## Detailed Description
该QGroupBox小部件提供一个带标题的分组框框架。
一组框提供了一个框架，一个标题和一个键盘快捷键，并显示其自身内部的各种其他部件。标题是在顶部，键盘快捷键将键盘焦点移至该组框的子控件之一。
QGroupBox也可以让你设置[title](qgroupbox.html#title-prop)（通常是在构造函数中设置）和标题的[alignment](qgroupbox.html#alignment-prop)。组框可以[checkable](qgroupbox.html#checkable-prop)，在可复组框子控件可以启用或禁用依赖于组框是否[checked](qgroupbox.html#checked-prop)。
您可以通过启用最小化组框的空间消耗的[flat](qgroupbox.html#flat-prop)属性。在大多数[styles](qstyle.html)，从而使该属性的结果中去除左侧，框架的右边缘和下边缘的。
QGroupBox不会自动布局的子控件（通常是[QCheckBox](qcheckbox.html)ES或[QRadioButton](qradiobutton.html)s，但可以是任何小部件） 。下面的例子展示了如何建立一个QGroupBox与布局：
```
QGroupBox *groupBox = new QGroupBox(tr("Exclusive Radio Buttons"));
[QRadioButton](qradiobutton.html) *radio1 = new [QRadioButton](qradiobutton.html)(tr("&Radio button 1"));
[QRadioButton](qradiobutton.html) *radio2 = new [QRadioButton](qradiobutton.html)(tr("R&adio button 2"));
[QRadioButton](qradiobutton.html) *radio3 = new [QRadioButton](qradiobutton.html)(tr("Ra&dio button 3"));
radio1->setChecked(true);
[QVBoxLayout](qvboxlayout.html) *vbox = new [QVBoxLayout](qvboxlayout.html);
vbox->addWidget(radio1);
vbox->addWidget(radio2);
vbox->addWidget(radio3);
vbox->addStretch(1);
groupBox->setLayout(vbox);
```

## Qt Signal Documentation
```
void clicked (bool = 0)
```
这是该信号的默认超载。
当复选框被激活（即按下然后释放，而鼠标光标在按钮内） ，或当快捷键打字，值得注意的是，该信号是这个信号被发射_not_如果你调用发出[setChecked](qgroupbox.html#checked-prop)（ ） 。
如果复选框被选中_checked_是真的，它是假的，如果未选中此复选框。
这个函数中引入了Qt 4.2中。
**See also** [checkable](qgroupbox.html#checkable-prop)，[toggled](qgroupbox.html#toggled)（）和[checked](qgroupbox.html#checked-prop)。
```
void toggled (bool)
```
这是该信号的默认超载。
如果该组框是可复，此信号时，该复选框被触发发出。_on_是真的，如果该复选框被选中，否则为假。
