Python QScrollArea.widget方法代码示例

class Ui_PartWindow(QWidget):
    """
    The Ui_PartWindow class provides a Part Window UI object composed of three
    primary areas:

    - The "left area" contains the Project TabWidget which contains
    the Model Tree and Property Manager (tabs). Other tabs (widgets)
    can be introduced when needed.

    - The "right area" contains the 3D Graphics Area (i.e. glpane) displaying
    the current part.

    - The "bottom area" lives below the left and right areas, spanning
    the full width of the part window. It can be used whenever a landscape
    layout is needed (i.e. the Sequence Editor). Typically, this area is
    not used.

    A "part window" splitter lives between the left and right areas that
    allow the user to resize the shared area occupied by them. There is no
    splitter between the top and bottom areas.

    This class supports and is limited to a B{Single Document Interface (SDI)}.
    In time, NE1 will migrate to and support a Multiple Document Interface (MDI)
    that will allow multiple project documents (i.e. parts, assemblies,
    simulations, text files, graphs, tables, etc. documents) to be available
    within the common workspace of the NE1 main window.
