サンプル

cocos2d::ui::EditBox* _editPassword = ui::EditBox::create(Size(visibleSize.width/3, 30), "extensions/orange_edit.png");
_editPassword->setPosition(Vec2(origin.x+visibleSize.width/2, origin.y+visibleSize.height/2));
_editPassword->setFont("American Typewriter", 16);
_editPassword->setFontColor(Color3B::GREEN);
_editPassword->setPlaceHolder("Password:");
_editPassword->setMaxLength(6);
_editPassword->setInputFlag(ui::EditBox::InputFlag::PASSWORD);
_editPassword->setInputMode(ui::EditBox::InputMode::SINGLE_LINE);
_editPassword->setText("初期文字");
addChild(_editPassword);

文字取得

_editPassword->getText();

イベント付きサンプル

#include "ui/CocosGUI.h"
class HelloWorld : public cocos2d::Layer, cocos2d::ui::EditBoxDelegate
{
public:
   static cocos2d::Scene* createScene();
   virtual bool init();
   CREATE_FUNC(HelloWorld);
private:
   virtual void editBoxEditingDidBegin(cocos2d::ui::EditBox* editBox);
   virtual void editBoxEditingDidEnd(cocos2d::ui::EditBox* editBox);
   virtual void editBoxTextChanged(cocos2d::ui::EditBox* editBox, const std::string& text);
   virtual void editBoxReturn(cocos2d::ui::EditBox* editBox);
};

    return true;
}

イベントを取得したいときのみEditBoxDelegateとsetDelegate(this)を追加する

Extensionは非推奨

cocos2d-x ui::EditBoxを使う

setInputMode(EditBox::InputMode::NUMERIC);
