Detailed Description

This class allows to show the user a message non intrusively.

Currently it is implemented natively for Windows and GTK and uses (non-modal) dialogs for the display of the notifications under the other platforms.

Notice that this class is not a window and so doesn't derive from wxWindow.

Member Enumeration Documentation

anonymous enum

Possible values for Show() timeout.

Enumerator
Timeout_Auto	Notification will be hidden automatically.
Timeout_Never	Notification will never time out.

Constructor & Destructor Documentation

wxNotificationMessage::wxNotificationMessage ( )

Default constructor, use SetParent(), SetTitle() and SetMessage() to initialize the object before showing it.

wxNotificationMessage::wxNotificationMessage	(	const wxString &	title,
		const wxString &	message = `wxEmptyString`,
		wxWindow *	parent = `NULL`,
		int	flags = `wxICON_INFORMATION`
	)

Create a notification object with the given attributes.

See SetTitle(), SetMessage(), SetParent() and SetFlags() for the description of the corresponding parameters.

virtual wxNotificationMessage::~wxNotificationMessage ( )

virtual

Destructor does not hide the notification.

The notification can continue to be shown even after the C++ object was destroyed, call Close() explicitly if it needs to be hidden.

Member Function Documentation

virtual bool wxNotificationMessage::Close ( )

virtual

Hides the notification.

Returns true if it was hidden or false if it couldn't be done (e.g. on some systems automatically hidden notifications can't be hidden manually).

void wxNotificationMessage::SetFlags ( int flags )

This parameter can be currently used to specify the icon to show in the notification.

Valid values are wxICON_INFORMATION, wxICON_WARNING and wxICON_ERROR (notice that wxICON_QUESTION is not allowed here). Some implementations of this class may not support the icons.

void wxNotificationMessage::SetMessage ( const wxString & message )

Set the main text of the notification.

This should be a more detailed description than the title but still limited to reasonable length (not more than 256 characters).

void wxNotificationMessage::SetParent ( wxWindow * parent )

Set the parent for this notification: the notification will be associated with the top level parent of this window or, if this method is not called, with the main application window by default.

void wxNotificationMessage::SetTitle ( const wxString & title )

Set the title, it must be a concise string (not more than 64 characters), use SetMessage() to give the user more details.

virtual bool wxNotificationMessage::Show ( int timeout = Timeout_Auto )

virtual

Show the notification to the user and hides it after timeout seconds are elapsed.

Special values Timeout_Auto and Timeout_Never can be used here, notice that you shouldn't rely on timeout being exactly respected because the current platform may only support default timeout value and also because the user may be able to close the notification.

Note: When using native notifications in wxGTK, the timeout is ignored for the notifications with wxICON_WARNING or wxICON_ERROR flags, they always remain shown unless they're explicitly hidden by the user, i.e. behave as if Timeout_Auto were given.

Returns: false if an error occurred.
