Hi,
At my GUI application i am catching a key press action. The code is
working if i don't enable the overrideredirect. When i comment out the
overriderect part i can see the picture but i am not able to catch
the key presses. It seems like the GUI is stucked. But i want to have
windowless appereance that is just the picture itself. Also a working
application that will catch my key presses. So how can i fix it?
Here is the code part related with my question:
from Tkinter import *
from Xlib import *
import Image #PIL
import ImageTk #PIL
self.root = Tk()
#self.root.overrideredirect(1)
self.root.title("Status")
self.root.bind('<Key>', self.action)
dsp = display.Display()
self.screen = dsp.screen().root
self.screen.grab_key(self.actionkey, X.AnyModifier, 1,X.GrabModeAsync,
X.GrabModeAsync)
# we tell the X server we want to catch keyPress event
self.screen.change_attributes(event_mask = X.KeyPressMask)
def action(self,event):
#print event.keycode
if event.keycode == self.actionkey:
self.showImage()
def showImage(self,imageName="w_on_b_on.jpg"):
print imageName
im = Image.open(imageName)
xlocation = 440
ylocation = 640
width = im.size[0]+20
height = im.size[1]+20
newgeometry =
str(width)+"x"+str(height)+"+"+str(xlocation)+"+"+str(ylocation)
self.root.geometry(newgeometry)
self.root.protocol('WM_DELETE_WINDOW', self.doExit)
# add 20 to account for border defined in create_image
self.canvas = Canvas(self.root, height=im.size[1]+20,
width=im.size[0]+20)
self.canvas.pack(side=LEFT,fill=BOTH,expand=1)
photo = ImageTk.PhotoImage(im)
item = self.canvas.create_image(10,10,anchor=NW, image=photo)
self.counter += 1
#self.canvas.update()
mainloop()
I didn't check the code below, the whole working one is here:
