Development builds

Building

1. Install the right compiler for your Python version. For example:
   • For Python 2.7, install Microsoft Visual C++ Compiler for Python 2.7.
   • For Python 3.5, install Visual Studio Community 2015.
2. Install Cython (pip install Cython works).
3. setup.py build_ext

You'll get a .pyd file somewhere in the build directory.

Runtime dependencies

winmmtaskbar depends on GTK+ 3 to create the button icons, but it's pretty easy to modify the code to use other ways of creating these icons. Patches to make this more general are welcome.

Usage

Assume you have a PLAYER variable containing a media player with a few media-playery methods, a GObject-like signal system, and a hwnd attribute storing the main window handle. :

import winmmtaskbar

def on_taskbar_button_clicked(button, player):
    if button == 0:
        player.prev()
    elif button == 1:
        player.playpause()
    else:
        player.next()

winmmtaskbar.create_buttons(PLAYER.hwnd,
    u"Previous", u"Play", u"Pause", u"Next",
    on_taskbar_button_clicked, PLAYER)

PLAYER.connect('state-change', lambda is_playing:
    winmmtaskbar.set_playing(PLAYER.hwnd, is_playing))

The Windows API (ITaskbarList3) does not allow adding or removing taskbar buttons once they are set.
