CPP / JUCE Audioprogramming Framework - Array of Sliders not working - Single Slider works

i have some problems coding a custom component. However i tried with a single slider instance like this:

ScopedPointer<Slider> slider001;
ScopedPointer<Slider> slider002;

slider001->setBounds  (0        ,       sliderY , sliderWidth, sliderHeight );
slider002->setBounds  (0+ 1*sliderX ,   sliderY , sliderWidth, sliderHeight );

addAndMakeVisible (slider001 = new Slider ("new slider"));
addAndMakeVisible (slider002 = new Slider ("new slider"));

everything works as expected however you know people are lazy so i tried using an array:

ScopedPointer<Slider> sliderArray[128];


  for(int i=0; i==128; i++) 
{sliderArray[i]->setBounds  (0   +i  *sliderX    ,       sliderY , sliderWidth, sliderHeight );}


}                                     


for(int i=0; i==128; i++) 
{  
    addAndMakeVisible (sliderArray[i]= new Slider ("Value"));
    sliderArray[i]->setRange (sliderMinimumRange, sliderMaximumRange, sliderRangeStepsize );
    sliderArray[i]->setSliderStyle (Slider::LinearBarVertical);
}

now the screen just stays blank. i tried replacing single slider elements with an array and iterating through them and i'm completely clueless where to start to fix this behaviour.

thank you

Your problem lies in the way you have configured your loops:

for(int i=0; i==128; i++) {}

This can be interpreted as:

"set i to 0, and while i == 128, do {} then i++"

What you probably wanted to write was:

for(int i=0; i<128; i++) {}
