我有一个透明的根窗口。我也有一个标签,它是根窗口的子级。我注意到标签也和根一样透明。下面是我正在使用的代码:
try:
import tkinter as tk
except ImportError:
import Tkinter as tk
root = tk.Tk()
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
def exit(event):
root.destroy()
class TestApp:
def __init__(self, parent):
self.parent = parent
self.label = tk.Label(self.parent, font=("Arial", 18, 'bold'),
width=30, fg="red")
self.label.configure(text="Test message")
self.label.pack()
if __name__ == "__main__":
testApp = TestApp(root)
root.bind("<Key>", exit)
root.geometry("%sx%s" % (screen_width, screen_height))
root.attributes('-alpha', 0.3)
root.overrideredirect(True)
root.lower()
root.wm_attributes("-topmost", True)
root.wm_attributes("-disabled", True)
root.wm_attributes("-transparentcolor", "white")
root.mainloop()
如果alpha的值是0.3(在root.attributes('-alpha',0.3)行中,则文本在屏幕上可见,但是如果值为0.0,则文本在屏幕上不可见) 。只想知道如何将root的透明度设置为0.0,并使标签文本在屏幕上可见
root.wm_attributes("-transparentcolor","white")
这将使您提供的颜色透明。如果要使root
背景透明,则可以使用root.wm_attributes("-transparentcolor", root['bg'])
。然后,无需设置root.attributes('-alpha', 0.3)
您的代码应为:
try:
import tkinter as tk
except ImportError:
import Tkinter as tk
root = tk.Tk()
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
def exit(event):
root.destroy()
class TestApp:
def __init__(self, parent):
self.parent = parent
self.label = tk.Label(self.parent, font=("Arial", 18, 'bold'),
width=30, fg="red")
self.label.configure(text="Test message")
self.label.pack()
if __name__ == "__main__":
testApp = TestApp(root)
root.bind("<Key>", exit)
root.geometry("%sx%s" % (screen_width, screen_height))
root.overrideredirect(True)
root.lower()
root.wm_attributes("-topmost", True)
root.wm_attributes("-disabled", True)
root.wm_attributes("-transparentcolor", root['bg'])
root.mainloop()
