Cocos2d-x UI Development Cccontrolslider control classes use instances _c languages

For some configuration when a control is used, see article: Control class-cccontrolbutton for UI development. Here only the source code, the inside of the comments on the control of the use of a detailed description.

BOOL Helloworld::init () {bool BRet = false; do {cc_break_if (!

		Cclayer::init ());
		Sets a label Cclabelttf * title = cclabelttf::create ("Slider value = 0.00", "Arial", 32).
		Title->setposition (CCP (240,200));

		The tag is set to 1 for easy access to This->addchild (title,0,1); These three pictures are the bottom, the progress bar, the control button Cccontrolslider * slider = cccontrolslider::create ("Slidertrack.png", "Sliderprogress.png", "SL

		Iderthumb.png ");
		Setting the maximum minimum value of the slider slider->setmaximumvalue (100);
		Slider->setminimumvalue (0); Add an event listener function to the slider slider->addtargetwithactionforcontrolevents (this,cccontrol_selector HelloWorld::
		valuechanged), cccontroleventvaluechanged);
		Set Position Slider->setposition (CCP (240,160));

		This->addchild (slider); The use of cccontrolslider to achieve the blood bar, as long as the third control button to be transparent, it will appear to be the blood volume of cccontrolslider * Slider2 = Cccontrolslider::create ("
		Slidertrack.png "," Progress.png "," sliderthumb2.png ");
		The value slider2->settouchenabled (false) which is not considered to be changed by the following function; Slider2->setmaximumvalUE (100);
		Slider2->setminimumvalue (0);
		You can add an event handler function to change its value slider2->setvalue (100) In the event handler function;
		Slider2->setposition (CCP (240,100));

    This->addchild (SLIDER2);
  BRet = true;

  while (0);
return bRet;  }//Note This function needs to pass in two parameter types void helloworld::valuechanged (Ccobject * psender,cccontrolevent controlevent) {Cccontrolslider *
	slider = (Cccontrolslider *) Psender;
	Cclabelttf * title = (Cclabelttf *) This->getchildbytag (1); When using Cclabelttf, try not to change its contents, this is for the sake of simplicity title->setstring (Ccstring::createwithformat ("Slider value =%0.02f",
 Slider->getvalue ())->getcstring ()); }
