As described in the \l{Model Subclassing Reference}, models must
provide implementations for the standard set of model functions:
\l{QAbstractItemModel::}{flags()}, \l{QAbstractItemModel::}{data()},
- \l{QAbstractItemModel::}{headerData()}, and
+ \l{QAbstractItemModel::}{headerData()},
+ \l{QAbstractItemModel::}{columnCount()}, and
\l{QAbstractItemModel::}{rowCount()}. In addition, hierarchical models,
such as this one, need to provide implementations of
\l{QAbstractItemModel::}{index()} and \l{QAbstractItemModel::}{parent()}.
An editable model needs to provide implementations of
\l{QAbstractItemModel::}{setData()} and
- \l{QAbstractItemModel::}{headerData()}, and must return a suitable
+ \l{QAbstractItemModel::}{setHeaderData()}, and must return a suitable
combination of flags from its \l{QAbstractItemModel::}{flags()} function.
Since this example allows the dimensions of the model to be changed,

attribute to the \c qresource tag, specifying a suitable locale
string. For example:
switch (flag) {

- return moreComplexFunction(flag);
+ retVal = moreComplexFunction(flag);
+ break;
case 2:
{
int status = anotherFunction();

Wildcard matching can be convenient because of its simplicity, but
any wildcard regexp can be defined using full regexps, e.g.
- \bold{.*\.html$}. Notice that we can't match both \c .html and \c
+ \bold{.*\\.html$}. Notice that we can't match both \c .html and \c
.htm files with a wildcard unless we use \bold{*.htm*} which will
also match 'test.html.bak'. A full regexp gives us the precision
we need, \bold{.*\\.html?$}.
