/**

@class wxArtProvider
|
|
|
|
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():
|
|
|
|
@code
|
|
class MyProvider : public wxArtProvider
|
|
{
|
|
protected:
|
|
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
|
|
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.
|
|
|
|
@section artprovider_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 the ::wxArtID type
|
|
and can have one of these predefined values (you can see bitmaps represented by these
|
|
constants in the @ref page_samples_artprov):
|
|
|
|

|

</td></tr>
|
|
</table>
|
|
|
|
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:
|
|
@code
|
|
#ifdef __WXGTK__
|
|
wxBitmap bmp = wxArtProvider::GetBitmap("gtk-cdrom", wxART_MENU);
|
|
#endif
|
|
@endcode
|
|
For a list of the GTK+ stock items please refer to the GTK+ documentation page
|
|
http://library.gnome.org/devel/gtk/stable/gtk-Stock-Items.html.
|
|
It is also possible to load icons from the 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 artprovider_clients Clients
|
|
|
|
The @e 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 serve 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!
