\title Qutlook Example (ActiveQt)
The Qutlook example demonstrates the use of ActiveQt to automate
Outlook. The example makes use of the \l dumpcpp tool to generate
a C++ namespace for the type library describing the Outlook
Object Model.
The project file for the example looks like this:
\snippet examples/activeqt/qutlook/qutlook.pro 1
\snippet examples/activeqt/qutlook/qutlook.pro 2
The project file uses the \c dumpcpp tool to add an MS Outlook type library to the project.
If this fails, then the generated makefile will just print an error message, otherwise
the build step will now run the \e dumpcpp tool on the type library, and
generate a header and a cpp file (in this case, \c msoutl.h and \c msoutl.cpp) that
declares and implement an easy to use API to the Outlook objects.
\snippet examples/activeqt/qutlook/addressview.h 0
The AddressView class is a QWidget subclass for the user interface. The QTreeView widget
will display the contents of Outlook's Contact folder as provided by the \c{model}.
\snippet examples/activeqt/qutlook/addressview.cpp 0
The AddressBookModel class is a QAbstractListModel subclass that communicates directly with
Outlook, using a QHash for caching.
\snippet examples/activeqt/qutlook/addressview.cpp 1
The constructor initializes Outlook. The various signals Outlook provides to notify about
contents changes are connected to the \c updateOutlook() slot.
\snippet examples/activeqt/qutlook/addressview.cpp 2
The destructor logs off from the session.
\snippet examples/activeqt/qutlook/addressview.cpp 3
The \c rowCount() implementation returns the number of entries as reported by Outlook. \c columnCount
and \c headerData are implemented to show four columns in the tree view.
\snippet examples/activeqt/qutlook/addressview.cpp 4
The \c headerData() implementation returns hardcoded strings.
\snippet examples/activeqt/qutlook/addressview.cpp 5
The \c data() implementation is the core of the model. If the requested data is in the cache the
cached value is used, otherwise the data is acquired from Outlook.
\snippet examples/activeqt/qutlook/addressview.cpp 6
The \c changeItem() slot is called when the user changes the current entry using the user interface.
The Outlook item is accessed using the Outlook API, and is modified using the property setters.
Finally, the item is saved to Outlook, and removed from the cache. Note that the model does not
signal the view of the data change, as Outlook will emit a signal on its own.
\snippet examples/activeqt/qutlook/addressview.cpp 7
The \c addItem() slot calls the CreateItem method of Outlook to create a new contact item,
sets the properties of the new item to the values entered by the user and saves the item.
\snippet examples/activeqt/qutlook/addressview.cpp 8
The \c update() slot clears the cache, and emits the reset() signal to notify the view about the
data change requiring a redraw of the contents.
\snippet examples/activeqt/qutlook/addressview.cpp 9
\snippet examples/activeqt/qutlook/addressview.cpp 10
The rest of the file implements the user interface using only Qt APIs, i.e. without communicating
with Outlook directly.
\snippet examples/activeqt/qutlook/main.cpp 0
The \c main() entry point function finally instantiates the user interface and enters the
event loop.
To build the example you must first build the QAxContainer
library. Then run your make tool in \c examples/activeqt/qutlook
and run the resulting \c qutlook.exe.
