Tkinter标签框架

LabelFrame小部件用于在其子小部件周围绘制边框。我们还可以显示LabelFrame小部件的标题。它的作用就像一个容器，可用于对相互关联的小部件(例如单选按钮)的数量进行分组。

此小部件是Frame小部件的变体，具有框架的所有功能。它还可以显示标签。

下面给出了使用LabelFrame小部件的语法。

句法

w = LabelFrame(top, options)

选项列表如下。

SN Option Description
1 bg The background color of the widget.
2 bd It represents the size of the border shown around the indicator. The default is 2 pixels.
3 Class The default value of the class is LabelFrame.
4 colormap This option is used to specify which colomap is to be used for this widget. By colormap, we mean the 256 colors that are used to form the graphics. With this option, we can reuse the colormap of another window on this widget.
5 container If this is set to true, the LabelFrame becomes the container widget. The default value is false.
6 cursor It can be set to a cursor type, i.e. arrow, dot, etc. the mouse pointer is changed to the cursor type when it is over the widget.
7 fg It represents the foreground color of the widget.
8 font It represents the font type of the widget text.
9 height It represents the height of the widget.
10 labelAnchor It represents the exact position of the text within the widget. The default is NW(north-west)
11 labelwidget It represents the widget to be used for the label. The frame uses the text for the label if no value specified.
12 highlightbackground The color of the focus highlight border when the widget doesn’t have the focus.
13 highlightcolor The color of the focus highlight when the widget has the focus.
14 highlightthickness The width of the focus highlight border.
15 padx The horizontal padding of the widget.
16 pady The vertical padding of the widget.
17 relief It represents the border style. The default value is GROOVE.
18 text It represents the string containing the label text.

例

# !/usr/bin/python3
from tkinter import *

top = Tk()
top.geometry("300x200")

labelframe1 = LabelFrame(top, text="Positive Comments")
labelframe1.pack(fill="both", expand="yes")

toplabel = Label(labelframe1, text="Place to put the positive comments")
toplabel.pack()

labelframe2 = LabelFrame(top, text = "Negative Comments")
labelframe2.pack(fill="both", expand = "yes")

bottomlabel = Label(labelframe2,text = "Place to put the negative comments")
bottomlabel.pack()

top.mainloop()
