[英]Click-through tkinter windows
function 從Tying 復制以設置與 TkInter 的不可交互(點擊)覆蓋
window 不僅不能點擊,而且 png 也不透明。 PNG在這里: https://drive.google.com/file/d/1tlLl2hjPq38mc_c_PpMhkKDlP1HqvDY5/view
這就是 window 的樣子:
我錯過了什么?
from tkinter import*
import win32gui
from win32gui import GetForegroundWindow, ShowWindow, FindWindow, SetWindowLong, GetWindowLong, SetLayeredWindowAttributes
from win32con import SW_MINIMIZE, WS_EX_LAYERED, WS_EX_TRANSPARENT, GWL_EXSTYLE
def setClickthrough(hwnd):
try:
styles = GetWindowLong(hwnd, GWL_EXSTYLE)
styles |= WS_EX_LAYERED | WS_EX_TRANSPARENT
SetWindowLong(hwnd, GWL_EXSTYLE, styles)
SetLayeredWindowAttributes(hwnd, 0, 255, win32con.LWA_ALPHA)
except Exception as e:
print(e)
root = Tk()
root.geometry("100x100")
root.overrideredirect(1)
root.attributes('-topmost', 1)
pic = PhotoImage(file=r'on2.png')
root.wm_attributes("-transparentcolor", 'white')
boardbutton = Label(root, image=pic, bd=0,
bg='white')
boardbutton.pack()
setClickthrough(root.winfo_id())
root.mainloop()
我已經獲取了鏈接問題的代碼並使其工作。 請參見下面的代碼:
from tkinter import *
from PIL import Image, ImageTk
import win32gui
import win32con
def setClickthrough(hwnd):
print("setting window properties")
try:
styles = win32gui.GetWindowLong(hwnd, win32con.GWL_EXSTYLE)
styles = win32con.WS_EX_LAYERED | win32con.WS_EX_TRANSPARENT
win32gui.SetWindowLong(hwnd, win32con.GWL_EXSTYLE, styles)
win32gui.SetLayeredWindowAttributes(hwnd, 0, 255, win32con.LWA_ALPHA)
except Exception as e:
print(e)
# Dimensions
width = 1920 #self.winfo_screenwidth()
height = 1080 #self.winfo_screenheight()
root = Tk()
root.geometry('%dx%d' % (width, height))
root.title("Applepie")
root.attributes('-transparentcolor', 'white', '-topmost', 1)
root.config(bg='white')
root.attributes("-alpha", 0.25)
root.wm_attributes("-topmost", 1)
bg = Canvas(root, width=width, height=height, bg='white')
setClickthrough(bg.winfo_id())
frame = ImageTk.PhotoImage(file="example.png")
bg.create_image(1920/2, 1080/2, image=frame)
bg.pack()
root.mainloop()
您的嘗試和工作示例之間的重要區別似乎是使用了 canvas 的hwnd
而不是 window。
我不能完全按照您的意願去做,但我提供了一些代碼來輸出這個結果並希望能滿足您的需求。 額外的代碼只是刪除了裝飾( overrideredirect(1)
)並將 window 調整為 img 大小,並將其放在屏幕中間。:
from tkinter import *
from PIL import Image, ImageTk
import win32gui
import win32con
def setClickthrough(hwnd):
print("setting window properties")
try:
styles = win32gui.GetWindowLong(hwnd, win32con.GWL_EXSTYLE)
styles = win32con.WS_EX_LAYERED | win32con.WS_EX_TRANSPARENT
win32gui.SetWindowLong(hwnd, win32con.GWL_EXSTYLE, styles)
win32gui.SetLayeredWindowAttributes(hwnd, 0, 255, win32con.LWA_ALPHA)
except Exception as e:
print(e)
def size_position_for_picture():
bbox = bg.bbox(img_id)
w,h = bbox[2]-bbox[0],bbox[3]-bbox[1]
x,y = sw/2-w/2,sh/2-h/2
root.geometry('%dx%d+%d+%d' % (w,h, x,y))
bg.configure(width=w,height=h)
root = Tk()
sw = root.winfo_screenwidth()
sh = root.winfo_screenheight()
root.overrideredirect(1)
root.attributes("-alpha", 0.75)
root.attributes('-transparentcolor', 'white', '-topmost', 1)
bg = Canvas(root,bg='white',highlightthickness=0)
root.config(bg='white')
setClickthrough(bg.winfo_id())
frame = ImageTk.PhotoImage(file="example.png")
img_id = bg.create_image(0,0, image=frame,anchor='nw')
bg.pack()
size_position_for_picture()
setClickthrough(bg.winfo_id())
root.mainloop()
我有一個 function 也在為我的應用程序執行此操作,代碼看起來與您的代碼非常相似,只是做了一些小的調整。 你可以試試:
def set_clickthrough(hwnd, root):
# Get window style and perform a 'bitwise or' operation to make the style layered and transparent, achieving
# the clickthrough property
l_ex_style = win32gui.GetWindowLong(hwnd, win32con.GWL_EXSTYLE)
l_ex_style |= win32con.WS_EX_TRANSPARENT | win32con.WS_EX_LAYERED
win32gui.SetWindowLong(hwnd, win32con.GWL_EXSTYLE, l_ex_style)
# Set the window to be transparent and appear always on top
win32gui.SetLayeredWindowAttributes(hwnd, win32api.RGB(0, 0, 0), 190, win32con.LWA_ALPHA) # transparent
win32gui.SetWindowPos(hwnd, win32con.HWND_TOPMOST, root.winfo_x(), root.winfo_y(), 0, 0, 0)
而且,下面的 function 再次禁用點擊
def disable_clickthrough(hwnd, root):
# Calling the function again sets the extended style of the window to zero, reverting to a standard window
win32api.SetWindowLong(hwnd, win32con.GWL_EXSTYLE, 0)
# Remove the always on top property again, in case always on top was set to false in options
win32gui.SetWindowPos(hwnd, win32con.HWND_NOTOPMOST, root.winfo_x(), root.winfo_y(), 0, 0, 0)
您可以通過調用win32gui.FindWindow(None, root.title())
獲取 window 句柄 ( hwnd
)。
