so if I run the code

the image I get (before/after I click a piece)
before:
after (I clicked the e2 pawn):
so I know that under the original canvas its actually displaying what I want. I just what to show to lift it but its not doing that.
when I have the delete all widgets code commented, the image does not change once I click a piece, it does not display the legal moves of the piece.
I am trying to make a full GUI, for A game borderlands 2, however it only detects my key presses when the tkinter box is selected (in focus). In a game this is not happening, so I need a way for tkinter to detect my key presses while not selected.
This is the code so far. It is not finished, ignore the "Auto Exec" and "Auto Exit" the problem is "Auto Reload". Clicking once will turn it ON and again will turn it OFF. Just choose any number (1-4) for the weapon slot, does not affect the error.

I need a way for tkinter to detect my key presses while not selected
You can't use tkinter for that. It can only detect keyboard events when it has the keyboard focus. You will have to use some platform-specific library to do what you want.
I am looking to make the background of the tkinter canvas transparent, but still have Mouse events of the canvas, here is my code, I am on Windows 10, Python 3.6:
from tkinter import *
import time
WIDTH = 500
HEIGHT = 500
LINEWIDTH = 1
TRANSCOLOUR = 'gray'
global old
old = ()
tk = Tk()
tk.title('Virtual whiteboard')
tk.wm_attributes('-transparentcolor', TRANSCOLOUR)
canvas = Canvas(tk, width=WIDTH, height=HEIGHT)
canvas.pack()
canvas.config(cursor='tcross')
canvas.create_rectangle(0, 0, WIDTH, HEIGHT, fill=TRANSCOLOUR, outline=TRANSCOLOUR)
def buttonmotion(evt):
global old
if old == ():
old = (evt.x, evt.y)
return
else:
canvas.create_line(old[0], old[1], evt.x, evt.y, width=LINEWIDTH)
old = (evt.x, evt.y)
def buttonclick(evt):
global old
canvas.create_line(evt.x-1, evt.y-1, evt.x, evt.y, width=LINEWIDTH)
old = (evt.x, evt.y)
canvas.bind('<Button-1>', buttonmotion)
canvas.bind('<B1-Motion>', buttonclick)
while True:
tk.update()
time.sleep(0.01)
When run the code, it makes a transparent background, but I select the things under, instead of the canvas.
I build a little workaround with the help of the win api, here is my suggestion:
from tkinter import *
import time
import win32gui
import win32api
WIDTH = 500
HEIGHT = 500
LINEWIDTH = 1
TRANSCOLOUR = 'gray'
title = 'Virtual whiteboard'
global old
old = ()
global HWND_t
HWND_t = 0
tk = Tk()
tk.title(title)
tk.lift()
tk.wm_attributes("-topmost", True)
tk.wm_attributes("-transparentcolor", TRANSCOLOUR)
state_left = win32api.GetKeyState(0x01) # Left button down = 0 or 1. Button up = -127 or -128
canvas = Canvas(tk, width=WIDTH, height=HEIGHT)
canvas.pack()
canvas.config(cursor='tcross')
canvas.create_rectangle(0, 0, WIDTH, HEIGHT, fill=TRANSCOLOUR, outline=TRANSCOLOUR)
def putOnTop(event):
event.widget.unbind('<Visibility>')
event.widget.update()
event.widget.lift()
event.widget.bind('<Visibility>', putOnTop)
def drawline(data):
global old
if old !=():
canvas.create_line(old[0], old[1], data[0], data[1], width=LINEWIDTH)
old = (data[0], data[1])
def enumHandler(hwnd, lParam):
global HWND_t
if win32gui.IsWindowVisible(hwnd):
if title in win32gui.GetWindowText(hwnd):
HWND_t = hwnd
win32gui.EnumWindows(enumHandler, None)
tk.bind('<Visibility>', putOnTop)
tk.focus()
running = 1
while running == 1:
try:
tk.update()
time.sleep(0.01)
if HWND_t != 0:
windowborder = win32gui.GetWindowRect(HWND_t)
cur_pos = win32api.GetCursorPos()
state_left_new = win32api.GetKeyState(0x01)
if state_left_new != state_left:
if windowborder[0] < cur_pos[0] and windowborder[2] > cur_pos[0] and windowborder[1] < cur_pos[1] and windowborder[3] > cur_pos[1]:
drawline((cur_pos[0] - windowborder[0] - 5, cur_pos[1] - windowborder[1] - 30))
else:
old = ()
except Exception as e:
running = 0
print("error %r" % (e))
Shot explanation of the new code bits:
tk.lift()
tk.wm_attributes("-topmost", True)
...
def putOnTop(event):
event.widget.unbind('<Visibility>')
event.widget.update()
event.widget.lift()
event.widget.bind('<Visibility>', putOnTop)
...
