(CEGUI)如何创建控件 ------单选按钮RadioButton

//自己定义一个窗口
 Window* MyWindow = winMgr.createWindow("TaharezLook/FrameWindow","MyWindow");
 MyWindow->setText("Demo7  -- MyWindow");
 MyWindow->setProperty("CloseButtonEnabled","False");
 MyWindow->setPosition(UVector2(cegui_reldim(0.0f),cegui_reldim(0.3)));
 MyWindow->setSize(UVector2(cegui_reldim(0.3f),cegui_reldim(0.3f)));
 Window* root = winMgr.getWindow("root");
 root->addChildWindow(MyWindow);

//创建单选按钮

 RadioButton* op1 = static_cast<RadioButton*>(winMgr.createWindow("TaharezLook/RadioButton","option1"));

//设置TEXT
 op1->setText("Option 1");

//设置ID
 op1->setID(1);

//设置大小和位置
 op1->setPosition(UVector2(cegui_reldim(0.1f),cegui_reldim(0.1f)));
 op1->setSize(UVector2(cegui_reldim(0.4f),cegui_reldim(0.1f)));
 MyWindow->addChildWindow(op1);

 

 

 RadioButton* op2 = static_cast<RadioButton*>(winMgr.createWindow("TaharezLook/RadioButton","option2"));
 op2->setText("Option 2");
 op2->setID(2);
 op2->setPosition(UVector2(cegui_reldim(0.1f),cegui_reldim(0.2f)));
 op2->setSize(UVector2(cegui_reldim(0.4f),cegui_reldim(0.1f)));
 MyWindow->addChildWindow(op2);
 
 RadioButton* op3 = static_cast<RadioButton*>(winMgr.createWindow("TaharezLook/RadioButton","option3"));
 op3->setText("Option 3");
 op3->setID(3);
 op3->setGroupID(1);
 op3->setPosition(UVector2(cegui_reldim(0.1f),cegui_reldim(0.4f)));
 op3->setSize(UVector2(cegui_reldim(0.4f),cegui_reldim(0.1f)));
 MyWindow->addChildWindow(op3);
 
 RadioButton* op4 = static_cast<RadioButton*>(winMgr.createWindow("TaharezLook/RadioButton","option4"));
 op4->setText("Option 4");
 op4->setID(4);

//设置GroupID，如果不设置就是默认为0
 op4->setGroupID(1);
 op4->setPosition(UVector2(cegui_reldim(0.1f),cegui_reldim(0.5f)));
 op4->setSize(UVector2(cegui_reldim(0.4f),cegui_reldim(0.1f)));
 //op4->
 MyWindow->addChildWindow(op4);

 

 

//设置回调函数

WindowManager::getSingleton().getWindow("option1")->subscribeEvent(RadioButton::EventSelectStateChanged,Event::Subscriber(&Demo7Sample::handleOption,this));
 WindowManager::getSingleton().getWindow("option2")->subscribeEvent(RadioButton::EventSelectStateChanged,Event::Subscriber(&Demo7Sample::handleOption,this));
 WindowManager::getSingleton().getWindow("option3")->subscribeEvent(RadioButton::EventSelectStateChanged,Event::Subscriber(&Demo7Sample::handleOption,this));
 WindowManager::getSingleton().getWindow("option3")->subscribeEvent(RadioButton::EventSelectStateChanged,Event::Subscriber(&Demo7Sample::handleOption,this));

 

 

//回调函数

bool Demo7Sample::handleOption(const CEGUI::EventArgs& e)
{
 using namespace CEGUI;

*getSelectedButtonInGroup()：获得同个组的那个选中的按钮
 uint optionid = static_cast<RadioButton*>(static_cast<const WindowEventArgs&>(e).window)->getSelectedButtonInGroup()->getID();

 switch(optionid)
 {
 case 1:
  MessageBox(NULL,"1","",MB_OK);
  break;
 case 2:
  MessageBox(NULL,"2","",MB_OK);
  break;
 case 3:
  MessageBox(NULL,"3","",MB_OK);
  break;
 case 4:
  MessageBox(NULL,"4","",MB_OK);
  break;
  
 }
 return true;
}
