Overall Presentation

The graphical interface is available by using its autonomous executable jar (no need other dynamic libraries). The main frame is then composed of four parts:

1. The menu bar where the user may find the main commands via four menus: File, Windows, Option and About.

2. A banner where are stored some widgets corresponding to the main commands:

- “Load context” button that will display a file explorer to select some previous GENTLEMAN context file (at XML format).

- “Save context” button that will display a file explorer to select a name for the actual GENTLEMAN context.

- “Save results” button: a new window will appear where it will be possible to define the suffix with which the results files as well as the corresponding context file will be saved.

Via this new window, it will also possible to (re)define the directories where to put these saved context and saved results files. For example, with these entries:

We will save:

. GTM_test.xml for the context file,

. GTM_test.log for the log file (that will include TLE(s) as shown in the console),

. GTM_DIF_test.txt for the file that will include difference betwwen "real" ephemeris and the one issued from TLE(s) generation.

- “Compute” button: to start … but also to stop the computation

- “Clear results” button that will clear the output written in the specific Console tab (see Console)

- “Clear messages” button that will clear the sub window dedicated to messages

- A progression bar that will indicate approximatively the progression of the propagation.

- “Quit” button: to exit the application (also possible by clicking on the cross of the main frame)

3. A sub window dedicated to messages as error messages.

4. At last the main part of the frame dedicated to either input or output data. As there are many data, this frame has been split in different tabs that will be described below.
