Entry设置文本框内容
为什么Entry的初始文本不是aaa呢？如下：class Application_ui(Frame):#这个类仅实现界面生成功能，具体事件处理代码在子类Application中。
def __init__(self, master=None):
Frame.__init__(self, master)
self.master.title('新增')
self.master.geometry('865x525')
self.master.resizable(0,0)
self.createWidgets()
def createWidgets(self):
self.top = self.winfo_toplevel()
self.style = Style()
if opn == 2: # True
self.inportVar = StringVar(value='aaa')
else:
self.inportVar = StringVar(value='')
self.inport = Entry(self.top, textvariable=self.inportVar, font=('宋体',9))
self.inport.place(relx=0.675, rely=0.061, relwidth=0.112, relheight=0.048)
试试是不是opn == 2为false先 灰晨 发表于 2021-7-13 15:50
试试是不是opn == 2为false先
这个是True 你这类里没看见那有定义opn啊，应该是别的地方定义的吧，你只发这段我也看不出啦{:10_258:}
StringVar()我不知道能不能像你那么用
不过我都是
self.inportVar = StringVar()
self.inportVar.set('aaa')
自己试试先 我简单测试了一下这段代码，只要前面加个opn=2就能正常运行，应该是条件不符合的原因
from tkinter import *
class Application_ui(Frame):
#这个类仅实现界面生成功能，具体事件处理代码在子类Application中。
def __init__(self, master=None):
Frame.__init__(self, master)
self.master.title('新增')
self.master.geometry('865x525')
self.master.resizable(0,0)
self.createWidgets()
def createWidgets(self):
self.top = self.winfo_toplevel()
#self.style = Style()
opn = 2
if opn == 2: # True
self.inportVar = StringVar(value='aaa')
else:
self.inportVar = StringVar(value='')
self.inport = Entry(self.top, textvariable=self.inportVar, font=('宋体',9))
self.inport.place(relx=0.675, rely=0.061, relwidth=0.112, relheight=0.048)
if __name__ == '__main__':
Application_ui()
