PyQt6基础_界面控件简单介绍III

前置： 

QDateEdit 、QDateTimeEdit

QTableWidget

前置： 

1 本系列将以 “PyQt6基础_”开头，放在【PyQt6基础】专栏
2 本文只将界面控件简单讲述，后续博文会对一些控件进一步讲解，会统一放在这个系列里
3 本系列后续会在B站录制视频，到时会在文末贴出链接。本人还是建议先看博文，不懂的再看视频，这样效率高，节约时间。

注意：以下链接虽然是PySide6的官方文档，但PyQt6大部分都通用。

QDateEdit 、QDateTimeEdit

https://doc.qt.io/qtforpython-6/PySide6/QtWidgets/QDateTimeEdit.html  QDateTimeEdit官方文档

from PyQt6.QtCore import Qt,QSize,QDate,QDateTime
from PyQt6.QtWidgets import (
QApplication,QWidget,QPushButton,QMainWindow,QLabel,QHBoxLayout,QVBoxLayout,QLineEdit,QMessageBox,
QDateEdit,QDateTimeEdit
 )

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('PyQt6基础')
        self.setMinimumSize(QSize(600,400))

        self.dateedit = QDateEdit()
        self.dateedit.setDate(QDate(2025,1,1))
        self.dateedit.setDisplayFormat('yyyy-MM-dd')
        self.dateedit.userDateChanged.connect(self.dateedit_userDateChanged)
        self.label1 = QLabel()
        self.datetimeedit = QDateTimeEdit()
        self.datetimeedit.setDateTime(QDateTime(2025,1,1,0,0,0))
        self.datetimeedit.setDisplayFormat('yyyy-MM-dd HH:MM:ss')
        self.datetimeedit.dateTimeChanged.connect(self.datetimeedit_dateTimeChanged)
        self.label2 = QLabel()

        layout = QVBoxLayout()
        layout.addWidget(self.dateedit)
        layout.addWidget(self.label1)
        layout.addWidget(self.datetimeedit)
        layout.addWidget(self.label2)

        widget = QWidget()
        widget.setLayout(layout)
        self.setCentralWidget(widget)
        pass
    def dateedit_userDateChanged(self,a0:QDate):
        self.label1.setText(a0.toString('yyyy-MM-dd'))
        pass
    def datetimeedit_dateTimeChanged(self,a0:QDateTime):
        self.label2.setText(a0.toString('yyyy-MM-dd HH:MM:ss'))
        pass



if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec()
    pass

1 这两个控件的操作涉及QDate、QDateTime 两个数据对象，需要了解下才能处理QDateEdit和QDateTimeEdit 日期和时间的获取和放置
