Android "PlainTextField UI Problem"

[ademmler]

Hi there,

I have a strange Problem, which appears only on Android my Android device with Android Version 14.
When I test the code on iOS or MAcIntel everything works as expected. Qt 6.7 with build Plattform android-34.

I am creating a small app, which takes a text and uses text2speech in order to speak this text.
Because this app is ment for handicaped people I created my own minimal keyboard layout.
When I type a text it becames visibel after 4 characters had been typed - not before.

// Create QButtons for letters A to Z    
    for (int i = 0; i < 26; ++i) {

        char nMyChar = static_cast<char>('A' + i);
        QChar letter = char(nMyChar);
        QPushButton *button = new QPushButton(letter);
        //button->setFixedSize(buttonSize);
        button->setSizePolicy(QSizePolicy::MinimumExpanding, QSizePolicy::MinimumExpanding);
        button->setFont(customFont);
        layout->addWidget(button, i / 10, i % 10);

        connect(button, &QPushButton::clicked, this, &MyTalker::onButtonClicked);
    }

void MyTalker::onButtonClicked()
{
    QPushButton *clickedButton = qobject_cast<QPushButton *>(sender());

    if (clickedButton &&
        clickedButton->objectName() != "pushButtonClear" &&
        clickedButton->objectName() != "pushButtonSpace") {

        QString buttonText = clickedButton->text();
        QString currentText = textField->toPlainText();
        textField->setPlainText(currentText + buttonText);
    }
}
