通过 self 值更改 tkinter 中按钮的状态

Question

我有一个类 GUI 创建一个带有几个小部件的 tk 窗口 我希望保存按钮的状态根据一些自我的值而改变

在def init里面：

btn_save['state']='disabled'
if self.basepath and (self.variable.get() == 0 or self.variable.get() =='1) and (self.secondOpt.get() == '0 or self.secondOpt.get() == 1):
        btn_save['state']='normal' #here I want to change the save button state

主程序：

window = Tk()
my_gui = GUI(window)
window.mainloop()

我该怎么做？

Answer 1

使用after方法如下：

def state_change():
'''your code here'''
if self.basepath and (self.variable.get() == 0 or self.variable.get() =='1) and (self.secondOpt.get() == '0 or self.secondOpt.get() == 1):
    btn_save['state']='normal' #here I want to change the save button state
    root.after(100, state_change) #if you want to keep changing the state of the button
root.after(100, state_change)

或

使用Button 小部件专门更改它（您不需要的东西）
