hi folks,

imagine i want to do the following


void MyCallback::Action(int i, float f)
{
	RLOG("" << i << " " << f);
}

void MyCallback::Test()
{
	Callback1<int> cb;
	cb = callback2(this, &CLASSNAME::Action, 1.0f); //latter param already specified
	cb(123); //first parameter specified now
}

partially specify the arguments to the callback, the rest specify later.

would it be possible with callbacks (i imagine one needs to extend the template generators for that)?

Hi kohait,

If I understand right what you want to achieve, than it is possible and actually quite easy Wink

void MyCallback::Action(int i, float f)
{
	RLOG("" << i << " " << f);
}

void MyCallback::Test()
{
	Callback1<int> cb;
	cb = callback1(this, &CLASSNAME::Action, 1.0f);
	cb(123);
}

As you can see, you were very close, just one letter is different Smile

Hope I got you question right, it looks suspiciously simple.

Best regards,
Honza
