Question

################################################
#        Left           |         Right        #
#-----------------------|----------------------#
# hello|  hello  |      | hello|  hello | hello#
#-----------------------|------|--------|------#
#                       | hello|               #

我想生成一些上面那种类型的 tkinter window。 Left 和 Right 是两个按钮。如果我点击左侧，一个新的小部件 window 打开并带有一个应用按钮。如果我点击应用程序应该记住我从哪个按钮打开 Window 和应用按钮并在左边（如果先按下左按钮）或右边（如果右按钮是先按下）。

我现在的程序是这样的：

################################################
#        Left           |         Right        #
#-----------------------|----------------------#
#       hello           |         hello        #
#-----------------------|----------------------#
#                       |         hello        #
################################################

如何将样式从第二种解决方案更改为第一种？

我的解决方案二的代码：

from tkinter import *

class NewWindow(Toplevel):
    def __init__(self, master = None, apply=None):
        super().__init__(master = master)
        self.title('NewWindow')
        self.master = master
        self.words = 'Hello'

 
        self.bt1 = Button(self, text="apply", command=self.bt_press)
        self.bt1.grid(column=0, row=0)
        self.apply = apply
    def bt_press(self):
        self.apply(self.words)
        self.destroy()

root = Tk()

def new_Editor(key):
    def make_label1(lbl_txt):
        print("root.grid_slaves(0):", root.grid_slaves(column=0))
        row = len(root.grid_slaves(column=0))+1
        lbl = Label(root, text=lbl_txt)
        lbl.grid(row=row, column=0)
    def make_label2(lbl_txt):
        print("root.grid_slaves(1):", root.grid_slaves(column=1))
        row = len(root.grid_slaves(column=1))+1
        lbl = Label(root, text=lbl_txt)
        lbl.grid(row=row, column=1)

    if key == 1:
        a = NewWindow(root, make_label1)
    else:
        a = NewWindow(root, make_label2)

root.title("BasicWindow")

root.basic_bt_l = Button(root, text="Left", command=lambda: new_Editor(1))
root.basic_bt_l.grid(column=0, row=0)


root.basic_bt_r = Button(root, text="Right", command=lambda: new_Editor(2))
root.basic_bt_r.grid(column=1, row=0)

root.mainloop()

Answer 1

我建议为标签创建两个框架，一个用于左，另一个用于右。

然后可以根据每一帧的label个数来确定要添加的新label的行和列。

from tkinter import *

class NewWindow(Toplevel):
    def __init__(self, master = None, apply=None):
        super().__init__(master = master)
        self.title('NewWindow')
        self.master = master
        self.words = 'Hello'

        self.bt1 = Button(self, text="apply", command=self.bt_press)
        self.bt1.grid(column=0, row=0)
        self.apply = apply

    def bt_press(self):
        self.apply(self.words)
        self.destroy()

root = Tk()

# adjust the below two settings to suit your requirement
COLS = 3
COLWIDTH = 50

def new_Editor(key):
    def make_label1(lbl_txt):
        # get the children of left frame
        slaves = root.left_frame.grid_slaves()
        print("root.left_frame.grid_slaves():", slaves)
        # determine the row and column of the new label
        row, col = divmod(len(slaves), COLS)
        lbl = Label(root.left_frame, text=lbl_txt)
        lbl.grid(row=row, column=col)

    def make_label2(lbl_txt):
        # get the children of right frame
        slaves = root.right_frame.grid_slaves()
        print("root.right_frame.grid_slaves():", slaves)
        # determine the row and column of the new label
        row, col = divmod(len(slaves), COLS)
        lbl = Label(root.right_frame, text=lbl_txt)
        lbl.grid(row=row, column=col)

    if key == 1:
        a = NewWindow(root, make_label1)
    else:
        a = NewWindow(root, make_label2)

root.title("BasicWindow")
# make the two column same size
root.columnconfigure((0,1), weight=1, uniform=1, minsize=COLS*COLWIDTH)

root.basic_bt_l = Button(root, text="Left", command=lambda: new_Editor(1))
root.basic_bt_l.grid(column=0, row=0)

root.basic_bt_r = Button(root, text="Right", command=lambda: new_Editor(2))
root.basic_bt_r.grid(column=1, row=0)

# frame for left labels
root.left_frame = Frame(root)
root.left_frame.grid(row=1, column=0, sticky='nsew')
# make all the columns inside the frame same size
root.left_frame.columnconfigure(list(range(COLS)), weight=1, uniform=1, minsize=COLWIDTH)

# frame for right labels
root.right_frame = Frame(root)
root.right_frame.grid(row=1, column=1, sticky='nsew')
# make all the columns inside the frame same size
root.right_frame.columnconfigure(list(range(COLS)), weight=1, uniform=1, minsize=COLWIDTH)

root.mainloop()

结果：

Python - tkinter - 在某些 window 中放置不同的网格？

Python - tkinter - put different grids in some window?
