How to dynamically load different xml settings files

[olivercrush]

Hi,

I would like to know how I can dynamically change the xml settings file. I would basically like to change some surfaces and sources when I press a button. Is there a way to easily do that ? I saw that there is a preset system too but I'm not really sure what it does and how it works.

Thank you in advance for your response, you did a great job on this project !

You mean dynamically load another xml file? There is the function ofxPiMapper::loadProject(std::string filename). Try that. There might be issues, since the ofxOMXPlayer in the background might not unload video files properly and it would eat up memory. If you use it with images, should work fine. Got to do something with this OMX player...

Yes I tried calling loadProject in my ofApp.cpp, but it freezes everything and I have to reboot my pi. I can't even get back to the command interface to see the debug messages so it's hard to tell where exactly the problem occurs. And I don't even use videos in my mapping, there are just images

Yes, I guess that is a valid issue. The thing with pressets is that you can store multiple projects in one xml file. You could try that approach. You just have to add another <surfaces>...</surfaces> block after the one that is there. That is for now.

Oh ok thanks, I will look into it. I guess I can switch between presets with the setPreset() method ?

[kr15h]

Yes.

is possible to have this "function" in the example? (so if i press 7 i load preset 1, 8 load preset 2 ecc..?)
thx

Here, I can give you my ofApp's keyPressed method for an example. You just have to have several surfaces which contains your configurations in your ofxpimapper.xml

void ofApp::keyPressed(int key) {

	switch (key) {
		case 'q':
			mapper.setPreset(0);
			break;

		case 'w':
			mapper.setPreset(1);
			break;

		case 'e':
			mapper.setPreset(2);
			break;

		case 'r':
			mapper.setPreset(3);
			break;

		case 't':
			mapper.setPreset(4);
			break;

		case 'y':
			mapper.setPreset(5);
			break;

		case 'u':
			mapper.setPreset(6);
			break;

		case 'i':
			mapper.setPreset(7);
			break;

		case 'o':
			mapper.setPreset(8);
			break;

		case 'p':
			mapper.setPreset(9);
			break;

		case 'a':
			mapper.setPreset(10);
			break;

		case 's':
			mapper.setPreset(11);
			break;

		default:
			mapper.keyPressed(key);
			break;
	}
	usleep(10);
}

Yes, this is how it is meant to be. One can override internal ofxPiMapper shortcuts.

yes... a feature could be to have a "config file" in witch are defined the keys and could be reconfigured. thx Pietro Capriata http://www.pietrocapriata.me CONFIDENTIALITY DISCLAIMER Le informazioni contenute in questo messaggio di posta elettronica e negli allegati sono riservate e confidenziali e ne sono vietate la lettura, l'uso, la copia, la comunicazione e la diffusione in qualunque modo eseguite.

You can also take a look at the example_pocketvj ofApp.cpp and use that to remap your keys. But I would prefer the config file solution proposed by @pietrondo myself.
