     Qt实际库里的自带组件的样式是系统标准的,要得到更好看的界面,光靠库里的样式是远远不够的,样式表的出现使得使用Qt做出更加漂亮的界面成为可能。

1. Qt样式表的动态加载:

代码如下:

QFile file(":/qss/stylesheet.qss");  
file.open(QFile::ReadOnly);  
QString styleSheet = QLatin1String(file.readAll());  
qApp->setStyleSheet(styleSheet);  
file.close(); 
        通过以上代码,可将Qt的样式表动态加载到一个.qss的样式表文件中,从而更加方便代码的调试。

2.QPushButton样式

代码如下:

QWidget#centralWidget{
       border-style:solid;
	   background: transparent;
	   background-color:#DEB887;
	   
}

QPushButton#pushButton{
       background-color:#F08080;
       
}

QPushButton#pushButton_2{

       background-color:#FF8C00;
	   border-radius: 10px; 
}

QPushButton#pushButton_3{
     
       background-color:#4169E1;
}

QPushButton#pushButton_1{
       
       background-image: url(:qss/Skin/black/tools/tab-image.png);
       border-radius: 10px; 
	   border: 2px groove gray;

	   background: transparent;
	   background-color:#2F4F4F;
	   
}
QtableWidget#tableWidget:pane{

       background-color:#FFE4B5;

}
QTabBar::tab {
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
                                stop: 0 #E1E1E1, stop: 0.4 #DDDDDD,

    border-top-left-radius: 1px;
    border-top-right-radius: 1px;
    min-width: 8ex;
    padding: 2px;
	color:white;
}
 
QTabBar::tab:selected, QTabBar::tab:hover {
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
                                stop: 0 #fafafa, stop: 0.4 #f4f4f4,
                                stop: 0.5 #e7e7e7, stop: 1.0 #fafafa);
}

 QTabBar::tab:!selected {
    border-color: black;
	border-style:solid;
	background: transparent;
    border-bottom-color: red;
	background-image: url(:qss/Skin/black/tools/tab-image-pressed.png); 
}

 QTabBar::tab:selected {
    border-style:solid;
    border-color: black;
	background: transparent;
    border-bottom-color: red;
	background-image: url(:qss/Skin/black/tools/tab-image.png); 
}
如需要增加特殊背景,用如下方式:

代码如下:

QTabWidget#tab>QTabBar::tab:first 
{ 
border-image: url(:/Default_N.png); 
} 
QTabWidget#tab>QTabBar::tab:first:hover 
{ 
border-image: url(:/Default_P.png); 
} 
QTabWidget#tab>QTabBar::tab:first:pressed 
{ 
border-image: url(:/Default_P.png); 
} 
QTabWidget#tab>QTabBar::tab:last 
{ 
border-image: url(:/Apply_N.png); 
} 
QTabWidget#tab>QTabBar::tab:last:hover 
{ 
border-image: url(:/Apply_P.png); 
} 
QTabWidget#tab>QTabBar::tab:last:pressed 
{ 
border-image: url(:/Apply_P.png); 
}
10.其它使用细节总结:

    自定义的前台背景与后台背景的颜色:
 
如果需要样一个文本编辑器的背景变为黄色,  下面是代码行:
    qApp->setStyleSheet("QLineEdit { background-color: yellow }");
 
针对一个对话框的内容中使用 QLineEdit 以及 QLineEdit 的子类的背景都变成黄色,  下面是代码:
    
         myDialog->setStyleSheet("QLineEdit { background-color: yellow }");
 
如果只需要制定一个 QLineEdit 的内容,  将使用 QObject::setObjectName() 下面是一个实例:
  
        myDialog->setStyleSheet("QLineEdit#nameEdit { background-color: yellow }");
 
同时也可以针对每一个指定的部件做直接的类型设置,  下面是一个实例:
 
 nameEdit->setStyleSheet("background-color: yellow");
 
为了做一个鲜明的对比,  将要为文本设置合适的颜色。
 
 nameEdit->setStyleSheet("color: blue; background-color: yellow");
 
当然最好的办法还有针对选择的文本来进行设置,  下面设置了一个选择文本的类型属性:
 nameEdit->setStyleSheet("color: blue;"
                         "background-color: yellow;"
                         "selection-color: yellow;"
                         "selection-background-color: blue;");
 
 
   在有一些情况下,  不需要用户参与,  而有软件设计人员来自己制定样式,  即使这些是有违审美角度。   下面就从应用程序开发角度来设计样式。
 
*[mandatoryField="true"] { background-color: yellow }
上面的意思是一些强制的区域是需要用 Qt 的属性管理来强制设置成为黄色的背景。
这样一些强制的部件,将需要通过函数来设置当前的属性已经被强制设置,  下面是实现的代码:
 QLineEdit *nameEdit = new QLineEdit(this);
 nameEdit->setProperty("mandatoryField", true);
 
