PyQt5 QCalendarWidget – 工具按钮的背景颜色
在这篇文章中,我们将看到如何为QCalendarWidget的工具按钮设置背景颜色。工具按钮是在顶部可用的按钮,也就是进入左右页面的按钮,给QCalendarWidget设置边框不像给其他小部件设置背景色,日历是小部件,它有很多孩子,也就是组件,我们也可以给独立组件设置背景色。下面是在工具按钮上设置背景色的日历看起来是怎样的
为了做到这一点,我们将使用QCalendarWidget对象的setStyleSheet方法,下面是样式表的代码
QCalendarWidget QToolButton
{
background-color : lightgreen;
}
QCalendarWidget QToolButton::hover
{
background-color : cyan;
}
QCalendarWidget QToolButton::pressed
{
background-color : red;
}
注意: 我们使用QToolButton::hover和QToolButton::pressed来添加边框,只有当鼠标悬停在它们上面或它们被按下时,也有!hover和!pressed,这与hover和pressed状态完全相反。
下面是实现的过程
