如何使用 tkinter 使用网格功能显示不同的图像?

问题描述

我想使用 grid() 显示文件夹中的图像.但是当我尝试使用以下代码时，我得到了单个图像迭代的输出.

I want to display the images in the folder using grid(). But when I tried with the following code, I got the output with single image iterated.

我的代码:

def messageWindow():
    win = Toplevel()
    path = 'C:UsersHPDesktopdataset'
    for r in range(7):
        for c in range(10):
            for infile in glob.glob(os.path.join(path,'*.jpg')):
              im = Image.open(infile)
              resized = im.resize((100, 100),Image.ANTIALIAS)
              tkimage = ImageTk.PhotoImage(resized)
              myvar=Label(win,image = tkimage)
              myvar.image = tkimage
              myvar.grid(row=r,column=c)   
root = Tk()
button = Button(app, text='Images in DataSet',command = messageWindow)
button.pack(padx = 1, pady = 1,anchor='ne')
button.place( x = 850, y = 60)
root.mainloop()  

当我运行这段代码时，5分钟后会弹出一个子窗口，它会显示一个像这样的图像；

When I run this code, after 5 minutes a child window will popup, and it will display a single image like this;

但是如何获取数据集中的所有图像呢?欢迎任何建议.感谢您的支持！

But how to get all the images in the dataset? Any suggestions are welcome. Tkanks for your support!

推荐答案

正如我在评论中所说，您在网格的每一行和每一列中都放置了相同的图像.以下是如何使用内置 divmod() 函数迭代计算每一行的行和列，基于 COLUMNS 的数量，您希望根据 image_count:

def messageWindow():
    win = Toplevel()
    path = r'C:UsersHPDesktopdataset'
    COLUMNS = 10
    image_count = 0
    for infile in glob.glob(os.path.join(path, '*.jpg')):
        image_count += 1
        r, c = divmod(image_count-1, COLUMNS)
        im = Image.open(infile)
        resized = im.resize((100, 100), Image.ANTIALIAS)
        tkimage = ImageTk.PhotoImage(resized)
        myvar = Label(win, image=tkimage)
        myvar.image = tkimage
        myvar.grid(row=r, column=c)
    win.mainloop()  # Not sure if you need this, too, or not...
