Я пытаюсь создать QCompleter, который отлично работает, если я просто собираю QLineEdit.
Однако если я уроню QLineEdit в QMainWindow, QCompleter больше не будет работать.
Вот класс LineEdit
# LineEdit class
import sys
from PyQt4 import QtCore, QtGui
class LineEdit(QtGui.QLineEdit):
def __init__(self, parent=None):
super(LineEdit, self).__init__(parent)
self.setFocusPolicy(QtCore.Qt.StrongFocus)
self.completer = QtGui.QCompleter(self)
self.completer.setCompletionMode(QtGui.QCompleter.UnfilteredPopupCompletion)
self.pFilterModel = QtGui.QSortFilterProxyModel(self)
self.pFilterModel.setFilterCaseSensitivity(QtCore.Qt.CaseInsensitive)
self.completer.setPopup(self.view())
self.setCompleter(self.completer)
self.textEdited[unicode].connect(self.pFilterModel.setFilterFixedString)
def setModel(self, model):
self.pFilterModel.setSourceModel(model)
self.completer.setModel(self.pFilterModel)
def setModelColumn( self, column ):
self.completer.setCompletionColumn(column)
self.pFilterModel.setFilterKeyColumn(column)
def view(self):
return self.completer.popup()
def index( self ):
return self.currentIndex()
QCompleter работает, если я собираю LinEdit таким образом
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
model = QtGui.QStandardItemModel()
for i,word in enumerate(['test', 'blah', 'heh', 'yep']):
item = QtGui.QStandardItem(word)
model.setItem(i, 0, item)
lineEdit = LineEdit()
lineEdit.setModel(model)
lineEdit.setModelColumn(0)
lineEdit.show()
sys.exit(app.exec_())
Это прекрасно компилируется, но больше не показывает QCompleter
if __name__ == '__main__':
class Example(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.centralWidget = QtGui.QWidget(self)
self.layout = QtGui.QVBoxLayout(self.centralWidget)
# can I push this inside the LineEdit class instead?
model = QtGui.QStandardItemModel()
for i, word in enumerate(['test', 'blah', 'heh', 'yep', 'hello', 'hi']):
item = QtGui.QStandardItem(word)
model.setItem(i, 0, item)
# Make a LineEdit instance
self.lineEdit = LineEdit(parent=self.centralWidget)
self.lineEdit.setModel(model)
self.lineEdit.setModelColumn(0)
self.layout.addWidget(self.lineEdit)
self.setCentralWidget(self.centralWidget)
app = QtGui.QApplication(sys.argv)
QtWin = Example()
QtWin.show()
sys.exit(app.exec_())
