Functions for wxTaskBarIcon class


This class represents a taskbar icon. A taskbar icon is an icon that appears in the 'system tray' and responds to mouse clicks, optionally with a tooltip above it to help provide information.

X Window System Note

Under X Window System, the window manager must support either the "System Tray Protocol" (see http://freedesktop.org/wiki/Specifications/systemtray-spec) by freedesktop.org (WMs used by modern desktop environments such as GNOME >= 2, KDE >= 3 and XFCE >= 4 all do) or the older methods used in GNOME 1.2 and KDE 1 and 2.

If it doesn't, the icon will appear as a toplevel window on user's desktop. Because not all window managers have system tray, there's no guarantee that wxTaskBarIcon will work correctly under X Window System and so the applications should use it only as an optional component of their user interface. The user should be required to explicitly enable the taskbar icon on Unix, it shouldn't be on by default.

This class is derived (and can use functions) from: wxEvtHandler

wxWidgets docs: wxTaskBarIcon


Event types emitted from this class: taskbar_move, taskbar_left_down, taskbar_left_up, taskbar_right_down, taskbar_right_up, taskbar_left_dclick, taskbar_right_dclick

Data Types

wxTaskBarIcon() = wx:wx_object()


new(Options :: [Option]) -> wxTaskBarIcon()

Option =
   {iconType, wx:wx_enum()} |
   {createPopupMenu, fun(() -> wxMenu:wxMenu())}

Default constructor.

The iconType is only applicable on wxOSX/Cocoa.

destroy(This :: wxTaskBarIcon()) -> ok

Destroys the wxTaskBarIcon object, removing the icon if not already removed.

popupMenu(This, Menu) -> boolean()

This = wxTaskBarIcon()
Menu = wxMenu:wxMenu()

Pops up a menu at the current mouse position.

The events can be handled by a class derived from wxTaskBarIcon.

Note: It is recommended to override CreatePopupMenu() (not implemented in wx) callback instead of calling this method from event handler, because some ports (e.g. wxCocoa) may not implement popupMenu/2 and mouse click events at all.

removeIcon(This) -> boolean()

This = wxTaskBarIcon()

Removes the icon previously set with setIcon/3.

setIcon(This, Icon) -> boolean()

This = wxTaskBarIcon()
Icon = wxIcon:wxIcon()

setIcon(This, Icon, Options :: [Option]) -> boolean()

This = wxTaskBarIcon()
Icon = wxIcon:wxIcon()
Option = {tooltip, unicode:chardata()}

Sets the icon, and optional tooltip text.