tk.bind('<Visibility>', putOnTop)
tk.focus()
These lines ensure, that the window will be always be on top of all other windows.
global HWND_t
HWND_t = 0
...
def enumHandler(hwnd, lParam):
global HWND_t
if win32gui.IsWindowVisible(hwnd):
if title in win32gui.GetWindowText(hwnd):
HWND_t = hwnd
win32gui.EnumWindows(enumHandler, None)
This code bit will go through all the windows currently displayed and catches the handle of the whiteboard window (make sure the title is unique, or this could capture the wrong handle).
state_left = win32api.GetKeyState(0x01)
...
if HWND_t != 0:
windowborder = win32gui.GetWindowRect(HWND_t)
cur_pos = win32api.GetCursorPos()
state_left_new = win32api.GetKeyState(0x01)
if state_left_new != state_left:
if windowborder[0] < cur_pos[0] and windowborder[2] > cur_pos[0] and windowborder[1] < cur_pos[1] and windowborder[3] > cur_pos[1]:
drawline((cur_pos[0] - windowborder[0] - 5, cur_pos[1] - windowborder[1] - 30))
else:
old = ()
This
Checks, if the handle is found
Checks, if mouse button 1 is clicked or not
Checks, if mouse is inside the window
if all is true, it takes the mouse data and draws the line
the current mode is, that it doesn't draw anything till the button is clicked and then draws until the button is clicked again.
I'm sure you've thought of this, but have you tried setting the hexadecimal colour as ""?
i.e
canvas = tk.Canvas(width, height, bg = "")
That works for my version of python.
I'm trying to program a game in Tkinter (trust that I'd much rather use another better-suited library), and I'm having trouble coding in animations. I tried 2 ways of working around the problem but both have failed.
What I've done is to write an Animation class, which, in my first implementation, takes a list of PhotoImages, and deletes/draws each frame:
class Animation():
def __init__(self, container, pos, images, framerate):
self.container = container
self.x = pos[0]
self.y = pos[1]
self.images = copy(images)
self.imagescopy = copy(images)
self.framerate = framerate # ms between frames
self.done = False
def animate(self):
if len(self.images)>0:
self.container.delete("currentframe")
self.container.create_image(self.x, self.y, image = self.images.pop(0), tag = "currentframe")
self.animation = self.container.after(self.framerate, self.animate)
else:
self.container.delete("currentframe")
self.container.after_cancel(self.animation)
self.done = True
In the init method of the class which draws the Tk window, I loaded the PhotoImages (I tried this with a simple placeholder 5 frame animation):
for i in range(1,6):
self.imgs_playbgready.append(PhotoImage(file ='Graphics\\PlayArea\\ani_bgready'+str(i)+'.gif'))
But when I try to execute the program, it takes very very long to load beyond the third image. Even writing out each line explicitly like so:
self.imgs_playbgready = [PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready1.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready2.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready3.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready4.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready5.gif') ]
didn't help. Removing the last 2 items seems to make everything fine, so it looks like there's a limit on 3 PhotoImages in a list though I can't imagine why that'd be the case?
In my second implementation, I tried to change the animate method so that the PhotoImages would be 'lazily loaded' (so now self.images is a list of file names rather than PhotoImages):
def animate(self):
if len(self.images)>0:
self.container.delete("currentframe")
image = PhotoImage(file = self.images.pop(0))
self.container.create_image(self.x, self.y, image = image, tag = "currentframe")
self.animation = self.container.after(self.framerate, self.animate)
else:
self.container.delete("currentframe")
self.container.after_cancel(self.animation)
self.done = True
Now when I try to run the program it freezes at frame 4 and I have to force quit. Again, it seems 3 is the magic number?
I'm not really sure at all what's going on with this. From googling about animation in Tkinter, redrawing PhotoImages frame by frame seems the way to go. Please be patient with me because I only started learning to use the Tkinter library last week. Any help is much appreciated.
EDIT
Thanks for your help.
To clarify the points raised in the comment (full working code at the end):
It takes a few minutes before the last two images load in and the program starts up. My framerate as defined in the Animation class is more like an inverse framerate (number of miliseconds between each redraw) as you can see in the animate function. My whole code is really quite long so I will try to extract the more relevant parts (for the first implementation I tried). Basically in my GUI class (named PlayArea), under the __init__ method, I try to load in the image list for the animation as well as create an Animation instance:
class PlayArea():
def __init__(self):
self.window = Tk()
.....
