[sword-devel] How to handle text context

[Manfred Bergmann]

Yeah, thanks, Troy.

I figured something similar but I'm operating on a VerseKey and  
setting that to the module like:

vk.setVerse(vk.getVerse() - context);
for(int i = 0;i <= context*2+1;i++) {
	module.setKey(vk.getText());
	if(!module->Error()) {
		// render
	}
	vk.increment();
}

Is this more expensive regarding API calls?


Regards,
Manfred
