这些问题的答案:How to pass arguments to a Button command in Tkinter?和 Why is Button parameter “command” executed when declared?非常感谢。
但是，当我将按钮绑定(bind)为按下Enter键时自动执行，它立即执行。我的代码是:
from Tkinter import *
import ttk
from timeAttendance_show_DTR_GUI import *
def employee_toShow(leftFrame,rightFrame):
empNumberToShow = '1'
beginDateToShow = '2014-06-01'
endDateToShow = '2014-06-31'
requiredReport='dtr'
emp = IntVar() #please don't mind yet other parts as I am still working on them bit by bit.
ttk.Label(leftFrame, text='Enter Employee Number').pack()
emp_entry = ttk.Entry(leftFrame, textvariable=emp)
emp_entry.pack()
emp_DTR = ttk.Button(leftFrame, text='Calculate', command=lambda: indiv_DTR(rightFrame, empNumberToShow, beginDateToShow, endDateToShow, requiredReport))
emp_entry.focus()
emp_DTR.pack()
root.bind('<Return>', indiv_DTR(rightFrame, empNumberToShow, \
beginDateToShow, endDateToShow, requiredReport)) # This is where i get the problem
def indiv_DTR(frame, empNumberToShow, beginDateToShow, endDateToShow, requiredReport):
dtr, absent, frequencyOfLate, frequencyOfUndertime, totalMinutesLate, totalMinutesUndertime, \
frequencyOfGracePeriod, gracePeriodTotal = initialization(empNumberToShow, beginDateToShow, endDateToShow, requiredReport)
tree = ttk.Treeview(frame, height=31)
tree['show'] = 'headings'
tree["columns"]=('Date', 'Day', 'AmIn', 'AM Out', 'PM In', 'PM Out', 'OT In', 'OT Out', 'Late', 'Early Out', 'Remarks')
tree.column('Date', width=60)
tree.column('Day', width=45 )
tree.column('AmIn', width=50)
tree.column('AM Out', width=50)
tree.column('PM In', width=50)
tree.column('PM Out', width=50)
tree.column('OT In', width=50)
tree.column('OT Out', width=50)
tree.column('Late', width=50)
tree.column('Early Out', width=65)
tree.column('Remarks', width = 95)
tree.heading('Date', text='Date')
tree.heading("Day", text="Day")
tree.heading("AmIn", text="AM In")
tree.heading('AM Out', text='AM Out')
tree.heading('PM In', text = 'PM In')
tree.heading('PM Out', text = 'PM Out')
tree.heading('OT In', text = 'OT In')
tree.heading('OT Out', text='OT Out')
tree.heading('Late', text='Late')
tree.heading('Early Out', text='Early Out')
tree.heading('Remarks', text='Remarks')
for i in dtr:
tree.insert("" , 'end', text= '', \
values=(i[0],i[1],i[2],i[3],i[4],i[5],i[6],i[7],i[8],i[9], i[10]))
tree.pack()
if __name__ == '__main__':
employee_toShow(leftFrame,rightFrame)
root.mainloop()
显然，这里只是一个新手(甚至不确定我的代码是否缩进正确)......非常感谢任何帮助。
