Tkinter的改變上產生模糊文本小

Question

我試圖更改所選文本的默認背景顏色在Mac OS X 一個Tkinter的文本小部件時，窗口小部件沒有焦點選擇背景色。默認未聚焦的選擇顏色是灰色的。經過許多小時的搜索之後，我無法找到開箱即用的解決方案來執行此操作。以下是我所嘗試的：

• 使用selectbackground選項更改選擇顏色不會更改未部件的選擇顏色。例如。它保持灰色。
• 也不Text.tag_configure("sel", background=...)
• 使用ttk.Style.map與錄入組件（和其他人）的"!focus"狀態的作品，而不是文本部件。

所以我不得不推出自己的（見下文）。有一個更好的方法嗎？

import Tkinter as tk 

# Replace 'tag_out' with 'tag_in' 
def replace_tag(widget, tag_out, tag_in): 
    ranges = widget.tag_ranges(tag_out) 
    widget.tag_remove(tag_out, ranges[0], ranges[1]) 
    widget.tag_add(tag_in, ranges[0], ranges[1]) 

def focusin(e): 
    replace_tag(e.widget, "sel_focusout", "sel") 

def focusout(e): 
    replace_tag(e.widget, "sel", "sel_focusout") 


root = tk.Tk() 

# Create a Text widget with a red selected text background 
text = tk.Text(root, selectbackground="red") 
text.pack() 

# Add some text, and select it 
text.insert("1.0", "Hello, world!") 
text.tag_add("sel", "1.0", "end") 

# Create a new tag to handle changing the background color on selected text 
# when the Text widget loses focus 
text.tag_configure("sel_focusout", background="green") 
replace_tag(text, "sel", "sel_focusout") 

# Bind the events to make this magic happen 
text.bind("<FocusIn>", focusin) 
text.bind("<FocusOut>", focusout) 


# Create an Entry widget to easily test the focus behavior 
entry = tk.Entry(root) 
entry.pack() 

entry.insert("0", "Focus me!") 

root.mainloop()

挖掘Tk源代碼，讓我找到答案！ inactiveselectbackground選項設置顏色。

import Tkinter as tk 

root = tk.Tk() 

# Create a Text widget with a red selected text background 
# And green selected text background when not focused 
text = tk.Text(root, selectbackground="red", inactiveselectbackground="green") 
text.pack() 

# Add some text, and select it 
text.insert("1.0", "Hello, world!") 
text.tag_add("sel", "1.0", "end") 

# Create an Entry widget to easily test the focus behavior 
entry = tk.Entry(root) 
entry.pack() 

entry.insert("0", "Focus me!") 

root.mainloop()
