数字类型以奇怪的形式显示

我使用PyQt + Qt Designer并将其连接到我的PostgreSQL数据库。当我尝试使用以下代码显示数据库中的记录时：

if self.Kirurg_checkBox.isChecked():
                     Kirurg_query = QSqlQueryModel()
                     Kirurg_query.setQuery("SELECT * FROM kirurg")
                     global view_Kirurg
                     view_Kirurg = QtGui.QTableView()
                     view_Kirurg.setModel(Kirurg_query)
                     view_Kirurg.setWindowTitle('kirurg')
                     view_Kirurg.show()

数字列看起来像这样：2.3177e + 09，虽然看起来像他们看起来像我的数据库，如下所示：2317698765。这个工作正常，直到我改变了（在PostgreSQL内部）列类型中的字符（11）数字（11,0）（这是我的要求）。有没有办法让这些列以正常方式显示价值，而不是这个奇怪的？

修改

如果列== 0，我会把它放在一起（导致奇怪值出现的地方，但最后一列，第4列）。并且它完全删除了我的第一列（第0列），它修复了最后一列（第4列），因此它看起来很漂亮，并且它给了我很多错误行：

您可以使用QItemDelegate格式化数据。

简短说明

在数据列索引中设置委托（在本例中为2）并将其放入QtGui.QTableView 

class QCustomDelegate (QtGui.QItemDelegate):
    def paint (self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex):
        column = indexQModelIndex.column()
        if column == 2:
            textQString = '%.0f' % indexQModelIndex.model().data(indexQModelIndex, QtCore.Qt.EditRole)
            # textQString = indexQModelIndex.model().data(indexQModelIndex, QtCore.Qt.EditRole).toString() # For some version PyQt4-4.11.1-gpl-Py3.4-Qt4.8.6-x64
            self.drawDisplay(painterQPainter, optionQStyleOptionViewItem, optionQStyleOptionViewItem.rect, textQString)
        else:
            QtGui.QItemDelegate.paint(self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex)

和

if self.Kirurg_checkBox.isChecked():
    Kirurg_query = QSqlQueryModel()
    Kirurg_query.setQuery("SELECT * FROM kirurg")
    global view_Kirurg
    view_Kirurg = QtGui.QTableView()
    view_Kirurg.setItemDelegate(QCustomDelegate())
    view_Kirurg.setModel(Kirurg_query)
    view_Kirurg.setWindowTitle('kirurg')
    view_Kirurg.show()

长解释（推荐阅读本文）

1）首先，您需要知道列中的格式数据。这是我的数据示例; 

+------------+------------+-----------------+
|    Name    |   Owner    |      Value      |
+------------+------------+-----------------+
| Sushi      | Lawson     |      2.3177e+12 |
| Yakisoba   | Lawson     |      1.4141e+12 |
| Snack      | 7-11       |      3.1446e+12 |
+------------+------------+-----------------+

好的，我想在第3列显示整数数字格式而不是指数格式。

2）在指定的列索引处设置格式。这种情况是QItemDelegate.paint (self, QPainter painter, QStyleOptionViewItem option, QModelIndex index)中的实现的第3列到整数格式。此外，您可以自定义您想要的格式，例如xxxx.xx $等。在这种情况下，转换为字符串以便于显示整数。

class QCustomDelegate (QtGui.QItemDelegate):
    def paint (self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex):
        column = indexQModelIndex.column()
        if column == 2:
            textQString = indexQModelIndex.model().data(indexQModelIndex, QtCore.Qt.EditRole).toString()
            self.drawDisplay(painterQPainter, optionQStyleOptionViewItem, optionQStyleOptionViewItem.rect, textQString)
        else:
            QtGui.QItemDelegate.paint(self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex)

3）通过方法QAbstractItemView将QCustomDelegate放入QAbstractItemView.setItemDelegate (self, QAbstractItemDelegate delegate)中的QtGui.QTableView或子类。像这样; 

myQTableView = QtGui.QTableView()
myQTableView.setItemDelegate(QCustomDelegate())

最后，数据应该是这样的; 

+------------+------------+-----------------+
|    Name    |   Owner    |      Value      |
+------------+------------+-----------------+
| Sushi      | Lawson     |   2317700000000 |
| Yakisoba   | Lawson     |   1414100000000 |
| Snack      | 7-11       |   3144600000000 |
+------------+------------+-----------------+

实施例

import sys
from PyQt4 import QtCore, QtGui

class QCustomDelegate (QtGui.QItemDelegate):
    def paint (self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex):
        column = indexQModelIndex.column()
        if column == 2:
            textQString = indexQModelIndex.model().data(indexQModelIndex, QtCore.Qt.EditRole).toString()
            self.drawDisplay(painterQPainter, optionQStyleOptionViewItem, optionQStyleOptionViewItem.rect, textQString)
        else:
            QtGui.QItemDelegate.paint(self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex)

class QCustomTreeWidget (QtGui.QTreeWidget):
    def __init__(self, parent = None):
        super(QCustomTreeWidget, self).__init__(parent)
        self.setColumnCount(3)
        self.setItemDelegate(QCustomDelegate())

    def addMenu (self, name, owner, value, parentQTreeWidgetItem = None):
        if parentQTreeWidgetItem == None:
            parentQTreeWidgetItem = self.invisibleRootItem()
        currentQTreeWidgetItem = QtGui.QTreeWidgetItem(parentQTreeWidgetItem)
        currentQTreeWidgetItem.setData(0, QtCore.Qt.EditRole, name)
        currentQTreeWidgetItem.setData(1, QtCore.Qt.EditRole, owner)
        currentQTreeWidgetItem.setData(2, QtCore.Qt.EditRole, value)

myQApplication = QtGui.QApplication([])
myQCustomTreeWidget = QCustomTreeWidget()
myQCustomTreeWidget.addMenu('Sushi',    'Lawson', 2.3177e+012)
myQCustomTreeWidget.addMenu('Yakisoba', 'Lawson', 1.4141e+012)
myQCustomTreeWidget.addMenu('Snack',    '7-11',   3.1446e+012)
myQCustomTreeWidget.show()
sys.exit(myQApplication.exec_())
