I'd propose to use boost::bind:
for(int i = 0; i < numRecords; ++i) {
// Build your table here, including the buttons:
WPushButton *b = new WPushButton("Show Record", this);
b->clicked().connect(boost::bind(&MyClass::showRecordDetails, this, i));
}
void MyClass::showRecordDetails(int recordnumber)
{
// Update other form with information from 'recordnumber'
...;
}
In many cases, boost::bind() is a nice alternative to WSignalMapper.

Wim.
