-

wxArtProvider class is used to customize the look of wxWidgets application.
+
When wxWidgets needs to display an icon or a bitmap (e.g. in the standard file
dialog), it does not use a hard-coded resource but asks wxArtProvider for it
instead. This way users can plug in their own wxArtProvider class and easily
- replace standard art with their own version. All
- that is needed is to derive a class from wxArtProvider, override either its
- wxArtProvider::CreateBitmap and/or its
- wxArtProvider::CreateIconBundle methods
- and register the provider with
- wxArtProvider::Push:
-
+ replace standard art with their own version.
+
+ All that is needed is to derive a class from wxArtProvider, override either its
+ wxArtProvider::CreateBitmap and/or its wxArtProvider::CreateIconBundle methods
+ and register the provider with wxArtProvider::Push:
+
@code
- class MyProvider : public wxArtProvider
+ class MyProvider : public wxArtProvider
{
protected:
- wxBitmap CreateBitmap(const wxArtID& id,
+ wxBitmap CreateBitmap(const wxArtID& id,
const wxArtClient& client,
const wxSize size)
-
+
// optionally override this one as well
wxIconBundle CreateIconBundle(const wxArtID& id,
const wxArtClient& client)
...
wxArtProvider::Push(new MyProvider);
@endcode
-
+
If you need bitmap images (of the same artwork) that should be displayed at
- different sizes
- you should probably consider overriding wxArtProvider::CreateIconBundle
+ different sizes you should probably consider overriding wxArtProvider::CreateIconBundle
and supplying icon bundles that contain different bitmap sizes.
-
+
There's another way of taking advantage of this class: you can use it in your
- code and use
- platform native icons as provided by wxArtProvider::GetBitmap or
- wxArtProvider::GetIcon (NB: this is not yet really
- possible as of wxWidgets 2.3.3, the set of wxArtProvider bitmaps is too
- small).
-

- wxArtProvider::~wxArtProvider
- wxArtProvider::CreateBitmap
- wxArtProvider::CreateIconBundle
- wxArtProvider::Delete
- wxArtProvider::GetBitmap
- wxArtProvider::GetIconBundle
- wxArtProvider::GetIcon
- wxArtProvider::Insert
- wxArtProvider::Pop
- wxArtProvider::Push
- wxArtProvider::Remove

+ code and use platform native icons as provided by wxArtProvider::GetBitmap or
+ wxArtProvider::GetIcon.
+
+ @todo IS THIS NB TRUE?
+ (NB: this is not yet really possible as of wxWidgets 2.3.3, the set of wxArtProvider
+ bitmaps is too small).
+
+ @section wxartprovider_identify Identifying art resources
+
Every bitmap and icon bundle are known to wxArtProvider under an unique ID that
- is used when
- requesting a resource from it. The ID is represented by wxArtID type and can
- have one of these predefined values (you can see bitmaps represented by these
- constants in the artprov sample):
-
- wxART_ERROR
- wxART_QUESTION
- wxART_WARNING
- wxART_INFORMATION
- wxART_ADD_BOOKMARK
- wxART_DEL_BOOKMARK
- wxART_HELP_SIDE_PANEL
- wxART_HELP_SETTINGS
- wxART_HELP_BOOK
- wxART_HELP_FOLDER
- wxART_HELP_PAGE
- wxART_GO_BACK
- wxART_GO_FORWARD
- wxART_GO_UP
- wxART_GO_DOWN
- wxART_GO_TO_PARENT
- wxART_GO_HOME
- wxART_PRINT
- wxART_HELP
- wxART_TIP
- wxART_REPORT_VIEW
- wxART_LIST_VIEW
- wxART_NEW_DIR
- wxART_FOLDER
- wxART_FOLDER_OPEN
- wxART_GO_DIR_UP
- wxART_EXECUTABLE_FILE
- wxART_NORMAL_FILE
- wxART_TICK_MARK
- wxART_CROSS_MARK
- wxART_MISSING_IMAGE
- wxART_NEW
- wxART_FILE_OPEN
- wxART_FILE_SAVE
- wxART_FILE_SAVE_AS
- wxART_DELETE
- wxART_COPY
- wxART_CUT
- wxART_PASTE
- wxART_UNDO
- wxART_REDO
- wxART_QUIT
- wxART_FIND
- wxART_FIND_AND_REPLACE
- wxART_HARDDISK
- wxART_FLOPPY
- wxART_CDROM
- wxART_REMOVABLE
-
-
- Additionally, any string recognized by custom art providers registered using
+ is used when requesting a resource from it. The ID is represented by wxArtID type
+ and can have one of these predefined values (you can see bitmaps represented by these
+ constants in the @ref page_utils_samples_artprovider):

+
+ Additionally, any string recognized by custom art providers registered using
wxArtProvider::Push may be used.
-
+
+ @note
+ When running under GTK+ 2, GTK+ stock item IDs (e.g. @c "gtk-cdrom") may be used
+ as well. Additionally, if wxGTK was compiled against GTK+ >= 2.4, then it is also
+ possible to load icons from current icon theme by specifying their name (without
+ extension and directory components).
+ Icon themes recognized by GTK+ follow the freedesktop.org Icon Themes specification
+ (see http://freedesktop.org/Standards/icon-theme-spec).
+ Note that themes are not guaranteed to contain all icons, so wxArtProvider may
+ return ::wxNullBitmap or ::wxNullIcon.
+ The default theme is typically installed in @c /usr/share/icons/hicolor.
+
+
+ @section wxartprovider_clients Clients
+
+ Client is the entity that calls wxArtProvider's GetBitmap or GetIcon function.
+ It is represented by wxClientID type and can have one of these values:
+
+ @li wxART_TOOLBAR
+ @li wxART_MENU
+ @li wxART_BUTTON
+ @li wxART_FRAME_ICON
+ @li wxART_CMN_DIALOG
+ @li wxART_HELP_BROWSER
+ @li wxART_MESSAGE_BOX
+ @li wxART_OTHER (used for all requests that don't fit into any of the
+ categories above)
+
+ Client ID servers as a hint to wxArtProvider that is supposed to help it to
+ choose the best looking bitmap. For example it is often desirable to use
+ slightly different icons in menus and toolbars even though they represent
+ the same action (e.g. wxART_FILE_OPEN). Remember that this is really only a
+ hint for wxArtProvider -- it is common that wxArtProvider::GetBitmap returns
+ identical bitmap for different client values!
