connection from button to slot with parameter of type QSqlDatabase*

[herbstritter]

Hi,

i want to connect a QPushButton to a slot create(QSqlDatabase *database), but i get the following:

QObject::connect: Incompatible sender/receiver arguments
QPushButton::clicked() --> CreateCupDialog::create(QSqlDatabase*)

QObject::connect: Incompatible sender/receiver arguments
QPushButton::clicked() --> CreateCupDialog::create(QSqlDatabase*)

To copy to clipboard, switch view to plain text mode 

Do i have to change my slot to create() because the button cant send a QSqlDatabase* type? how do i get my pointer passed to the functions executed in create()?

thanks for your help.
