\section1 Configuring Connections in Qt Creator
To be able to run and debug applications on the Maemo emulator and
devices, you must set up a connection to the emulator and the device in the
Qt Creator build and run settings. If you install Nokia Qt SDK, the
necessary software is installed and configured automatically and you
only need to configure a connection to the device.
You can protect the connections between Qt Creator and the Maemo emulator
or a device by using either a password or an SSH key. You must always
use a password for the initial connection, but can then deploy an SSH
key and use it for subsequent connections. If you use a password, you
must generate it in Mad Developer and enter it in Qt Creator every time
you connect to the Maemo emulator or to a device.
If you do not have an SSH key, you can create it in Qt Creator. For more
information, see \l{Generating SSH Keys}.
To configure connections between Qt Creator and the Maemo emulator or
device:
\list 1
\o If you install the Maemo emulator (QEMU) separately, you must
specify parameters to access it:
\list a
\o Start Mad Developer in the emulator.
\o Click \gui {Developer Password} to generate a password for
the connection.
\o In Qt Creator, select \gui {Tools > Options... > Projects >
Maemo Device Configurations > Add} to add a new configuration.

\o In the \gui {Configuration name} field, enter a name for
the connection.
\o In the \gui {Device type} field, select \gui {Local simulator}.
\o In the \gui {Authentication type} field, select \gui Password
for the initial connection.
\o In the \gui Password field, enter the password from the Mad
Developer for the initial connection.
You can use the default values for the other fields.
\o Click \gui Test to test the connection.
\o To avoid having to specify the password every time you connect
to the Maemo emulator, click \gui {Deploy Key...} and select
the file that contains your public key.
\o When you have deployed the key to the device, change the
configuration to use the SSH key for protection.

\gui {Private key file} field.

If you installed the Nokia Qt SDK, you can omit this step.

\title Using the Maemo Emulator
The Maemo emulator emulates the Nokia N900 device environment. You can test
applications in conditions practically identical to running the application
on a Nokia N900 device. You can test user interaction by using the keypad and
touch emulation.
\note The Maemo emulator support requires the Nokia N900 PR1.2 update.
To test the application UI, user interaction with the application, and
functionality that uses the mobility APIs, use the Qt Simulator,
instead. For more information, see the
\l{http://doc.qt.nokia.com/qt-simulator-beta/index.html}{Qt Simulator Manual}.
The Maemo emulator is installed and configured as part of the Nokia Qt SDK
package. You can also install and configure the MADDE environment and
Maemo emulator separately. For more information, see
\l{Setting Up Development Environment for Maemo}.
\section1 Starting the Maemo Emulator
The \gui {Start Maemo Emulator} button is visible if you have a project
open in Qt Creator for which you have added the Maemo build target.
To start the Maemo emulator:

\o Select \gui {Mad Developer} on the Maemo emulator, to start the Mad Developer

\o If you have not deployed an SSH key to protect the connection between
Qt Creator and the Maemo emulator, select \gui {Developer Password} to generate
a password.
\o In Qt Creator, enter the password in the connection settings:
\gui {Tools > Options... > Projects > Maemo Device Configurations}.
