Question

我正试图用一种文字来显示某些非许可特性,其行文与斜体相同。例如,我要说,“这是mytext widget”全线。

As far as I know, you can only change the font formatting of the entire widget, not individual words. I ve looked online quite a bit, but could not answer this question. I am wondering if this is possible, or if I should try a different method from using text widgets.

Answer 1

You can apply a tag to a range of characters in a text widget. Each tag can be configured with a variety of styles and a custom font. Some styles can be applied directly to the tag, some need to be applied to a font that is associated with the tag. Italics is one such style that must be applied to a font.

import tkinter as tk
from tkinter.font import Font

root = tk.Tk()

normal_font = Font(family="helvetica", size=20)
italic_font = Font(family="helvetica", size=20, slant="italic")

text = tk.Text(root, wrap="none", width=40, height=10, font=normal_font)
text.pack(fill="both", expand=True)

text.tag_configure("italics", font=italic_font)

text.insert("end", "This is ", "", "my", "italics", " text widget")

root.mainloop()

注:insert 这种方法通常用于在某一时间插入一个插图,但实际上以text、tag/em>、、>>>>>>>>>、......(最后标签可以省略)。

In the above example, we insert the whole string using a single call to insert, but notice how we apply a null tag to some parts, and the tag "italics" to the word "my". That one call to insert does exactly the same thing as these three lines, but in a more concise format:

text.insert("end", "This is ") text.insert("end", "my", "italics") text.insert("end", " text widget")

这样做的另一个方式是一劳永逸地插入整个插图,然后在一份单独声明中添加标记:

text.insert("end", "This is my text widget") text.tag_add("italics", "1.8", "1.9")

不幸的是,阴.的阴.有直接接触。工作方式可以是将案文的行文分为不同的内容,对每一条目适用不同的风格。这可能会产生类似于预期的效果。

例:

import tkinter as tk

root = tk.Tk()
root.geometry("400x100")

text_widget = tk.Text(root, wrap="none", height=1)
text_widget.pack()

text_widget.insert(tk.END, "This is ")
text_widget.tag_add("italic", "1.0", "1.4")
text_widget.tag_config("italic", font=("Times", 12, "italic"))

text_widget_italic = tk.Text(root, wrap="none", height=1)
text_widget_italic.pack()

text_widget_italic.insert(tk.END, "my")
text_widget_italic.tag_add("italic", "1.0", "1.2")
text_widget_italic.tag_config("italic", font=("Times", 12, "italic"))

text_widget.insert(tk.END, " text widget")
text_widget.tag_add("normal", "1.5", "1.end")
text_widget.tag_config("normal", font=("Times", 12))

root.mainloop()
