## Detailed Description

Main Window which supports documents.

This is an abstract class. You must use a class such as App_WithDoc_Gtk, which implements the ui_* methods for a particular GUI toolkit.

Features:

- 1 document per application instance. Uses Document-derived class polymorphically.
- Override init_create_document() to create new blank document.
- Appropriate Default handling of document open, save, save as.
- Appropriate checking of document 'modified' status - asks user about unsaved changes.
- Asks user about overwriting existing documents.
- Override methods to add/change menus/toolbars/statusbar.
  - Default is basic File, Edit, Help menus and toolbar icons.
- Shows document name (or 'untitled') in window title.
- Shows * in title bar for unsaved docs. Overridable to e.g. shade a Save icon.
- Enforces a file extension.
- Recent Documents menu item - if you use add_mime_type().

TODO:

- Printing -?
  - Print Setup
  - Print Preview
  - Multiple document-types:
  - File/New sub menu
  - Some way to associate a view with a document type: class factory.

## Member Function Documentation

virtual void Bakery::App_WithDoc::init | ( |  | ) | `[virtual]`

Reimplemented from Bakery::App.

Reimplemented in Bakery::App_WithDoc_Gtk.

static bool Bakery::App_WithDoc::file_exists | ( | const Glib::ustring & | uri | ) | `[static]`

virtual void Bakery::App_WithDoc::init_create_document | ( |  | ) | `[protected, virtual]`

static void Bakery::App_WithDoc::add_mime_type | ( | const Glib::ustring & | mime_type | ) | `[static, protected]`

Add a MIME-type that this application can support.

You should also register the MIME-type when the application is installed: See http://freedesktop.org/Standards/AddingMIMETutor

virtual Document* Bakery::App_WithDoc::get_document | ( |  | ) | `[protected, virtual]`

static_cast<> or dynamic_cast<> this pointer to the correct type.

virtual const Document* Bakery::App_WithDoc::get_document | ( |  | ) | const`[protected, virtual]`

static_cast<> or dynamic_cast<> this pointer to the correct type.

virtual void Bakery::App_WithDoc::set_document_modified | ( | bool | bModified = `true` | ) | `[protected, virtual]`

virtual bool Bakery::App_WithDoc::open_document | ( | const Glib::ustring & | file_uri | ) | `[protected, virtual]`

Open the document from a file at a URI.

This will check whether the document is already open.

Returns:
  true indicates success.

bool Bakery::App_WithDoc::open_document_from_data | ( | const guchar * | data,
|  | std::size_t | length |
| ) |  |  | `[protected]`

Open the document using the supplied document contents.

Unlike open_document(), this has no way to know whether the document is already open.

Parameters:

  | data | A pointer to the bytes of the document contents.
  | length | The number of bytes in the data.

Returns:
  true indicates success.

virtual void Bakery::App_WithDoc::document_history_add | ( | const Glib::ustring & | file_uri | ) | `[protected, virtual]`

Update visual status.

virtual bool Bakery::App_WithDoc::on_document_load | ( |  | ) | `[protected, virtual]`

override this to show document contents.

virtual void Bakery::App_WithDoc::offer_to_save_changes | ( |  | ) | `[protected, virtual]`

virtual void Bakery::App_WithDoc::cancel_close_or_exit | ( |  | ) | `[protected, virtual]`

Stop the File|Close or the File|Exit.

virtual void Bakery::App_WithDoc::close_mark_or_destroy | ( |  | ) | `[protected, virtual]`

destroy it or mark it for destruction.

virtual void Bakery::App_WithDoc::update_window_title | ( |  | ) | `[protected, virtual]`

Present a user interface that allows the user to select a location to save the file.

Parameters:

  | old_file_uri | The existing URI of the file, if any.

Returns:
  The URI of the file chosen by the user.

Implemented in Bakery::App_WithDoc_Gtk.
