Can't input non-English characters!!

[ShinSat]

Hi All,

I'm testing the following code on Windows but can't understand why the QLineEdit doesn't accept non-English characters input.
Any ideas?

from PyQt5.QtCore import Qt, QEvent, QRegExp
from PyQt5.QtWidgets import QTabBar, QTabWidget, QApplication, QLineEdit, QWidget
from PyQt5.QtGui import QRegExpValidator

class EditableTabBar(QTabBar):
    def __init__(self, parent):
        QTabBar.__init__(self, parent)
        self._editor = QLineEdit(self)
        self._editor.setWindowFlags(Qt.Popup)
        self._editor.setFocusProxy(self)
        self._editor.editingFinished.connect(self.handleEditingFinished)
        self._editor.installEventFilter(self)

    def eventFilter(self, widget, event):
        if ((event.type() == QEvent.MouseButtonPress and not self._editor.geometry().contains(event.globalPos())) or (event.type() == QEvent.KeyPress and event.key() == Qt.Key_Escape)):
            self._editor.hide()
            return True
        return QTabBar.eventFilter(self, widget, event)

    def mouseDoubleClickEvent(self, event):
        index = self.tabAt(event.pos())
        if index >= 0:
            self.editTab(index)

    def editTab(self, index):
        rect = self.tabRect(index)
        self._editor.setFixedSize(rect.size())
        self._editor.move(self.parent().mapToGlobal(rect.topLeft()))
        self._editor.setText(self.tabText(index))
        if not self._editor.isVisible():
            self._editor.show()

    def handleEditingFinished(self):
        index = self.currentIndex()
        if index >= 0:
            self._editor.hide()
            self.setTabText(index, self._editor.text())

class Window(QTabWidget):
    def __init__(self):
        QTabWidget.__init__(self)
        self.setTabBar(EditableTabBar(self))
        self.addTab(QWidget(self), 'Tab One')
        self.addTab(QWidget(self), 'Tab Two')

if __name__ == '__main__':

    import sys
    app = QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(app.exec_())

Thanks in advance for your help!

Hi,

What are your system specification ?
What version of PyQt ?
What version of Qt ?
Can you reproduce that with a simple QLineEdit ?

[ShinSat]

@SGaist pyqt5.9.1 on windows7. Interrstingly simple qlineedit works on a simplified widget in different app.
I found copy&paste works but key-in not.
Not sure if there is a configuration controlling the behavior...

[ShinSat]

Since QLineEdit works alone on my env, it may be a QTabBar issue???
But until editingFinished singnal fired from QLineEdit , QLineEdit should be responsible for that, right?
Still investigating what's going on, but have no idea for now. :<

What if you remove the event filter ?

[ShinSat]

@SGaist No change. :<

[SGaist]

Can you show an example of non-ascii char that fails ?

Just tested with àüè and such and it worked fine but on macOS.

[ShinSat]

@SGaist Actually, it doesn't fail, just nothing happened when I key in Japanese characters such as あいうえお. Since I can copy&paste the problematic characters, it may be an environment issue(eg. Windows)??

Thanks,
Sat
