[Pythonmac-SIG] Simple Statusitem example

[Dethe Elza]

Here is a very simple example of a statusbar item, requiring no further resources. A real statusitem would probably have a Nib to load a menu and maybe a configuration panel from, icons, etc.

================ begin statusitem.py ======================

import objc
from Foundation import *
from AppKit import *
from PyObjCTools import NibClassBuilder, AppHelper

start_time = NSDate.date()

class Timer(NSObject):
    '''
    Application delegate
    '''
    statusbar = None

def applicationDidFinishLaunching_(self, notification):
print 'timer launched'
# Make the statusbar item
statusbar = NSStatusBar.systemStatusBar()
# if you use an icon, the length can be NSSquareStatusItemLength
statusitem = statusbar.statusItemWithLength_(NSVariableStatusItemLength)
self.statusitem = statusitem # Need to retain this for later
# statusitem.setImage_(some_image)
#statusitem.setMenu_(some_menu)
statusitem.setToolTip_('Seconds since startup')
statusitem.setAction_('terminate:') # must have some way to exit
self.timer = NSTimer.alloc().initWithFireDate_interval_target_selector_userInfo_repea ts_(
start_time,
1.0,
self,
'display:',
None,
True
)
NSRunLoop.currentRunLoop().addTimer_forMode_(self.timer, NSDefaultRunLoopMode)
self.timer.fire()

    def display_(self, notification):
        print 'display:'
        self.statusitem.setTitle_(elapsed())

def elapsed():
    return str(int(NSDate.date().timeIntervalSinceDate_(start_time)))

if __name__ == "__main__":
    app = NSApplication.sharedApplication()
    delegate = Timer.alloc().init()
    app.setDelegate_(delegate)
    AppHelper.runEventLoop()

====================== end statusitem.py ================================

The main thing about the setup file is to pass LSUIElement = '1' in the plist to suppress the dock icon.
The program should perhaps hide itself as well.

====================== begin setup.py ==================================

'''
Minimal setup.py example, run with:
% python setup.py py2app
'''

from distutils.core import setup
import py2app

NAME = 'Uptime'
SCRIPT = 'statusitem.py'
VERSION = '0.1'
ID = 'uptime'

plist = dict(
    CFBundleName                = NAME,
    CFBundleShortVersionString  = ' '.join([NAME, VERSION]),
    CFBundleGetInfoString       = NAME,
    CFBundleExecutable          = NAME,
    CFBundleIdentifier          = 'org.livingcode.examples.%s' % ID,
    LSUIElement                 = '1'
)

app_data = dict(script=SCRIPT, plist=plist)

setup(
  app = [app_data],
)

====================== end setup.py ====================================
