当禁用并重新启用状态时,我是否可以删除条目窗口小部件中的用户输入?用户输入保持原样,我希望它不需要添加按钮事件。
from Tkinter import *
class Interface():
def __init__(self, window):
frame = Frame(window)
frame.pack()
self.hopLabel = Label(frame, text="Number:", anchor=E)
self.hopLabel.grid(row=0, column=0, sticky=EW)
options = range(0,6)
options.append("Other")
self.variable = StringVar(frame)
self.variable.set(options[0])
self.options = OptionMenu(frame, self.variable, *options, command=self.this)
self.options.grid(row=0, column=2, sticky=EW)
self.button = Button(frame,text = "Print Value",width=20,command = self.printit(self.variable.get()))
self.button.grid(row=1)
self.otherEntry = Entry(frame, state=DISABLED)
self.otherEntry.grid(row=0, column=1, sticky=EW)
def this(self, value):
if value == "Other":
self.otherEntry.config(state=NORMAL)
else:
self.otherEntry.config(state=DISABLED)
def printit(self,value):
print value
if __name__ == "__main__":
root = Tk()
app = Interface(root)
root.mainloop()
为了节省空间,我没有添加打印"其他"的值的功能。选项。我的问题是:当小部件的状态从DISABLED变为NORMAL而不必按下按钮时,是否还要删除输入框中的值?
答案 0 :(得分:0)
要在禁用状态时删除条目窗口小部件中的文本,您只需先将状态设置为正常,然后调用delete
方法:
def this(self, value):
if value == "Other":
self.otherEntry.config(state=NORMAL)
self.otherEntry.delete(0, "end")
...
