There are many settings available for notifications in Meilix like position, size, timeout which can be modified with help of the notifications settings available in LXQT.

Theming Notifications

We will start by creating a file in /usr/share/lxqt/themes for creating a qss file of the notification theme as lxqt-notificationd.qss. This file tells the LXQT about what the colors, size, border, etc. are for a notification.

We start with notifications in this file. We can define color of the text of notifications. It supports alpha values too, but making text transparent decrease.

Notification {
    color: #313639;
    border: 1px solid rgba(155, 155, 155, 00%);
    background:rgba(240, 240, 240, 00%);
    margin: 0px;
    border-radius: 5px;
}

We can add a custom close button also we just need to add the path of the button in the qss file.

#closeButton {
    margin: 3px;
    border-radius: 4px;
    border: 1px solid transparent;
    padding: 4px;
    qproperty-icon: url(lxqt-notificationd/window-close.svg);
}

Other properties like hover on close button for animations can be used like.

#closeButton:hover {
    color: rgba(54, 54, 54, 100%);
    background: rgba(30, 145, 255, 30%);
    border: 1px solid rgba(30, 145, 255, 100%);
}

We can also define custom font, background like an image file, or actions like click, hover etc.

For other notification settings we can create a configuration file notifications.config which we can place in root  or in ~/.config depending upon application weather we want to apply it system wide or only for user.

The configuration file for disabling the sounds in LXQT:

[Sounds]
No sound=true

Settings can also be changed using the menu and they are saved in .config/lxqt/notifications.conf. We have changed the spacing to zero in Meilix so that the notifications are invisible and do not disturb during an event (instead of disabling it in case someone wants notifications they can change the spacing).

[General]
spacing=0
