Methods of class <code>Model</code> are listed below :
|

|
|
|
||
|
|
<UL>
|
||
|
|
<LI><code>HurricanePlug</code> : Creates the Hurricane cell thanks to the stratus cell.
|
||
|
|
<BR>
|
||
|
|
Before calling this method, only the stratus cell is created, after this method, both cells are created. This method has to be called before View and Save, and before Layout.
|
||
|
|
</LI>
|
||
|
|
<LI><code>View</code> : Opens/Refreshes the editor in order to see the created layout
|
||
|
|
</LI>
|
||
|
|
<LI><code>Quit</code> : Finishes a cell without saving
|
||
|
|
</LI>
|
||
|
|
<LI><code>Save</code> : Saves the created cell
|
||
|
|
<BR>
|
||
|
|
If several cells have been created, they are all going to be saved in separated files
|
||
|
|
<BR></LI>
|
||
|
|
</UL>
|
||
|
|
|
