问题是它只适用于一个全局函数..如何为不同的函数分配每个按钮

from tkinter import*
class mainWindow:
    def __init__(self,master):
        mainFrame=Frame(master)
        mainFrame.pack()
        self.cv=Canvas(scrollregion=(0,0,200,1200),width=200,height=1200,bg='green')

问题是它只适用于一个全局函数..如何为不同的函数分配每个按钮

Answer 1

首先：您可以使用按钮（command = function_name）
代替绑定（＆＃39;＆lt; Button-1＆gt;＆＃39;，function_name）

创建功能列表

functions = [self.subT1, self.other_function] 

for i in range(2):
    Button(command=functions[i])


def subT1(self): # without `event` or with `event=None`

from tkinter import*
class mainWindow:
    def __init__(self,master):
        mainFrame=Frame(master)
        mainFrame.pack()
        self.cv=Canvas(scrollregion=(0,0,200,1200),width=200,height=1200,bg='green')
        self.scb=Scrollbar(command=self.cv.yview)
        self.cv.pack(side=LEFT)
        self.scb.pack(side=RIGHT,fill=Y)
        self.cv.configure(yscrollcommand=self.scb.set)

        #Frame to Canvas
        self.cvFrame=Frame(master)
        self.cvFrame_window=self.cv.create_window(5,5,anchor=NW,window=self.cvFrame)

        self.t=['Site Preparation','WBLFF','Frame','Roof Construction','Roof Finishes',]
        self.tr=[0,1,2,3,4,5]
    #range button created inside one frame
        for i in range(5):
            self.tButton=Button(self.cvFrame,text=self.t[i],bg='purple',fg='white',width=20,relief=GROOVE)
            self.tButton.grid(in_=self.cvFrame,row=self.tr[i])
            if i in range(0,1):
                self.tButton.bind('<Button-1>',self.subT1)
            if i in range(1,2):
                self.tButton.bind('<Button-1>',self.subT2)

    def subT1(self,event):
        self.s=['Site Preparation','Site Clearence','Earth Works']
        self.sc=['dark violet','yellow','yellow']
        self.sf=['white','black','black']

        self.sFrame=Frame(self.cvFrame)
        self.sFrame.grid(in_=self.cvFrame,row=0)
        for x in range(3):           
            self.sBtn=Button(self.sFrame,text=self.s[x],bg=self.sc[x],fg=self.sf[x],width=20,relief=GROOVE)
            self.sBtn.grid(in_=self.sFrame,row=x)
            self.sBtn.bind('<Button-1>',self.destF)

    def subT2(self,event):  
        self.s=['WBLFF','Pile Cap','Column Stump','Ground Beam','Ground Slab']
        self.sc=['dark violet','yellow','yellow','yellow','yellow']
        self.sf=['white','black','black','black','black']

        self.sFrame=Frame(self.cvFrame)
        self.sFrame.grid(in_=self.cvFrame,row=1)
        for x in range(5):           
            self.sBtn=Button(self.sFrame,text=self.s[x],bg=self.sc[x],fg=self.sf[x],width=20,relief=GROOVE)
            self.sBtn.grid(in_=self.sFrame,row=x)
            self.sBtn.bind('<Button-1>',self.destF)

    #detroy frame back to main title
    def destF(self,event):
        self.sFrame.destroy()

#root window
root=Tk()
root.title('Built Up Rates')
root.geometry('220x600+0+0')
A=mainWindow(root)
root.mainloop()

得到它:)通过使用'if'语句...在ranged对象中运行良好并分配参数是否有任何其他方法可以使它更简单，如继承或全局定义？

Tkinter为每个范围按钮分配不同的功能
