我很习惯使用 import tkinter as tk
import tkinter.ttk as ttk
class ProgressBarPercent(tk.Frame):
def __init__(self, parent, orient, length, mode):
tk.Frame.__init__(self, parent)
self.root = parent
# ttk style
self.style = ttk.Style()
## self.style.theme_use("clam")
self.style.configure("green.Horizontal.TProgressbar", foreground="green", background="green")
self.style.configure("blue.Horizontal.TProgressbar", foreground="blue", background="blue")
self.style.configure("yellow.Horizontal.TProgressbar", foreground="yellow", background="yellow")
self.style.configure("orange.Horizontal.TProgressbar", foreground="orange", background="orange")
self.style.configure("red.Horizontal.TProgressbar", foreground="red", background="red")
# Progressbar, percent label
self.progress = ttk.Progressbar(self, orient = orient,
length = length, mode = mode, style = "orange.Horizontal.TProgressbar")
self.text = tk.StringVar()
self.text.set("0%")
self.percent = tk.Label(self, textvariable = self.text)
self.percent.grid(column=0, row=0)
self.progress.grid(column=1, row=0)
def value(self, value):
# Progressbar updates based on input value
self.progress['value'] = value
percent_value = round(value, 1)
self.text.set(str(percent_value) + '%')
alert = False
if value < 25:
self.progress.configure(style = "green.Horizontal.TProgressbar")
elif 25 <= value < 50:
self.progress.configure(style = "blue.Horizontal.TProgressbar")
elif 50 <= value < 75:
self.progress.configure(style = "yellow.Horizontal.TProgressbar")
elif 75 <= value <= 100:
self.progress.configure(style = "orange.Horizontal.TProgressbar")
elif 100 <= value:
alert = True
self.progress.configure(style = "red.Horizontal.TProgressbar")
self.alert(alert)
def alert(self, alert):
if alert == True:
self.percent.configure(fg = 'red')
else:
self.percent.configure(fg = 'black')
if __name__ == "__main__":
root = tk.Tk()
progress = ProgressBarPercent(root, orient = tk.HORIZONTAL,
length = 100, mode = 'determinate')
progress.grid()
progress.value(67.322)
root.mainloop()
打开和关闭侧边栏。我希望侧边栏大部分时间都关闭，因为我可以通过键绑定更轻松地访问文件和功能。
但是，每次我访问当前文件夹 (cmd+b) 中的文件时，它都会在侧边栏打开的新选项卡中打开该文件。
如何防止这种行为？
我曾尝试将 cmd+t 设置为 false，但这似乎有所不同。
