\section{\class{wxDocManager}}\label{wxdocmanager}
|
|
|
|
The wxDocManager class is part of the document/view framework supported by wxWindows,
|
|
and cooperates with the \helpref{wxView}{wxview}, \helpref{wxDocument}{wxdocument}\rtfsp
|
|
and \helpref{wxDocTemplate}{wxdoctemplate} classes.

\membersection{wxDocManager::m\_defaultDocumentNameCounter}
|
|
|
|
\member{int}{m\_defaultDocumentNameCounter}
|
|
|
|
Stores the integer to be used for the next default document name.
|
|
|
|
\membersection{wxDocManager::m\_fileHistory}
|
|
|
|
\member{wxFileHistory*}{m\_fileHistory}
|
|
|
|
A pointer to an instance of \helpref{wxFileHistory}{wxfilehistory},
|
|
which manages the history of recently-visited files on the File menu.
|
|
|
|
\membersection{wxDocManager::m\_maxDocsOpen}
|
|
|
|
\member{int}{m\_maxDocsOpen}
|
|
|
|
Stores the maximum number of documents that can be opened before
|
|
existing documents are closed. By default, this is 10,000.
|
|
|
|
\membersection{wxDocManager::m\_docs}
|
|
|
|
\member{wxList}{m\_docs}
|
|
|
|
A list of all documents.
|
|
|
|
\membersection{wxDocManager::m\_flags}
|
|
|
|
\member{long}{m\_flags}
|
|
|
|
Stores the flags passed to the constructor.
|
|
|
|
\membersection{wxDocManager::m\_lastDirectory}
|
|
|
|

|
\membersection{wxDocManager::wxDocManager}
|
|
|
|
\func{void}{wxDocManager}{\param{long}{ flags = wxDEFAULT\_DOCMAN\_FLAGS}, \param{bool}{ initialize = TRUE}}
|
|
|
|
Constructor. Create a document manager instance dynamically near the start of your application
|
|
before doing any document or view operations.
|
|
|
|
{\it flags} is currently unused.
|
|
|
|
If {\it initialize} is TRUE, the \helpref{Initialize}{wxdocmanagerinitialize} 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.
|
|
|
|
\membersection{wxDocManager::\destruct{wxDocManager}}
|
|
|
|
\func{void}{\destruct{wxDocManager}}{\void}
|
|
|
|
Destructor.
|
|
|
|
\membersection{wxDocManager::ActivateView}
|
|
|
|
\func{void}{ActivateView}{\param{wxView* }{doc}, \param{bool}{ activate}, \param{bool}{ deleting}}
|
|
|
|
Sets the current view.
|

|
|
|
|
Adds the document to the list of documents.
|
|
|
|
\membersection{wxDocManager::AddFileToHistory}
|
|
|
|
\func{void}{AddFileToHistory}{\param{const wxString\& }{filename}}
|
|
|
|
Adds a file to the file history list, if we have a pointer to an appropriate file menu.
|
|
|
|
\membersection{wxDocManager::AssociateTemplate}
|
|
|
|
\func{void}{AssociateTemplate}{\param{wxDocTemplate *}{temp}}
|
|
|
|
Adds the template to the document manager's template list.
|
|
|
|
\membersection{wxDocManager::CreateDocument}
|
|
|
|
\func{wxDocument*}{CreateDocument}{\param{const wxString\& }{path}, \param{long}{ flags}}
|
|
|
|
Creates a new document in a manner determined by the {\it flags} parameter, which can be:
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
\item wxDOC\_NEW Creates a fresh document.
|
|
\item wxDOC\_SILENT Silently loads the given document file.
|
|
\end{itemize}
|
|
|
|
If wxDOC\_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 wxDOC\_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.
|
|
|
|
\membersection{wxDocManager::CreateView}
|
|
|
|
\func{wxView*}{CreateView}{\param{wxDocument*}{doc}, \param{long}{ flags}}
|
|
|
|
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.
|
|
|
|
\membersection{wxDocManager::DisassociateTemplate}
|
|
|
|
\func{void}{DisassociateTemplate}{\param{wxDocTemplate *}{temp}}
|
|
|
|
Removes the template from the list of templates.
|
|
|
|

