我正在PyQt5和Qt Designer中使用QTableWidget创建数据条目表。我想要的是一种简单的方法,使“ Enter” keyPressEvent像按Tab键一样在表中移动。以下代码捕获Enter键按下事件。如何使其移动光标?
def keyPressEvent(self, ev):
if ev.key() in (QtCore.Qt.Key_Return, QtCore.Qt.Key_Enter):
print("Enter key pressed")
答案 0 :(得分:2)
应该使用keyPressEvent
+ QShortcut
,而不是使用较低级别的focusNextPrevChild()
,如下所示:
import sys
from PyQt5 import QtCore, QtWidgets
from functools import partial
class Widget(QtWidgets.QWidget):
def __init__(self, parent=None):
super(Widget, self).__init__(parent)
self.tableWidget = QtWidgets.QTableWidget()
self.tableWidget.setRowCount(4)
self.tableWidget.setColumnCount(2)
for i in range(self.tableWidget.rowCount()):
for j in range(self.tableWidget.columnCount()):
it = QtWidgets.QTableWidgetItem("Cell {}{}".format(i, j))
self.tableWidget.setItem(i, j, it)
self.layout = QtWidgets.QVBoxLayout(self)
self.layout.addWidget(self.tableWidget)
for key in (QtCore.Qt.Key_Return, QtCore.Qt.Key_Enter):
QtWidgets.QShortcut(key, self.tableWidget, partial(self.tableWidget.focusNextPrevChild, True))
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
ex = Widget()
ex.show()
sys.exit(app.exec_())
