A note about confirmation buttons: Gwenhywfar has been designed with non-interactive applications in mind. For such an application it is important to know what button-press it has to simulate upon catching of a messagebox callback. This is what the confimation button flags are for. For informative messages the application may simply return the number of the confirmation button and be done. However, non-interactive applications should return an error (value 0) for messages classified as dangerous (see GWEN_GUI_MSG_FLAGS_SEVERITY_DANGEROUS) to avoid data loss. | |

Virtual User Interaction Functions | |
All text passed to the frontend via one of the following functions is expected to be an UTF-8 string which may contain newlines but no other control characters. Text delivered as argument called text throughout the documentation in this group may contain HTML tags. If it does a non-HTML version must be supplied, too. The text MUST begin with the non-HTML version, so that a frontend not capable of parsing HTML can simply exclude the HTML part by cutting before "<html". This is an example for HTML and non-HTML text: const char *text;
text="This is the non-HTML text"
"<html>"
"And this is the <b>HTML</b> version."
"</html>"
Frontends capable of parsing HTML (such as the KDE frontend) will extract the HTML information and show only that part of the string. Other frontends have to extract the non-HTML information and show only that. | |

Password Cache | |
This implementation provides a password cache. This will be consulted upon GWEN_Gui_GetPassword. The implementation of GWEN_Gui_SetPasswordStatus also accesses this password cache. Normally this cache is filled from password files (like those specified via option -P of aqbanking-cli). | |

This is the second level password storage. It can be used to safely store passwords in an encrypted file. This is used when a pin/password is requested which is not already in the password db (see Password Cache). This store is consulted if a given password is not found in the current pasword db (see GWEN_Gui_SetPasswordDb). | |

Dialogs | |
Providing dialog functionality is optional for the implementation. The internal implementations of the password and message box functions internally use dialog functions, so if your implementation of GWEN_GUI also implements the dialogs API then you're already set for most of the interactive callbacks. | |

#define GWEN_GUI_MSG_FLAGS_SEVERITY_MASK (0x7<<5) |
Check for the severity of the message. This allows non-interactive backends to react on the message accordingly. The backend calling this function thus allows the frontend to detect when the message is important regarding data security. E.g. a message like "Shall I delete this file" should be considered dangerous (since this might result in a data loss). However, the message "Application started" is not that dangerous ;-)
The following example allows to determine whether a message is dangerous:
#define GWEN_GUI_MSG_FLAGS_SEVERITY_NORMAL (0x0<<5) |
#define GWEN_GUI_MSG_FLAGS_TYPE_ERROR 2 |
#define GWEN_GUI_MSG_FLAGS_TYPE_INFO 0 |
#define GWEN_GUI_MSG_FLAGS_TYPE_IS_ERROR ((fl & GWEN_GUI_MSG_FLAGS_TYPE_MASK)==GWEN_GUI_MSG_FLAGS_TYPE_ERROR) |
#define GWEN_GUI_MSG_FLAGS_TYPE_IS_INFO | ( | fl | ) | ((fl & GWEN_GUI_MSG_FLAGS_TYPE_MASK)==GWEN_GUI_MSG_FLAGS_TYPE_INFO) |
#define GWEN_GUI_MSG_FLAGS_TYPE_IS_WARN | ( | fl | ) | ((fl & GWEN_GUI_MSG_FLAGS_TYPE_MASK)==GWEN_GUI_MSG_FLAGS_TYPE_WARN) |
#define GWEN_GUI_MSG_FLAGS_TYPE_MASK 0x07 |
Defines the mask to catch the message type. E.g. a check whether a message is a warning could be performed by:
#define GWEN_GUI_MSG_FLAGS_TYPE_WARN 1 |
#define GWEN_GUI_PROGRESS_NONE (0xffffffffUL) |
This value is used with GWEN_Gui_ProgressAdvance to flag that there really was no progress since the last call to that function but that that function should simply check for user interaction (without the need of updating the progress bar).
#define GWEN_GUI_PROGRESS_ONE (0xfffffffeUL) |
This value is used when the total number of steps is not known to the caller and he just wants to advance the progress by one (e.g. backends use this value when a job has been finished, but the backends do not know how many jobs there still are in AqBanking's queue).
#define GWEN_GUI_SHOWBOX_FLAGS_BEEP 0x00000001 |
Password/pin/tan entry method. The method id uses the higher 16 bits of a 32 bit word to define the method. The lower 16 bits are used to define the version of the method. E.g. the method for input using optical data (i.e. flicker code) knows multiple versions, currently 1.3 and 1.4. So the complete method id for optical input method HHD version 1.4 would be 0x20104. Use GWEN_Gui_PasswordMethod_Mask to get the basic method id.

