Hi
Maybe you can see how he do here

My KeyPress Event for Key_Left is not working

Qt Enthusiast

case Qt::Key_Left :
  
    QTextEdit::keyPressEvent(e);
    break;

}

This not working

mrjj

@Qt-Enthusiast
Ok.
try
case Qt::Key_Left :
qDebug() << "Left pressed";
QTextEdit::keyPressEvent(e);
break;
}
and see if that part of code is executed.

Qt Enthusiast

yes it working QTextEdit::keyPressEvent(e); not having a effect

mrjj

@Qt-Enthusiast
So the cursor do not move 1 step to the left ?

Qt Enthusiast

Yes it did not work

mrjj

@Qt-Enthusiast

Ok, i tried a test

class MyTextEdit : public QTextEdit {
 public:
  explicit MyTextEdit(QWidget* parent = 0) : QTextEdit(parent) {}
 protected:
  virtual void keyPressEvent(QKeyEvent* event) override {
    QTextEdit::keyPressEvent( event);
  }
};

and it does work as expected. cursor moves left.

btw in topic title you talk about QTextBrowser. You switched to QTextEdit ?

Qt Enthusiast

yes it is QTextBrowser and we are calling QTextEdit::keyPressEvent( event);
is this a problem

mrjj

@Qt-Enthusiast
Could be if QTextBrowser override keypress to do its own stuff. else not.

mrjj

Ah
Just tried a Text Browser. as name implies its read only so it has no cursor to move around
by keypresses. why not use QTextEdit instead if you want user to input things?

Qt Enthusiast

it is because of legacy code

mrjj

@Qt-Enthusiast
Ok. but TextBrowser seems to ignore it since its read only.

class MyTextEdit : public QTextBrowser {
 public:
  explicit MyTextEdit(QWidget* parent = 0) : QTextBrowser(parent) {}
 protected:
  virtual void keyPressEvent(QKeyEvent* event) override {
    qDebug() << "HERE";
    QTextBrowser::keyPressEvent( event);
  }
};

KeyPressed is not called since its readOnly.

It does react to
ui->browser->moveCursor(QTextCursor::Left, QTextCursor::MoveAnchor);
ui->browser->textCursor().insertText("1");
but cursor is NOT visible.

Qt Enthusiast

not working in my case in case of QTextEdit

mrjj

@Qt-Enthusiast
not sure it will work very well with QTextBrowser
