定制和创建主题和样式

• 设置样式

  style = ttk.Style()

• 设置所有部件的外观

  # 'winnative', 'clam', 'alt', 'default', 'classic', 'vista', 'xpnative'
  style.theme_use("default")

• 设置样式的新选项值

  style.configure(
    style_name + '.Heading',
    foreground=foreground,
    background=background,
    borderwidth=borderwidth,
  )

• 设置样式元素的动态行

  # active - 鼠标是否正在部件上方
  # pressed - 部件是否正被点击
  # !focus - 非聚焦中
  style.map(
    style_name + '.Heading', 
    background=[('pressed', '!focus', background), ('active', foreground),],
    foreground=[('pressed', '!focus', foreground), ('active', background),],
  )

Demo Code

import tkinter.ttk as ttk


root = tk.Tk()
root.title('Table')

columns = [str(i+1) for i in range(10)]
table = ttk.Treeview(root, columns=columns, show='headings')
table.pack()

font = ('Courier New', 20)
# extra one space reserved for each column
width = tkfont.Font(font=font).measure('000')
for column in columns:
    table.heading(column=column, text=column)
    table.column(column, width=width, anchor='center', stretch=tk.NO)

# Set color of headings
white, blue, green = 'white', 'blue', 'green'
style = ttk.Style()

# Better with extra one space for each column when setting
# 'winnative', 'clam', 'alt', 'default', 'classic', 'vista', 'xpnative'
style.theme_use('winnative')

style_name = 'Treeview'
style.configure(
    style_name + '.Heading',
    foreground=white,
    background=blue,
    borderwidth=1,
    font=font,
)
