符（selector）确定哪些窗口部件受规则影响，定义说明了在窗口部件上应用哪些属性。

在这条规则里，QRadioButton是选择符，{color:red}是定义。这条规则说明了QRadioButton和它的子类应该使用红色作为前景色。几个选择符可以使用一个定义，使用逗号分隔选择符，例如：

定义由一个或多个属性和值对组成，中间用分号隔开，例如：

1.1.2.选择符类型

Qt支持CSS2中所有的选择符，表14-14给出了常用的选择符。

1.1.3.子控件

对于复杂控件，可以访问它的子控件，如QComboBox上的下拉按钮，QSpinBox上的向上和向下箭头，例如：[插图]上面的代码使用了自定义的下拉按钮图像，::是CSS3中的伪元素。 

上面的代码使用了自定义的下拉按钮图像，::是CSS3中的伪元素。

1.1.4.伪状态

选择符可以包含伪装态来表示widget的状态，伪状态在选择符之后，以冒号分隔，下面定义了当鼠标在QPushButton上悬停时的规则：

1.1.5.冲突解决

当不同的规则应用到相同的属性时，样式表就产生了冲突。在这种情况下，特定的规则比通用的规则优先，伪状态比没有伪状态的优先，如果级别相同，则最后一个规则优先。冲突解决按照CSS2规范进行。

1.1.6.层叠样式表

可以在QApplication级别设置，也可以在父widget、子widget级别设置。实际应用样式时，则合并这几个级别的样式。当有冲突时，widget自身的样式优先使用，接下来是父widget、祖先widget，依此类推。

1.1.7.盒子模型

窗口部件和子窗口部件支持背景（background）、边框（border）、边距（margin）、填衬（padding），图1显示了样式表的盒子模型。

可以看出边距、边框、填衬和内容之间的关系。默认情况下，margin、border-width、padding属性为0，也就是说这几个矩形框是重合的。如果指定了窗口部件的背景，默认情况下，背景只对边框内部区域起作用，但可以通过改变background-clip属性来指定不同的区域填充。

二 、StyleSheet的使用

StyleSheet文件的默认后缀名为qss，可以通过命令行参数 -stylesheet filename.qss 来设置样式表，也可以通过QApplication::setStyleSheet 或 QWidget::setStyleSheet来设置应用程序或特定控件要使用的样式表。

::setStyleSheet函数的参数是字符串（不是qss文件的名字，而是样式表的内容），所以直接使用的话，不方便一次设置大量的规则，但是可以使用资源文件将qss样式表嵌入到程序中，然后通过QApplication::setStyleSheet来使用，例如：

 //! 加载样式表
    QFile file(":/qss/psblack.css");
    if (file.open(QFile::ReadOnly)) {
        QString qss = QLatin1String(file.readAll());
        qApp->setStyleSheet(qss);
        file.close();
    } 

一条样式表规则由选择器 (Selector)和属性定义(declaration)组成。

QComboBox#myComboBox::down-arrow:pressed {  
    position: relative;  
    top: 1px; left: 1px;  
}  

这部分是选择器，用于指定样式表规则的应用对象，细分开来：

• QComboBox#myComboBox 这一部分叫类型选择器(Type Selector)，QComboBox指定了对象类名，#name指定对象的实例名（非必须）其它的选择器语法请参考官方文档。
• down-arrow 子控件描述符(subcontrol)，和前面的字段用::隔开，这里表示组合框的下拉按键
• pressed 伪状态(Pseudo-States)描述符，和前面的字段用:隔开，这里表示压下状态

以上除了第一个字段，都不是必须，而是进一步限制规则适用范围

2.1 样式表规则的范围和优先级关系

规则冲突

多条规则制定了不同的内容，可能的情况有很多，比如

QPushButton:hover { color: white }
QPushButton { color: red }

这种情况，其实可以不算冲突，更加具体的类型描述符定义的规则拥有更高优先级，所以一个有鼠标悬停的按钮的文本颜色就是白色的，否则为红色

QPushButton:hover { color: white }
QPushButton:enabled { color: red }

这里就可能发生规则冲突，当一个使能的按钮有鼠标悬停的时候，颜色的定义是什么呢？ QStyleSheet的判断原则是，后面规则的优先级高于前面的规则，所以这种情况颜色为红色

QPushButton { color: red }
QAbstractButton { color: gray }

这个相对难发现，一个基类及其子类都定义了针对文本颜色的规则，那么子类应用哪一条规则呢？你可能会认为自然是子类用自己的规则了，很可惜不是，样式表不考虑类的继承层级优先关系，所以还是后一条规则优先级高于前一条规则。如果确实要单独设定子类的规则，需要交换规则的顺序。

样式表层叠 Cascading

因为样式表可以应用在QApplication上，也可以单独应用在控件上，所以最终应用到一个具体控件的样式表，是通过叠加合并所有的父控件乃至应用程序的样式表设定来得到的。这种情况下，也有可能发生规则冲突, 例如：

qApp->setStyleSheet("QPushButton { color: white }");  
myPushButton->setStyleSheet("* { color: blue }");  

这种情况下，控件自身的样式表的优先级高于父控件或应用程序的样式表

样式表继承 Inheritance

在标准的CSS样式表中，一个控件的字体和颜色属性如果没有明确设定，那么将自动继承自父控件，而在QT的样式表中，不会自动继承，例如：
qApp->setStyleSheet("QGroupBox { color: red; } ");

这种情况下，对于GroupBox中的添加的子控件，不会自动设置其颜色属性，如果要设置子控件的属性，需要明确设定：
qApp->setStyleSheet("QGroupBox, QGroupBox * { color: red; }");

注意，这里的继承和上面的层叠不一样，层叠指不同样式表设置同一个对象，继承指的则是样式表规则中选择器对控件层级关系的影响
