PyQT5 - How to use QCompleter, QGIS Plugin

[bemlun]

I'm trying to use QCompleter to get something like in the image. The code seems pretty simple, but in my dialog nothing happens. Is there some problem in this code? The dialog is created using Qt Designer.

import sys
from PyQt5.QtWidgets import QAction, QFileDialog, QApplication, QWidget, QVBoxLayout, QLineEdit, QCompleter

#

def run(self):
  if self.first_start == True:
    self.first_start = False
    self.dlg = SelectFeatureDialog()

    strList = ['Python', 'PyQt5', 'Qt', 'QML']   
    completer = QCompleter(strList)
    self.dlg.lineEdit.setCompleter(completer)  

  self.dlg.show()
  result = self.dlg.exec_()
  if result:
    pass

EDIT: are there some errors in these settings?

Hi,

This example works as expected:

import sys

from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import QApplication, QLineEdit, QCompleter, QDialog, QVBoxLayout

if __name__ == "__main__":
    app = QApplication(sys.argv)
    line_edit = QLineEdit()
    completer = QCompleter(["Apple", "Alps"])
    completer.setCaseSensitivity(Qt.CaseInsensitive)
    line_edit.setCompleter(completer)
    dialog = QDialog()
    layout = QVBoxLayout(dialog)
    layout.addWidget(line_edit)
    dialog.show()
    sys.exit(app.exec_())

What version of PyQt5 are you using ?
