【中文标题】如何将所有分类结果打印到 GUI 上的文本小部件？【英文标题】：How can I print all the classification results to the Text widget on my GUI? 【发布时间】：2021-10-31 03:13:11 【问题描述】：我有一个图形用户界面，可以将图像分类为正确或错误。如何在文本小部件中打印所有结果，以便在单击用户控制按钮后将所有结果打印出来？当我单击该按钮时，我希望在小部件中打印所有答案。但是，它只打印最后一个结果
这是我的代码

【问题讨论】：
获得该结果的原因是因为您在循环中创建Text 小部件，然后插入文本。相反，您应该将所有 Text 小部件创建移到循环之外，可能位于 initialize 方法中的某个位置，并且只保留循环中的插入。
这就是我卡住的地方！当我在循环中删除它时，我在循环之外创建了我也看不到结果！
您是否在initialize 方法中创建了文本小部件？
【参考方案1】：
您不应创建新的Text 小部件来存储每次迭代中的结果。由于您已经创建了那些 Text 小部件来显示结果和在 initialize() 中经过的时间，您可以在 for 循环之后将结果插入到这些小部件中：
def Image_Classification(self):
self.results = []
start = time.time()
for self.i in range(1, 31):
for self.j in range(1, 11):
self.filename = 'Path/Folder_'+str(self.i)+'/'+str(self.j)+'.jpg'
self.img = cv2.imread(self.filename)
self.hist = cv2.calcHist([self.img], [0], None, [256], [0,256])
self.mean_px = cv2.mean(self.img)
self.max_nums = max(self.hist); self.max_num = str(self.max_nums)
self.max_num_px = np.where(self.hist==self.max_nums)[0]+1; self.max_num_px = str(self.max_num_px)
self.min_nums = min(self.hist); self.min_num = str(self.min_nums)
self.min_num_px = np.where(self.hist==self.min_nums)[0]+1; self.min_num_px = str(self.min_num_px)
self.hist_2_num = round((self.max_nums*(2/5))[0])
self.hist_2_min_num = self.hist[self.hist>=self.hist_2_num][0]
self.hist_2_max_num = self.hist[self.hist>=self.hist_2_num][len(self.hist[self.hist>=self.hist_2_num])-1]
self.hist_2_min_val = np.where(self.hist==self.hist_2_min_num)[0][0]+1
self.hist_2_max_val = max(np.where(self.hist==self.hist[self.hist>=self.hist_2_num][len(self.hist[self.hist>=self.hist_2_num])-1])[0])
self.hist_2_diff = self.hist_2_max_val - self.hist_2_min_val
result = 'good' if self.hist_2_diff > 50 else 'bad'
self.results.append(f'self.i.self.j: result')
end = time.time()
time_elapsed = f'end-start:.3fs'
self.text3.delete('1.0', END)
self.text3.insert(END, time_elapsed)
self.text1.delete('1.0', END)
for result in self.results:
self.text1.insert(END, f'result\n')
更新：为self.text1添加滚动条：
def initialize(self):
...
self.text1 = Text(self, height=2, width=20, state=NORMAL)
self.text1.grid(column=2, row=1, sticky='nse', padx=5)
self.scrollbar1 = Scrollbar(self, orient=VERTICAL, command=self.text1.yview)
self.scrollbar1.grid(column=3, row=1, sticky='ns')
self.text1.config(yscrollcommand=self.scrollbar1.set)
...
【讨论】：
非常感谢您的帮助，有没有办法让文本小部件可滚动？请给点建议 @KimwagaMakono 您可以使用鼠标滚轮滚动文本小部件的内容。已更新答案以包含self.text1 的滚动条。
非常感谢我已经更新了它，它显示但它处于非活动状态@acw1668
@KimwagaMakono 滚动条最初应该是非活动的，因为文本框中没有内容。在单击User control 并将结果附加到文本框后，滚动条应该会变为活动状态。以上是关于如何将所有分类结果打印到 GUI 上的文本小部件？的主要内容，如果未能解决你的问题，请参考以下文章
