In the development of interface programs with tkinter, it is often necessary to display information on the interface to give users timely feedback and desired results. The Text control allows users to display and edit text with different styles and attributes. It can contain plain text or formatted text, and supports embedded pictures, display hyperlinks, and HTML with CSS formatting.

1: Overall interface

Components used in it:

1, Radiobutton control:, radio button,

2, Text control: text box, display information

3. Scrollbar control: scroll bar

4. Button control: button

Two: overall code framework

def main(self):
        lb = Label(root, text='可视化工具', \
                #bg='#d3fbfb', \
                fg='olive', \
                font=('华文新魏', 12), \
                width=50, \
                height=2, \
                relief=FLAT)
        lb.place(relx=0.25, rely=0.01)

        var = IntVar()
        var.set(2)
        rd1 = Radiobutton(root, text="func 1", fg='red',variable=var, value=0, command=lambda: self.showResult(var.get()))
        rd1.place(relx = 0.23,rely = 0.2)
        rd2 = Radiobutton(root, text="func 2", fg='blue',variable=var, value=1,command=lambda: self.showResult(var.get()))
        rd2.place(relx = 0.4,rely = 0.2)
        rd3 = Radiobutton(root, text="func 3", fg='green',variable=var, value=2,command=lambda: self.showResult(var.get()))
        rd3.place(relx = 0.57,rely = 0.2)

        rd4 = Radiobutton(root, text="func 4", fg='DeepPink',variable=var, value=3, command=lambda: self.showResult(var.get()))
        rd4.place(relx = 0.23,rely = 0.25)
        rd5 = Radiobutton(root, text="func 5", fg='SlateBlue',variable=var, value=4,command=lambda: self.showResult(var.get()))
        rd5.place(relx = 0.4,rely = 0.25)
        rd6 = Radiobutton(root, text="func 6", fg='Brown',variable=var, value=5,command=lambda: self.showResult(var.get()))
        rd6.place(relx = 0.57,rely = 0.25)

        startButton = Button(root, text='Start',font=('华文新魏', 20),  activebackground = "green", command=lambda: self.startFunc(var.get()))
        startButton.place(relx=0.35, rely=0.89, relwidth=0.3, relheight=0.1)

Click the start button to display information in the Text control, and the Text control is bound to the scroll bar

def startFunc(self,selectFunc):
        self.collectInfo = [1,2,3,4,5,6]
        if not self.collectInfo:
            return
        if self.startButtonFirst == 0:
            self.validInfo = Text(root, width=100, height=19)#, undo=True, autoseparators=False
            self.validInfo.place(relx=0.01, rely=0.32)
            # 放到窗口的右侧, 填充Y竖直方向
            self.scroll = Scrollbar()
            self.scroll.pack(side=RIGHT,fill=Y)
            # 两个控件关联
            self.scroll.config(command=self.validInfo.yview)
            self.validInfo.config(yscrollcommand=self.scroll.set)
        self.validInfo.delete('1.0','end')
        if selectFunc == 0:
            self.validInfo.insert(INSERT, )
        elif selectFunc == 1:
            self.validInfo.insert(INSERT, self.collectInfo[1])
        elif selectFunc == 2:
            self.validInfo.insert(INSERT, self.collectInfo[2])
        elif selectFunc == 3:
            self.validInfo.insert(INSERT, self.collectInfo[3])
        elif selectFunc == 4:
            self.validInfo.insert(INSERT, self.collectInfo[4])
        elif selectFunc == 5:
            self.validInfo.insert(INSERT, self.collectInfo[5])
        self.startButtonFirst = 1

Click the radio button to display information

def showResult(self,selectFunc):
        if self.startButtonFirst == 0:
            return
        self.validInfo.delete('1.0','end')
        if selectFunc == 0:
            self.validInfo.insert(INSERT, self.collectInfo[0])
        elif selectFunc == 1:
            self.validInfo.insert(INSERT, self.collectInfo[1])
        elif selectFunc == 2:
            self.validInfo.insert(INSERT, self.collectInfo[2])
        elif selectFunc == 3:
            self.validInfo.insert(INSERT, self.collectInfo[3])
        elif selectFunc == 4:
            self.validInfo.insert(INSERT, self.collectInfo[4])
        elif selectFunc == 5:
            self.validInfo.insert(INSERT, self.collectInfo[5])

Three: Text control

1. Basic attributes

Attributes	illustrate
autoseparator	The default is True, indicating whether to automatically insert a "delimiter" when performing an undo operation (its role is to separate operation records)
exportselection	The default value is True, which means whether the selected text can be copied to the clipboard, if it is False, it means not allowed.
insertbackground	Set the color of the insertion cursor, the default is BLACK
insertborderwidth	Set the border width of the insertion cursor, the default value is 0
insertofftime	This option controls the blinking frequency of the cursor (off state)
insertontime	This option controls the blinking frequency of the cursor (light state)
selectbackground	Specify the background color of the selected text, the default is determined by the system
selectborderwidth	Specifies the background color of the selected text, the default value is 0
selectforeground	Specify the font color of the selected text, the default value is specified by the system
setgrid	The default value is False, specify a Boolean value to determine whether to enable grid control
spacing1	Specify the blank space between each line and the top of the Text control text block, pay attention to ignore automatic line break, and the default value is 0.
spacing2	Specifies the blank interval between lines in the text block of the Text control, ignoring line breaks, the default value is 0
spacing3	Specifies the blank space between each line and the bottom of the text of the Text component, ignoring automatic line wrapping, the default value is 0
tabs	Customize the function of the Tab button in the text block described by Tag, which is defined as a width of 8 characters by default. For example, tabs=('1c', '2c', '8c') means that the width of the first 3 Tabs is 1 cm, 2 cm, 8 cm.
undo	This parameter defaults to False, which means that the "undo" function of the Text control is turned off, and if it is True, it means that it is turned on
wrap	This parameter is used to set whether to automatically wrap when the length of a line of text exceeds the width set by the width option. The parameter value is none (no automatic line wrap), char (automatically wrap by character), word (automatically wrap by word)
xscrollcommand	This parameter is associated with the Scrollbar, which means sliding up and down in the horizontal direction
yscrollcommand	This parameter is associated with the Scrollbar, which means sliding left and right in the vertical direction

2. Basic method

method	illustrate
bbox(index)	Returns the bounding box of the character at the specified index, the return value is a 4-tuple in the format of (x,y,width,height)
edit_modified()	This method is used to query and set the modified flag (this flag is used to track whether the content of the Text component has changed)
edit_redo()	"Redo" the last "undo" operation, if the undo option is set to False, this method is invalid.
edit_separator()	Insert a "separator" into the stack storing operation records, which is used to indicate that a complete operation has been completed. If the undo option is set to False, this method is invalid.
get(index1, index2)	Returns the character at a specific position, or a range of literals.
image_cget(index, option)	Returns the value of the option option embedded in the image object specified by the index parameter, and throws a TclError exception if there is no embedded image object at the given position
image_create()	Embed an image object at the position specified by the index parameter, and the image object must be a PhotoImage or BitmapImage instance of Tkinter.
insert(index, text)	Insert a string at the position specified by the index parameter. The first parameter can also be set to INSERT, which means insert at the cursor, and END means insert at the end.
delete(startindex [, endindex])	Delete characters at a specific position, or a range of text.
see(index)	Returns True if the text at the specified index is visible, otherwise returns False.
