Member Function Documentation

hk_connection * hk_drivermanager::find_existing_connection (  const hk_string &  drivername, const hk_string &  host, unsigned int  tcp_port, const hk_string &  user )

If an already created connection exists, it will be returned otherwise NULL

hk_connection * hk_drivermanager::new_connection (  const hk_string &  drivername = "", enum_interaction  i = interactive )

with this method you can create a new connection to a database. If no driver is set a dialog appears which asks for the driver. You can set a GUI dependend driverdialog with set_driverselectdialog. Parameters: drivername  name of the wished database driver (i.e. mysql) i  if i is set to 'interactive' warningmessages and dialog boxes will be shown Returns: a driver specific version of hk_connection or NULL if no driver could be found.

void hk_drivermanager::set_driverselectdialog (  requestdialogtype *  dialog  )  [static]

you can write your own GUI dependend function to show a driver select dialog by defining a function of requestdialogtype

void hk_drivermanager::set_path (  const hk_string &  path  )  [static]

Path to the directory where the database drivers are stored.(default: /usr/lib/hk_classes/drivers)
