上面的 .retain() 用法是必需的,因为 statusItem 在从 applicationDidFinishLaunching() 方法返回时被销毁。使用 self.statusItem 将该变量绑定为 MyApplicationAppDelegate 实例中的字段。
这是一个不需要 .xib / 等的修改示例...
from Foundation import *
from AppKit import *
from PyObjCTools import AppHelper
start_time = NSDate.date()
class MyApplicationAppDelegate(NSObject):
state = 'idle'
def applicationDidFinishLaunching_(self, sender):
NSLog("Application did finish launching.")
self.statusItem = NSStatusBar.systemStatusBar().statusItemWithLength_(NSVariableStatusItemLength)
self.statusItem.setTitle_(u"Hello World")
self.statusItem.setHighlightMode_(TRUE)
self.statusItem.setEnabled_(TRUE)
# Get the timer going
self.timer = NSTimer.alloc().initWithFireDate_interval_target_selector_userInfo_repeats_(start_time, 5.0, self, 'tick:', None, True)
NSRunLoop.currentRunLoop().addTimer_forMode_(self.timer, NSDefaultRunLoopMode)
self.timer.fire()
def sync_(self, notification):
print "sync"
def tick_(self, notification):
print self.state
if __name__ == "__main__":
app = NSApplication.sharedApplication()
delegate = MyApplicationAppDelegate.alloc().init()
app.setDelegate_(delegate)
AppHelper.runEventLoop()
