Where is SimEvent::process() ?

#1 OK. A second look tells me that there is no generic SimEvent, nor is there an event appropriate for this (if I'm wrong, please let me know).

That being the case, I'll just make my own...

#2 SimEvent is the base class for all specific event classes you create - basically it encapsulates the behavior "call me at some later time with a certain object as a parameter". So the idea is you subclass SimEvent and override process to do your special processing - for an example of this, check engine/game/net/serverQuery.cc - it has a bunch of SimEvent derivatives to handle pings, queries, heartbeat packets, etc.

#3 Yeah I kinda figured that out (and from the object you mention as well). I wish I could delete the entire thread - I feel lame now. :)

Thank you anyway.

#4 Yeesh. I'm starting to feel like a leech here, but can anyone offer further insight? I'm stuck.

Here's what I have...

Created an event object:

class GuiActiveScreenEvent : public SimEvent
{
	S32 tx;
	S32 ty;
	S32 tw;
	S32 th;

	public:
		GuiActiveScreenEvent(S32 x, S32 y, S32 w, S32 h)
		{
			tx = x;
			ty = y;
			tw = w;
			th = h;
		}
		void process(SimObject* obj)
		{
			((GuiActiveScreen*)obj)->handleEvent(tx, ty, tw, th);
		}
};

and I implemented GuiActiveScreen::handleEvent(). This compiles fine. Next, I need my object to be able to clear any existing events associated with it and insert a new event. I envisioned doing something like

Sim::cancelPendingEvents(this);
GuiActiveScreenEvent evt = GuiActiveScreenEvent(0,0,100,100);
Sim::postEvent(this, evt, 20);

but that fails miserably. The call to cancelPendingEvents() results in:

<blahblah>\guiActiveScreen.cc(127) : error C2039: 'cancelPendingEvents' : is not a member of 'Sim'
<blahblah>\guiActiveScreen.cc(127) : error C2065: 'cancelPendingEvents' : undeclared identifier

I looked at the implementation of cancelPendingEvents() in console\simManager.cc and I see

namespace Sim
{

...

static void cancelPendingEvents(SimObject *obj)
{
...

and the only other place I see a call to that function uses the same syntax I used. I assume this is some bit of C++ wisdom I'm not privy to -- prolly related to the namespace. I'm stumped tho.

Then the line 'Sim::postEvent(this, evt, 20);' produces the error

<blahblah>\guiActiveScreen.cc(130) : error C2665: 'postEvent' : none of the 3 overloads
can convert parameter 2 from type 'class GuiActiveScreenEvent'

I've no idea there. I will continue looking, but like I said, I think I may be missing something fundamental. I simply want to be able to queue up events for a GuiControl-derived class without going the ugly path of using console events - the point of writing this class was to avoid that overhead in the first place.

I know that GG staff is busy. For that matter everyone is, really. But if anyone can offer insight into what I'm doing wrong, or mebbe just a general sketch of how to get what I'm looking for, I would sincerely appreciate it.

#5 It has to do with the fact that the function is static. The one place where the function is called is within the file on:

SimObject::unregisterObject()
{
...
Sim::cancelPendingEvents(this);
}

Just for reference a static function can only be called within the file itself, so only in the simManager can you call cancelPendingEvents(). So you could just create a function in simManager that is not static to call cancelPendingEvents()

#6 I knew I was spending too much time on Java... (thank my employers, who had me doing Java _only_ for way too many years). Thanks. Now to figure out the other error.
