添加占位的 Label tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True) # 添加“查询”按钮 ttk.Button(toolbar, text="查詢", style='my.TButton', command=lambda: QueryWindow(tk.Toplevel(master))).pack( side=tk.LEFT, padx=2, pady=2, anchor=tk.CENTER) # 添加占位的 Label tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True) # 添加“關閉”按钮 ttk.Button(toolbar, text="關閉", style='my.TButton', command=self.quit_app).pack(side=tk.LEFT, padx=2, pady=2, anchor=tk.CENTER) # 显示工具栏 toolbar.pack(side=tk.TOP, fill=tk.BOTH這個代碼

您可以通过将 `side` 参数设置为 `tk.LEFT` 来将占位 Label 移动到左侧，如下所示：

# 添加占位的 Label
tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True)

# 添加“查询”按钮
ttk.Button(toolbar, text="查詢", style='my.TButton', command=lambda: QueryWindow(tk.Toplevel(master))).pack(
    side=tk.LEFT, padx=2, pady=2, anchor=tk.CENTER)

# 添加占位的 Label
tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True)

# 添加“關閉”按钮
ttk.Button(toolbar, text="關閉", style='my.TButton', command=self.quit_app).pack(
    side=tk.LEFT, padx=2, pady=2, anchor=tk.CENTER)

# 显示工具栏
toolbar.pack(side=tk.TOP, fill=tk.BOTH)

这将使占位 Label 和按钮都位于工具栏的左侧。

创建工具栏 toolbar = tk.Frame(master, height=0.2) # 创建样式 style = ttk.Style() style.configure('my.TButton', font=('Arial', 10)) # 设置鼠标悬停时的颜色 style.map('my.TButton', background=[('active', 'blue')]) # 添加占位的 Label tk.Label(toolbar, text="当前选中：").pack(side=tk.LEFT, padx=0.02, pady=0.02) self.selected_label = tk.Label(toolbar, text="", fg="red", font=("Arial", 12)) self.selected_label.pack(side=tk.LEFT, padx=0.02, pady=0.02) tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True) # 添加占位的 Label tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True) # 添加“查询”按钮 ttk.Button(toolbar, text="查詢", style='my.TButton', command=lambda: QueryWindow(tk.Toplevel(master))).pack(side=tk.LEFT, padx=5, pady=5, anchor=tk.CENTER) tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True) ttk.Button(toolbar, text="關閉", style='my.TButton', command=self.quit_app).pack(side=tk.LEFT, padx=5, pady=5, anchor=tk.CENTER) # 显示工具栏 toolbar.pack(side=tk.TOP, fill=tk.BOTH)將工具欄中的兩個按鈕放到工具欄的中間

可以使用占位的 Label 来实现将两个按钮放到工具栏的中间。具体地，可以在两个按钮之间分别添加一个占位的 Label，将它们的 fill 属性设置为 BOTH，expand 属性设置为 True，这样它们就会平均地填充工具栏中两个按钮之间的空隙，从而实现将两个按钮放到工具栏的中间。代码如下：

# 添加占位的 Label
tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True)

# 添加“查询”按钮
ttk.Button(toolbar, text="查詢", style='my.TButton', command=lambda: QueryWindow(tk.Toplevel(master))).pack(side=tk.LEFT, padx=5, pady=5, anchor=tk.CENTER)

# 添加占位的 Label
tk.Label(toolbar).pack(side=tk.LEFT, fill=tk.BOTH, expand=True)

# 添加“關閉”按钮
ttk.Button(toolbar, text="關閉", style='my.TButton', command=self.quit_app).pack(side=tk.LEFT, padx=5, pady=5, anchor=tk.CENTER)

# 显示工具栏
toolbar.pack(side=tk.TOP, fill=tk.BOTH)
