QGroupBox ¶

概要 ¶

详细描述 ¶

A group box provides a frame, a title on top, a keyboard shortcut, and displays various other widgets inside itself. The keyboard shortcut moves keyboard focus to one of the group box’s child widgets.

QGroupBox also lets you set the title (normally set in the constructor) and the title’s alignment . Group boxes can be checkable . Child widgets in checkable group boxes are enabled or disabled depending on whether or not the group box is checked .

You can minimize the space consumption of a group box by enabling the flat property. In most styles , enabling this property results in the removal of the left, right and bottom edges of the frame.

QGroupBox doesn’t automatically lay out the child widgets (which are often QCheckBox es or QRadioButton s but can be any widgets). The following example shows how we can set up a QGroupBox with a layout:

groupBox = QGroupBox("Exclusive Radio Buttons")
radio1 = QRadioButton("&Radio button 1")
radio2 = QRadioButton("R&adio button 2")
radio3 = QRadioButton("Ra&dio button 3")
radio1.setChecked(True)
vbox = QVBoxLayout()
vbox.addWidget(radio1)
vbox.addWidget(radio2)
vbox.addWidget(radio3)
vbox.addStretch(1)
groupBox.setLayout(vbox)
