Qt Toast

C++ port of the pyqttoast library (v1.2.0) - a fully customizable and modern toast notification library for Qt

Features

• Supports showing multiple toasts at the same time
• Supports queueing of toasts
• Supports 7 different positions
• Supports multiple screens
• Modern and fully customizable UI

Usage

Include the Toast.h file, instantiate the Toast, and show the toast notification with the show() method:

Toast* toast = new Toast(this);
toast->setDuration(8000);  // Hide after 8 seconds
toast->setTitle("Error! Cannot complete request.");
toast->setText("Please try again in a few minutes.");
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.

Example

Window.h

#pragma once

#include <QtWidgets/QMainWindow>
#include <QtWidgets/QPushButton>
#include "Toast.h"


class Window : public QMainWindow
{
    Q_OBJECT

public:
    Window(QWidget* parent = nullptr);

private slots:
    void showToast();

private:
    QPushButton* m_button;
};

Window.cpp

#include "Window.h"


Window::Window(QWidget* parent)
{
    // Add button and connect click event
    m_button = new QPushButton(this);
    m_button->setText("Show toast");
    connect(m_button, SIGNAL(clicked()), this, SLOT(showToast()));
}

void Window::showToast()
{
    // Shows a toast notification every time the button is clicked
    Toast* toast = new Toast(this);
    toast->setDuration(6000);  // Hide after 6 seconds
    toast->setTitle("Success! Confirmation email sent.");
    toast->setText("Check your email to complete signup.");
    toast->applyPreset(ToastPreset::SUCCESS);  // Apply style preset
    toast->show();
}

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 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

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

Toast::setAlwaysOnMainScreen(true);  // Default: false

• 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);


// Or setting a custom icon:
toast->setIcon(QPixmap("path/to/your/icon.png"));

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

• Setting the icon size:

toast->setIconSize(QSize(14, 14));  // Default: QSize(18, 18)

• Enabling or disabling the icon separator:

toast->setShowIconSeparator(false);  // Default: true

• 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->setFadeInDuration(100);   // Default: 250
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

• Setting custom colors:

toast->setBackgroundColor(QColor("#292929"));       // Default: #E7F4F9
toast->setTitleColor(QColor("#FFFFFF"));            // Default: #000000
toast->setTextColor(QColor("#D0D0D0"));             // Default: #5C5C5C
toast->setDurationBarColor(QColor("#3E9141"));      // Default: #5C5C5C
toast->setIconColor(QColor("#3E9141"));             // Default: #5C5C5C
toast->setIconSeparatorColor(QColor("#585858"));    // Default: #D9D9D9
toast->setCloseButtonIconColor(QColor("#C9C9C9"));  // Default: #000000

• Setting custom fonts:

toast->setTitleFont(QFont("Times", 10, QFont::Weight::Bold));
toast->setTextFont(QFont("Times", 10);

• 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));
