This should normally be constructed as a temporary stack object; don't store a :ref:`wx.ScreenDC` object.

:meth:`~wx.ScreenDC.__init__` Constructor.
:meth:`~wx.ScreenDC.EndDrawingOnTop` Use this in conjunction with :meth:`~ScreenDC.StartDrawingOnTop` .
:meth:`~wx.ScreenDC.StartDrawingOnTop` Use this in conjunction with :meth:`~ScreenDC.EndDrawingOnTop` to ensure that drawing to the screen occurs on top of existing windows.

|api| Class API
===============
.. class:: wx.ScreenDC(DC)
**Possible constructors**::
ScreenDC()
A ScreenDC can be used to paint on the screen.
.. method:: __init__(self)
Constructor.
.. staticmethod:: EndDrawingOnTop()
Use this in conjunction with :meth:`StartDrawingOnTop` .
This function destroys the temporary window created to implement on-top drawing (X only).
:rtype: `bool`
.. staticmethod:: StartDrawingOnTop(*args, **kw)
|overload| Overloaded Implementations:
**~~~**
**StartDrawingOnTop** `(window)`
Use this in conjunction with :meth:`EndDrawingOnTop` to ensure that drawing to the screen occurs on top of existing windows.
Without this, some window systems (such as X) only allow drawing to take place underneath other windows.
This version of :meth:`StartDrawingOnTop` is used to specify that the area that will be drawn on coincides with the given window. It is recommended that an area of the screen is specified with :meth:`StartDrawingOnTop` because with large regions, flickering effects are noticeable when destroying the temporary transparent window used to implement this feature.
You might use this function when implementing a drag feature, for example as in the :ref:`wx.SplitterWindow` implementation.
:param `window`:
:type `window`: wx.Window
:rtype: `bool`
.. note::
This function is probably obsolete since the X implementations allow drawing directly on the screen now. However, the fact that this function allows the screen to be refreshed afterwards, may be useful to some applications.
**~~~**
**StartDrawingOnTop** `(rect=None)`
Use this in conjunction with :meth:`EndDrawingOnTop` to ensure that drawing to the screen occurs on top of existing windows.
Without this, some window systems (such as X) only allow drawing to take place underneath other windows.
This version of :meth:`StartDrawingOnTop` is used to specify an area of the screen which is to be drawn on. If ``None`` is passed, the whole screen is available. It is recommended that an area of the screen is specified with this function rather than with :meth:`StartDrawingOnTop` , because with large regions, flickering effects are noticeable when destroying the temporary transparent window used to implement this feature.
You might use this function when implementing a drag feature, for example as in the :ref:`wx.SplitterWindow` implementation.
:param `rect`:
:type `rect`: wx.Rect
:rtype: `bool`
.. note::
This function is probably obsolete since the X implementations allow drawing directly on the screen now. However, the fact that this function allows the screen to be refreshed afterwards, may be useful to some applications.
