NAME
wxNotificationMessage - Functions for wxNotificationMessage class
DESCRIPTION
This class allows showing the user a message non intrusively.
Currently it is implemented natively for Windows, macOS, GTK and uses generic toast
notifications under the other platforms. It's not recommended but
wxGenericNotificationMessage can be used instead of the native ones. This might make sense
if your application requires features not available in the native implementation.
Notice that this class is not a window and so doesn't derive from wxWindow.
Platform Notes
Par: Up to Windows 8 balloon notifications are displayed from an icon in the notification
area of the taskbar. If your application uses a wxTaskBarIcon you should call
useTaskBarIcon/1 to ensure that only one icon is shown in the notification area. Windows
10 displays all notifications as popup toasts. To suppress the additional icon in the
notification area on Windows 10 and for toast notification support on Windows 8 it is
recommended to call mSWUseToasts/1 before showing the first notification message.
Par: The macOS implementation uses Notification Center to display native notifications. In
order to use actions your notifications must use the alert style. This can be enabled by
the user in system settings or by setting the NSUserNotificationAlertStyle value in
Info.plist to alert. Please note that the user always has the option to change the
notification style.
Since: 2.9.0
This class is derived (and can use functions) from: wxEvtHandler

DATA TYPES
wxNotificationMessage() = wx:wx_object()
EXPORTS
new() -> wxNotificationMessage()
Default constructor, use setParent/2, setTitle/2 and setMessage/2 to initialize the
object before showing it.
new(Title) -> wxNotificationMessage()
Types:
Title = unicode:chardata()
new(Title, Options :: [Option]) -> wxNotificationMessage()
Types:
Title = unicode:chardata()
Option =
{message, unicode:chardata()} |
{parent, wxWindow:wxWindow()} |
{flags, integer()}
Create a notification object with the given attributes.
See setTitle/2, setMessage/2, setParent/2 and setFlags/2 for the description of the
corresponding parameters.
destroy(This :: wxNotificationMessage()) -> ok
Destructor does not hide the notification.
The notification can continue to be shown even after the C++ object was destroyed,
call close/1 explicitly if it needs to be hidden.
addAction(This, Actionid) -> boolean()
Types:
This = wxNotificationMessage()
Actionid = integer()
addAction(This, Actionid, Options :: [Option]) -> boolean()
Types:
This = wxNotificationMessage()
Actionid = integer()
Option = {label, unicode:chardata()}
Add an action to the notification.
If supported by the implementation this are usually buttons in the notification
selectable by the user.
Return: false if the current implementation or OS version does not support actions
in notifications.
Since: 3.1.0
close(This) -> boolean()
Types:
This = wxNotificationMessage()
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).
setFlags(This, Flags) -> ok
Types:
This = wxNotificationMessage()
Flags = integer()
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.
See: setIcon/2
setIcon(This, Icon) -> ok
Types:
This = wxNotificationMessage()
Icon = wxIcon:wxIcon()
Specify a custom icon to be displayed in the notification.
Some implementations of this class may not support custom icons.
See: setFlags/2
Since: 3.1.0
setMessage(This, Message) -> ok
Types:
This = wxNotificationMessage()
Message = unicode:chardata()
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).
setParent(This, Parent) -> ok
Types:
This = wxNotificationMessage()
Parent = wxWindow:wxWindow()
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.
setTitle(This, Title) -> ok
Types:
This = wxNotificationMessage()
Title = unicode:chardata()
Set the title, it must be a concise string (not more than 64 characters), use
setMessage/2 to give the user more details.
show(This) -> boolean()
Types:
This = wxNotificationMessage()
show(This, Options :: [Option]) -> boolean()
Types:
This = wxNotificationMessage()
Option = {timeout, integer()}
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.
Return: false if an error occurred.
useTaskBarIcon(Icon) -> wxTaskBarIcon:wxTaskBarIcon()
Types:
Icon = wxTaskBarIcon:wxTaskBarIcon()
If the application already uses a wxTaskBarIcon, it should be connected to
notifications by using this method.
This has no effect if toast notifications are used.
Return: the task bar icon which was used previously (may be NULL)
Only for:wxmsw
mSWUseToasts() -> boolean()
mSWUseToasts(Options :: [Option]) -> boolean()
Types:
Option =
{shortcutPath, unicode:chardata()} |
{appId, unicode:chardata()}
Enables toast notifications available since Windows 8 and suppresses the additional
icon in the notification area on Windows 10.
Toast notifications require a shortcut to the application in the start menu. The
start menu shortcut needs to contain an Application User Model ID. It is
recommended that the applications setup creates the shortcut and the application
specifies the setup created shortcut in shortcutPath. A call to this method will
verify (and if necessary modify) the shortcut before enabling toast notifications.
Return: false if toast notifications could not be enabled.
Only for:wxmsw
