[PyQt] Master-detail relationship with plain QTableView tables (no SQL database)

[Vadym Honcharuk]

thanks a lot, Mark!

I made the following things:

from MainForm

self.connect(self.ui.srcTable.selectionModel(),
QtCore.SIGNAL("currentRowChanged(QModelIndex, QModelIndex)"),
self.frmTableFilter)

further:

 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
	    filterFrmTable.setSourceModel(self.frmTableModel)
	    self.ui.frmTable.setModel(filterFrmTable)
	
	    filterFrmTable.setDynamicSortFilter(True)
            filterFrmTable.setFilterKeyColumn(0)
            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,
-vadym
