Hi Paco,
First of all thanks for your help.
I do not know if you see the class java that I send, but I have a problem.
I have two class DisegnaPoligonoExtension and DisegnaPoligonoPlugIn
DisegnaPoligonoPlugIn extends DrawPolygonTool and implements PlugIn, in the
method install of the class DisegnaPoligonoExtension I must initialize
DisegnaPoligonoPlugIn
private DisegnaPoligonoPlugIn disegnapoligonoPlugIn;
public void install( PlugInContext context ) throws Exception {
if(disegnapoligonoPlugIn == null)
{
disegnapoligonoPlugIn = new DisegnaPoligonoPlugIn(null);
.....
}
I initialize to null is correct? If no which value I can use
When I execute the extension I have the following problem
14/02/2007 12:29:55 ERROR root:197 - Exception in thread "main"

Hi, Giovanni,
#execute is the first method called in the plugin. It is used to test
initial state (checking that there is an editable layer, for example).
If execute returns true (indicating the test was satisfied) the plugin
continues executing. Then, the user can draw the poligon and after
finishing drawing the method #gestureFinished is called. Here, into
#gestureFinished (you must override it), you can introduce the
functionality you want (for example, to show a message indicating the
number of vertices of the new polygon).
I can't send you an example now, I'm sorry. Maybe another list user can.
Regards.