|
|
|
|
\func{void}{FileHistoryAddFilesToMenu}{\void}
|
|
|
|

|
\membersection{wxDocManager::FileHistorySave}\label{wxdocmanagerfilehistorysave}
|
|
|
|
\func{void}{FileHistorySave}{\param{wxConfigBase\& }{resourceFile}}

|
|
explicitly by the application.
|
|
|
|

|
|
\membersection{wxDocManager::FileHistoryUseMenu}\label{wxdocmanagerfilehistoryusemenu}
|
|
|
|
\func{void}{FileHistoryUseMenu}{\param{wxMenu*}{ menu}}
|
|
|
|
Use this menu for appending recently-visited document filenames, for convenient
|
|
access. Calling this function with a valid menu pointer enables the history
|
|
list functionality.
|
|
|
|
Note that you can add multiple menus using this function, to be managed by the
|
|
file history object.
|
|
|
|
\membersection{wxDocManager::FindTemplateForPath}
|
|
|
|
\func{wxDocTemplate *}{FindTemplateForPath}{\param{const wxString\& }{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.
|
|
|
|
\membersection{wxDocManager::GetCurrentDocument}
|
|
|
|
\func{wxDocument *}{GetCurrentDocument}{\void}
|
|
|
|
Returns the document associated with the currently active view (if any).
|
|
|
|
\membersection{wxDocManager::GetCurrentView}
|
|
|
|
\func{wxView *}{GetCurrentView}{\void}
|
|
|
|
Returns the currently active view
|
|
|
|
\membersection{wxDocManager::GetDocuments}
|
|
|
|
\func{wxList\&}{GetDocuments}{\void}
|
|
|
|
Returns a reference to the list of documents.
|
|
|
|
\membersection{wxDocManager::GetFileHistory}
|
|
|
|
\func{wxFileHistory *}{GetFileHistory}{\void}
|
|
|
|
Returns a pointer to file history.
|
|
|
|
\membersection{wxDocManager::GetLastDirectory}\label{wxdocmanagergetlastdirectory}
|
|
|
|
\constfunc{wxString}{GetLastDirectory}{\void}
|
|
|
|
Returns the directory last selected by the user when opening a file. Initially empty.
|
|
|
|
\membersection{wxDocManager::GetMaxDocsOpen}
|
|
|
|
\func{int}{GetMaxDocsOpen}{\void}
|
|
|
|
Returns the number of documents that can be open simultaneously.
|
|
|
|
\membersection{wxDocManager::GetNoHistoryFiles}
|
|
|
|
\func{int}{GetNoHistoryFiles}{\void}
|
|
|
|
Returns the number of files currently stored in the file history.
|
|
|
|
\membersection{wxDocManager::Initialize}\label{wxdocmanagerinitialize}
|
|
|
|
\func{bool}{Initialize}{\void}
|
|
|
|
Initializes data; currently just calls OnCreateFileHistory. Some data cannot
|
|
always be initialized in the constructor because the programmer must be given
|
|
the opportunity to override functionality. If OnCreateFileHistory was called
|
|
from the constructor, an overridden virtual OnCreateFileHistory would not be
|
|
called due to C++'s `interesting' constructor semantics. In fact Initialize
|
|
\rtfsp{\it is} called from the wxDocManager 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 OnCreateFileHistory
|
|
from the default.
|
|
|
|
The bottom line: if you're not deriving from Initialize, forget it and
|
|
construct wxDocManager with no arguments.
|
|
|
|
\membersection{wxDocManager::MakeDefaultName}
|
|
|
|
\func{bool}{MakeDefaultName}{\param{const wxString\& }{buf}}
|
|
|
|
Copies a suitable default name into {\it buf}. This is implemented by
|
|
appending an integer counter to the string {\bf unnamed} and incrementing
|
|
the counter.
|
|
|
|
\membersection{wxDocManager::OnCreateFileHistory}
|
|
|
|
