Tkinter scrollbar语言 - - Python 3

Question

我最近一直在开发一个查询应用程序，现在我已经开始制作GUI了。我想做它，这样我就可以有一个水平滚动的滚动条，而如果GUI长度大于某个长度，垂直滚动条就会出现。唉，我只是一个Tkinter的初学者，无法理解滚动条请帮帮我。这是GUI的代码：

def run(self):
self.root1 = tk.Tk()
self.root1.protocol("WM_DELETE_WINDOW", self.cont)
self.root1.resizable(False, False)
self.root1.title(TITLE)
QAS_SEQUENCED = qasSequenced
ANSWERS = list(QAS_SEQUENCED.values())
QUESTIONS = list(QAS_SEQUENCED.keys())
print(QUESTIONS)
print(ANSWERS)
global ANSWER_FIELDS
ANSWER_FIELDS = []
ANSWER_FIELDS.clear()
self.REPLIES_AA = []
qColumnIndex = 1 #Current Column (Qs relative)
qColumnIndex_ALIGN = 1
numColumns = int(len(QUESTIONS)/10) #Num columns (Qs total)
ROW = 0
QUESTION = ""
for i in range(0, len(QUESTIONS)):
QUESTION_TMP = QUESTIONS[i]
QUESTION = ""
QUESTION_NEWLINE_INDEX = int(len(QUESTION_TMP)/40)
QUESTION_NEWLINE_INDEX_USE = 1
for ii in range(0, len(QUESTION_TMP)):
QUESTION_TMP = str(QUESTION_TMP)
if (ii+1) >= 40*QUESTION_NEWLINE_INDEX_USE or QUESTION_TMP[ii] == "`":
QUESTION += ("n")
if not QUESTION_TMP[ii] == "`":
QUESTION += str(QUESTION_TMP[ii])
QUESTION_NEWLINE_INDEX_USE += 1
else:
QUESTION += str(QUESTION_TMP[ii])
QUESTION = str(QUESTION)
ANSWERS[i] = str(ANSWERS[i])
print('Setting up question ' + str(i+1))
print('Question: ' + QUESTION + ' Answer: ' + ANSWERS[i] + "n")
if ROW > 10:
qColumnIndex += 1
qColumnIndex_ALIGN += 2
ROW = 0
QUESTION_TMP = tk.Label(self.root1)
QUESTION_TMP.config(text=QUESTION)
QUESTION_TMP.grid(row=ROW,column=(qColumnIndex_ALIGN-1))
ANSWER_TEMP_ASF = tk.Entry(self.root1)
ANSWER_TEMP_ASF.grid(row=ROW,column=(qColumnIndex_ALIGN))
ANSWER_FIELDS.append(ANSWER_TEMP_ASF)
ROW += 1
if len(QUESTIONS) <= 10:
self.submitButton = tk.Button(self.root1,text='SUBMIT ANSWERS',command=self.submitClick)
self.submitButton.grid(row=(len(QUESTIONS)+1),column=1)
else:
self.submitButton = tk.Button(self.root1, text='SUBMIT ANSWERS', command=self.submitClick)
self.submitButton.grid(row=(len(QUESTIONS)+1),column=1)
self.root1.mainloop()

Read向Tkinter-@stovfl 中的一组小部件添加滚动条

我阅读了上面提到的文章，并对我的代码进行了一些简单的更改。它们如下所示：

def onFrameConfigure(self, canvas):
'''Reset the scroll region to encompass the inner frame'''
self.canvas.configure(scrollregion=self.canvas.bbox("all"))
def run(self):
self.root1 = tk.Tk()
self.root1.protocol("WM_DELETE_WINDOW", self.cont)
self.root1.resizable(True, True)
self.root1.title(TITLE)
self.canvas = tk.Canvas(self.root1, borderwidth=0)
self.frame = tk.Frame(self.canvas)
self.vsb = tk.Scrollbar(self.root1, orient="vertical", command=self.canvas.yview)
self.xsb = tk.Scrollbar(self.root1, orient="horizontal",command=self.canvas.xview)
self.canvas.configure(yscrollcommand=self.vsb.set,xscrollcommand=self.xsb.set)
self.vsb.pack(side="right", fill="y")
self.xsb.pack(side="bottom",fill="x")
self.canvas.pack(side="left", fill="both", expand=True)
self.canvas.create_window((6,6),window=self.frame, anchor="nw")
self.frame.bind("<Configure>", lambda event, canvas=self.canvas: self.onFrameConfigure(self.canvas))
QAS_SEQUENCED = qasSequenced
ANSWERS = list(QAS_SEQUENCED.values())
QUESTIONS = list(QAS_SEQUENCED.keys())
print('SETUP Frame')
print(QUESTIONS)
print(ANSWERS)
global ANSWER_FIELDS
ANSWER_FIELDS = []
ANSWER_FIELDS.clear()
self.REPLIES_AA = []
print('Set self.REPLIES_AA')
qColumnIndex = 1 #Current Column (Qs relative)
qColumnIndex_ALIGN = 1
numColumns = int(len(QUESTIONS)/10) #Num columns (Qs total)
ROW = 0
QUESTION = ""
for i in range(0, len(QUESTIONS)):
QUESTION_TMP = QUESTIONS[i]
QUESTION = ""
QUESTION_NEWLINE_INDEX = int(len(QUESTION_TMP)/40)
QUESTION_NEWLINE_INDEX_USE = 1
for ii in range(0, len(QUESTION_TMP)):
QUESTION_TMP = str(QUESTION_TMP)
if (ii+1) >= 40*QUESTION_NEWLINE_INDEX_USE or QUESTION_TMP[ii] == "`":
QUESTION += ("n")
if not QUESTION_TMP[ii] == "`":
QUESTION += str(QUESTION_TMP[ii])
QUESTION_NEWLINE_INDEX_USE += 1
else:
QUESTION += str(QUESTION_TMP[ii])
QUESTION = str(QUESTION)
ANSWERS[i] = str(ANSWERS[i])
print('Setting up question ' + str(i+1))
print('Question: ' + QUESTION + ' Answer: ' + ANSWERS[i] + "n")
if ROW > 10:
qColumnIndex += 1
qColumnIndex_ALIGN += 2
ROW = 0
QUESTION_TMP = tk.Label(self.frame)
QUESTION_TMP.config(text=QUESTION)
QUESTION_TMP.grid(row=ROW,column=(qColumnIndex_ALIGN-1))
ANSWER_TEMP_ASF = tk.Entry(self.frame)
ANSWER_TEMP_ASF.grid(row=ROW,column=(qColumnIndex_ALIGN))
ANSWER_FIELDS.append(ANSWER_TEMP_ASF)
ROW += 1
if len(QUESTIONS) <= 10:
self.submitButton = tk.Button(self.frame,text='SUBMIT ANSWERS',command=self.submitClick)
self.submitButton.grid(row=(len(QUESTIONS)+1),column=1)
else:
self.submitButton = tk.Button(self.frame, text='SUBMIT ANSWERS', command=self.submitClick)
self.submitButton.grid(row=(len(QUESTIONS)+1),column=1)
self.root1.mainloop()

这些修改正是我想要的，现在我真的很高兴这个GUI的结果！

感谢所有的回应和帮助。
