roslaunch rqt

edit

Hello,

Is it possible to perform a .launch with rqt?

I can use my puglin with rqt and I use two terminals, one for call rqt and the other to call a .launch. I want to include rqt in my .launch, is it possible?

<launch>

    <node pkg="rosbag" type="play" name="player" output="screen" args="--clock /home/user/bags/bag.bag"/>
    <node pkg="a_package" type="a_node" name="a_node"/>

</launch>

I tried this one but it is wrong:

<launch>

    <node pkg="rqt" type="rqt" name="rqt"/>

</launch>
