Hi,
I have a question regarding the npsimple plug-in sample
located at /modules/plugin/test . This plug-in is
scriptable, so it's implemented as an XPCOM component
that goes into component subfolder.
I observed that
a) the binary has 312DA841-3DBF-11d3-BCFB-00A0C9C8D91D
as CID, defined in simpleCID.h:
#define NS_SIMPLEPLUGIN_CID \
{ 0x312da841, 0x3dbf, 0x11d3, \
{ 0xbc, 0xfb, 0x0, 0xa0, 0xc9, 0xc8, 0xd9, 0x1d } }
b) the IDL file nsISimplePluginInstance.idl (and the derived header
_xpidl\nsISimplePluginInstance.h) has
fa8728f0-117a-11d4-8fa5-0010a4e73d9a as IID:
#define NS_ISIMPLEPLUGININSTANCE_IID \
{ 0xfa8728f0, 0x117a, 0x11d4, \
{ 0x8f, 0xa5, 0x00, 0x10, 0xa4, 0xe7, 0x3d, 0x9a }}
Why is there a difference between component ID and interface ID?
Please try to explain it in simple words for an XPCOM beginner.
Can the interface be viewed as some kind of separate component
itself?
TIA - Regards, Tobias Trelle
