Need advices to add a table in a textarea QML/C++

[JulienB]

Hello,
I want to insert a table in my text editor (markdown).
I can do it with my code but I think it is ugly and surely there is a better way to do it.
I call the method insertTable() in setTableColumns() but it is strange.
I am new in QML can you give me advices.
Is it possible to get the number of rows and columns from QML with just one Q_PROPERTY?

In the C++ part :

    Q_PROPERTY(int tableRows READ tableRows WRITE setTableRows)
    Q_PROPERTY(int tableColumns READ tableColumns WRITE setTableColumns)

int Backend::tableRows()
{
    return m_tableRow;
}

void Backend::setTableRows(int nbrOfRows)
{
    m_tableRow = nbrOfRows;
}

int Backend::tableColumns()
{
    return m_tableColumn;
}

void Backend::setTableColumns(int nbrOfColumns)
{
    m_tableColumn = nbrOfColumns;
    insertTable();
}

void Backend::insertTable()
{
    QTextCursor cursor(textCursor());
    cursor.movePosition(QTextCursor::Start);

    QTextTable *table = cursor.insertTable(tableRows(), tableColumns());
}

In the QML part :

            SpinBox {
                id: tableRows
            }

            SpinBox {
                id: tableColumns
            }

            Button {
                id: closeButton
                text: "Close"
                onClicked: {
                    popup.close()

                    backend.tableRows = tableRows.value
                    backend.tableColumns = tableColumns.value
                }
            }

    ScrollView {
        anchors.fill: parent
        TextArea {
            id: textEdit
            textFormat: TextEdit.MarkdownText
            focus: true
            selectByMouse: true
            persistentSelection: true
        }

Thank you

@JulienB U can return QVariantMap in your c++ function.

hi
@JulienB said in Need advices to add a table in a textarea QML/C++:

if you want to pass value from qml to c++ you can simply create a Q_INVOKABLE method that takes 2 arguments

Q_INVOKABLE void setSize(int r, int c){
...
  QTextTable *table = cursor.insertTable(r ,c);
}

// qml

backend.setSize(tableRows.value , tableColumns.value)

@LeLev Thank you it works perfectly!!