 QLineEdit *emailEdit = new QLineEdit(this);
 emailEdit->setProperty("mandatoryField", true);
 
 QSpinBox *ageSpinBox = new QSpinBox(this);
 ageSpinBox->setProperty("mandatoryField", true);

QPushButton:

下面我们将通过一个按钮的部件来设置属性样式:

  首先来设置一下样式:
     QPushButton#evilButton { background-color: red }
  说明设置的当前的按钮为红色。   作为一个 flat 平滑的按钮时没有边界的。  下面是来改进一下对边界的设置。
 
    QPushButton#evilButton {
     background-color: red;
     border-style: outset;
     border-width: 2px;
     border-color: beige;
 }
 
     在这里设置了一个边界的类型与边界的宽度。   这样看上去就好多了,文档中无法展现图片,  有兴趣可以去 Qt的变成环境当中去尝试。即使这样设计,  按钮看上去也是显得混乱,与主部件没有办法分开。  首先是在边界设置出一个空间出来,  并且强制的制定最小宽度,与环绕的弧度,  并且提供一个按钮的字体设置,  似的按钮看上去比较好看。
 
 QPushButton#evilButton {
     background-color: red;
     border-style: outset;
     border-width: 2px;
     border-radius: 10px;
     border-color: beige;
     font: bold 14px;
     min-width: 10em;
     padding: 6px;
 }
 
 
   如此这样当我们点击按钮的时候按钮也不会发生什么样的深刻变化。   所以就需要指定一个合适的背景颜色与不一样的边界类型。
 
 QPushButton#evilButton {
     background-color: red;
     border-style: outset;
     border-width: 2px;
     border-radius: 10px;
     border-color: beige;
     font: bold 14px;
     min-width: 10em;
     padding: 6px;
 }
 QPushButton#evilButton:pressed {
     background-color: rgb(224, 0, 0);
     border-style: inset;
 }
 
指定 QPushButton 菜单指示器的子控制
 
   子控提供了访问子子元素的功能,  例如通常的时候一个按钮将会管理一个菜单,
 QPushButton#evilButton::menu-indicator {
     image: url(myindicator.png);
 }
 
同时如果美化一个按钮的话,  那么将可以通过定位符来确定美化按钮的路径,  通常可以是一个图片。
 QPushButton::menu-indicator {
     image: url(myindicator.png);
     subcontrol-position: right center;
     subcontrol-origin: padding;
     left: -2px;
 }
 
  经过以上的设置那么 QPushButton 将会在方格的中心显示一个 myindicator.png 的图片。
 
定制按钮:
 
     QPushButton {
         border: 2px solid #8f8f91;
         border-radius: 6px;
         background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
                                           stop: 0 #f6f7fa, stop: 1 #dadbde);
         min-width: 80px;
     }
 
     QPushButton:pressed {
         background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
                                           stop: 0 #dadbde, stop: 1 #f6f7fa);
     }
 
     QPushButton:flat {
         border: none; /*  没有边框的按钮  */
     }
 
     QPushButton:default {
         border-color: navy; /* 使得按钮显示变得更加突出  */
     }
 
        QPushButton:open { /* when the button has its menu open */
         background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
                                           stop: 0 #dadbde, stop: 1 #f6f7fa);
     }
 
     QPushButton::menu-indicator {
         image: url(menu_indicator.png);
         subcontrol-origin: padding;
         subcontrol-position: bottom right;
     }
 
     QPushButton::menu-indicator:pressed, QPushButton::menu-indicator:open {
         position: relative;
         top: 2px; left: 2px; /* shift the arrow by 2 px */
     }

下面的横向的slider 

    QSlider::groove:horizontal {

         height: 8px; /* the groove expands to the size of the slider by default. by giving it a height, it has a fixed size */
         background: qlineargradient(x1:0, y1:0, x2:0, y2:1, stop:0 #B1B1B1, stop:1 #c4c4c4);
         margin: 2px 0;
     }
 
     QSlider::handle:horizontal {
         background: qlineargradient(x1:0, y1:0, x2:1, y2:1, stop:0 #b4b4b4, stop:1 #8f8f8f);
         border: 1px solid #5c5c5c;
         width: 18px;
         margin: -2px 0; /* handle is placed by default on the contents rect of the groove. Expand outside the groove */
         border-radius: 3px;
     }
 
 
       QSlider::groove:vertical {
         background: red;
         position: absolute; /* absolutely position 4px from the left and right of the widget. setting margins on the widget should work too... */
         left: 4px; right: 4px;
     }
 
     QSlider::handle:vertical {
         height: 10px;
         background: green;
         margin: 0 -4px; /* expand outside the groove */
     }
 
     QSlider::add-page:vertical {
         background: white;

     QSlider::sub-page:vertical {