Stack sync io layers above the given base layer.
This is a convenience function to extend a base layer (e.g. created by GWEN_SyncIo_Socket_new) to support HTTP or HTTPS over the given base layer.
You can use this function to allow for e.g. HTTPS over a socket created by functions GWEN_Socket_Accept and GWEN_SyncIo_Socket_TakeOver.

GWEN_GUI_PASSWORD_METHOD | methodId, | ||
GWEN_DB_NODE * | methodParams, | ||

) |
This function retrieves a password or pin. The implementation might want to use a cache or a password file. The default implementation simply asks the user for input. The function GWEN_Gui_SetPasswordStatus() is used to communicate the status of a password. So if this function here uses a password cache then the callback for GWEN_Gui_SetPasswordStatus() should also be implemented.
NOTE: AqBanking uses GWEN_Gui_PasswordMethod_OpticalHHD as methodId for all optical TAN input methods like "chipTAN optisch" and others. To determine which optical method is actually requested see the DB variable "tanMethodId" inside the methodParams parameter. The data to send to the TAN generator can be found in the toplevel variable "challenge".
flags | flags, see GWEN_GUI_INPUT_FLAGS_CONFIRM ff. |
token | unique identification for the password or pin. This can be used to read the password from a cache or file. |
title | title of the input box |
text | Text of the box: UTF-8, with both a normal text and a HTML variant of the text in the same string. See text restrictions note above. |
buffer | buffer to store the response in. Must have at least room for maxLen bytes |
minLen | minimal length of the password (if 0 then there is no low limit) |
maxLen | size of the buffer including the trailing NULL character. This means that if you want to ask the user for a PIN of at most 4 characters you need to supply a buffer of at least 5 bytes and provide a 5 as maxLen. |
methodId | Id of the pin/password/tan entry. |
methodParams | additional parameters for the pin/password/tan entry, content depends on the methodId (my be NULL for simple text input) |
guiid | id as returned by GWEN_Gui_ProgressStart or GWEN_Gui_ShowBox) |
GWENHYWFAR_API GWEN_DB_NODE* GWEN_Gui_GetPasswordDb | ( | const GWEN_GUI * | gui | ) |

This function is not officially part of the API but is needed for some ancient OpenHBCI keyfiles. License issues forbid us to link against OpenSSL so we leave it up to the application to implement this function. A converter tool might use this function once to convert an anciant OpenHBCI key file.

