PyQt5 QCalendarWidget - Background Color of the Next Month button

In this article we will see how we can set background color to the next month button of the QCalendarWidget. Next month button is on the right hand size in the tool buttons, tool buttons are the buttons available at the top i.e buttons to go to left and right page, setting background color to QCalendarWidget is not like setting background color to the other widgets, calendar is widget which has many child i.e component we can set border to independent component as well. We can set background color to the tool buttons with the help of QCalendarWidget QToolButton as class name in the style sheet, but this will set background color to all the elements of the tool buttons. In order to do this we will use setStyleSheet method with the QCalendarWidget object, below is the style sheet code

QCalendarWidget QToolButton#qt_calendar_nextmonth
{
background-color : lightgreen;
}
QCalendarWidget QToolButton#qt_calendar_nextmonth::hover
{
background-color : cyan;
}
QCalendarWidget QToolButton#qt_calendar_nextmonth::pressed
{
background-color : red;
}

Note : We use QToolButton#qt_calendar_nextmonth::hover and QToolButton#qt_calendar_nextmonth::pressed to add background color only when mouse hover over them or when they get pressed. There are also !hover and !pressed which are opposite states for the hover and pressed states. Below is the implementation Output :
