以奇怪的形式顯示的數字類型

我使用的是PyQt + Qt Designer，並將它連接到我的PostgreSQL數據庫。當我嘗試從我這個代碼數據庫顯示記錄：以奇怪的形式顯示的數字類型

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()

數字列是這樣的：2.3177e + 09，而他們應該像他們在我的數據庫，它是這樣看：2317698765.這一直工作得很好，直到我將（PostgreSQL內部）列類型從字符（11）更改爲數字（11,0）（這是我要求的）。有沒有辦法讓這些列以正常方式顯示價值，而不是這個奇怪的方式？

編輯：

我已經把是否列== 0（原因這就是怪異價值，而且在最後一列，第4列）。它完全刪除我的第一列（列0），它修復了最後一列（4列），所以它看起來很好，它給了我很多的錯誤行：

您可以使用QItemDelegate來格式化您的數據。

短期數據中的列索引解釋

集委託（在這種情況下，2），並把它放在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()

龍解釋（推薦閱讀本文）

1）首先，您需要知道您的列中的格式數據。這是我的數據示例;

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

OK，我想告訴整數格式的第3列。

2沒有指數格式）在指定的列索引設置你的格式。這種情況是在QItemDelegate.paint (self, QPainter painter, QStyleOptionViewItem option, QModelIndex index)中實現的第3列到整數格式。此外，您可以自定義您想要的格式，例如xxxx.xx $等。在這種情況下，轉換爲字符串以便顯示整數。

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）把你QCustomDelegate在QAbstractItemView您QtGui.QTableView或子類的方法QAbstractItemView.setItemDelegate (self, QAbstractItemDelegate delegate)。喜歡這個;

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

最後，數據應該是這樣的;

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

示例;

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_())

我修改了我的帖子。 – Luka 2014-09-06 10:46:23

'indexQModelIndex.model（）.method（indexQModelIndex，QtCore.Qt.EditRole）'的Meybe返回值是float數據類型（不是'QVariant'）。好的，把它轉換成字符串。檢查我的編輯帖子。我有問題，你的PyQt版本是什麼？謝謝。 – 2014-09-06 17:36:39

它現在正在工作！你是拯救者，再一次:)。我使用PyQt4，這個版本：PyQt4-4.11.1-gpl-Py3.4-Qt4.8.6-x64.exe。讓我再問你一件事。我已經把如果列== 2，並且它適用於我所有的數字列，爲什麼？例如，它適用於我的ID列（第0列）和我的電話號碼列（第4列）？ – Luka 2014-09-06 21:28:23

以奇怪的形式顯示的數字類型
