Detailed Description
The QAssistantClient class provides a means of using Qt Assistant as an application's help tool.
Using Qt Assistant is simple: create a QAssistantClient instance, then call showPage() as often as necessary to show your help pages. When you call showPage(), Qt Assistant will be launched if it isn't already running.
The QAssistantClient instance can open (openAssistant()) or close (closeAssistant()) Qt Assistant whenever required. If Qt Assistant is open, isOpen() returns true.
One QAssistantClient instance interacts with one Qt Assistant instance, so every time you call openAssistant(), showPage() or closeAssistant() they are applied to the particular Qt Assistant instance associated with the QAssistantClient.
When you call openAssistant() the assistantOpened() signal is emitted. Similarly when closeAssistant() is called, assistantClosed() is emitted. In either case, if an error occurs, error() is emitted.
This class is not included in the Qt library itself. To use it you must link against libqassistantclient.a (Unix) or qassistantclient.lib (Windows), which is built into INSTALL/lib if you built the Qt tools (INSTALL is the directory where Qt is installed). If you use qmake, then you can simply add the following line to your pro file:
LIBS += -lqassistantclient

Property Documentation
open : const bool
This property holds whether Qt Assistant is open.
Access functions:
Member Function Documentation
QAssistantClient::QAssistantClient ( const QString & path, QObject * parent = 0 )
Constructs an assistant client with the given parent. The path specifies the path to the Qt Assistant executable. If path is an empty string the system path (%PATH% or $PATH) is used.
QAssistantClient::~QAssistantClient ()
Destroys the assistant client object.
void QAssistantClient::assistantClosed () [signal]
This signal is emitted when the connection to Qt Assistant is closed. This happens when the user exits Qt Assistant, if an error in the server or client occurs, or if closeAssistant() is called.
void QAssistantClient::assistantOpened () [signal]
This signal is emitted when Qt Assistant is open and the client-server communication is set up.
void QAssistantClient::closeAssistant () [virtual slot]
Use this function to close Qt Assistant.
See also assistantClosed().
void QAssistantClient::error ( const QString & message ) [signal]
This signal is emitted if Qt Assistant cannot be started, or if an error occurs during the initialization of the connection between Qt Assistant and the calling application. The message provides an explanation of the error.
void QAssistantClient::openAssistant () [virtual slot]
This function opens Qt Assistant, and sets up the client-server communiction between the application and Qt Assistant. If it is already open, this function does nothing. If an error occurs, error() is emitted.
See also assistantOpened().
void QAssistantClient::setArguments ( const QStringList & arguments )
Sets the command line arguments used when Qt Assistant is started.
void QAssistantClient::showPage ( const QString & page ) [virtual slot]
Call this function to make Qt Assistant show a particular page. The page is a filename (e.g. myhelpfile.html). See Qt Assistant Manual#Modifying the Default Documentation Set for further information.
If Qt Assistant hasn't been opened yet, this function will do nothing. You can use isOpen() to determine whether Qt Assistant is up and running, or you can connect to the asssistantOpened() signal.
See also isOpen() and assistantOpened().
