Python：单击输入框时隐藏/删除标签

Question

当我点击输入框时，我试图隐藏用 Canvas 制作的标签

不是在我写的时候，而是在点击时 我该如何继续？

提前致谢

import tkinter as tk

def handle_click():

    mainCanvas.itemconfig(1, state='hidden')


window = tk.Tk()
window.geometry("500x300")
window.title("window")
mainCanvas = tk.Canvas(window, width = 500, height = 300)
mainCanvas.pack(fill = "both", expand = True)


text_input_name = tk.Entry(window, width = 25)
text_input_name_canvas = mainCanvas.create_window(250, 100, window = text_input_name)
text_input_name.bind("<1>", handle_click)

mainCanvas.create_text(250, 200, text="text", font=("Helvetica", 18), fill="red")


if __name__ == "__main__":
    window.mainloop()

您已经有了解决方案。您需要传递文本的tag/id，而不是传递1。如果要删除，请使用canvas.delete(tag_or_id)

这是一个例子。

import tkinter as tk

def handle_click(event):

    mainCanvas.itemconfig(text, state='hidden')
    #mainCanvas.delete(text)


window = tk.Tk()
window.geometry("500x300")
window.title("window")
mainCanvas = tk.Canvas(window, width = 500, height = 300)
mainCanvas.pack(fill = "both", expand = True)


text_input_name = tk.Entry(window, width = 25)
text_input_name_canvas = mainCanvas.create_window(250, 100, window = text_input_name)
text_input_name.bind("<1>", handle_click)

text = mainCanvas.create_text(250, 200, text="text", font=("Helvetica", 18), fill="red")


if __name__ == "__main__":
    window.mainloop()
