选项菜单对齐问题tkinter

如何解决选项菜单对齐问题tkinter

我正在尝试在两个标签下面添加两个下拉列表，说明它们的含义。问题是每当我运行它时，第二个列表就会向左偏移。这发生在setupPage部分中，如下所示： image of the issue

我尝试了很多粘稠的组合，但都无济于事。任何帮助将不胜感激。

代码：

process.on("uncaughtException",(error: Error) => {
  (async () => {
    await this.errorHandler(error);

    // ...
  })();
});

解决方法

标签的父级和OptionMenus不同。 将父母改为root而不是内容似乎很有效

from tkinter import *
from tkinter import ttk

root = Tk()

def startPage(root):
        print("oi")
        content = ttk.Frame(root) #frame for plaing everything into
        #frame = ttk.Frame(content,borderwidth=5,relief="sunken",width=200,height=100) #fram for plaxing images
        lbl1 = ttk.Label(content,text="Is this a new or existing site?",font=("arial",12)) #setup of label for screen 1

        yesvar = BooleanVar() #variables for check boxes later on
        novar = BooleanVar()    
        yesvar.set(False)
        novar.set(False)

        one = ttk.Checkbutton(content,text="Yes",variable=yesvar,onvalue=True) #check buttons setup
        two = ttk.Checkbutton(content,text="No",variable=novar,onvalue=True)
        ok = ttk.Button(content,text="New",command = nextPage)    #setup for buttons screen 1
        cancel = ttk.Button(content,text="Existing")

        content.grid(column=0,row=0)   #intilises content 
        #frame.grid(column=0,row=0,columnspan=3,rowspan=2)
        lbl1.grid(column=0,pady=10,padx=10) #places the label asking the question with a gap either side for the window bindings
        #name.grid(column=3,row=1,columnspan=2)
        #one.grid(column=0,row=3)
        #two.grid(column=1,row=3)
        ok.grid(column=0,padx=10)     #places yes button 10 away from each edge
        cancel.grid(column=1,padx=10) #as above

def setupPage(root):
            #content = ttk.Frame(root) #frame for plaing everything into
            #frame = ttk.Frame(content,height=100) #fram for plaxing images
            lbl1 = ttk.Label(root,text="Select meterial 1",12)) #setup of label for screen 1
            lbl2 = ttk.Label(root,text = "Select meterial 2",font = ("arial",12))
            #content.grid(column=0,row=0)
            lbl1.grid(column=0,columnspan=1,padx=10)
            lbl2.grid(column=1,padx=10)
            clicked = StringVar()
            clicked.set("lo2")
            clicked2 = StringVar()
            clicked2.set("lo2")
            drop2 = OptionMenu(root,clicked2,"lo2","mo3","Lo2+mo3")
            drop = OptionMenu(root,clicked,"Lo2+mo3")
            drop.grid(column=0,padx=10,sticky=NW)
            drop2.grid(column=1,sticky=NW)

def nextPage():
        print("oi2")
        global pagenum,root
        for widget in root.winfo_children():
            widget.destroy()
        if pagenum == 1:
            print("oi3")
            setupPage(root)
            pagenum = 2
        else :
            startPage(root)
            pagenum = 1

startPage(root)
pagenum = 1
root.mainloop()
