translating qt3 querylist to qt4

This should work:

foreach( CustomLineEdit *obj, MyTabPage->findChildren< CustomLineEdit * >( QRegExp( "leHS.*" ) ) ) {
   qDebug() << "  Connecting" << obj->objectName();
   connect( obj, SIGNAL(NumberChanged(double)), SLOT(CalcProceeds()) );
}

foreach( CustomLineEdit *obj, MyTabPage->findChildren< CustomLineEdit * >( QRegExp( "leHS.*" ) ) ) {
   qDebug() << "  Connecting" << obj->objectName();
   connect( obj, SIGNAL(NumberChanged(double)), SLOT(CalcProceeds()) );
}

To copy to clipboard, switch view to plain text mode 

Replace CustomLineEdit with your custom line edit's class name.

This looks really good, and quite a difference in structure. Does this find all children & grandchildren, or just children? From my understanding, findChildren finds all, but I only wanted the direct children.

Thanks for pointing out the "foreach" addition as well, I hadn't known about that.

Thanks for the help!

According to the docs the search is recursive and it seems that there is no other way than:

if( obj->parent() == MyTabPage ) {
   ...
}

if( obj->parent() == MyTabPage ) {
   ...
}

I was afraid of that.
