Function Code PENGENALAN:

? ️‍?

 ?️‍? 2. 设置窗口居中

# 窗口居屏幕中央
screenwidth = root.winfo_screenwidth()
screenheight = root.winfo_screenheight()
alignstr = '%dx%d+%d+%d' % (width, height, (screenwidth-width)/2, (screenheight-height)/2)
root.geometry(alignstr)

 ?️‍? 3. 设置lable、text、button布局

font_size = 10
label1 = Label(root, text="常用正则表达式：",font=(StringVar(), font_size),pady=10)
label1.grid(row=1, column=0, sticky=W,padx=5, pady=5)

# 功能按钮
button2 = Button(root, width=15, text="测试", command=check_regex)
button3 = Button(root, width=15, text="清空所有", command=clear_all)
button2.grid(row=5, column=1, padx=5, pady=5)
button3.grid(row=5, column=2, padx=5, pady=5)

label2 = Label(root, text="正则表达式：", font=(StringVar(), font_size), pady=10)
label3 = Label(root, text="目标字符串：", font=(StringVar(), font_size), pady=10)
label4 = Label(root, text="匹配结果：", font=(StringVar(), font_size), pady=10)
label2.grid(row=2, column=0, sticky=W, padx=5)
label3.grid(row=3, column=0, sticky=W, padx=5)
label4.grid(row=4, column=0, sticky=W, padx=5)
# 设置默认项
text1 = Text(root, width=47, height=5, font=(StringVar(), font_size))
text1.insert('1.0', dic_tmp[comboxlist.get()])
text2 = Text(root, width=47, height=10, font=(StringVar(), font_size))
text3 = Text(root, width=47, height=10, font=(StringVar(), font_size))
text1.grid(row=2, column=1,columnspan=3, pady=10)
text2.grid(row=3, column=1,columnspan=3, pady=10)
text3.grid(row=4, column=1,columnspan=3, pady=10)

 ?️‍? 4. 设置下拉列表框

# 下拉选择框
def set_combox():
    comboxlist["values"] = list(dic_tmp.keys())
    comboxlist.current(0) 
    comboxlist.bind("<<ComboboxSelected>>", get_combox) 
    comboxlist.grid(row=1, column=1, pady=10)

?️‍? 5. 清空文本框

# 清空三个文本框
def clear_all():
    text1.delete('1.0', 'end')
    text2.delete('1.0', 'end')
    text3.delete('1.0', 'end')

?️‍? 6. 正则匹配结果

# 正则匹配
def check_regex():
    text3.delete('1.0', 'end') 
    re_text = text1.get('1.0', '1.end')
    source_text = text2.get('1.0', END)
    try:
        pattern = re.compile(f'{re_text}')
        result = re.findall(pattern, source_text) 
        if result:
            # 循环输出
            for res in result:
                if res != '':
                    text3.insert(END, res+'\n')
        else: 
            text3.delete('1.0', 'end')
            text3.insert('insert', '匹配结果为空')
    except:
        text3.delete('1.0', 'end')
        text3.insert('insert', '匹配失败')

?️‍? 7. 设置滚动条

# 创建滚动条
scroll2 = Scrollbar(orient=VERTICAL,command=text2.yview)
text2.config(yscrollcommand = scroll2.set)
scroll2.grid(row=3,column=4, pady=10, sticky=S+W+E+N)

# 创建滚动条
scroll3 = Scrollbar(orient=VERTICAL,command=text3.yview)
text3.config(yscrollcommand = scroll3.set)
scroll3.grid(row=4,column=4, pady=10, sticky=S+W+E+N)
