Qt学习笔记--QSS样式表

QSS

简介

QSS称为Qt Style Sheets也就是Qt样式表，它是Qt提供的一种用来自定义控件外观的机制。QSS大量参考了CSS的内容，只不过QSS的功能比CSS要弱很多，体现在选择器要少，可以使用的QSS属性也要少很多，并且并不是所有的属性都可以用在Qt的所有控件上。

语法规则

QSS语法主要包含两类：控件和属性。控件表示受影响的控件类型和控件编号，又叫选择器。属性表示要改变的控件属性。例如QPushButton { color: red }表示控件QPushButton以及其子类的color属性为红色。

选择器

• 通配型选择器* ：匹配所有控件
• 类型选择器object：匹配指定的控件类型及其子类
• 属性选择器object[**]：例如QPushButton[flat=“false”],匹配所有flat属性为false的按钮
• 类选择器.object：匹配所有指定类型实例，但不匹配子类。
• ID选择器#ID：匹配ID对应的控件，指定控件名字。
• 后代选择器Qdialog QPushButton：所有Qdialog容器中包含的QPushButton。
• 子选择器Qdialog > QPushButton：所有Dialog下的QPushButton。

另外上面所有的这些选择器可以联合使用，并且支持一次设置多个选择器类型，用逗号隔开，这点与CSS一样，例如#frameCut,#frameInterrupt,#frameJoin 表示所有这些id使用一个规则。#mytable QPushButton 表示选择所有id为mytable的容器下面的QPushButton实例

子控件

用法

控件类型 ：：子控件类型 { 属性：属性值 }
QComboBox::drop-down { image: url(dropdown.png) }

常见子控件

• ::down-arrow combo box或spin box的下拉箭头
• ::down-button spin box的向下按钮
• ::drop-down combo box的下拉箭头
• ::indicator checkbox、radio button或可选择group box的指示器
• ::item menu、menu bar或status bar的子项目
• ::menu-indicator push button的菜单指示器
• ::title group box的标题
• ::up-arrow spin box的向上箭头
• ::up-button spin box的向上按钮

伪状态

QSS的伪状态选择器实际上与CSS中的类似，是以冒号开头的一个选择表达式。例如:hover表示当鼠标经过时候的状态。他限制了当控件在某一种状态下的时候才能应用QSS规则，伪状态只能描述一个控件的状态，或者是一个复合控件中的子控件的状态，所以该伪状态选择器只能放在选择器的最后面。

用法

控件类型 ：控件伪状态 { 属性：属性值 }
QComboBox:hover { image: url(dropdown.png) }

常见伪状态

• :checked button部件被选中
• :disabled 部件被禁用
• :enabled 部件被启用
• :focus 部件获得焦点
• :hover 鼠标位于部件上
• :indeterminate checkbox或radiobutton被部分选中
• :off 部件可以切换，且处于off状态
• :on 部件可以切换，且处于on状态
• :pressed 部件被鼠标按下
• :unchecked button部件未被选中
  实例：

QPushButton:hover{
        color: rgba(85, 170, 255,100);
        background-color: rgba(85, 230, 127,100);
}

实现方法

• 新建QT工程
• 新建style.qss文件，写入qss样式表。
• 新建qrc，添加样式表和资源文件
• 代码启用样式表

#include "widget.h"
#include 
#include 
#include 
#include 
#include 
#include 

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    //读取样式表文件
    QFile my_style(":/qss/style.qss");
    if(my_style.open(QFile::ReadOnly))
    {
        QString style_string = QLatin1String(my_style.readAll());
        //设置启用样式表
        a.setStyleSheet(style_string);
        my_style.close();
    }

    Widget w;
    w.show();

    return a.exec();
}

• 有时候背景图不能自行刷新，需要添加如下代码进行刷新：

.....
#include 
......

void Widget::paintEvent(QPaintEvent *event)
{
    Q_UNUSED(event);
    QStyleOption o;
    o.initFrom(this);
    QPainter p(this);
    style()->drawPrimitive(QStyle::PE_Widget, &o, &p, this);
    QWidget::paintEvent(event);
}

效果展示

• 按下状态
  
• 聚焦状态
  
• 初始状态
  

对应样式表

        image: url(:/background.jpg);
        background-image: ;
