wx.Metafile¶

A ** wx.Metafile ** represents the MS Windows metafile object, so metafile operations have no effect in X.

In wxWidgets, only sufficient functionality has been provided for copying a graphic to the clipboard; this may be extended in a future version.

Presently, the only way of creating a metafile is to use a wx.MetafileDC.

Availability

Only available for MSW.

Class Hierarchy¶

Inheritance diagram for class Metafile:

Methods Summary¶

`__init__`	Constructor.
`IsOk`	Returns `True` if the metafile is valid.
`Play`	Plays the metafile into the given device context, returning `True` if successful.
`SetClipboard`	Passes the metafile data to the clipboard.

Class API¶

class wx.Metafile(Object)¶

Possible constructors:

Metafile(filename="")

A Metafile represents the MS Windows metafile object, so metafile operations have no effect in X.

Methods¶

__init__(self, filename="")¶

Constructor.

If a filename is given, the Windows disk metafile is read in. Check whether this was performed successfully by using the IsOk member.

Parameters: filename (string) –

IsOk(self)¶

Returns True if the metafile is valid.

Return type: bool

Play(self, dc)¶

Plays the metafile into the given device context, returning True if successful.

Parameters: dc (wx.DC) –
Return type: bool

SetClipboard(self, width=0, height=0)¶

Passes the metafile data to the clipboard.

The metafile can no longer be used for anything, but the wx.Metafile object must still be destroyed by the application.

Below is an example of metafile, metafile device context and clipboard use from the hello.cpp example. Note the way the metafile dimensions are passed to the clipboard, making use of the device context’s ability to keep track of the maximum extent of drawing commands.

dc = wx.MetafileDC()
if dc.IsOk():
    self.Draw(dc)
    mf = dc.Close()
    if mf:
        mf.SetClipboard(dc.MaxX() + 10, dc.MaxY() + 10)

Parameters

width (int) –
height (int) –

Return type

bool
