cannot set position

[gidhoog]

Hello!

I cannot set the position of the toast.

I do this:

def show_toast(self):
        Toast.setPosition(ToastPosition.BOTTOM_MIDDLE)  # set the position here !!?
        toast = Toast(self)
        toast.setDuration(5000)  # Hide after 5 seconds
        toast.setTitle('Success! Confirmation email sent.')
        toast.setText('Check your email to complete signup.')
        toast.applyPreset(ToastPreset.SUCCESS)  # Apply style preset
        toast.show()

What I am doing wrong?

Thank you!

EDIT:

Works on Windows10, but not on Linux! Should it work on Linux, or is there an other positioning code?

Hello, @gidhoog

I did some code to you understand.

First, you have to define the toast (toast = Toast(self)) and then set the position in 'toast' variable (toast.setPosition(ToastPosition.BOTTOM_MIDDLE))

Follow the example, i did with Pyside6, to do that install the Pyside6 and pyqttoast for this.

from PySide6.QtWidgets import QMainWindow, QPushButton, QVBoxLayout, QWidget, QApplication
from pyqttoast import Toast, ToastPreset, ToastPosition

class Window(QMainWindow):
    def __init__(self):
        super().__init__(parent=None)

        central_widget = QWidget(self)
        layout = QVBoxLayout(central_widget)

        self.button_middle = QPushButton('Show toast_middle', self)
        self.button_middle.clicked.connect(self.show_toast_middle)
        layout.addWidget(self.button_middle)
        
        self.button_right = QPushButton('Show toast_right', self)
        self.button_right.clicked.connect(self.show_toast_right)
        layout.addWidget(self.button_right)
        
        self.button_left = QPushButton('Show toast_left', self)
        self.button_left.clicked.connect(self.show_toast_left)
        layout.addWidget(self.button_left)

        self.setCentralWidget(central_widget)

    def show_toast_middle(self):
        toast = Toast(self)
        toast.setPosition(ToastPosition.BOTTOM_MIDDLE)
        toast.setDuration(5000)  # Hide after 5 seconds
        toast.setTitle('Success! Confirmation email sent.')
        toast.setText('Check your email to complete signup.')
        toast.applyPreset(ToastPreset.SUCCESS)
        toast.show()
    
    def show_toast_left(self):
        toast = Toast(self)
        toast.setPosition(ToastPosition.BOTTOM_LEFT)
        toast.setDuration(5000)  # Hide after 5 seconds
        toast.setTitle('Success! Confirmation email sent.')
        toast.setText('Check your email to complete signup.')
        toast.applyPreset(ToastPreset.SUCCESS)
        toast.show()
    
    def show_toast_right(self):
        toast = Toast(self)
        toast.setPosition(ToastPosition.BOTTOM_RIGHT)
        toast.setDuration(5000)  # Hide after 5 seconds
        toast.setTitle('Success! Confirmation email sent.')
        toast.setText('Check your email to complete signup.')
        toast.applyPreset(ToastPreset.SUCCESS)
        toast.show()

  if __name__ == '__main__':
      import sys
      app = QApplication(sys.argv)
      window = Window()
      window.show()
      sys.exit(app.exec())

Hello @mateusmengatto,

thank you for the example, this works now (on Windows10, tested befor on Linux, where it not worked).

But how do I use correct setPositionRelativeToWidget ?
I didn't get it to work up till now (the toast is always in the top-left corner of the main-screen).

[mateusmengatto]

@gidhoog I got it your doubt

try to use this before to set position:

toast.setPositionRelativeToWidget(self.your_widget)

or just:

toast.setPositionRelativeToWidget(self)

In Window it works. Please give-me your feedback.

Hello @mateusmengatto,

I made an example in windows as you said, and it works here.
But in my application were I want this function, I get the TypeError 'MyWidget' object is not callable pointed to the line while parent.parent() is not None: in the method get_top_level_parent in the Utils class.

MyWidget is a custom QWidget, adding a simple __call__ function (with pass) do not solve the problem.

Hey, @gidhoog

Could you give me some code example from your app?

[gidhoog]

Hi @mateusmengatto

this is not so easy. I am working on an application based on pyqgis and other (SqlAlchemy, PyQt, ...). E.g. I use QgsApplication and many other pyqt5 classes which are modified in pyqgis. I am developing on Linux and Windows

I was searching for an in-app-notification tool for this app and found this package (pyqt-toast-notification), which works excelent for this job and looks also very nice.
I have in my application a lot of input-widget, where the effects of the values and the usage is not so clear. Current I use an extended 'tool-tip' to inform the user. My idea now was to use a toast-widget for user-information too, because I like it very well (progress-bar to display fade-out, keep alive on hover, clickable hyperlinks, ...). I have already implemented multiline-support. By adding html-styled text I can display complex informations very smart.
For now I use the toast position 'TOP_MIDDLE' to display this infos, when I have more time will try to bind the info-dialog better to the input-widget.

Have you got a hint to implement this?

[mateusmengatto]

Hello @gidhoog,

I ran into some issues when implementing pyqt-toast-notification in my application. I had to make some modifications to the source code and change parts of the core of pyqt-toast to address these problems. Specifically, I needed to create a menu within the notification, remove the timeout, and use the notifications as a conversation system between workers, including statuses like "Read", "Opened", and "Concluded" in an ERP.

So, I encourage you to consider making modifications to pyqt-toast-notification to fix or add a function that allows setting an exact position for the notification. If you look at the source code, the position is currently related to the QRect of the screen or widget. But if you capture the exact position of the specific widget you want, it becomes simple to place the notification precisely on the screen.

Best regards, and good luck!

Thank you, I will try

I am experiencing the same issue. I have tested it out with the demo application (PyQt5, 6 and Pyside6) in this project, and everything seems to be working, however when I try to update the position from the static settings, it just keeps showing the toast notification in the center, and all subsequent toast on top of each other.

OS ubuntu 24.04
python version 3.12.3
pyqt-toast-notification==1.3.3
PyQt6==6.9.1
PyQt5==5.15.11
PySide6==6.9.1

[jeroenjvdb]

I have continued testing with this and the issue is (at least for me) that ubuntu is transitioning from xorg to wayland. When logging in to your ubuntu there's a cogwheel where you can select if you use ubuntu with wayland or with xorg.

When logging in with xorg it worked as expected

[epitavy]

I am experiencing the same issue than @jeroenjvdb . All the toasts appear stacked in the middle of the screen, changing the position has no effect. And indeed, I am using wayland under KDE Plasma 6.

[epitavy]

I didn't see but a similar issue has been closed as won't fix since the issue is more related to PySide6 with Wayland #7 .
There is this fix that is probably the fastest workaround : fallback to X11 so that we don't have issues with Wayland.

import os
import sys

if sys.platform.startswith("linux"):
    session_type = os.environ.get("XDG_SESSION_TYPE", "").lower()
    if session_type == "wayland":
        os.environ.setdefault("QT_QPA_PLATFORM", "xcb")
