Hola, hemos encontrado la respuesta a tu búsqueda, has scroll y la hallarás aquí.
Solución:
Aquí hay un ejemplo de filtrado en PyQt usando QSortFilterProxyModel, QStandardItemModel y QTableView, se puede adaptar fácilmente a otras vistas y modelos:

from PyQt4 import QtCore, QtGui
class myWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
super(myWindow, self).__init__(parent)

self.gridLayout.addWidget(self.view, 1, 0, 1, 3)
self.gridLayout.addWidget(self.comboBox, 0, 2, 1, 1)
self.gridLayout.addWidget(self.label, 0, 0, 1, 1)
self.setCentralWidget(self.centralwidget)
self.label.setText("Regex Filter")
self.model = QtGui.QStandardItemModel(self)
for rowName in range(3) * 5:
self.model.invisibleRootItem().appendRow(
[ QtGui.QStandardItem("row 0 col 1".format(rowName, column))
for column in range(3)
]
)
self.proxy = QtGui.QSortFilterProxyModel(self)
self.proxy.setSourceModel(self.model)
self.view.setModel(self.proxy)
self.comboBox.addItems(["Column 0".format(x) for x in range(self.model.columnCount())])
self.lineEdit.textChanged.connect(self.on_lineEdit_textChanged)
self.comboBox.currentIndexChanged.connect(self.on_comboBox_currentIndexChanged)
self.horizontalHeader = self.view.horizontalHeader()
self.horizontalHeader.sectionClicked.connect(self.on_view_horizontalHeader_sectionClicked)
@QtCore.pyqtSlot(int)
def on_view_horizontalHeader_sectionClicked(self, logicalIndex):
self.logicalIndex = logicalIndex
self.menuValues = QtGui.QMenu(self)
self.signalMapper = QtCore.QSignalMapper(self)
self.comboBox.blockSignals(True)
self.comboBox.setCurrentIndex(self.logicalIndex)
self.comboBox.blockSignals(True)
valuesUnique = [ self.model.item(row, self.logicalIndex).text()
for row in range(self.model.rowCount())
]
actionAll = QtGui.QAction("All", self)
actionAll.triggered.connect(self.on_actionAll_triggered)
self.menuValues.addAction(actionAll)
self.menuValues.addSeparator()
for actionNumber, actionName in enumerate(sorted(list(set(valuesUnique)))):
action = QtGui.QAction(actionName, self)
self.signalMapper.setMapping(action, actionNumber)
action.triggered.connect(self.signalMapper.map)
self.menuValues.addAction(action)
self.signalMapper.mapped.connect(self.on_signalMapper_mapped)
headerPos = self.view.mapToGlobal(self.horizontalHeader.pos())
posY = headerPos.y() + self.horizontalHeader.height()
posX = headerPos.x() + self.horizontalHeader.sectionPosition(self.logicalIndex)
self.menuValues.exec_(QtCore.QPoint(posX, posY))
@QtCore.pyqtSlot()
def on_actionAll_triggered(self):
filterColumn = self.logicalIndex
filterString = QtCore.QRegExp( "",
QtCore.Qt.CaseInsensitive,
QtCore.QRegExp.RegExp
)
self.proxy.setFilterRegExp(filterString)
self.proxy.setFilterKeyColumn(filterColumn)
@QtCore.pyqtSlot(int)
def on_signalMapper_mapped(self, i):
stringAction = self.signalMapper.mapping(i).text()
filterColumn = self.logicalIndex
filterString = QtCore.QRegExp( stringAction,
QtCore.Qt.CaseSensitive,
QtCore.QRegExp.FixedString
)
self.proxy.setFilterRegExp(filterString)
self.proxy.setFilterKeyColumn(filterColumn)
@QtCore.pyqtSlot(str)
def on_lineEdit_textChanged(self, text):
search = QtCore.QRegExp( text,
QtCore.Qt.CaseInsensitive,
QtCore.QRegExp.RegExp
)
self.proxy.setFilterRegExp(search)
@QtCore.pyqtSlot(int)
def on_comboBox_currentIndexChanged(self, index):
self.proxy.setFilterKeyColumn(index)
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
main = myWindow()
main.show()
main.resize(400, 600)
sys.exit(app.exec_())
Para obtener los resultados requeridos, se abre un menú emergente haciendo clic en el encabezado y se completa con los valores únicos para esa columna. Una vez que se selecciona un elemento en el menú emergente, el valor se pasa a self.proxy.setFilterRegExp(filterString) y la columna a self.proxy.setFilterKeyColumn(filterValue).