buffer | buffer to write the keydata generated from the given passphrase |
bufLengthr | size of that buffer |
GWENHYWFAR_API int GWEN_Gui_LogHook | ( | const char * | logDomain, |
GWEN_LOGGER_LEVEL | priority, | ||
const char * | s | ||
) |
This function is called internally by GWEN_Logger_Log. PLEASE NOTE: If you save the information in a file make sure to ignore messages from the log domain "gwenhywfar" with log level debug or higher, because those might contain sensitive information! Information of that level is not supposed to be saved to a file!
logDomain | logdomain of the given log message (e.g. "gwenhywfar") |
priority | priority of the message |
s | string to log |
GWENHYWFAR_API int GWEN_Gui_MessageBox | ( | uint32_t | flags, |
const char * | title, | ||
const char * | text, | ||
const char * | b1, | ||
const char * | b2, | ||
const char * | b3, | ||
uint32_t | guiid | ||
) |
Show a message box with optional buttons. The message box may either contain 1, 2 or three buttons. If only one button is wanted then b1 should hold a pointer to the button text (b2 and b3 must be NULL) In two-button mode b1 and b2 must be valid (b3 must be NULL) In three-button-mode b1, b2 and b3 must be valid pointers. The return value tells which button the user pressed:
If the frontend can not determine which button has been pressed (e.g. if no button was pressed but the user rather aborted the dialog by simply closing the box) it should return 0.
This function is blocking.
flags | flags, see GWEN_GUI_MSG_FLAGS_TYPE_MASK ff. |
title | title of the message box |
text | Text of the box: UTF-8, with both a normal text and a HTML variant of the text in the same string. See text restrictions note above. |
b1 | text for the first button (required), should be something like "Ok" (see text restrictions note above) |
b2 | text for the optional second button |
b3 | text for the optional third button |
guiid | id as returned by GWEN_Gui_ProgressStart or GWEN_Gui_ShowBox) |

GWENHYWFAR_API int GWEN_Gui_OpenDialog | ( | GWEN_DIALOG * | dlg, |
uint32_t | guiid | ||
) |
Open a dialog. This function should create all the necessary dialog resources (=windows) and return.
dlg | pointer to the dialog object |
guiid | id as returned by GWEN_Gui_ProgressStart, GWEN_Gui_ShowBox or as can be found via GWEN_Dialog_GetGuiId()) |
GWENHYWFAR_API int GWEN_Gui_Print | ( | const char * | docTitle, |
const char * | docType, | ||
const char * | descr, | ||
const char * | text, | ||
uint32_t | guiid | ||
) |
This function makes the application print something.
docTitle | title of the document. This might be presented to the user |
docType | an unique identifier of the document to be printed. This can be used by the application to separate printer settings for different document types. The name itself has no meaning and can be choosen freely by the caller. However, backends should append their name and a colon to keep this argument unique. This argument should not be translated. |
descr | an optional description about what the document contains. This might be shown to the user (see text restriction notes above). |
text | text to be printed (see text restriction notes above). |
guiid | id as returned by GWEN_Gui_ProgressStart or GWEN_Gui_ShowBox) |
GWENHYWFAR_API int GWEN_Gui_ProgressAdvance | ( | uint32_t | id, |
uint32_t | progress | ||
) |
Advances the progress bar an application might present to the user and checks whether the user wants to abort the operation currently in progress.
On graphical user interfaces this function should also check for user interaction and/or update the GUI (e.g. by calling qApp->processEvents() when using QT/KDE).
This function MUST return immediately (non-blocking).
id | id assigned by GWEN_Gui_ProgressStart (if 0 then the last started progress dialog is referred to) |
progress | new value for progress. A special value is GWEN_GUI_PROGRESS_NONE which means that the progress is unchanged. This might be used as a keepalive call to a GUI. |
GWENHYWFAR_API int GWEN_Gui_ProgressEnd | ( | uint32_t | id | ) |
Flags the end of the current operation. In graphical user interfaces this call should allow the user to close the progress dialog window.
On graphical user interfaces a call to this function should disable the abort button. It would be best not to close the dialog on receiption of this call but to simply enable a dialog closing (otherwise the user will not be able to see the log messages).
Whether this function is blocking or not depends on the status of the progress dialog and its initial flags. If the dialog needs to stay open for the user to read the log messages etc then this function only needs to return after the user manually closes the dialog.
If there is no reason to keep the dialog open then this function should simply close the dialog window and return immediately.
id | id assigned by GWEN_Gui_ProgressStart (if 0 then the last started progress dialog is referred to) |
GWENHYWFAR_API int GWEN_Gui_ProgressLog | ( | uint32_t | id, |
GWEN_LOGGER_LEVEL | level, | ||
const char * | text | ||
) |
Adds a log message to the referred process dialog.
This function MUST return immediately (non-blocking).
id | id assigned by GWEN_Gui_ProgressStart (if 0 then the last started progress dialog is referred to) |
level | log level (see GWEN_Gui_LogLevelPanic ff.) |
text | Text of the box: UTF-8, with both a normal text and a HTML variant of the text in the same string. See text restrictions note above. |
GWENHYWFAR_API int GWEN_Gui_ProgressLog2 | ( | uint32_t | id, |
GWEN_LOGGER_LEVEL | level, | ||
const char * | text, | ||
... | |||
) |
Adds a log message to the referred process dialog and returns immediately.
This is a convenience function to be used with variable number of arguments (like printf). It uses the given arguments to prepare a buffer which is then handed to GWEN_Gui_ProgressLog.
id | id assigned by GWEN_Gui_ProgressStart (if 0 then the last started progress dialog is referred to) |
level | log level (see GWEN_Gui_LogLevelPanic ff.) |
text | Text of the box (possibly including printf format string characters): UTF-8, with both a normal text and a HTML variant of the text in the same string. See text restrictions note above. |

