如何在python tkinter中重叠窗口小部件/框架? [英] How do you overlap widgets/frames in python tkinter?
问题描述
我想知道这是否有可能.我的目标是在较大的文本字段顶部的右下角有一个小白框.当此人在文本字段内滚动浏览文本时,白框将用作信息框".
I was wondering if this is even possible. My goal is to have a small white box in the bottom right hand corner, on top of a larger text field. The white box will be used as an "info box" while the person scrolls through the text inside of the text field.
当我说文本字段"时,是指tkinter中的文本.
When I say "text field" I mean Text from tkinter.
推荐答案
将一个小部件放置在其他小部件之上的方法是使用place
几何管理器.您可以指定相对于某些其他小部件的x/y坐标,也可以指定绝对或相对宽度和高度.
The way to place one widget on top of other widgets is to use the place
geometry manager. You can specify an x/y coordinate relative to some other widget, as well as to specify either absolute or relative widths and heights.
effbot网站在场所几何图形管理器上写得不错: http://effbot.org/tkinterbook /place.htm
The effbot site has a decent writeup on the place geometry manager: http://effbot.org/tkinterbook/place.htm
这是一个简单的例子:
import Tkinter as tk
class Example(tk.Frame):
def __init__(self, parent):
tk.Frame.__init__(self, parent)
self.text = tk.Text(self, wrap="word")
self.vsb = tk.Scrollbar(self, orient="vertical", command=self.text.yview)
self.text.configure(yscrollcommand=self.text_yview)
self.vsb.pack(side="right", fill="y")
self.text.pack(side="left", fill="both", expand=True)
# create an info window in the bottom right corner and
# inset a couple of pixels
self.info = tk.Label(self.text, width=20, borderwidth=1, relief="solid")
self.info.place(relx=1.0, rely=1.0, x=-2, y=-2,anchor="se")
def text_yview(self, *args):
'''
This gets called whenever the yview changes. For this example
we'll update the label to show the line number of the first
visible row.
'''
# first, update the scrollbar to reflect the state of the widget
self.vsb.set(*args)
# get index of first visible line, and put that in the label
index = self.text.index("@0,0")
self.info.configure(text=index)
if __name__ == "__main__":
root = tk.Tk()
Example(root).pack(side="top", fill="both", expand=True)
root.mainloop()
