def photo_class(self): print(1) self.pushButton_6.clicked.connect(self.photo_craw) print(2) def photo_craw(self): directory = filedialog.askdirectory() if directory: print(f"Selected directory: {directory}")删去窗口

你可以直接将 `photo_craw` 函数中的内容提取出来，然后在 `photo_class` 函数中调用 `filedialog.askdirectory()` 来选择目录并处理选择结果。以下是示例代码：

from tkinter import filedialog

def photo_class(self):
    print(1)
    self.pushButton_6.clicked.connect(self.photo_craw)
    print(2)
    
def photo_craw(self):
    directory = filedialog.askdirectory()
    if directory:
        print(f"Selected directory: {directory}")
        # 在这里可以处理选择的目录

这个程序中，`photo_class` 函数没有改变，`photo_craw` 函数被删去了，而是在 `photo_class` 函数中调用了 `filedialog.askdirectory()` 来选择目录并处理选择结果。

你忘记了在导入模块时使用逗号分隔，应该改为:

        self.lineEdit.insert("-")

这段代码是用于初始化信号槽（slots）的连接。

通过调用`clicked.connect`方法，将按钮的`clicked`信号与相应的槽函数进行连接。具体来说：

- `self.pushButton_img.clicked.connect(self.load_source)`将"pushButton_img"按钮的`clicked`信号连接到`load_source`槽函数。
- `self.pushButton_model.clicked.connect(self.select_model)`将"pushButton_model"按钮的`clicked`信号连接到`select_model`槽函数。
- `self.pushButton_detect.clicked.connect(self.target_detect)`将"pushButton_detect"按钮的`clicked`信号连接到`target_detect`槽函数。
- `self.pushButton_showdir.clicked.connect(self.show_dir)`将"pushButton_showdir"按钮的`clicked`信号连接到`show_dir`槽函数。
- `self.pushButton_camera_detect.clicked.connect(self.camera_detect)`将"pushButton_camera_detect"按钮的`clicked`信号连接到`camera_detect`槽函数。

通过这些连接，当用户点击相应的按钮时，对应的槽函数将会被调用。
