[Gvsig_english] Scripting to draw a line in the gvSIG

[gracecwl]

Hi Pablo Piqueras Bartolomé,

Thx for your provided idea.Actually, we plan to add a function whereby the
gvSIG can provide 'theme' to the user. Then 'theme' idea, we hope to add in
the scripting python. So whenever user run the script, it will open a dialog
box for user to check/uncheck which layers they wish to view. And the info
for the layer is actually taken from the mySQL. 

We very appreaciate your help in guide us the way to write the script.
Franky, we still no familiar with the library in the gvSIG.




thanks and regrads,
grace
