QPushButton使用css设置图标和文本

平时我们设置QPushButton时只设置它的normal, hover, pressed三种状态的文本类型或者背景图片，很少用到图标和文本同时显示，本篇介绍图标和文本同时显示，并且图标可以动态调整显示位置，下面是具体的代码：

void MainWindow::initView()
{
    ui->pushButton->setStyleSheet("QPushButton{background-color: #66ffff;border-radius:5px;"
                                  "background-image: url(:/arrow_refresh16.png); "
                                  "background-origin: content;background-position: center;"
                                  "padding-right: 40px;	padding-bottom: 2px; background-repeat: no-repeat;"
                                  "text-align:top;padding-left: 2px;padding-top: 2px;"
                                  "font-size: 12px; color: #FFFFFF;}");

    ui->pushButton_2->setStyleSheet("QPushButton{background-color: #66ffff;border-radius:5px;"
                                  "background-image: url(:/arrow_refresh16.png); "
                                  "background-origin: content;background-position: center;"
                                  "padding-right: 40px;	padding-bottom: 2px; background-repeat:repeat;"
                                  "text-align:top;padding-left: 2px;padding-top: 2px;"
                                  "font-size: 12px; color: #FFFFFF;}");

    ui->pushButton_3->setStyleSheet("QPushButton{background-color: #66ffff;border-radius:5px;"
                                    "background-image: url(:/arrow_refresh16.png);"
                                    "background-origin: content; background-position: top;"
                                    "background-repeat: no-repeat;"
                                    "text-align: bottom; padding-bottom:5px;"
                                    "font-size: 12px; color: #FF0000;}");

    ui->pushButton_4->setStyleSheet("QPushButton{background-color: #66ffff;border-radius:5px;"
                                    "background-image: url(:/arrow_refresh16.png);"
                                    "background-origin: content; background-position: bottom;"
                                    "background-repeat: no-repeat;"
                                    "text-align: top; padding-top:5px;"
                                    "font-size: 12px; color: #FF0000;}");

    ui->pushButton_5->setStyleSheet("QPushButton{background-color: #66ffff;border-radius:5px;"
                                    "background-image: url(:/arrow_refresh16.png);"
                                    "background-origin: content; background-position: left;"
                                    "background-repeat: no-repeat;"
                                    "text-align: right; padding-right:5px;"
                                    "font-size: 12px; color: #FF0000;}");

    ui->pushButton_6->setStyleSheet("QPushButton{background-color: #66ffff;border-radius:5px;"
                                    "background-image: url(:/arrow_refresh16.png);"
                                    "background-origin: content; background-position: right;"
                                    "background-repeat: no-repeat;"
                                    "text-align: left; padding-top:5px;"
                                    "font-size: 12px; color: #FF0000;}");
}
