New component based on PYHELLO example

Hello,

I try to write a new salome component written in python . I started with PYHELLO example and rename "Hello" with "MyComponent".

The salome gui is launching properly but i have this error when i try to call a method defined in the idl file.

Traceback (most recent call last):
  File "/home/godin/salome_5.1.5/MYCOMPONENT_5.1.5/bin/salome/MYCOMPONENTGUI.py", line 224, in OnGUIEvent
    dict_command[commandID]()
  File "/home/godin/salome_5.1.5/MYCOMPONENT_5.1.5/bin/salome/MYCOMPONENTGUI.py", line 262, in CallMeth
    getEngine().meth( _getStudy() )
  File "/home/godin/salome_5.1.5/MYCOMPONENT_5.1.5/lib/python2.4/site-packages/salome/MYCOMPONENT_Gen_idl.py", line 68, in meth
    return _omnipy.invoke(self, "meth", _0_MYCOMPONENT_ORB.MYCOMPONENT_Gen._d_meth, args)
UNKNOWN: CORBA.UNKNOWN(omniORB.UNKNOWN_PythonException, CORBA.COMPLETED_MAYBE)
th. 140573188360064 end of trace

Here is the definition in the idl file

module MYCOMPONENT_ORB
{
  interface MYCOMPONENT_Gen : Engines::Component, SALOMEDS:river
  {
      void meth(in SALOMEDS::Study theStudy)
          raises (SALOME::SALOME_Exception);
  };
};

The definition of the method.

class MYCOMPONENT(MYCOMPONENT_ORB__POA.MYCOMPONENT_Gen,
              SALOME_ComponentPy.SALOME_ComponentPy_i,
              SALOME_DriverPy.SALOME_DriverPy_i):

    def meth( self, study ):

        print(meth)
        pass

Thanks for your help.

Hello all,

I have solve the preceding problems.

Now i have some difficulties to manage Objects through python/corba and GUI.

Again on the PYHELLO sample component, these functions have a strange behavior.

:

module PYHELLO_ORB
{
  interface PYHELLO_Gen : Engines::Component, SALOMEDS:river
  {
    GEOM::GEOM_Object test()
      raises (SALOME::SALOME_Exception);

    void test2(in GEOM::GEOM_Object obj)
      raises (SALOME::SALOME_Exception);
  };
};

An the implementation in PYHELLO.py

def test(self):
       return geompy.MakeVertex(0., 0., 0.)

def test2(self, object):
   geompy.addToStudy(object, "Object")

As you can see the first function (test) create a new vertex and the second (test2) add a object to study.

I built this code and launch salome to execute the following script

 from batchmode_salome import lcc
import PYHELLO_ORB
import geompy
pyhello = lcc.FindOrLoadComponent( 'FactoryServerPy', 'PYHELLO' )

vertex = pyhello.test()
pyhello.test2(vertex) # <----- doesn't work
geompy.addtoStudy(vertex, "Vertex") # <----- works !

The call to pyhello.test2(vertex) doesn't work, the object is not present in the study, but when i call directly geompy.addToStudy(..), it works perfectly ?

What's wrong with this ? I think i haven't understood all salome concepts !

Hello,

I am new to salome and I want to develop new module to integrate in Salome.

I will need (I guess) to do it with C++ but I think I will try first with python to understand all the concept.

Did you suceed ?

Thanks for your feed back ! I know it's a long time but I try.

Hi Damien,

I am happy to see that someone has the same idea as me : developing a new component in Salome.

.

Sincerely.

Hi Pascal

To make PYHELLO appear in SALOME, one of the ways is to explicitly specify PYHELLO as a module to run (be default it is not run) this way:
$ runSalome -mPYHELLO

After that, when you create a new study, PYHELLO module will be activated.
