.. class:: DocManager(wx.EvtHandler)
The :class:`DocManager` class is part of the document/view framework,
and cooperates with the :class:`View`, :class:`Document` and
:class:`DocTemplate` classes.
.. method:: __init__(self, flags=DEFAULT_DOCMAN_FLAGS, initialize=True)
Constructor. Create a document manager instance dynamically near the
start of your application before doing any document or view operations.
flags is used in the Python version to indicate whether the document
manager is in DOC_SDI or DOC_MDI mode.
If initialize is true, the Initialize function will be called to
create a default history list object. If you derive from wxDocManager,
you may wish to call the base constructor with false, and then call
Initialize in your own constructor, to allow your own Initialize or
OnCreateFileHistory functions to be called.
.. method:: ActivateView(self, view, activate=True, deleting=False)
Sets the current view.
.. method:: AddDocument(self, document)
Adds the document to the list of documents.
.. method:: AddFileToHistory(self, fileName)
Adds a file to the file history list, if we have a pointer to an
appropriate file menu.
.. method:: AssociateTemplate(self, docTemplate)
Adds the template to the document manager's template list.
.. method:: Clear(self, force=True)
Closes all currently opened document by callling :meth:`CloseDocuments`
and clears the document manager's templates.
.. method:: CloseDocument(self, doc, force=True)
Closes the specified document.
.. method:: CloseDocuments(self, force=True)
Closes all currently opened documents.
.. method:: CreateDocument(self, path, flags=0)
Creates a new document in a manner determined by the flags parameter,
which can be:
``wx.lib.docview.DOC_NEW`` Creates a fresh document.
``wx.lib.docview.DOC_SILENT`` Silently loads the given document file.
If ``wx.lib.docview.DOC_NEW`` is present, a new document will be
created and returned, possibly after asking the user for a template to
use if there is more than one document template. ``If
wx.lib.docview.DOC_SILENT`` is present, a new document will be created
and the given file loaded into it. If neither of these flags is
present, the user will be presented with a file selector for the file
to load, and the template to use will be determined by the extension
(Windows) or by popping up a template choice list (other platforms).
If the maximum number of documents has been reached, this function
will delete the oldest currently loaded document before creating a new
one.
wxPython version supports the document manager's
``wx.lib.docview.DOC_OPEN_ONCE`` and ``wx.lib.docview.DOC_NO_VIEW``
flag.
if ``wx.lib.docview.DOC_OPEN_ONCE`` is present, trying to open the
same file multiple times will just return the same document. if
``wx.lib.docview.DOC_NO_VIEW`` is present, opening a file will
generate the document, but not generate a corresponding view.
.. method:: CreateView(self, doc, flags=0)
Creates a new view for the given document. If more than one view is
allowed for the document (by virtue of multiple templates mentioning
the same document type), a choice of view is presented to the user.
.. method:: DeleteTemplate(self, template, flags)
Placeholder, not yet implemented in wxWindows.
.. method:: Destroy(self)
Destructor.
.. method:: DisassociateTemplate(self, docTemplate)
Removes the template from the list of templates.
.. method:: FileHistoryAddFilesToMenu(self, menu=None)
Appends the files in the history list, to all menus managed by the
file history object.
If menu is specified, appends the files in the history list to the
given menu only.
.. method:: FileHistoryLoad(self, config)
Loads the file history from a config object.
.. method:: FileHistoryRemoveMenu(self, menu)
Removes the given menu from the list of menus managed by the file
history object.
.. method:: FileHistorySave(self, config)
Saves the file history into a config object. This must be called
explicitly by the application.
.. method:: FileHistoryUseMenu(self, menu)
Use this menu for appending recently-visited document filenames, for
convenient access. Calling this function with a valid menu enables the
history list functionality.
Note that you can add multiple menus using this function, to be
managed by the file history object.
.. method:: FindSuitableParent(self)
Returns a parent frame or dialog, either the frame with the current
focus or if there is no current focus the application's top frame.
.. method:: FindTemplateForPath(self, path)
Given a path, try to find template that matches the extension. This is
only an approximate method of finding a template for creating a
document.
Note this wxPython version looks for and returns a default template
if no specific template is found.
.. method:: FlushDoc(self, doc)
Placeholder, not yet implemented in wxWindows.
.. method:: GetCurrentDocument(self)
Returns the document associated with the currently active view (if any).
.. method:: GetCurrentView(self)
Returns the currently active view.
.. method:: GetDocuments(self)
Returns the list of documents.
.. method:: GetFileHistory(self)
Returns the file history.
.. method:: GetFlags(self)
Returns the document manager's flags.
.. method:: GetHistoryFile(self, i)
Returns the file at index i from the file history.
.. method:: GetHistoryFilesCount(self)
Returns the number of files currently stored in the file history.
.. method:: GetLastActiveView(self)
Returns the last active view. This is used in the SDI framework where dialogs can be mistaken for a view
and causes the framework to deactivete the current view. This happens when something like a custom dialog box used
to operate on the current view is shown.
.. method:: GetMaxDocsOpen(self)
Returns the number of documents that can be open simultaneously.
.. method:: GetTemplates(self)
Returns the document manager's template list.
.. method:: Initialize(self)
Initializes data; currently just calls :meth:`OnCreateFileHistory`. Some data
cannot always be initialized in the constructor because the programmer
must be given the opportunity to override functionality. In fact
``Initialize`` is called from the :class:`DocManager` constructor, but this can
be vetoed by passing false to the second argument, allowing the
derived class's constructor to call ``Initialize``, possibly calling a
different :meth:`OnCreateFileHistory` from the default.
The bottom line: if you're not deriving from ``Initialize``, forget it and
construct :class:`DocManager` with no arguments.
.. method:: MakeDefaultName(self)
Returns a suitable default name. This is implemented by appending an
integer counter to the string "Untitled" and incrementing the counter.
.. method:: MakeFrameTitle(self)
Returns a suitable title for a document frame. This is implemented by
appending the document name to the application name.
.. method:: MatchTemplate(self, path)
Placeholder, not yet implemented in wxWindows.
.. method:: OnCreateFileHistory(self)
A hook to allow a derived class to create a different type of file

.. method:: SelectDocumentPath(self, templates, flags, save)
Under Windows, pops up a file selector with a list of filters
corresponding to document templates. The wxDocTemplate corresponding
to the selected file's extension is returned.
On other platforms, if there is more than one document template a
choice list is popped up, followed by a file selector.
This function is used in :meth:`DocManager.CreateDocument`.
.. method:: SelectDocumentType(self, temps, sort=False)
Returns a document template by asking the user (if there is more than
one template). This function is used in :methW`DocManager.CreateDocument`.
Parameters
templates - list of templates from which to choose a desired template.
sort - If more than one template is passed in in templates, then this
parameter indicates whether the list of templates that the user will
have to choose from is sorted or not when shown the choice box dialog.
Default is false.
.. method:: SelectViewType(self, temps, sort=False)
Returns a document template by asking the user (if there is
more than one template), displaying a list of valid views.
This function is used in wxDocManager::CreateView. The dialog
normally will not appear because the array of templates only
contains those relevant to the document in question, and
often there will only be one such.
.. method:: SetMaxDocsOpen(self, maxDocsOpen)
Sets the maximum number of documents that can be open at a time. By
default, this is 10,000. If you set it to 1, existing documents will
be saved and deleted when the user tries to open or create a new one
(similar to the behaviour of Windows Write, for example). Allowing
multiple documents gives behaviour more akin to MS Word and other
Multiple Document Interface applications.
