WAbstractTableModel implementation
Added by Aleksander Fular over 11 years ago
Hello,
First, sorry for this kind of question..
I've been trying for hours just to implement my class extending abstractTableModel class.
Anyone could give me sample how to implement simple TableContainer just to display one or two WText's ?
implementations for
rowCount,
columnCount,
and data().
for example my attempt..
WidgetModel::WidgetModel(void)
{
mElement = new Wt::WText("element");
this->setData(0,0,mElement);
}
same implementation for rowCount as ColumnCount:
int WidgetModel::columnCount(const Wt::WModelIndex &index) const
{
printf("WidgetMode::ColumnCount() Called.\r\n");
if(index.isValid()) or index.internalPointer == 0 ?
return 1;
return 0;
}
data:
boost::any WidgetModel::data(const Wt::WModelIndex &index,int) const
{
printf("WidgetMode::data() Called %d %d.\r\n",index.row(),index.column());
return boost::any(mElement);
}
Any help would be deeply appreciated..

I finally got this.
Key was to just handle role in data function.
boost::any WidgetModel::data(const Wt::WModelIndex &index,int role) const
{
if(role 0)
{
return boost::any(Wt::WString(\"HAIHAIHAI\"));
}
else if(role 3)
{
return boost::any(Wt::WString("aaa NodeWidget"));
}
return boost::any();
}