#---------------------
# Button and background images
#---------------------
......
self.imgs_playbgready = [PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready1.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready2.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready3.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready4.gif'),
PhotoImage(file = 'Graphics\\PlayArea\\ani_bgready5.gif') ]
.......
self.ani_playbgready = Animation(self.playCanvas,(self.playWidth/2, self.playHeight/2),self.imgs_playbgready, 5000)
The animation will only run after a user clicks a button, and the command callback for the button is this(I've put in only the relevant portions):
startGame(self):
# Play Area
self.playCanvas.delete("bgready")
self.ani_playbgready.animate() # animating the images
I know for sure that the program is freezing up after loading the third PhotoImage, because when I try to do the loading using a for loop, and print the list after each loop, I can see it hang up in the fourth one. As mentioned, this code works as long as I only load 3 images into the list. In other words, it probably isn't a problem with my animate method

I am an atmospheric scientist, struggling through python (2.7 using PIL and Tkinter) in an attempt to create a simple image viewer that will display some of the forecast products we eventually produce. I would like to implement a start, stop, forward, backward, and loop button. The loop button and its associated callback currently work correctly. The loop method is credited to Glenn Pepper (found an open-source project via google).
Here is the code:
from Tkinter import *
from PIL import Image, ImageTk
import tkMessageBox
import tkFileDialog
#............................Button Callbacks.............................#
root = Tk()
root.title("WxViewer")
root.geometry("1500x820+0+0")
def loop():
StaticFrame = []
for i in range(0,2):
fileName="filename"+str(i)+".gif"
StaticFrame+=[PhotoImage(file=fileName)]
def animation(currentframe):
def change_image():
displayFrame.create_image(0,0,anchor=NW,
image=StaticFrame[currentframe], tag='Animate')
# Delete the current picture if one exist
displayFrame.delete('Animate')
try:
change_image()
except IndexError:
# When you get to the end of the list of images -
#it simply resets itself back to zero and then we start again
currentframe = 0
change_image()
displayFrame.update_idletasks() #Force redraw
currentframe = currentframe + 1
# Call loop again to keep the animation running in a continuous loop
root.after(1000, animation, currentframe)
# Start the animation loop just after the Tkinter loop begins
root.after(10, animation, 0)
def back():
print("click!")
def stop():
print("click!")
def play():
print("click!")
def forward():
print("click!")
#..........................ToolFrame Creation............................#
toolFrame = Frame(root)
toolFrame.config(bg="gray40")
toolFrame.grid(column=0,row=0, sticky=(N,W,E,S) )
toolFrame.columnconfigure(0, weight = 1)
toolFrame.rowconfigure(0, weight = 1)
toolFrame.pack(pady = 0, padx = 10)
backButton = Button(toolFrame, text="Back", command = back)
backButton.pack(side = LEFT)
stopButton = Button(toolFrame, text = "Stop", command = stop)
stopButton.pack(side = LEFT)
playButton = Button(toolFrame, text = "Play", command = play)
playButton.pack(side = LEFT)
forwardButton = Button(toolFrame, text = "Forward", command = forward)
forwardButton.pack(side = LEFT)
loopButton = Button(toolFrame, text = "Loop", command = loop)
loopButton.pack(side = LEFT)
toolFrame.pack(side = TOP, fill=X)
#........................DisplayFrame Creation..........................#
displayFrame = Canvas(root, width=1024,height=768)
displayFrame.config(bg="white")
displayFrame.grid(column=0,row=0, sticky=(N,W,E,S) )
displayFrame.columnconfigure(0, weight = 1)
displayFrame.rowconfigure(0, weight = 1)
displayFrame.pack(pady = 5, padx = 10)
displayFrame.pack(side = LEFT, fill=BOTH)
#...............................Execution...............................#

It is rather straightforward. I have searched GitHub for projects, google, and stackoverflow but I am unsure how to make these five methods play nicely with each other. Could anyone share some pointers on how I could construct these other four methods so that they work appropriately? Thank you for your time!
I would replace the current loop function with something like the following (untested). The changes: add some global names to share data between functions; make change_image do everything needed to change an image, given that current_image is valid; except for the starting value, make current_image be always a valid image number when it is changed; factor forward() out of animate() (which is just repeated times forward calls).
n_images = 2
images = [PhotoImage(file="filename"+str(i)+".gif") for i in range(n_images)]
current_image = -1
def change_image():
displayFrame.delete('Animate')
displayFrame.create_image(0,0, anchor=NW,
image=StaticFrame[current_image], tag='Animate')
displayFrame.update_idletasks() #Force redraw
callback = None
def animate():
global callback
forward()
callback = root.after(1000, animate)
Here are three of the other functions.
def forward():
global current_image
current_image += 1
if current_image >= n_images:
current_image = 0
change_image()
def back():
global current_image
current_image -= 1
if current_image < 0:
current_image = n_images-1
change_image()
def stop():
if callback is not None:
root.after_cancel(callback)
