Qt getting nearby widgets of type around a widget?

Question

I am trying to stack rectangular widgets one after another over a line edit and for each one, I need to know the position of the one to the left, so I can push the new one to the right, so they are next to each other instead of one over another. Is there a way to get a widget of the same type next to another widget, so I can check its coordinates and size and move the new one to the right respectively?

If they are top-level widgets, there is. But if not, you'll need to tag them somehow and then search for them. Check for these function in QApplication :

QWidget *   topLevelAt(const QPoint & point)
QWidget *   topLevelAt(int x, int y)
QWidgetList topLevelWidgets()

and in QObject (from which QWidget inherits):

T   findChild(const QString & name = QString()) const
QList<T>    findChildren(const QString & name = QString()) const
QList<T>    findChildren(const QRegExp & regExp) const
