设计Qt程序Ui的时候,可以像WEB端使用CSS一样,使用QSS,使页面美化跟代码层分开,利于维护。

过程如下:

    1、建立文本文件,写入样式表内容,更改文件后缀名为qss;

    2、在工程中新建资源文件*.qrc,将qss文件加入资源文件qrc中,此处注意prefix最好为"/",否则在调用qss文件时会找不到文件;

    3、通过传入路径\文件名的方式创建一个QFile对象,以readonly的方式打开,然后readAll,最后qApp->setStyleSheet就可以使qss生效。

 

 

代码如下

QString qss;



    QFile qssFile(":/qss/css.qss");

    qssFile.open(QFile::ReadOnly);

    if(qssFile.isOpen())

    {

        qss = QLatin1String(qssFile.readAll());

        qApp->setStyleSheet(qss);

        qssFile.close();

    }


 

 

qss 代码如下:
