Question

这是我的第一篇文章，我仍然是python世界的新手。我试图用python / tkinter创建一个GUI应用程序，我遇到了一些麻烦。我有2个图像文件夹，我需要显示一个带有一些文本的页面，然后显示文件夹A中的图像，然后显示带有文本的同一页面，然后显示文件夹B中的图像。我可以将这些图像显示出来起来，但我的问题是保持一切中心，看起来很好。如果我调整小于父框架的图像大小，则边缘周围会有空白。由于窗口小部件的小小，页面边缘周围有极端的空白区域。

以下列出了我遇到的问题：

小于父框架的小部件边缘周围的空白。
窗口小部件不在页面中间。

以下是我对这些问题的框架所拥有的代码。我知道这不是最干净的，但如果可能的话，我真的很感激帮助。

class TrialPage(tk.Frame):
def __init__(self, parent,controller):
    tk.Frame.__init__(self, parent)
    self.controller = controller
    self.parent = parent
    self.configure(bg='#5B9BD5')
    self.stimFrames = []
    self.evalList = []

    #initialize object to retrieve image paths
    self.trialData = TrialData()

    self.trialStim = [self.trialData.Trial_Stimuli_1,
                        self.trialData.Trial_Stimuli_2,
                        self.trialData.Trial_Stimuli_3,
                        self.trialData.Trial_Stimuli_4,
                        self.trialData.Trial_Stimuli_5,

    self.grid_rowconfigure(2,weight=1)

    self.show_break()

    #cycle through the images and show them
    img_object = next(self.pictures)
    #display image
    self.picture_display.config(image=img_object)
    #wait 2 seconds and display break page
    self.after(2000, self.show_break)
