Where do you connect the signal ?

[Ketan Shah]

I am trying to connect it through the CheckListItem...
When i Check or uncheck the CheckListItem it should call the stateChange function,which in turn emit the statusChange signal...

What I meant was "show us the code where you make the connection".

for (int i = 0; i < files.size(); ++i)
{

QFileInfo fileInfo = files.at(i);

new Q3CheckListItem(ui->listView,QString("%1").arg(fileInfo.fileName()) , Q3CheckListItem::CheckBox );

}
You are creating new check list items, but you are not connecting the signal, at least not in this part of code. Should be more like:

for (int i = 0; i < files.size(); ++i){
QFileInfo fileInfo = files.at(i);
Q3CheckListItem * item = new Q3CheckListItem(ui->listView,QString("%1").arg(fileInfo.fileName()) , Q3CheckListItem::CheckBox );
connect(item, SIGNAL(...), ...); // figure out the details yourself :)
}
