我有这个类来创建一个状态栏:
class Statusbar(Canvas):
'''Creates a statusbar widget'''
def __init__(self, master = None, **options):
if not master: master = Tk()
self.master, self.options = master, options
self.barFill, self.addText, self.value = self.options.get('barFill', 'red'), self.options.get('addText', True), 0
for option in ('barFill', 'addText'):
if option in self.options: del self.options[option]
Canvas.__init__(self, master, **self.options)
self.offset = self.winfo_reqwidth() / 100
self.height = self.winfo_reqwidth()
if self.addText: self.text = self.create_text(self.winfo_reqwidth()/2, self.winfo_reqheight()/2, text = '0%')
self.bar = self.create_rectangle(0, 0, self.value, self.height, fill = self.barFill)
def setValue(self, value):
'''Sets the value of the status bar as a percent'''
self.value = value * self.offset
self.coords(self.bar, 0, 0, self.value, self.height)
if self.addText: self.itemconfigure(self.text, text = str(self.value/self.offset) + '%')
def change(self, value):
'''Changes the value as a percent'''
self.value += (value * self.offset)
self.coords(self.bar, 0, 0, self.value, self.height)
if self.addText: self.itemconfigure(self.text, text = str(self.value/self.offset) + '%')
我的问题是文本总是在矩形下绘制。因此,当矩形到达文本时,您将无法再看到文本。我怎样才能解决这个问题?提前致谢。
