Hello Developers,

Is there any way to make EditBox accept alphabets only ?
This is my code -

this->_editBox = ui::EditBox::create(Size(230, 93), "PMHomeScene/profile_bar.png");
this->_editBox->setFontName("fonts/Marker Felt.ttf");
this->_editBox->setInputMode(EditBox::InputMode::SINGLE_LINE);
this->_editBox->setPosition(Vec2(origin.x + visibleSize.width/2, origin.y + visibleSize.height*0.6));
this->_editBox->setFontColor(Color3B::BLACK);
this->_editBox->setText(playerName.c_str());
this->_editBox->setPlaceholderFontColor(Color3B::BLACK);
this->_editBox->setMaxLength(7);
this->_editBox->setScale(0.0f);

#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
this->_editBox->setReturnType(ui::EditBox::KeyboardReturnType::DONE);
#else
 this->_editBox->setReturnType(ui::EditBox::KeyboardReturnType::SEND);

 #endif
 this->_editBox->setDelegate(this);
 this->_editBox->touchDownAction(this->_editBox, Widget::TouchEventType::ENDED);
 this->_popUpBox->addChild(this->_editBox);

Please guide me to achieve Alphabets only in EditBox.
This becomes essential when we use EditBox to input player names.
