Hi~How can I get column number in a line??I used QTextCursor movePositions(QTextCursor::Left),movePositions(QTe xtCursor::Right).But there comes a problem!
when i press left button , the return value of movePositions(QTextCursor::Right) is true.
my code is
void textEdit::keyPressEvent(QKeyEvent *e)
{
QTextCursor cursor = textEdit->textCursor();
if(movePositions(QTextCursor::Left))
column_num_--;
if(movePositions(QTextCursor::Right))
column_num_++;
}

Shouldn't your code be something like

Qt Code:

Switch view

void textEdit::keyPressEvent(QKeyEvent *e)
{
     QTextCursor cursor = textEdit->textCursor();
     if(e->key() == Qt::Key_Left){
           if(movePositions(QTextCursor::Left)){
              column_num_--;
           }
     }
     else if(e->key() == Qt::Key_Right){
             if(movePositions(QTextCursor::Right)){
                    column_num_++;
             }
      }
}

void textEdit::keyPressEvent(QKeyEvent *e)
{
     QTextCursor cursor = textEdit->textCursor();
     if(e->key() == Qt::Key_Left){
           if(movePositions(QTextCursor::Left)){
              column_num_--;
           }
     }
     else if(e->key() == Qt::Key_Right){
             if(movePositions(QTextCursor::Right)){
                    column_num_++;
             }
      }
}
