subclass QLineEdit to have an index

[nlgootee]

What does the class do with the index number?

Cheers,

The class doesn't do anything with the index. I have a routine that creates a grid consisting of rows with a textbox followed by some labels. They are created in code using a series of for loops. If I can create a subclassed LineEdit(index) I will be able to use an existing routine written in VB6.

Sounds to me like you are confusing how your program keeps track of multiple QLineEdit instances with the QLineEdit instances themselves. If you simply stick the QLineEdit pointers into a vector as you create them, then the index in the vector -is- the index of the QLineEdit. If all of your QLineEdit instances are connected to the same slot, then you can use the QObject::sender() method in the slot to get the pointer to the specific QLineEdit instance that sent the signal, and then search the vector to get the index.

Or if your "index" is non-sequential, you can make a QMap< QWidget *, int > to map the QLineEdit pointer to any integer.

Or you can use QSignalMapper to associate each QLineEdit instance with an integer.

There are lots of ways to do what I think you are trying to do without having to make a custom widget.

Thanks for the reply. I don't understand what you said so it doesn't help much. What is a vector? I appreciate the different methods to do what you think that I want to do, but what I really want is to know if it is possible to subclass a QLineEdit with an index and access it in this format: LineEdit(index) not LineEdit.index
