QSurface ¶

概要 ¶

详细描述 ¶

表面尺寸是可访问的，采用 size() function. The rendering specific attributes of the surface are accessible through the format() 函数。

class QSurface ( type ) ¶

param type

SurfaceClass

创建表面，采用给定 type .

PySide2.QtGui.QSurface. SurfaceClass ¶

The enum describes the actual subclass of the surface.

常量	描述
QSurface.Window	The surface is an instance of QWindow .
QSurface.Offscreen	The surface is an instance of QOffscreenSurface .

PySide2.QtGui.QSurface. SurfaceType ¶

The enum describes what type of surface this is.

常量	描述
QSurface.RasterSurface	The surface is is composed of pixels and can be rendered to using a software rasterizer like Qt’s raster paint engine.
QSurface.OpenGLSurface	The surface is an OpenGL compatible surface and can be used in conjunction with QOpenGLContext .
QSurface.RasterGLSurface	The surface can be rendered to using a software rasterizer, and also supports OpenGL. This surface type is intended for internal Qt use, and requires the use of private API.
QSurface.OpenVGSurface	The surface is an OpenVG compatible surface and can be used in conjunction with OpenVG contexts.
QSurface.VulkanSurface	The surface is a Vulkan compatible surface and can be used in conjunction with the Vulkan graphics API.
QSurface.MetalSurface	The surface is a Metal compatible surface and can be used in conjunction with Apple’s Metal graphics API. This surface type is supported on macOS only.
