based on the fact that the crash never seemed to have happened with default screen resolutions and also inspired by the only other getmem usage in the code I came up with this simple solution which seems to work just fine.
I do not understand why getmem seems to need this, but well - feel free to explain.
#include "themesmodel.h"
ThemesModel::ThemesModel(QStringList themes, QObject *parent) :
QAbstractListModel(parent)
{
#if QT_VERSION >= QT_VERSION_CHECK(4, 7, 0)
m_data.reserve(themes.size());
#endif
foreach(QString theme, themes)
{
m_data.append(QHash<int, QVariant>());
m_data.last().insert(Qt::DisplayRole, theme);
}
}
int ThemesModel::rowCount(const QModelIndex &parent) const
{
if(parent.isValid())
return 0;
else
return m_data.size();
}
QVariant ThemesModel::data(const QModelIndex &index, int role) const
{
if(index.column() > 0 || index.row() >= m_data.size())
return QVariant();
else
return m_data.at(index.row()).value(role);
}
bool ThemesModel::setData(const QModelIndex &index, const QVariant &value, int role)
{
if(index.column() > 0 || index.row() >= m_data.size())
return false;
else
{
m_data[index.row()].insert(role, value);
return true;
}
}
