Tkinter Text小部件中的超链接？ [英] Hyperlink in Tkinter Text widget?

问题描述

我正在设计当前软件项目的一部分，并希望使用超链接而不是按钮。我真的不想使用 Text 小部件，但这是我搜索主题时能找到的全部内容。无论如何，我找到了一个这样的例子，但不断收到此错误：

I am re designing a portion of my current software project, and want to use hyperlinks instead of Buttons. I really didn't want to use a Text widget, but that is all I could find when I googled the subject. Anyway, I found an example of this, but keep getting this error:

TclError: bitmap "blue" not defined

当我添加这行代码时（使用 IDLE ）

When I add this line of code (using the IDLE)

hyperlink = tkHyperlinkManager.HyperlinkManager(text)

该模块的代码位于此处以及代码该脚本位于此处

The code for the module is located here and the code for the script is located here

任何人都有任何想法？

Anyone have any ideas?

提出问题的部分是 foreground =blue，这在Tkinter中被称为颜色，不是吗？

The part that is giving problems says foreground="blue", which is known as a color in Tkinter, isn't it?

推荐答案

如果您不想使用文本小部件，则不需要。另一种方法是使用标签并将鼠标点击绑定到它。即使它是一个标签，它仍然会响应事件。

If you don't want to use a text widget, you don't need to. An alternative is to use a label and bind mouse clicks to it. Even though it's a label it still responds to events.

例如：

import tkinter as tk

class App:
    def __init__(self, root):
        self.root = root
        for text in ("link1", "link2", "link3"):
            link = tk.Label(text=text, foreground="#0000ff")
            link.bind("<1>", lambda event, text=text: self.click_link(event, text))
            link.pack()

    def click_link(self, event, text):
        print("You clicked '%s'" % text)

root = tk.Tk()
app = App(root)
root.mainloop()

如果需要，您可以为< Enter> 添加额外的绑定<离开> 事件，以便您可以在用户悬停时更改外观。当然，如果您愿意，可以更改字体以便文本加下划线。

If you want, you can get fancy and add additional bindings for <Enter> and <Leave> events so you can alter the look when the user hovers. And, of course, you can change the font so that the text is underlined if you so choose.

Tk是一个很棒的工具包，可以为您提供构建基块关于你想要什么。您只需将小部件看作一组预制的墙壁和门，但更像是一堆腰，砖和砂浆。

Tk is a wonderful toolkit that gives you the building blocks to do just about whatever you want. You just need to look at the widgets not as a set of pre-made walls and doors but more like a pile of lumbar, bricks and mortar.
