Every argument of the user interface is defined by querying the user
interface elements. The backslash at the end of a line allows the command
flag argument to span multiple lines.
Your user interface is now fully functional!
A completed version of the user interface script named Mel_UI_Final.mel is
available in the GettingStarted project directory (GettingStarted/mel).
Saving the script
To use your script in other scenes, you must save it. To execute the MEL
commands in a script file without having to open it every time you want to
use it, you must use global procedures.
Once you’ve saved a MEL script file that contains a global procedure in the
default script folder of Maya, you can access it whenever you type MEL
commands. Other procedures in the script file can only be called by the global
procedure(s) defined in the script file or other local procedures.
Maya automatically sources procedures in its default scripts folders at start
up. A script in the default Maya script folder has the same name as a global
procedure defined in the script file, when you type the name of the script file,
the global procedure within the script file will be executed. This allows you
to create scripts that operate similar to built-in Maya commands.
1 Type the following at the top of MEL2:
global proc makeRoll_create_UI() {
2 At the bottom of MEL2, type the following:
}
Your entire user interface script should be between the curly braces.
3 Highlight the entire script by selecting Edit > Select All from the Script
Editor menu bar.
4 With the script highlighted, save the script by selecting File > Save Script
from the Script Editor.
The Script Editor only saves the highlighted commands when saving a
script.
5 Save the script as makeRoll_create_UI.mel in the GettingStarted/mel
folder.
