CocosStudio UI组件


按钮UIButton
复选框UICheckBox
滑块UISlider
图片UIImageView
进度条UILoadingBar
纹理文本 UITextAtlas
字体文本 UIText
图片字体文本 UITextBMFont
文本区域 UITextField
布局组件 UILayout
滚动组件 UIScrollView
页面切换组件 UIPageView
列表组件 UIListView
所有控件都继承 UIWidget
可以通过addChild()添加UIWidget类型的节点
可以通过addRender()添加CCNode类型的节点
一、使用方法
1.1 在解决方案中添加项目并添加引用
libCocostudio
libGui
libExtensions
1.2 在项目中引用以下2个头文件
#include "extensions/cocos-ext.h"
#include "ui/CocosGUI.h"
USING_NS_CC;
using namespace ui;
1.3 使用CocosStudio UI编辑器或直接通过代码定义组件对象
二、各组件使用详解
2.1.UIButton
2.1.1 按钮对象的创建
// 创建按钮 button
Button* button = Button::create("cocosui/animationbuttonnormal.png",
"cocosui/animationbuttonpressed.png");
//设置坐标
button->setPosition(Point(widgetSize.width / 2.0f,widgetSize.height / 2.0f));
//添加事件
button->addTouchEventListener(this,toucheventselector(UIButtonTest::touchEvent));
//添加到图层
_uiLayer->addChild(button);
2.1.2 事件处理方法：
void UIButtonTest::touchEvent(Ref *pSender,TouchEventType type)
{ switch (type)
{ case TOUCH_EVENT_BEGAN:
_displayValueLabel->setText(String::createWithFormat("Touch Down")->getCString());
break;
case TOUCH_EVENT_MOVED:
_displayValueLabel->setText(String::createWithFormat("Touch Move")->getCString());
case TOUCH_EVENT_ENDED:
_displayValueLabel->setText(String::createWithFormat("Touch Up")->getCString());
case TOUCH_EVENT_CANCELED:
_displayValueLabel->setText(String::createWithFormat("Touch Cancelled")->getCString());
break;
default:
}

}
2.1.3 使用9Path图片
// Create the button
Button* button = Button::create("cocosui/button.png","cocosui/buttonHighlighted.png");
// open scale9 render
button->setScale9Enabled(true);
button->setCapInsets(Rect(5,5,15,15));
button->setSize(Size(150,70));
2.1.4 实现PressedAction效果
// Create the button

button->setPressedActionEnabled(true);
2.1.5 实现TitleButton
// Create the button with title
Button* button = Button::create("cocosui/backtotoppressed.png","cocosui/backtotopnormal.png");
button->setTitleText("Title Button");
2.2.UICheckBox
2.2.1 添加CheckBox
// Create the checkbox
CheckBox* checkBox = CheckBox::create("cocosui/check_box_normal.png",51); font-family:Arial; font-size:14px; line-height:26px"> "cocosui/check_box_normal_press.png",51); font-family:Arial; font-size:14px; line-height:26px"> "cocosui/check_box_active.png",51); font-family:Arial; font-size:14px; line-height:26px"> "cocosui/check_box_normal_disable.png",51); font-family:Arial; font-size:14px; line-height:26px"> "cocosui/check_box_active_disable.png");
checkBox->setPosition(Point(widgetSize.width / 2.0f,51); font-family:Arial; font-size:14px; line-height:26px">
checkBox->addEventListenerCheckBox(this,checkboxselectedeventselector(UICheckBoxTest::selectedEvent));
_uiLayer->addChild(checkBox);
2.2.2 处理用户选中事件
void UICheckBoxTest::selectedEvent(Ref* pSender,CheckBoxEventType type)
{
switch (type)
{
case CHECKBOX_STATE_EVENT_SELECTED:
_displayValueLabel->setText(String::createWithFormat("Selected")->getCString());

slider->setPosition(Point(widgetSize.width / 2.0f,widgetSize.height / 2.0f/* + slider->getSize().height * 2.0f*/));
slider->addEventListenerSlider(this,sliderpercentchangedselector(UISliderTest::sliderEvent));
_uiLayer->addChild(slider);
2.3.2
void UISliderTest::sliderEvent(Ref *pSender,SliderEventType type)
{
if (type == SLIDER_PERCENTCHANGED)
Slider* slider = dynamic_cast<Slider*>(pSender);
int percent = slider->getPercent();
_displayValueLabel->setText(String::createWithFormat("Percent %d",percent)->getCString());
}
2.3.3
// Create the slider
slider->loadBarTexture("cocosui/sliderTrack2.png");
slider->loadProgressBarTexture("cocosui/slider_bar_active_9patch.png");
slider->setScale9Enabled(true);
slider->setCapInsets(Rect(0,0));
slider->setSize(Size(250.0f,19));

三、在CocosStudio的UI编辑器中获取组件对象
3.1使用UI编辑器
3.2导出UI文件
3.3在Cocos2d-x中加载UI文件
3.4获取UI层中的子对象
四、UI组件详解
4.1使用UIButton
4.1.1 载入UIButton文件
bool UIButtonTest_Editor::init()
if (UIScene_Editor::init())
_layout = static_cast<Layout*>(cocostudio::GUIReader::getInstance()->widgetFromJsonFile("cocosui/UIEditorTest/UIButton_Editor/UIButton_Editor_1.json"));
