[Qt-interest] connect()ing multiple buttons to a receiver

[Malyushytsky, Alex]

You have 2 choices

1) QObject * QObject::sender () const   [protected]

Returns a pointer to the object that sent the signal, if called in a slot activated by a signal; otherwise it returns 0. The pointer is valid only during the execution of the slot that calls this function.
The pointer returned by this function becomes invalid if the sender is destroyed, or if the slot is disconnected from the sender's signal.

2)QSignalMapper.

Best regards,
 Alex

Subject: [Qt-interest] connect()ing multiple buttons to a receiver

To put this simply:

I will have a few buttons (4 or 5) that I want to connect() to a single
receiver.
The receiver will behave slightly differently depending on what button
is pushed though (does the same thing on different data).

The buttons are stored in an array, and are made in a loop.  How many
depends on an
environment variable.  I can connect() them to the receiver just fine,
but as they are in
an array, the receiver doesn't know which one was pushed.

 From what I remember, reimplementing event handlers is a nono.

Cheers
Paul
