Body
In the slot that gets called when the signal is emitted you can get the text with <code>QString str = textEdit->toplainText();</code>. Also you can store the previous version of the string and compare to get the character that was added and its position. Regarding the cursor position you can us QTextCurosr class as in this example: widget.h file: <pre><code>#ifndef WIDGET_H #define WIDGET_H #include <QWidget> #include <QTextEdit> #include <QTextCursor> #include <QVBoxLayout> #include <QLabel> class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); private slots: void onTextChanged(); void onCursorPositionChanged(); private: QTextCursor m_cursor; QVBoxLayout m_layout; QTextEdit m_textEdit; QLabel m_label; }; #endif // WIDGET_H </code></pre> widget.cpp file: <pre><code>#include "widget.h" #include <QString> Widget::Widget(QWidget *parent) : QWidget(parent) { connect(&m_textEdit, SIGNAL(textChanged()), this, SLOT(onTextChanged())); connect(&m_textEdit, SIGNAL(cursorPositionChanged()), this, SLOT(onCursorPositionChanged())); m_layout.addWidget(&m_textEdit); m_layout.addWidget(&m_label); setLayout(&m_layout); } Widget::~Widget() { } void Widget::onTextChanged() { // Code that executes on text change here } void Widget::onCursorPositionChanged() { // Code that executes on cursor change here m_cursor = m_textEdit.textCursor(); m_label.setText(QString("Position: %1").arg(m_cursor.positionInBlock())); } </code></pre> main.cpp file: <pre><code>#include <QtGui/QApplication> #include "widget.h" int main(int argc, char *argv[]) { QApplication a(argc, argv); Widget w; w.show(); return a.exec(); } </code></pre>

1. COI'd expect "cursor" refer to the text cursor, which can also be read from the textEdit object.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
