Tkinter顶层窗口
顶层窗口小部件用于创建和显示由窗口管理器直接管理的顶层窗口。顶层窗口小部件的顶部可能带有父窗口，也可能没有。
当Python应用程序需要在新窗口中表示一些额外的信息，弹出窗口或一组窗口小部件时，将使用顶层窗口小部件。
顶层窗口具有标题栏，边框和其他窗口装饰。
下面给出了使用“顶级”窗口小部件的语法。
句法
w = Toplevel(options)
下面列出了可能的选项。
| SN | Options | Description |
|---|---|---|
| 1 | bg | It represents the background color of the window. |
| 2 | bd | It represents the border size of the window. |
| 3 | cursor | The mouse pointer is changed to the cursor type set to the arrow, dot, etc. when the mouse is in the window. |
| 4 | class_ | The text selected in the text widget is exported to be selected to the window manager. We can set this to 0 to make this behavior false. |
| 5 | font | The font type of the text inserted into the widget. |
| 6 | fg | The foreground color of the widget. |
| 7 | height | It represents the height of the window. |
| 8 | relief | It represents the type of the window. |
| 9 | width | It represents the width of the window, |
方法
下面的列表中给出了与Toplevel小部件关联的方法。
| SN | Method | Description |
|---|---|---|
| 1 | deiconify() | This method is used to display the window. |
| 2 | frame() | It is used to show a system dependent window identifier. |
| 3 | group(window) | It is used to add this window to the specified window group. |
| 4 | iconify() | It is used to convert the toplevel window into an icon. |
| 5 | protocol(name, function) | It is used to mention a function which will be called for the specific protocol. |
| 6 | state() | It is used to get the current state of the window. Possible values are normal, iconic, withdrawn, and icon. |
| 7 | transient([master]) | It is used to convert this window to a transient window (temporary). |
| 8 | withdraw() | It is used to delete the window but doesn’t destroy it. |
| 9 | maxsize(width, height) | It is used to declare the maximum size for the window. |
| 10 | minsize(width, height) | It is used to declare the minimum size for the window. |
| 11 | positionfrom(who) | It is used to define the position controller. |
| 12 | resizable(width, height) | It is used to control whether the window can be resizable or not. |
| 13 | sizefrom(who) | It is used to define the size controller. |
| 14 | title(string) | It is used to define the title for the window. |
例
from tkinter import *
root = Tk()
root.geometry("200x200")
def open():
top = Toplevel(root)
top.mainloop()
btn = Button(root, text = "open", command = open)
btn.place(x=75,y=50)
root.mainloop()
输出：
