我正在使用PyQt5制作一個應(yīng)用程序，并面臨一些麻煩。我想通過按 輸入 鍵從QTable視圖中選擇數(shù)據(jù)，并將其顯示在QLine編輯中。我已經(jīng)用雙擊信號做了這些事情，但我仍然想通過兩種方式向QLineEdit顯示數(shù)據(jù)，然后在按輸入鍵或雙擊后立即關(guān)閉QTableView對話框。這是我的代碼：import sys import osfrom PyQt5 import QtCore, QtGui, QtWidgets, uicclass Application(QtWidgets.QMainWindow): def __init__(self): super(Application, self).__init__() self.mainwindow = uic.loadUi('test.ui', self) self.mainwindow.pushButton.clicked.connect(self.table) def table(self): self.table = QtWidgets.QTableView() data = [ [2, 3, 5], [23, 4, 5], [2, 6, 7], [0, 3, 5] ] self.model = TableModel(data) self.table.setModel(self.model) self.table.doubleClicked.connect(self.on_click) self.table.show() def on_click(self, signal): row = signal.row() # RETRIEVES ROW OF CELL THAT WAS DOUBLE CLICKED column = signal.column() # RETRIEVES COLUMN OF CELL THAT WAS DOUBLE CLICKED cell_dict = self.model.itemData(signal) # RETURNS DICT VALUE OF SIGNAL cell_value = cell_dict.get(0) # RETRIEVE VALUE FROM DICT index = signal.sibling(row, 0) index_dict = self.model.itemData(index) index_value = index_dict.get(0) print( 'Row {}, Column {} clicked - value: {}\n'.format(row, column, cell_value)) self.mainwindow.lineEdit.setText('%s' %cell_value)class TableModel(QtCore.QAbstractTableModel): def __init__(self, data): super(TableModel, self).__init__() self._data = data def data(self, index, role): if role == QtCore.Qt.DisplayRole: return self._data[index.row()][index.column()] def rowCount(self, index): return len(self._data) def columnCount(self, index): return len(self._data[0])if __name__ == '__main__': application = QtWidgets.QApplication(sys.argv) window = Application() window.show() application.exec_()還有我的桂：讓我解釋一下：當(dāng)點(diǎn)擊按鈕時，它會顯示一個數(shù)據(jù)表，然后我想通過按Enter鍵選擇表中的數(shù)據(jù)，之后它將顯示數(shù)據(jù)到QlineEdit并關(guān)閉表

其邏輯是檢測按鍵，例如使用事件過濾器，然后獲取所選元素的 QModel 索引：
class Application(QtWidgets.QMainWindow):
def __init__(self):
super(Application, self).__init__()
uic.loadUi("test.ui", self)
self.pushButton.clicked.connect(self.table)
self.table = QtWidgets.QTableView()
self.table.doubleClicked.connect(self.write_text)
self.table.installEventFilter(self)
def table(self):
data = [[2, 3, 5], [23, 4, 5], [2, 6, 7], [0, 3, 5]]
self.model = TableModel(data)
self.table.setModel(self.model)
self.table.show()
def write_text(self, index):
row, column, cell_value = index.row(), index.column(), index.data()
print("Row {}, Column {} clicked - value: {}".format(row, column, cell_value))
self.lineEdit.setText("%s" % cell_value)
self.table.close()
def eventFilter(self, obj, event):
if obj is self.table and event.type() == QtCore.QEvent.KeyPress:
if event.key() in (QtCore.Qt.Key_Return, QtCore.Qt.Key_Enter):
indexes = self.table.selectedIndexes()
if indexes:
self.write_text(indexes[0])
return super(Application, self).eventFilter(obj, event)
