Usages of cceditbox text input boxes in cocos2d-x _c language

Text input Box This is something that you can always use, no matter what game you do, and today we're going to see how this thing is used. The text input box is also part of the expansion library, so you know how to do it. When the user wants to enter the content in the text box, this series of procedures we need some function call to get what we want, the class containing these functions needs to implement cceditboxdelegate this interface, let's look at how to use the specific.

#ifndef __helloworld_scene_h__ #define __HELLOWORLD_SCENE_H__ #include "cocos2d.h"//need to include an extension library #include "cocos-ext.h" usi
ng namespace Cocos2d;
using namespace Cocos2d::extension;
Use Cceditbox must inherit from Cceditboxdelegate interface, implement some of its functions class Helloworld:public cocos2d::cclayer,public cceditboxdelegate { Public://Here ' s a difference.

  Method ' init ' in cocos2d-x returns BOOL, instead of returning ' IDs ' in Cocos2d-iphone virtual bool init ();

  There ' s no ' id ' in CPP, so we recommend returning the class instance pointer static cocos2d::ccscene* scene ();

	Implement the "Static node ()" Method manually Create_func (HelloWorld);

	The function to implement is the following//when the keyboard pop-up edit box gets the focus, the virtual void Editboxeditingdidbegin (cceditbox* editbox) is invoked;

	Call virtual void Editboxeditingdidend (cceditbox* editbox) when the keyboard disappears when the edit box loses focus;

	Invoke virtual void editboxtextchanged (cceditbox* editbox, const std::string& text) when the text of the edit box changes.

The virtual void Editboxreturn (cceditbox* editbox) is invoked when the return key is pressed or when an area other than the keyboard is clicked; Private:ccsize m_size;
Cceditbox * EditBox;
