Visual studio has a mouseover error on the indirection operator on line 13 of the example: "Error: no instance of function template "QObject::findChild" matches the argument list." What am I doing wrong? -
Hi,
findChild is a template function so you have to give the type of the child you are searching.
In your case:
@ grid = Root->findChild<QObject *>("theGrid", Qt::FindDirectChildrenOnly);@
