PySide.QtGui.QStyleOptionToolBar class is used to describe the parameters for drawing a toolbar.
PySide.QtGui.QStyleOptionToolBar contains all the information that PySide.QtGui.QStyle functions need to draw PySide.QtGui.QToolBar .
For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.
PySide.QtGui.QStyleOptionToolBar class holds the lineWidth 和 midLineWidth for drawing the widget. It also stores information about which area the toolbar should be located in, whether it is movable or not, which position the toolbar line should have ( positionOfLine ), and the toolbar's position within the line ( positionWithinLine ).
In addition, the class provides a couple of enums: The QStyleOptionToolBar.ToolBarFeature enum is used to describe whether a toolbar is movable or not, and the QStyleOptionToolBar.ToolBarPosition enum is used to describe the position of a toolbar line, as well as the toolbar's position within the line.
