        <mike

import sys
from qt import *
from qttable import *

class Float_Field(QTableItem):

    def __init__(self, table, data):
        print "Creating float field."
        QTableItem.__init__(self, table, QTableItem.OnTyping, str(data))

    def createEditor(self):
        print "createEditor"
        editor = QLineEdit(self.text(), self.table().viewport())
        self.connect(editor, SIGNAL("textChanged(QString &)"),
                     self.table(), SLOT("doValueChanged"))
        editor.setValidator(QDoubleValidator(self))
        return editor


app = QApplication(sys.argv)
table = QTable(1, 1)
table.setItem(1, 1, Float_Field(table, "12.34"))
app.setMainWidget(table)
table.show()
app.exec_loop()
