PyQt Tooltip

A modern and fully customizable tooltip library for PyQt and PySide

Features

• Fixed and automatic placement
• Supports fallback placements
• Customizable triangle
• Customizable animations and delays
• Fully customizable and modern UI
• Works with PyQt5, PyQt6, PySide2, and PySide6

Installation

pip install pyqttooltip

Usage

from PyQt6.QtWidgets import QMainWindow, QPushButton
from pyqttooltip import Tooltip, TooltipPlacement


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

        # Add button
        self.button = QPushButton('Button', self)
        
        # Add tooltip to button
        self.tooltip = Tooltip(self.button, 'This is a tooltip')

The tooltip will automatically be shown while hovering the widget. If you want to manually show and hide the tooltip, you can use the show() and hide() methods:

tooltip.show()
tooltip.hide()

To delete a tooltip, you can use the deleteLater() method:

tooltip.deleteLater()

To get notified when a tooltip gets shown or hidden, you can subscribe to the shown and hidden signals:

tooltip.shown.connect(lambda: print('shown'))
tooltip.hidden.connect(lambda: print('hidden'))

Customization

• Setting the widget:

tooltip.setWidget(widget)  # Default: None

• Setting the text:

tooltip.setText('Text of the tooltip')  # Default: ''

• Setting the placement:

tooltip.setPlacement(TooltipPlacement.RIGHT)  # Default: TooltipPlacement.AUTO

AVAILABLE PLACEMENTS:
AUTO, LEFT, RIGHT, TOP, BOTTOM

• Setting the fallback placements:

tooltip.setFallbackPlacements([TooltipPlacement.TOP, TooltipPlacement.BOTTOM])  # Default: []

If the tooltip doesn't fit on the screen with the primary placement, one of the fallback placements will be chosen instead in the order of the provided list.
To get the current placement of the tooltip, you can use the getActualPlacement() method.

• Enabling or disabling the triangle:

tooltip.setTriangleEnabled(False)  # Default: True

• Setting the size of the triangle:

tooltip.setTriangleSize(7)  # Default: 5

• Setting a duration:

tooltip.setDuration(1000)  # Default: 0

The duration is the time in milliseconds after which the tooltip will start fading out again. If the duration is set to 0, the tooltip will stay visible for as long as the widget is hovered.

• Setting the offsets:

# Setting the offset for a specific placement
tooltip.setOffsetByPlacement(TooltipPlacement.LEFT, QPoint(-10, 5))

# Using a dict that specifies the offset for each placement you want to set
offsets = {
    TooltipPlacement.LEFT:   QPoint(-10, 5),
    TooltipPlacement.RIGHT:  QPoint(10, 5),
    TooltipPlacement.TOP:    QPoint(5, -10),
    TooltipPlacement.BOTTOM: QPoint(5, 10)
}
tooltip.setOffsets(offsets)

# Setting the offsets for all the placements to a single value
tooltip.setOffsetsAll(QPoint(10, 5))

Each placement / side has its own offset to allow for full customizability. Each offset is a QPoint, which is made up of an x and y value.
By default, all the offsets are set to QPoint(0, 0).

• Adding delays to the fade in / out animations after hovering the widget:

tooltip.setShowDelay(500)  # Default: 50
tooltip.setHideDelay(500)  # Default: 50

• Setting the durations of the fade in / out animations:

tooltip.setFadeInDuration(250)   # Default: 150
tooltip.setFadeOutDuration(250)  # Default: 150

• Setting the border radius:

tooltip.setBorderRadius(0)   # Default: 2

• Enabling or disabling the border:

tooltip.setBorderEnabled(True)   # Default: False

• Setting custom colors:

tooltip.setBackgroundColor(QColor('#FCBA03'))   # Default: QColor('#111214')
tooltip.setTextColor(QColor('#000000'))         # Default: QColor('#CFD2D5')
tooltip.setBorderColor(QColor('#A38329'))       # Default: QColor('#403E41')

• Setting a custom font:

tooltip.setFont(QFont('Consolas', 10))  # Default: QFont('Arial', 9, QFont.Weight.Bold)

• Applying margins to the content of the tooltip:

tooltip.setMargins(QMargins(10, 8, 10, 8))  # Default: QMargins(12, 8, 12, 7)

• Setting a maximum width:

tooltip.setMaximumWidth(150)  # Default: 16777215 (QWIDGETSIZE_MAX)

• Enabling or disabling text centering for wrapped text:

tooltip.setTextCenteringEnabled(False)  # Default: True

• Enabling or disabling the drop shadow:

tooltip.setDropShadowEnabled(False)  # Default: True

• Changing the drop shadow strength:

tooltip.setDropShadowStrength(3.5)  # Default: 2.0

• Making the tooltip translucent:

tooltip.setOpacity(0.8)  # Default: 1.0

Other customization options:

Option	Description	Default
setShowingOnDisabled()	Whether the tooltips should also be shown on disabled widgets	False
setFadeInEasingCurve()	The easing curve of the fade in animation	QEasingCurve.Type.Linear
setFadeOutEasingCurve()	The easing curve of the fade out animation	QEasingCurve.Type.Linear
setMarginLeft()	Set left margin individually	12
setMarginRight()	Set right margin individually	12
setMarginTop()	Set top margin individually	8
setMarginBottom()	Set bottom margin individually	7
