C++ (Cpp) colX Examples

Example #1

File: ofxGridSystem.cpp Project: RobertoMalatesta/ofxSoso

//Method for accessing grid positions.
//Basically, this returns an ofxGridSystemArray, which also has an overloaded [] operator.
//Usage: grid[2][2] where this will return an ofVec3f for the column 2 and 2 baselines down from top of page.
ofxGridSystemArray ofxGridSystem::operator[](int iColumn)
{
    ofxGridSystemArray array;
    array.x = colX(iColumn);
    array.leading = leading;
    array.height = height;
    
    return array;
}
