OfxParameterSuiteV1::paramGetValue
— Gets the current value of a parameter,
#include "ofxParam.h"
OfxStatus(*paramGetValue)( | OfxParamHandle paramHandle, |
...) ; |
This gets the current value of a parameter. The varargs ... argument needs to be pointer to C variables of the relevant type for this parameter. Note that params with multiple values (eg Colour) take multiple args here. For example...
OfxParamHandle myDoubleParam, myColourParam; ofxHost->paramGetHandle(instance, "myDoubleParam", &myDoubleParam); double myDoubleValue; ofxHost->paramGetValue(myDoubleParam, &myDoubleValue); ofxHost->paramGetHandle(instance, "myColourParam", &myColourParam); double myR, myG, myB; ofxHost->paramGetValue(myColourParam, &myR, &myG, &myB);