const char * | title, | ||
const char * | text, | ||
uint64_t | total, | ||
uint32_t | guiid | ||
) |
This function is called when a long term operation is started. Theoretically nesting is allowed, however, you should refrain from opening multiple progress dialogs to avoid confusion of the user.
This function must return immediately (i.e. it MUST NOT wait for user interaction).
On graphical user interfaces such a dialog should contain a widget for the text presented here, a progress bar, a text widget to collect the log messages received via GWEN_Gui_ProgressLog and a button to allow the user to abort the current operation monitored by this dialog window.
Between a call to this function and one to GWEN_Gui_ProgressEnd the user should not be allowed to close the dialog window.
This function MUST return immediately (non-blocking).
title | title of the dialog |
text | Text of the box: UTF-8, with both a normal text and a HTML variant of the text in the same string. See text restrictions note above. |
total | total number of steps of the operation started (i.e. value which represents 100%) |
guiid | id as returned by GWEN_Gui_ProgressStart or GWEN_Gui_ShowBox) |
GWENHYWFAR_API int GWEN_Gui_RunDialog | ( | GWEN_DIALOG * | dlg, |
int | untilEnd | ||
) |
Run a dialog. This function should run the given dialog and return when the user is done with it.
dlg | pointer to the dialog object |
untilEnd | if not zero, the dialog should run until completely finished (e.g. "OK" pressed) |

int | persistent | ||
) |
Set the password DB. Takes over the given DB.
gui | GUI object |
dbPasswords | password cache |
persistent | if !=0 then the passwords come from a password file and a request to clear the password cache will be ignored. |
GWENHYWFAR_API int GWEN_Gui_SetPasswordStatus | ( | const char * | token, |
const char * | pin, | ||
GWEN_GUI_PASSWORD_STATUS | status, | ||
uint32_t | guiid | ||

GWENHYWFAR_API GWEN_DEPRECATED uint32_t GWEN_Gui_ShowBox | ( | uint32_t | flags, |
const char * | title, | ||
const char * | text, | ||
uint32_t | guiid | ||
) |
Shows a box with the given text. This function should return immediately, it should especially NOT wait for user input. This is used to show very important notices the user should see but which don't need user interaction. The message box will be removed later via GWEN_Gui_HideBox. It is ok to allow the user to prematurely close the box.
It is required for every call to this function to be followed later by a corresponding call to GWEN_Gui_HideBox.
This function MUST return immediately (non-blocking).
This function is deprecated (please use GWEN_Gui_ProgressLog() or others).
