PyQt5 QCalendarWidget 设置自定义快捷键到特定月份
在这篇文章中,我们将看到如何为QCalendarWidget设置自定义快捷键来进入特定的月份,例如,当用户按下’O’键时,日历应该显示10月,其他月份也是如此。对于像1月、6月和7月这样的月份,如果它们的首字母相同,那么当’J’键被按下时,它应该是当前月份的下一个月,例如,如果当前月份是6月,’J’键被按下,它应该显示7月,如果当前月份是7月,它应该显示1月。
实施步骤:
1.创建一个主窗口
2.创建一个QCalendarWidget
3.为日历设置各种属性
4.抓住日历的键盘,这样默认的键盘功能就不能发生了
5.覆盖keyPressEvent
6.在覆盖方法中创建一个所有月份的按键列表
7.获取日历的当前月份和年份
8.检查’J’键是否被按下,然后检查当前月份是否是一月,然后将当前月份设置为六月,如果当前月份是六月,则将当前月份设置为七月,否则将当前月份设置为一月
9.如果按下’M’键,则检查当前月份是否为3月,然后将当前月份设为5月,否则将当前月份设为3月
10 同样,如果按下’A’键,则检查当前月份是否为4月,将当前月份设为8月,否则将当前月份设为4月
11.如果任何其他键被按下,检查该键是否存在于月份列表中,然后得到该键在列表中的索引,然后将当前月份设置为索引+1。
