Installation

pip install pyqt-toast-notification

Usage

Import the Toast class, instantiate it, and show the toast notification with the show() method:

from PyQt6.QtWidgets import QMainWindow, QPushButton
from pyqttoast import Toast, ToastPreset


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

        # Add button and connect click event
        self.button = QPushButton(self)
        self.button.setText('Show toast')
        self.button.clicked.connect(self.show_toast)
    
    # Shows a toast notification every time the button is clicked
    def show_toast(self):
        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()

IMPORTANT:
An instance of Toast can only be shown once. If you want to show another one, even if the content is exactly the same, you have to create another instance.

Customization

• Setting the position of the toasts (static):

Toast.setPosition(ToastPosition.BOTTOM_MIDDLE)  # Default: ToastPosition.BOTTOM_RIGHT

AVAILABLE POSITIONS:
BOTTOM_LEFT, BOTTOM_MIDDLE, BOTTOM_RIGHT, TOP_LEFT, TOP_MIDDLE, TOP_RIGHT, CENTER

• Setting whether the toasts should always be shown on the main screen (static):

Toast.setAlwaysOnMainScreen(True)  # Default: False

• Positioning the toasts relative to a widget instead of a screen (static):

Toast.setPositionRelativeToWidget(some_widget)  # Default: None

• Setting a limit on how many toasts can be shown at the same time (static):

Toast.setMaximumOnScreen(5)  # Default: 3

If you try to show more toasts than the maximum amount on screen, they will get added to a queue and get shown as soon as one of the currently showing toasts is closed.

• Setting the vertical spacing between the toasts (static):

Toast.setSpacing(20)  # Default: 10

• Setting the x and y offset of the toast position (static):

Toast.setOffset(30, 55)  # Default: 20, 45

• Making the toast show forever until it is closed:

toast.setDuration(0)  # Default: 5000

• Enabling or disabling the duration bar:

toast.setShowDurationBar(False)  # Default: True

• Adding an icon:

toast.setIcon(ToastIcon.SUCCESS)  # Default: ToastIcon.INFORMATION
toast.setShowIcon(True)           # Default: False

# If you want to show the icon without recoloring it, set the icon color to None:
toast.setIconColor(None)  # Default: #5C5C5C

AVAILABLE ICONS:
SUCCESS, WARNING, ERROR, INFORMATION, CLOSE

• Setting the icon size:

toast.setIconSize(QSize(14, 14))  # Default: QSize(18, 18)

• Setting the close button alignment:

toast.setCloseButtonAlignment(ToastButtonAlignment.MIDDLE)  # Default: ToastButtonAlignment.TOP

AVAILABLE ALIGNMENTS:
TOP, MIDDLE, BOTTOM

• Enabling or disabling the close button:

toast.setShowCloseButton(False)  # Default: True

• Customizing the duration of the fade animations (milliseconds):

toast.setFadeOutDuration(150)  # Default: 250

• Enabling or disabling duration reset on hover:

toast.setResetDurationOnHover(False)  # Default: True

• Making the corners rounded:

toast.setBorderRadius(3)  # Default: 0

toast.setIconSeparatorColor(QColor('#585858'))    # Default: #D9D9D9
toast.setCloseButtonIconColor(QColor('#C9C9C9'))  # Default: #000000

• Setting custom fonts:

# Init font
font = QFont('Times', 10, QFont.Weight.Bold)

# Set fonts
toast.setTitleFont(font)  # Default: QFont('Arial', 9, QFont.Weight.Bold)
toast.setTextFont(font)   # Default: QFont('Arial', 9)

• Applying a style preset:

toast.applyPreset(ToastPreset.ERROR)

AVAILABLE PRESETS:
SUCCESS, WARNING, ERROR, INFORMATION, SUCCESS_DARK, WARNING_DARK, ERROR_DARK, INFORMATION_DARK

• Setting toast size constraints:

# Minimum and maximum size
toast.setMinimumWidth(100)
toast.setMaximumWidth(350)
toast.setMinimumHeight(50)
toast.setMaximumHeight(120)

# Fixed size (not recommended)
toast.setFixedSize(QSize(350, 80))
