[gme-users] FW: GME and python

[Zoltan Molnar]

Hi,

Below is a sample script of using GME through Idispatch interface in
Python.
The other main creatable COM object is GME.Application. 
You can find the description of these interfaces in the GME/interfaces/
directory, especially in Mga.idl and Gme.idl.


import win32com.client
def createMyProject():
        """ Creates my SignalFlow project, with a Compound containing 5
Primitives"""
        project = win32com.client.Dispatch("Mga.MgaProject")
        mganame = "f:\\proj\\pdok\\pythonDemo\\gen1.mga"
        project.Create( "MGA=" + mganame, "SF")

        project.BeginTransaction( project.CreateTerritory( None, None,
None), 0)
        
        metaroot = project.RootMeta.RootFolder
        mfol = metaroot.LegalChildFolderByName( 'Folder')
        
        mkind = metaroot.DefinedFCOByName( 'Compound', 1)
        pkind = metaroot.DefinedFCOByName( 'Primitive', 1)
        metaroleOutSig = mkind.RoleByName( 'OutputSignals')
        metaroleInpSig = mkind.RoleByName( 'InputSignals')
        metaroleInpSig = pkind.RoleByName( 'InputSignals')
        metarolePrimit = mkind.RoleByName( 'PrimitiveParts')
        metaroleDFC    = mkind.RoleByName( 'DFC')
        
        # create a compound
        main = project.RootFolder.CreateRootObject( mkind)
        main.Name = 'Main'
        
        dst = main.CreateChildObject( metarolePrimit)
        dst.Name = 'DST'

        srcs = []
        for i in range(4):
                primit = main.CreateChildObject( metarolePrimit)
                primit.Name = 'SRC' + str(i)
                srcs.append( primit)
                
        insports = []
        for i in range(4):
                ins = dst.CreateChildObject( metaroleInpSig)
                ins.Name = 'InputSignal' + str(i)
                insports.append( ins)
        
        outsports = []
        for i in range(4):
                outs = srcs[i].CreateChildObject( metaroleInpSig)
                outs.Name = 'OutputSignal'
                outsports.append( outs)

        dummyColl = win32com.client.Dispatch("Mga.MgaFCOs")
        for i in range(4):
                main.CreateSimpleConn( metaroleDFC, outsports[i],
insports[i], dummyColl, dummyColl)

        
        project.CommitTransaction()

        project.Save()
        project.Close(0)
