## Static Method Documentation

QString FormDataFolder | ( |  | ) |

The standardized name of the form data folder. It is automatically created when a wallet is created, but the user may still delete it so you should check for its existence and recreate it if necessary and desired.

QString LocalWallet | ( |  | ) |

The name of the wallet used to store local passwords.

QString NetworkWallet | ( |  | ) |

The name of the wallet used to store network passwords.

QString PasswordFolder | ( |  | ) |

The standardized name of the password folder. It is automatically created when a wallet is created, but the user may still delete it so you should check for its existence and recreate it if necessary and desired.

changePassword | ( | QString | name,
|  | int | w
| ) |  |  |

Request to the wallet service to change the password of the wallet name.

Parameters:

  | name | The the wallet to change the password of.
  | w | The window id to associate any dialogs with. You can pass 0 if you don't have a window the password dialog should associate with.

int closeWallet | ( | QString | name,
|  | bool | force
| ) |  |  |

Close the wallet name. The wallet will only be closed if it is open but not in use (rare), or if it is forced closed.

Parameters:

  | name | The name of the wallet to close.
  | force | Set true to force the wallet closed even if it is in use by others.

Returns:
  Returns 0 on success, non-zero on error.

int deleteWallet | ( | QString | name
| ) |  |  |

Delete the wallet name. The wallet will be forced closed first.

Parameters:

  | name | The name of the wallet to delete.

Returns:
  Returns 0 on success, non-zero on error.

bool disconnectApplication | ( | QString | wallet,
|  | QString | app
| ) |  |  |

Disconnect the application app from wallet.

Parameters:

  | wallet | The name of the wallet to disconnect.
  | app | The name of the application to disconnect.

Returns:
  Returns true on success, false on error.

bool folderDoesNotExist | ( | QString | wallet,
|  | QString | folder
| ) |  |  |

Determine if a folder does not exist in a wallet. This does not require decryption of the wallet. This is a handy optimization to avoid prompting the user if your data is certainly not in the wallet.

Parameters:

  | wallet | The wallet to look in.
  | folder | The folder to look up.

Returns:
  Returns true if the folder does NOT exist in the wallet, or the wallet does not exist.

bool isEnabled | ( |  | ) |

Determine if the KDE wallet is enabled. Normally you do not need to use this because openWallet() will just fail.

Returns:
  Returns true if the wallet enabled, else false.

bool isOpen | ( | QString | name
| ) |  |  |

Determine if the current wallet is open, and is a valid wallet handle.

Returns:
  Returns true if the wallet handle is valid and open.

bool keyDoesNotExist | ( | QString | wallet,
|  | QString | folder,
|  | QString | key
| ) |  |  |

Determine if an entry in a folder does not exist in a wallet. This does not require decryption of the wallet. This is a handy optimization to avoid prompting the user if your data is certainly not in the wallet.

Parameters:

  | wallet | The wallet to look in.
  | folder | The folder to look in.
  | key | The key to look up.

Returns:
  Returns true if the key does NOT exist in the wallet, or the folder or wallet does not exist.

KWallet.Wallet openWallet | ( | QString | name,
|  | int | w,
|  | KWallet.Wallet.OpenType | ot=KWallet.Wallet.Synchronous
| ) |  |  |

Open the wallet name. The user will be prompted to allow your application to open the wallet, and may be prompted for a password. You are responsible for deleting this object when you are done with it.

Parameters:

  | name | The name of the wallet to open.
  | ot | If Asynchronous, the call will return immediately with a non-null pointer to an invalid wallet. You must immediately connect the walletOpened() signal to a slot so that you will know when it is opened, or when it fails.
  | w | The window id to associate any dialogs with. You can pass 0 if you don't have a window the password dialog should associate with.

Returns:
  Returns a pointer to the wallet if successful, or a null pointer on error or if rejected.

QStringList users | ( | QString | wallet
| ) |  |  |

List the applications that are using the wallet wallet.

Parameters:

  | wallet | The wallet to query.

Returns:
  Returns a list of all DCOP application IDs using the wallet.

QStringList walletList | ( |  | ) |

List all the wallets available.

Returns:
  Returns a list of the names of all wallets that are open.
