RTI Launcher
************
The following issues affect backward compatibility in *Launcher* 
starting in Release 6.0.0. 


Configuration
=============

Custom buttons
----------------------
If you added custom buttons to the User tab in previous releases,
you need to make the following changes to continue seeing the User
tab and buttons:

   #. Open your old ``user.xml`` file: |br|
      ``rti_workspace/<version>/user_config/launcher/panels/user.xml``.
      |br|
      |br|
   #. In your 6.0.0 installation, look for the following: |br|
      ``rti_workspace/<version>/user_config/launcher/panels/user/example.xml``.
      |br|
      |br|
   #. Make a copy of ``example.xml`` for each button that you have and
      rename the file how you want. (The buttons will display alphabetically
      by .xml file name.)
      |br|
      |br|
   #. Copy each ``<button name="your_button_name">`` tag component from your
      old ``user.xml`` file to each renamed ``example.xml`` file.
      |br|
      |br|
   #. To set the order of the buttons in the User tab, do one of the following:

      * Modify ``configuration.xml``.
      * Modify your ``example.xml`` file names to set the order of the
        buttons alphabetically. |br|
        |br|


      *Launcher* orders the buttons in the User tab as specified in
      ``configuration.xml`` or, if not specified there, alphabetically by
      ``example.xml`` file name.

See :link_launcher_button_usersman_600:`"Adding a Button to the Launcher’s User
Panel," in the RTI Launcher User’s Manual <>` for more details.


New GTK+ dependency
--------------------
To run *Launcher* on a Linux system, *Launcher* requires at least GTK+ 2 version
2.24.0 and its dependencies. As a result, *Launcher* might not be able to
run on some operating systems, such as SuSE 11 SP2 (which has an older
version of GTK+ 2).
