禁止在pyside中的QTableView中复制/粘贴

Question

我QTableView从QSqlQueryModel获取信息并实时显示。问题是，QTableView允许用户从其中一个字段复制和粘贴信息。

    projectModel = QtSql.QSqlQueryModel()
    projectModel.setQuery("select * from queue",self.db)
    self.total_rows = projectModel.rowCount()
    projectModel.setHeaderData(0, QtCore.Qt.Horizontal, 'ID cola')
    projectModel.setHeaderData(1, QtCore.Qt.Horizontal, 'Código')

    self.projectView = QtGui.QTableView()
    self.projectView.setModel(projectModel)
    self.projectView.resizeColumnsToContents()
    self.projectView.horizontalHeader().setStretchLastSection(True)

例如，如何拒绝复制QTableView的内容并将其粘贴到文本编辑器中？

Answer 1

您可以将整个表格设为只读：

    self.projectView.setEditTriggers(QAbstractItemView.NoEditTriggers)

修改：

如果您还想阻止复制单元格，则需要终止相关的键盘快捷键。下面是一些示例代码：

from PySide import QtGui, QtCore

class Window(QtGui.QWidget):
    def __init__(self, rows, columns):
        super(Window, self).__init__()
        self.table = QtGui.QTableView(self)
        model =  QtGui.QStandardItemModel(rows, columns, self.table)
        for row in range(rows):
            for column in range(columns):
                item = QtGui.QStandardItem('(%d, %d)' % (row, column))
                model.setItem(row, column, item)
        self.table.setModel(model)
        self.table.setEditTriggers(QtGui.QAbstractItemView.NoEditTriggers)
        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.table)
        self.table.installEventFilter(self)

    def eventFilter(self, source, event):
        if (source is self.table and
            event.type() == QtCore.QEvent.KeyPress and
            event == QtGui.QKeySequence.Copy):
            return True
        return super(Window, self).eventFilter(source, event)

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window(5, 5)
    window.setGeometry(600, 300, 600, 250)
    window.show()
    sys.exit(app.exec_())
