Of course, you might want to rely on the de facto standard for supplying help to users: the F1 key. The reference documentation is made available through the Qt Assistant that is bundled with Qt. When you need to provide help, you can also use Assistant as the help system for your application. Doing so is a two-stage process: configure Assistant and then integrate Assistant in your application.

Qt Assistant can render HTML documentation, so you have to format your help files using HTML format to take advantage of this feature. The HTML files and images are placed in a directory next to the executable file alongside two more files needed by Assistant. The first and most important file is the Assistant Documentation Profile called qtbookexample.adp. This file configures Assistant so the right documentation set is used and the window title is set up correctly. You can see the contents of the file in Listing 9-16. The second file needed by Assistant is the about.txt file used to customize the about box in Assistant. You can see that it is referenced from the profile part of the adp file. The profile part configures the appearance of Assistant, configuring it with a window title, an icon, a start page, a text for the about menu, the file that contains the text for the about box, and the relative path to the rest of the documents. Listing 9-16. The Assistant documentation profile file <!DOCTYPE DCF> <assistantconfig version="3.2.0"> <profile> <property name="name">qtbookexample</property> <property name="title">Qt Book Example</property> <property name="applicationicon">images/qt.png</property>

Figure 9-16 shows how the information is shown in the Contents and Index tabs of Assistant. The other tabs take care of themselves. The bookmarks are added by the user, and the Search tab offers searching throughout all files referenced from the adp file. To test your adp file with Assistant, you can start Assistant with the parameter profile and then refer to your profile. For example, assistant profile qtbookexample.adp starts Assistant with the qtbookexample.adp documentation, as shown in Figure 9-16.

Putting It Together
To use Assistant as your help documentation browser, you need to create a QAssistantClient object. Make sure that you create only one object for your entire application the user might be confused if you start several Assistant instances at once. Listing 9-17 shows how to create an assistant client object. The first argument given to the constructor is a path to the Assistant executable. If you assume that the users have a working Qt development environment installed, you can use the QLibraryInfo object to find the executables. In the most common situation, the user doesn t have Qt installed so you have to ship the Assistant executable with your application and place it relative to your application s executable. You can find the location of your file by using the QApplication::applicationDirPath() method. Listing 9-17. Creating and configuring Assistant QAssistantClient *assistantClient = new QAssistantClient( QApplication::applicationDirPath(), qApp ); QStringList arguments; arguments << "-profile" << "./documentation/qtbookexample.adp"; assistantClient->setArguments( arguments ); When you want to show the Assistant, simply call one of the openAssistant() or showPage(const QString&) methods of your assistant client object. When your application closes, make sure to call closeAssistant() on your client object to close down any open instance of Assistant. To be able to build a project using the QAssistantClient class, you must add the line CONFIG += assistant to your project file.
