inline

Adds a row to the table.

Parameters
rowlist of strings to use for each cell's value in the newly added row
Note
If row is shorter than the number of columns in the table than blank cells will be inserted at the end of the row. If row contains more strings then the number of columns in the table then these extra strings will be ignored.

Parameters
attributeMapslist of QgsAttributeMaps where the cell text will be stored
Returns
true if attribute values were successfully set from table's text
Note
not available in python bindings

Reimplemented from QgsComposerTable.

bool QgsComposerTextTable::readXML ( const QDomElement &  itemElem,
const QDomDocument &  doc
