thanks a lot, Mark!

I made the following things:

from MainForm

QtCore.SIGNAL("currentRowChanged(QModelIndex, QModelIndex)"),


 def frmTableFilter(self):
	index = self.ui.srcTable.currentIndex()
	if index.isValid():

	    row = index.row()
	    srcCode = self.srcTableModel.data(self.srcTableModel.index(row,
SRCCODE)).toString()    # take ID as text what required by QRegExp

	    filterFrmTable = QtGui.QSortFilterProxyModel() # forming model
            regExp = QtCore.QRegExp(srcCode,
QtCore.Qt.CaseInsensitive) # make filter
            filterFrmTable.setFilterRegExp(regExp) # use filter

Seems work correctly and enought simple and shortly but I not sure if
it's right way...

with best regards,
