Hi,
I fixed every obvious problem I had with the ParaGUI library using Borland
C++ Builder 5.
I solved the event problem by using a template function called
"SetEventObject" in PG_MessageObject with the following definition:
template <class T>
void SetEventObject(PG_MSG_TYPE type, T* calledobj, MSG_CALLBACK_OBJ cbfunc,
void *clientdata = NULL) {
RegisterEventHandlerObj(type, this, (void*) calledobj, calledobj,
cbfunc, clientdata);
}
where RegisterEventHandlerObj is just a wrapper for
PG_RegisterEventHandlerObj to avoid namespace pollution by including
pgmsgmap.h at the beginning of pgmessageobject.h
I also enhanced the structure PG_EVENTHANDLERDATA by the member
void *calledobj_real;
The function "PG_MessageObject::SendMessage" contains the instruction to call
the event handler. The specific lines have to be changed to:
if(cbdata->calledobj != NULL) {
rc = (((PG_EventObject*) cbdata->calledobj_real)->*(cbdata->obj_cbfunc))(id,
(PG_Widget*)this, data, cbdata->data);
}
Now my questions are:
1. How can I apply patches?
2. How will the testing be done for the other platforms?
