ComboBox (parent = None, items = None, default = None,) [source] # Extends QComboBox to add extra functionality. Fortunately, the library provides several options that will allow us to 文章浏览阅读2. 学习PyQtGraph最简单的方法是浏览示例；运行 python -m pyqtgraph. Options are ‘vertical’ or ‘horizontal’ The default is ‘vertical’, indicating that the region is bounded by vertical lines. The UML class diagram below gives an overview of the most important classes and their relations. The 3D graphics system in pyqtgraph is composed of a view widget and several graphics items (all subclasses of GLGraphicsItem) which can be added to a view widget. __init__ ( parent = None, ** opts,) [source] # Arrows can be initialized with any keyword arguments accepted by the setStyle() method.
