self.width = window_width什么意思

这段代码是将self对象的width属性设置为window_width变量的值。其中,self表示当前对象,width是对象的一个属性,window_width是一个变量名,它的值将被赋给self对象的width属性。这样做可以方便地在程序中使用window_width的值,而不必反复输入它的名称。

这段代码中使用了tkinter的Canvas组件来创建一个可滚动的窗口,但是在代码中并没有对Canvas绑定滚轮事件的处理程序。因此,当鼠标滚轮事件发生时,Canvas并没有响应。解决方法是在代码中使用canvas.bind()方法绑定滚轮事件,并在绑定的处理程序中调用Canvas的yview()方法来实现滚动。具体实现可以参考下面的示例代码:
```python
class Lnput_lnitialization():
def __init__(self, top, Number_of_rows):
self.top = top
int(data_demo.window_width // 3.9875)
int(data_demo.window_height // 1.138)
self.frame = tk.Frame(self.top, bg='Black', highlightthickness=2, highlightbackground='Black')
self.frame.place(relx=0.739, rely=0.083, width=int(data_demo.window_width // 3.87), height=int(data_demo.window_height // 1.15))
self.canvas = tk.Canvas(self.frame)
self.canvas.place(relx=0, rely=0, width=int(data_demo.window_width // 3.9875), height=int(data_demo.window_height // 1.15))
scrollbar = tk.Scrollbar(self.frame, command=self.canvas.yview)
scrollbar.pack(side="right", fill="y")
self.canvas.configure(yscrollcommand=scrollbar.set)
self.button_frame = tk.Frame(self.canvas, bg='Yellow')
self.button_frame.pack_propagate(False) # 禁止自动调整大小
self.button_frame.pack(fill=BOTH, expand=True) # 使其自适应大小
self.canvas.create_window((0, 0), window=self.button_frame, anchor="nw")
self.button_frame.columnconfigure(0, weight=1)
self.button_frame.columnconfigure(1, weight=1)
self.button_frame.columnconfigure(2, weight=1)
self.button_frame.columnconfigure(3, weight=1)
self.button_frame.columnconfigure(4, weight=1)
self.button_frame.columnconfigure(5, weight=1)
self.Content(Number_of_rows)
self.canvas.bind("<MouseWheel>", self.on_mousewheel)
def on_mousewheel(self, event):
self.canvas.yview_scroll(-1 * int(event.delta / 120), "units")
```
怎么将text组件换成text文件 def show_diary(self): # 创建新窗口 self.show_window = tk.Toplevel(self.master) self.show_window.title("记事本内容") # 设置子窗口大小为300x300,并让窗口居中显示 window_width = 300 window_height = 300 screen_width = self.show_window.winfo_screenwidth() screen_height = self.show_window.winfo_screenheight() x_coordinate = int((screen_width - window_width) / 2) y_coordinate = int((screen_height - window_height) / 2) self.show_window.geometry(f"{window_width}x{window_height}+{x_coordinate}+{y_coordinate}") # 创建 Text 组件 text_widget = tk.Text(self.show_window) text_widget.pack(fill='both', expand=True) # 添加日记内容到 Text 组件中 for i, entry in enumerate(diary): entry_with_number = f"{i + 1}. {entry}" text_widget.insert(tk.END, entry_with_number + '\n\n')
你可以使用Python的文件操作来打开并读取文本文件的内容,然后将其添加到Text组件中。以下是示例代码:
```python
def show_diary(self):
# 创建新窗口
self.show_window = tk.Toplevel(self.master)
self.show_window.title("记事本内容")
# 设置子窗口大小为300x300,并让窗口居中显示
window_width = 300
window_height = 300
screen_width = self.show_window.winfo_screenwidth()
screen_height = self.show_window.winfo_screenheight()
x_coordinate = int((screen_width - window_width) / 2)
y_coordinate = int((screen_height - window_height) / 2)
self.show_window.geometry(f"{window_width}x{window_height}+{x_coordinate}+{y_coordinate}")
# 创建 Text 组件
text_widget = tk.Text(self.show_window)
text_widget.pack(fill='both', expand=True)
# 读取文本文件内容并添加到 Text 组件中
with open('diary.txt', 'r') as f:
diary = f.readlines()
for i, entry in enumerate(diary):
entry_with_number = f"{i + 1}. {entry}"
text_widget.insert(tk.END, entry_with_number + '\n\n')
```
在这个示例中,我们使用了Python的`open()`函数来打开名为'diary.txt'的文本文件,并使用`readlines()`方法将其内容读取到一个列表中。然后,我们使用for循环将每个条目添加到Text组件中。
