详细描述 ¶

QMenu uses this to “raise” the menu above the surrounding screen. QProgressBar has a “sunken” look. QLabel 拥有 Flat (扁平) 外观。像这些的 Widget 框架可以改变。
label = QLabel()
label.setFrameStyle(QFrame.Panel | QFrame.Raised)
label.setLineWidth(2)
pbar = QProgressBar()
label.setFrameStyle(QFrame.NoFrame)
											
QFrame class can also be used directly for creating simple placeholder frames without any contents.

框架样式的指定通过 frame shape 和 shadow style 用于在视觉上分隔框架与周围 Widget。这些特性可以一起设置使用 setFrameStyle() function and read with frameStyle() .

框架形状包括 NoFrame , Box , Panel , StyledPanel , HLine and VLine ；阴影样式包括 Plain , Raised and Sunken .

框架 Widget 拥有 3 个描述边框厚度的属性： lineWidth , midLineWidth ，和 frameWidth .

The line width is the width of the frame border. It can be modified to customize the frame’s appearance.

中线宽度指定框架中间额外线条的宽度，使用第 3 种颜色以获得特殊 3D 效果。注意：只绘制中线对于 Box , HLine and VLine 凸起或凹陷框架。

框架宽度由框架样式确定，和 frameWidth() function is used to obtain the value defined for the style used.

定制框架和框架内容之间的边距采用 setContentsMargins() 函数。

此表展示一些样式和线宽的组合：

class QFrame ( [ parent=None [ , f=Qt.WindowFlags() ] ] ) ¶

param f

WindowFlags

param parent

QWidget

构造框架 Widget 采用框架样式 NoFrame 和 1 像素框架宽度。

parent and f 自变量被传递给 QWidget 构造函数。

PySide2.QtWidgets.QFrame. 形状 ¶

此枚举类型定义框架可用形状。

常量	描述
QFrame.NoFrame	`QFrame` 什么都不绘制
QFrame.Box	`QFrame` 在其内容周围绘制方框
QFrame.Panel	`QFrame` 绘制平面以使内容看起来凸起 (或凹陷)
QFrame.StyledPanel	绘制外观从属当前 GUI 样式的矩形面板。可以凸起或凹陷。
QFrame.HLine	`QFrame` 绘制无边框水平线 (作为分隔符很有用)
QFrame.VLine	`QFrame` 绘制无边框垂直线 (作为分隔符很有用)
QFrame.WinPanel	draws a rectangular panel that can be raised or sunken like those in Windows 2000. Specifying this shape sets the line width to 2 pixels. is provided for compatibility. For GUI style independence we recommend using instead.

当不调用 QStyle ，形状交互影响 Shadow ， lineWidth() 和 midLineWidth() to create the total result. See the picture of the frames in the main class documentation.

PySide2.QtWidgets.QFrame. Shadow ¶

此枚举类型定义用于把 3D 效果给予框架的阴影类型。

常量	描述
QFrame.Plain	the frame and contents appear level with the surroundings; draws using the palette `WindowText` color (without any 3D effect)
QFrame.Raised	the frame and contents appear raised; draws a 3D raised line using the light and dark colors of the current color group
QFrame.Sunken	the frame and contents appear sunken; draws a 3D sunken line using the light and dark colors of the current color group
