Inner widget doesn't closes in a modified QFileDialog

[MrAWD]

I am trying to get QFIleDialog to return folders along with files. I have used a code from Stack Overflow example and with some help from this thread it is in usable state. But, when drop box is opened and Enter clicked, drop box stays on the screen. Here is a complete code:

from PySide2.QtWidgets import (QFileDialog, QApplication, QDialog,
                               QStackedWidget, QListView, QLineEdit,
                               QMessageBox, QWidget, QPushButton, QVBoxLayout)
import sys
from PySide2.QtCore import QFileInfo


class Widget(QWidget):

    def __init__(self):
        super().__init__(None)
        self.button = QPushButton("Open")
        self.button.clicked.connect(self.onButtonCLicked)

        self.mainLayout = QVBoxLayout()
        self.mainLayout.addWidget(self.button)
        self.setLayout(self.mainLayout)
        self.resize(300, 100)

    def onButtonCLicked(self):
        openFilesAndDirs(parent=self, caption="Hi")


def openFilesAndDirs(parent=None,
                     caption='',
                     directory='',
                     filters='',
                     initialFilter='',
                     options=None):

    dialog = QFileDialog(parent, windowTitle=caption)
    dialog.setFileMode(dialog.ExistingFile)

    if options:
        dialog.setOptions(options)
    dialog.setOption(dialog.DontUseNativeDialog, True)

    if directory:
        dialog.setDirectory(directory)

    if filters:
        dialog.setNameFilter(filters)
        if initialFilter:
            dialog.selectNameFilter(initialFilter)

    dialog.accept = lambda: QDialog.accept(dialog)

    stackedWidget = dialog.findChild(QStackedWidget)
    dialogItemView = stackedWidget.findChild(QListView)

    def updateText():
        selected = []
        for index in dialogItemView.selectionModel().selectedRows():
            selected.append('{}'.format(index.data()))

        lineEdit = dialog.findChild(QLineEdit)
        lineEdit.blockSignals(True)
        lineEdit.setText(' '.join(selected) if selected else '')
        lineEdit.blockSignals(False)

    dialogItemView.selectionModel().selectionChanged.connect(updateText)

    lineEdit = dialog.findChild(QLineEdit)
    dialog.directoryEntered.connect(lambda: lineEdit.setText(''))

    filePath = ""
    fileExt = ""

    if dialog.exec_() == QDialog.Accepted:

        files = dialog.selectedFiles()
        if len(files) > 0:
            finfo = QFileInfo(files[0])
            filePath = finfo.absoluteFilePath()
            fileExt = finfo.completeSuffix()

    return filePath, fileExt

if __name__ == "__main__":
    app = QApplication(sys.argv)
    w = Widget()
    w.show()
    sys.exit(app.exec_())

When code is executed, when one letter is typed in the edit box popup box appears under the edit widget, and with Down Arrow, one of the entries is selected, it looks like this:

Pressing on Enter key selects and returns selected entry, but drop box stays on the screen:

What could I do here to remove this widget?

It does go away as soon as you click elsewhere, btw.

@MrAWD said in Inner widget doesn't closes in a modified QFileDialog:

I assume this is some part of your dialogItemView because you obviously use a modified QLineEdit there...
Are these all childs of your dialog? If not, they remain open in position when you close the dialog.
They should close/hide together with it

[MrAWD]

@Pl45m4 That is the whole problem. I am using a non native file dialog and don't have a direct access to that code.

If I don't find solution for this, I will have to write that dialog myself...

@MrAWD

How do you handle the view/model?! Is it part of your dialog? Either close it manually by code when your dialog is accepted or make it a child of your dialog if possible.

[MrAWD]

@Pl45m4 That is the whole issue - I am using standard Qt file dialog in a non native mode, and I don't have its implementation code. If I did, we probably wouldn't have to do any of this
