As a title sometimes the notification does not appear and goes directly into the notification area without sounding or appearing

increases the notification counter and does not show it

In the following code:

from win10toast import ToastNotifier
from time import sleep

notify = ToastNotifier()

notify.show_toast("Testing!", "Hopefully the test goes well...", "info.ico", 10, True)
sleep(4)
notify.show_toast("Testing! #2", "Hopefully the test goes well... (again)", "info.ico", 10, True)
print("End")

Only the first notification shows, and then goes straight to printing "End", without showing the second notification.

I am using Python 3.5.4 and Windows 10 Home Fall Creators Update (1709).

Right now I am trying to display five lines of a notification but the system is only able to display first 4 lines. Is it the limitation or am i missing something.

Would be much better to have this class either in __init__.py or its own file

This is especially weird because __name__ is either __main__ or win10toast.__main__

When I try to pip install win10toast , I get the error message

Collecting pywin32 (from win10toast)
Could not find a version that satisfies the requirement pywin32 (from win10toast) (from versions: )
No matching distribution found for pywin32 (from win10toast)

I guess it's becuase the version in PyPI has not been updated yet, to install pypiwin32, instead of pywin32.

Looking primarily to get the multi-threading code pushed to pypi for a project that relied upon pip for package installation.

Hello!

I am getting an error when trying to import this into my project:

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    from win10toast import ToastNotifier
  File "C:\Users\Luka\AppData\Roaming\Python\Python38\site-packages\win10toast\__init__.py", line 19, in <module>
    from win32api import GetModuleHandle
ModuleNotFoundError: No module named 'win32api'

It seems win32api is missing. So I go ahead and install it with this command: python -m pip install win32api --user. I have to use --user as I am not an admin on my PC. The following error occurs...

ERROR: Could not find a version that satisfies the requirement win32api (from versions: none)
ERROR: No matching distribution found for win32api

So I try: python -m pip install pypiwin32 --user, as this is listed in requirements section. I already have it.
I am using Python 3.8.0 and IDLE, on a Windows 10 PC.

So what am I doing wrong?
Thanks!

'ToastNotifier' object has no attribute 'classAtom'

I would like to be able to dismiss any notifications I have created.

I think this could be achieved with a function that takes the handle of the notification to be cancelled, and with show_toast returning the handle of the new notification.

I'm sort of missing the fact that this even works on Windows 7 in the README....
that's not a total obvious fact...

how can i set size for the notifications ?? such as with andlength ?? thanks...

I used a 256x256 pixel .ico file for the icon but the icon is rather small. I think it might be an issue with my high dpi screen.

Is there any way to make the icon appear larger? Thank you very much.

When you click the notification is it possible to select the application that triggered the notification?

Or am I doing it wrong?

When trying to pack into an exe with pyinstaller many user got an error that something went wrong despite everything working correctly on script. I have found the issue to be the preconfigured icon because pyinstaller does not recognize it as a resource when running as an exe.
Solution:
just pass a custom icon in the toast. you will get an error not finding it if it's not in exe's folder but it will work

It seems like the program automatically exit after toast being run. Is there any way to sustain the application?

I was in the process of adding this functionality in order to make a pull request, but sadly there were some limitations, and I don't know enough about ctypes to use it effectively.

So far, I imagine it working like this: It would support PyQt5 and PySide2. There can be a simple flag that can be passed useQtResource, which can flag to use a Qt resource instead.

Now, awesomely enough, Qt comes with its own function toHICON. Great, right? Yes, but unfortunately, for whoever knows what reason, PySide2 (the official Qt Python bindings supported by Nokia) doesn't make QtWin available, whereas PyQt does! If the user is using PyQt, you could probably still make use of the toHICON function.

--
P.S. for sake of completeness, here's a toHICON code example.

pixmap = QPixmap(icon_path)
HICON = QtWin.toHICON(QPixmap)

Pretty simple isn't it?

--

Please note that if you choose to use the toHICON function for PyQt, you will have to include an additional flag useQtapi='pyside2' (or pyqt5). Why? Because the lovely qtpy (qtpy is a import library which allows you to abstract away the differences between API's, so you don't have to write or test for multiple APIs, thus, we wouldn't have to specify which API to use) also decided not to include QtWin! Seriously? Why's everybody forgetting to include important modules in their official distributions?