\func{wxFileHistory *}{OnCreateFileHistory}{\void}
|
|
|
|
A hook to allow a derived class to create a different type of file history. Called
|
|
from \helpref{Initialize}{wxdocmanagerinitialize}.
|
|
|
|
\membersection{wxDocManager::OnFileClose}
|
|
|
|
\func{void}{OnFileClose}{\void}
|
|
|
|
Closes and deletes the currently active document.
|
|
|
|
\membersection{wxDocManager::OnFileNew}
|
|
|
|
\func{void}{OnFileNew}{\void}
|
|
|
|
Creates a document from a list of templates (if more than one template).
|
|
|
|
\membersection{wxDocManager::OnFileOpen}
|
|
|
|
\func{void}{OnFileOpen}{\void}
|
|
|
|
Creates a new document and reads in the selected file.
|
|
|
|
\membersection{wxDocManager::OnFileSave}
|
|
|
|
\func{void}{OnFileSave}{\void}
|
|
|
|
Saves the current document by calling wxDocument::Save for the current document.
|
|
|
|
\membersection{wxDocManager::OnFileSaveAs}
|
|
|
|
\func{void}{OnFileSaveAs}{\void}
|
|
|
|
Calls wxDocument::SaveAs for the current document.
|
|
|
|
\membersection{wxDocManager::OnMenuCommand}
|
|
|
|
\func{void}{OnMenuCommand}{\param{int}{ cmd}}
|
|
|
|
Processes menu commands routed from child or parent frames. This deals
|
|
with the following predefined menu item identifiers:
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
\item wxID\_OPEN Creates a new document and opens a file into it.
|
|
\item wxID\_CLOSE Closes the current document.
|
|
\item wxID\_NEW Creates a new document.
|
|
\item wxID\_SAVE Saves the document.
|
|
\item wxID\_SAVE\_AS Saves the document into a specified filename.
|
|
\end{itemize}
|
|
|
|
Unrecognized commands are routed to the currently active wxView's OnMenuCommand.
|
|
|
|
\membersection{wxDocManager::RemoveDocument}
|
|
|
|
\func{void}{RemoveDocument}{\param{wxDocument *}{doc}}
|
|
|
|
Removes the document from the list of documents.
|
|
|
|
\membersection{wxDocManager::SelectDocumentPath}
|
|
|
|
\func{wxDocTemplate *}{SelectDocumentPath}{\param{wxDocTemplate **}{templates},
|
|
\param{int}{ noTemplates}, \param{const wxString\& }{path}, \param{const wxString\& }{bufSize},
|
|
\param{long}{ flags}, \param{bool}{ 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 wxDocManager::CreateDocument.
|
|
|
|
\membersection{wxDocManager::SelectDocumentType}
|
|
|
|
\func{wxDocTemplate *}{SelectDocumentType}{\param{wxDocTemplate **}{templates},
|
|
\param{int}{ noTemplates}}
|
|
|
|
Returns a document template by asking the user (if there is more than one template).
|
|
This function is used in wxDocManager::CreateDocument.
|
|
|
|
\membersection{wxDocManager::SelectViewType}
|
|
|
|
\func{wxDocTemplate *}{SelectViewType}{\param{wxDocTemplate **}{templates},
|
|
\param{int}{ noTemplates}}
|
|
|
|
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 won't appear because the array of templates only contains
|
|
those relevant to the document in question, and often there will only be one such.
|
|
|
|
\membersection{wxDocManager::SetLastDirectory}\label{wxdocmanagersetlastdirectory}
|
|
|
|
\func{void}{SetLastDirectory}{\param{const wxString\&}{ dir}}
|
|
|
|
Sets the directory to be displayed to the user when opening a file. Initially this is empty.
|
|
|
|
\membersection{wxDocManager::SetMaxDocsOpen}
|
|
|
|
\func{void}{SetMaxDocsOpen}{\param{int}{ n}}
|
|
|
|
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.
