Qt StyleSheet样式表实例
在涉及到Qt 美工的时候首先需要掌握CSS级联样式表。
下面将通过几个例子来介绍一下怎样使用Qt中的部件类型设计。自定义的前台背景与后台背景的颜色：
如果需要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：
ui.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 * evilButton= new QPushButton (this);
evilButton ->setText("Button");
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- 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- 2px;
border-radius: 6px;
border-color: beige;
font: bold 14px;
min- 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- 2px;
border-radius: 10px;
border-color: beige;
font: bold 14px;
min- 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。
复杂区域的例子：
当应对于一个用户可编辑可输入的部件的时候， 将需要设计到用户选择区域的颜色设置，与类型设置， 下面将通过使用QLineEdit 部件来进行演示：
QLineEdit { color:red }
QLineEdit[readOnly="true"]{color:gray}
在团队开发的时候， 需要设计到不同颜色的设置，或者说不同类型的设置，那么就需要在样式编辑当中有多种选择，将不需要的那部分，注释掉：
QLineEdit { color:red }
QLineEdit[readOnly="true"]{ color: gray }
#registrationDialogQLineEdit { color: brown }
自定义制定的部件
这个部分提供了一些自定义特殊部件的某种样式
定制QAbstractScrollArea
比如说一些QAbstractScrollArea 类， 例如 QTextEdit 与QTextBrowser . 同时可以使用后台的属性来进行设置。 例如来设置一个背景图片。
QTextEdit,QListView {
background-color: white;
background-image: url(draft.png);
background-attachment: scroll;
}
下面的代码是让背景图片与可浏览的区域大小相同：
QTextEdit,QListView {
background-color: white;
background-image: url(draft.png);
background-attachment: fixed;
}
QCheckBox 与QRadioButton 具有想色的属性， 他们之间的不同时QCheckBox是返回当前的状态：
QCheckBox {
spacing: 5px;
}
QCheckBox::indicator{
13px;
height: 13px;
}
QCheckBox::indicator:unchecked{
image: url(:/images/checkbox_unchecked.png);
}
QCheckBox::indicator:unchecked:hover{
image:url(:/images/checkbox_unchecked_hover.png);
}
QCheckBox::indicator:unchecked:pressed{
image:url(:/images/checkbox_unchecked_pressed.png);
}
QCheckBox::indicator:checked{
image: url(:/images/checkbox_checked.png);
}
QCheckBox::indicator:checked:hover{
image:url(:/images/checkbox_checked_hover.png);
}
QCheckBox::indicator:checked:pressed{
image:url(:/images/checkbox_checked_pressed.png);
}
QCheckBox::indicator:indeterminate:hover{
image:url(:/images/checkbox_indeterminate_hover.png);
}
QCheckBox::indicator:indeterminate:pressed{
image:url(:/images/checkbox_indeterminate_pressed.png);
}
下面是对QComboBox下拉列表框进行的样式设计：

min- 6em;

}
/* QComboBox gets the "on" statewhen the popup is open */
QComboBox:!editable:on,QComboBox::drop-down:editable:on {

定制ScrollBar
下面是一个填充的实体的灰色边框的滚动条
QScrollBar:horizontal{

}
QScrollBar::handle:horizontal{
background: white;
min- 20px;
}
QScrollBar::add-line:horizontal{
border: 2px solid grey;
background: #32CC99;
20px;

subcontrol-origin: margin;
}
QScrollBar::sub-line:horizontal{
border: 2px solid grey;
background: #32CC99;
20px;
subcontrol-position: left;

}
左箭头与右箭头都分别设置成为灰色的边框与白色的背景，所以，两边都可以设置一个嵌入的图片。

border: 2px solid grey;
3px;
height: 3px;
background: white;
}

如果希望两个箭头都在同一个方向，例如苹果机的界面， 将使用下面的设置模式：
QScrollBar:horizontal{
border: 2px solid green;
background: cyan;
height: 15px;
margin: 0px 40px 0 0px;
}
QScrollBar::handle:horizontal{
background: gray;
min- 20px;
}
QScrollBar::add-line:horizontal{
background: blue;
16px;
subcontrol-position: right;
subcontrol-origin: margin;
border: 2px solid black;
}
QScrollBar::sub-line:horizontal{
background: magenta;
16px;
subcontrol-position: top right;
subcontrol-origin: margin;
border: 2px solid black;
position: absolute;
right: 20px;
}
QScrollBar:left-arrow:horizontal,QScrollBar::right-arrow:horizontal {

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;
18px;
margin: -2px 0; /* handle is placed bydefault on the contents rect of the groove. Expand outside the groove */
border-radius: 3px;
}
QSlider::groove:vertical{
background: red;
position: absolute; /* absolutelyposition 4px from the left and right of the widget. setting margins on thewidget should work too... */
left: 4px; right: 4px;
}