As for PySide2, as are the cirucmstances, I've found a way to get the raw image data from the resources. QResource(':/resource.ico').data().tobytes() will get you the raw image data represented as a Python string. Using this, I managed to cobble together a ctypes interface to convert it into a HICON using CreateIconFromResourceEx. The code looks like the following:

from ctypes import *
from ctypes.wintypes import *

CreateIconFromResourceEx = windll.user32.CreateIconFromResourceEx
size_x, size_y = 32, 32
LR_DEFAULTCOLOR = 0

imgData = QResource(icon_path).data().tobytes()
hicon = CreateIconFromResourceEx(iconData, len(iconData), 1, 0x30000, size_x, size_y, LR_DEFAULTCOLOR)

Looks lovely right? It works, but ... Yeah. It only works on PNG images, not on ICO images. :/ Frustrating. After several searching and API lookups, I found this piece of C code for ICO files.

int offset = LookupIconIdFromDirectoryEx(iconData, TRUE, iconSize, iconSize, LR_DEFAULTCOLOR);     

   if (offset != 0) {     

      hIcon = CreateIconFromResourceEx(iconData + offset, 0, TRUE, 0x30000, iconSize, iconSize, LR_DEFAULTCOLOR);     

   }

I managed to Pythonize it, but, I should warn you, iconData + offset isn't actually valid, because you cant concatenate a bytes and an int data type. I had to use offset.to_bytes(len(offset), byteorder=sys.byteorder). Well, this passed the test... No Exceptions, BUT, HICON is always 0. Anyways, no matter what I try to do, I can't get this to work with an ICO file. Yeah, I could just write the file to the disk and read it again, but that's just UGLY.

CreateIconFromResourceEx = windll.user32.CreateIconFromResourceEx
LookupIconIdFromDirectoryEx =  windll.user32.LookupIconIdFromDirectoryEx
size_x, size_y = 32, 32
LR_DEFAULTCOLOR = 0

imgData = QResource(icon_path).data().tobytes()

# works
offset = LookupIconIdFromDirectoryEx(iconData, 1, size_x, size_y, LR_DEFAULTCOLOR)
# "works", as in, won't return an exception, but it ALWAYS returns 0 (using ICO files)
hicon = CreateIconFromResourceEx(iconData + offset.to_bytes(len(offset), byteorder=sys.byteorder), 0, 1, 0x30000, size_x, size_y, LR_DEFAULTCOLOR)

So, this is where I'm at. I can do all this AS LONG as the image is a PNG, not ICO. Also, since I don't have PyQt5, I can't get toHICON, but that shouldn't be too hard for you to implement.

Any suggestions for fixing this? I'll be glad to throw a pull request if we can solve this. Please help me make this a reality.

-- Speaking of which, your code can only read an ICO image, not an PNG image. It would be nice if it supported PNG as well. As I tested PNG above, I know it works with the system as long as you can convert it to a HICON.

-- Also, I know absolutely nothing about C or ctypes, so please forgive any "obvious mistakes".

Probably the most important question: Why?

Because when you compile Python programs to an exe, and you use Qt, you will want to use the resource system (after all, you don't want raw files lying around when it can become part of the code).

Hi, very nifty python package you've compiled here. However, whenever I use multiple toaster messages within a python file (I have one go off for each function in my file), I notice a significant delay when waiting on the next section of the program to run.

I noticed you're using multi-threading to handle the use of multiple messages. Have you considered trying multi-processing instead? Python was not really built to support multi-threading, and it's very hit or miss if it (ever) works as intended. On the other hand, Python was built to support multi-processing. If we could swap the use of multi-threading with processing, I believe this may solve part of the slowdown issue mentioned earlier.

I ran the code below,
from win10toast import ToastNotifier
toaster = ToastNotifier()
toaster.show_toast("Hello World!!!",
"Python is 10 seconds awsm!",
icon_path=None,
duration=10
)
I got the error below
Traceback (most recent call last):
File "D:\python_workspace\ding.py", line 6, in <module>
duration=10
File "C:\Users\shi\AppData\Local\Programs\Python\Python36-32\lib\site-packages\win10toast\__init__.py", line 98, in show_toast
Shell_NotifyIcon(NIM_ADD, nid)
pywintypes.error: (-2147467259, 'Shell_NotifyIcon', '未指定的错误')
[Finished in 0.7s with exit code 1]

And, when I added
threaded = True
it told me
TypeError: show_toast() got an unexpected keyword argument 'threaded'

It confused me because last time I ran the code, it was absolutely alright. :(
Thanks a lot.

setuptools is required for pkg_resources to be available

I have a simple Qt window it has a button and when you click the button it opens a explorer window for a specific location, when the notification fades out the window closes as well.

Entire Example Script
`class Example(QWidget):

def __init__(self):
    super().__init__()
    self.initUI()

@pyqtSlot()
def on_click(self):
    print('PyQt5 button click')

    toaster = ToastNotifier()
    toaster.show_toast("TITLE",
                       "Python is 10 seconds awsm! and I think that this is the way to go for all information going forward",

The app GUI always freezes after running a method with toast notif in it... idk but you may give yourself a try...
this method is a member of a tkinter toplevel class which i invoke when user clicks a button

def mymethod(self):
        hs = generate_hash()
        newpath = f'..\\results\\results{hs}\\'
        
        os.makedirs(newpath)
        X = readall_images(self.inputvar.get())
        saveall_images(X, newpath, "")
        
        opennotif(newpath, "Done", "open it!")
        
