void	UnRef ()
	Decrements the reference count in the associated data, and if it is zero, deletes the data.

Member Enumeration Documentation

anonymous enum

The elements of this enum determine what happens if GetIcon() doesn't find the icon of exactly the requested size.

Since: 2.9.4

Enumerator:

FALLBACK_NONE

Return invalid icon if exact size is not found.

FALLBACK_SYSTEM

Return the icon of the system icon size if exact size is not found.

May be combined with other non-NONE enum elements to determine what happens if the system icon size is not found neither.

FALLBACK_NEAREST_LARGER

Return the icon of closest larger size or, if there is no icon of larger size in the bundle, the closest icon of smaller size.

Constructor & Destructor Documentation

wxIconBundle::wxIconBundle ( )

Default ctor.

wxIconBundle::wxIconBundle	(	const wxString &	file,
		wxBitmapType	type = `wxBITMAP_TYPE_ANY`
	)

Initializes the bundle with the icon(s) found in the file.

wxIconBundle::wxIconBundle	(	wxInputStream &	stream,
		wxBitmapType	type = `wxBITMAP_TYPE_ANY`
	)

Initializes the bundle with the icon(s) found in the stream.

Notice that the stream must be seekable, at least if it contains more than one icon. The stream pointer is positioned after the last icon read from the stream when this function returns.

Since: 2.9.0

wxIconBundle::wxIconBundle ( const wxIcon & icon )

Initializes the bundle with a single icon.

wxIconBundle::wxIconBundle ( const wxIconBundle & ic )

Copy constructor.

virtual wxIconBundle::~wxIconBundle ( )

virtual

Destructor.

Member Function Documentation

void wxIconBundle::AddIcon	(	const wxString &	file,
		wxBitmapType	type = `wxBITMAP_TYPE_ANY`
	)

Adds all the icons contained in the file to the bundle; if the collection already contains icons with the same width and height, they are replaced by the new ones.

void wxIconBundle::AddIcon	(	wxInputStream &	stream,
		wxBitmapType	type = `wxBITMAP_TYPE_ANY`
	)

Adds all the icons contained in the stream to the bundle; if the collection already contains icons with the same width and height, they are replaced by the new ones.

Notice that, as well as in the constructor loading the icon bundle from stream, the stream must be seekable, at least if more than one icon is to be loaded from it.

Since: 2.9.0

void wxIconBundle::AddIcon ( const wxIcon & icon )

Adds the icon to the collection; if the collection already contains an icon with the same width and height, it is replaced by the new one.

wxIcon wxIconBundle::GetIcon	(	const wxSize &	size,
		int	flags = `FALLBACK_SYSTEM`
	)		const

Returns the icon with the given size.

If size is wxDefaultSize, it is interpreted as the standard system icon size, i.e. the size returned by wxSystemSettings::GetMetric() for wxSYS_ICON_X and wxSYS_ICON_Y.

If the bundle contains an icon with exactly the requested size, it's always returned. Otherwise, the behaviour depends on the flags. If only wxIconBundle::FALLBACK_NONE is given, the function returns an invalid icon. If wxIconBundle::FALLBACK_SYSTEM is given, it tries to find the icon of standard system size, regardless of the size passed as parameter. Otherwise, or if the icon system size is not found neither, but wxIconBundle::FALLBACK_NEAREST_LARGER flag is specified, the function returns the smallest icon of the size larger than the requested one or, if this fails too, just the icon closest to the specified size.

The flags parameter is available only since wxWidgets 2.9.4.

wxIcon wxIconBundle::GetIcon	(	wxCoord	size = `wxDefaultCoord`,
		int	flags = `FALLBACK_SYSTEM`
	)		const

Same as.

GetIcon( wxSize( size, size ) )

.

wxIcon wxIconBundle::GetIconByIndex ( size_t n ) const

return the icon at index (must be < GetIconCount())

size_t wxIconBundle::GetIconCount ( ) const

return the number of available icons

wxIcon wxIconBundle::GetIconOfExactSize ( const wxSize & size ) const

Returns the icon with exactly the given size or wxNullIcon if this size is not available.

bool wxIconBundle::IsEmpty ( ) const

Returns true if the bundle doesn't contain any icons, false otherwise (in which case a call to GetIcon() with default parameter should return a valid icon).

wxIconBundle& wxIconBundle::operator= ( const wxIconBundle & ic )

Assignment operator, using reference counting.
