透明色Tkinter

Question

是否可以將框架背景或任何其他控件的顏色更改爲透明淡藍色或任何其他透明色？

Answer 1

是的，有一種方法。不幸的是，它只適用於整個窗口（窗口和所有子窗口小部件）。

這是我前一段時間寫的一個小小的演示，其中包含了你想做的事情。

透明窗口演示：

import Tkinter as Tk, re 




class TransparentWin (Tk.Tk) : 
    ''' Transparent Tk Window Class ''' 

    def __init__ (self) : 

     Tk.Tk.__init__(self) 

     self.Drag = Drag(self) 

     ''' Sets focus to the window. ''' 
     self.focus_force() 

     ''' Removes the native window boarder. ''' 
     self.overrideredirect(True) 

     ''' Disables resizing of the widget. ''' 
     self.resizable(False, False) 

     ''' Places window above all other windows in the window stack. ''' 
     self.wm_attributes("-topmost", True) 

     ''' This changes the alpha value (How transparent the window should 
      be). It ranges from 0.0 (completely transparent) to 1.0 
      (completely opaque). ''' 
     self.attributes("-alpha", 0.7) 

     ''' The windows overall position on the screen ''' 
     self.wm_geometry('+' + str(439) + '+' + str(172)) 

     ''' Changes the window's color. ''' 
     bg = '#3e4134' 

     self.config(bg=bg) 

     self.Frame = Tk.Frame(self, bg=bg) 
     self.Frame.pack() 

     ''' Exits the application when the window is right clicked. ''' 
     self.Frame.bind('<Button-3>', self.exit) 

     ''' Changes the window's size indirectly. ''' 
     self.Frame.configure(width=162, height=100) 

    def exit (self, event) : 
     self.destroy() 

    def position (self) : 

     _filter = re.compile(r"(\d+)?x?(\d+)?([+-])(\d+)([+-])(\d+)") 

     pos = self.winfo_geometry() 

     filtered = _filter.search(pos) 
     self.X = int(filtered.group(4)) 
     self.Y = int(filtered.group(6)) 

     return self.X, self.Y 

class Drag: 
    ''' Makes a window dragable. ''' 

    def __init__ (self, par, dissable=None, releasecmd=None) : 

     self.Par  = par 
     self.Dissable = dissable 

     self.ReleaseCMD = releasecmd 

     self.Par.bind('<Button-1>', self.relative_position) 
     self.Par.bind('<ButtonRelease-1>', self.drag_unbind) 


    def relative_position (self, event) : 

     cx, cy = self.Par.winfo_pointerxy() 
     x, y = self.Par.position() 

     self.OriX = x 
     self.OriY = y 

     self.RelX = cx - x 
     self.RelY = cy - y 

     self.Par.bind('<Motion>', self.drag_wid) 

    def drag_wid (self, event) : 

     cx, cy = self.Par.winfo_pointerxy() 

     d = self.Dissable 

     if d == 'x' : 
      x = self.OriX 
      y = cy - self.RelY 
     elif d == 'y' : 
      x = cx - self.RelX 
      y = self.OriY 
     else: 
      x = cx - self.RelX 
      y = cy - self.RelY 

     if x < 0 : 
      x = 0 

     if y < 0 : 
      y = 0 

     self.Par.wm_geometry('+' + str(x) + '+' + str(y)) 

    def drag_unbind (self, event) : 

     self.Par.unbind('<Motion>') 

     if self.ReleaseCMD != None : 
      self.ReleaseCMD() 


    def dissable (self) : 

     self.Par.unbind('<Button-1>') 
     self.Par.unbind('<ButtonRelease-1>') 
     self.Par.unbind('<Motion>') 


def __run__() : 

    TransparentWin().mainloop() 


if __name__ == '__main__' : 

    __run__()