        self.inputvar.set("")
        X = None

on the top on it, I import a function I made dedicated for toast notification... the function looks like this:

def opennotif(dir, header, msg):
    tst = ToastNotifier()
    res = tst.show_toast(str(header), str(msg))

    if res is True:
        os.system(f'explorer "{dir}"')

The class can not be instantiated for any other instance.
It is not possible to have a second notifier instance running with different purpose.
from win10toast import ToastNotifier as T
t1=T() #instance 1
t2=T() #instance 2
Raises class already exists error.

hey i want to toast 2 notification at the same time
but the code can run 1 toast
when i run 2 toast the first toast is dissapear

So while building the project, I have encountered an issue with pip module while in setup.py

In pip versions greater than 10 parse_requirements is in pip._internal.req instead of pip.req. Here is a snippet on how I fixed it.

I write my code in Pycharm and import all the libraries from the built-in pip module. I've done the same with win10toast, and as long as I launch the code from Pycharm it works great, but after converting the project into an executable file the notifications are not shown at all.

Here's the code:
import win10toast
toaster = win10toast.ToastNotifier()
toaster.show_toast("Test", "Hello", duration=5, threaded=True)

I was just testing the library's capabilities so it's just a simple code. I've tried converting it to exe with pyinstaller from windows 10 cmd, as well as py2exe.net

Please let me know if it's just a problem that occurrs on my machine or is it to do with the way the library is written or maybe even with the conversion to exe itself. Thank you in advance.

This is a bit similar to #46 but I was curious how to add images to the notifications. Similar to the news article notifications that you would see on the Windows Action Center, I'd love to be able to attach a picture with sizing dimensions in addition to my message.

The syntax could be something like this:

toaster.show_toast("Today's Weather!", 
                    "It's Cloudy Today",
                    image_path="http://icon-park.com/imagefiles/simple_weather_icons_cloudy.png",
                    image_width="600px",
                    image_height="600px",
                   icon_path="custom.ico",
                   duration=10)

Hello,

I have installed the "win10toast" module using follwing command:

pip install win10toast

If I try to import the module using:

from win10toast import ToastNotifier

I keep getting this error:

ModuleNotFoundError: No module named 'win10toast'

These lines

Should be stripped of their surrounding if statement, and moved to __main__.py.

That way, the example can be run with python -m win10toast

Hi, this looks really great. But in windows 10 the notification does not persist in the action center

When i am displaying an icon in the notification it appears to be quite small no matter what size/resolution icon file i have. Is there a way to make the icon appear bigger in the notification?

is possible that the notification will remain in the Notification Center ?

Even after the BalloonTip disappeared, the icon is still present until a mouseover.

In your readme.md please change your example to:

from win10toast import ToastNotifier
import time

toaster = ToastNotifier()
toaster.show_toast("Hello World!!!",
                   "Python is 10 seconds awsm!",
                   icon_path="custom.ico",
                   duration=10)

toaster.show_toast("Example two",
                   "This notification is in it's own thread!",
                   icon_path=None,
                   duration=5,
                   threaded=True)
# Wait for threaded notification to finish
while toaster.notification_active(): time.sleep(0.1)

It doesn't matter much, but would be easier to copy-paste :)

Since you updated win10toast in the pip repository, installation does not work anymore for me. It looks like the requirements.txt file can not be found. For reference, this is the error:

Please help me fix, thank so much

Hello, i wonder if you're still maintaining and keeping an eye on this, if so please respond so i don't waste my time explaining my problem to a wall :)

Add UnregisterClass after DestroyWindow (here).

Otherwise if I wrote a script like your example and exec it twice in python interpreter, there would be error messages saying that class already exist.

And that's because destroying the windows doesn't unregister the class.

Is this possible? I've tried duration = 0 but that seems to close it after a little while anyway (I'm using threaded notifications if that makes a difference)

Basically I want "high priority" toasts to stack and stay around until the user manually acknowledges them

Hi,

I've been using this library for a long time and never had any problems. Recently I let Windows update with it's latest update, and right after that I stopped getting notification from my program. I tested this by creating a simple python file with only the sample code of this library and again the notification didn't popup. I noticed whenever the notification was supposed to popup it will only show an icon in the system tray and not show the notification.

I suspect this has to do with Windows' feature of "Focus Assist" that I only noticed recently. I also noticed that there is a white-list of programs in the "Notifications & Actions" section of Settings, where you can enable or disable notifications from certain programs and sources, which I'm not sure was there before.

Would really appreciate a feedback on this as this library is very crucial for my application.

Thank you.

No matter how much duration value set, the toast always destructs after some specified time (around 3 seconds). Please take a look into this.

If you're not seeing your toasts while using this module - check "Focus Assist" under System > Focus Assist.

I had to set Focus Assist to "Off" for the toasts to show up.

You may be able to set it back to a stricter setting once you're done coding your app - I'm not there yet.

(I'm primarily a Linux coder, where our systems don't try to be so bloody helpful on their own, so this took me a while to track down. But it works. Yay toast.)
