I am now using QTextEdit with qt virtual keyboard, and I face an issue with QTextEdit

I want to disable the textcursor in QTextEdit. I tried to use

setCursorWidth(0);

The textcursor does disappear. But when I use arabic keybaord, there will be a small arrow blinking up there

like this:

Is there any way to disable that blinking cursor?
thanks a lot!

Actually this is a Qt bug which is reported here. As a workaround you can have your custom class which inherits from QTextEdit and re-implement keyPressEvent event:

class TextEdit : public QTextEdit

public:
 TextEdit(QWidget* parent = nullptr) : QTextEdit(parent) 
 setReadOnly(true);
 
 void keyPressEvent(QKeyEvent* event) 
 setReadOnly(false);
 QTextEdit::keyPressEvent(event);
 setReadOnly(true);
 
;

This will also hide the cursor in Right to left languages.

 int pixelMetric(QStyle::PixelMetric metric, const QStyleOption *option = nullptr, const QWidget *widget = nullptr) const override
 
 if(metric == PM_TextCursorWidth)
 return 0;
 return QProxyStyle::pixelMetric(metric, option, widget);
 
;


int main(int argc, char *argv[])

 QApplication a(argc, argv);
 CursorStyle *style = new CursorStyle(a.style());
 a.setStyle(style);
 QWidget w;
 QVBoxLayout *lay = new QVBoxLayout(&w);
 lay->addWidget(new QLineEdit);
 lay->addWidget(new QTextEdit);
 w.show();
 return a.exec();
