Image Buttons

[CrazyEddie]

Hi,

Glad you have something working now.

There is an ImageButton for TaharezLook. The initial I is capitalised though, so "TaharezLook/ImageButton" is what you maybe needed.

Since you have it working with the standard button, obviously you're free to carry on with that

I didn't want to open a new thread as this one is relevent, my problem is that i want to use the button that we created in the tutorial however i can't seem to get the subscribe event syntax correct.

Code: Select all

   pChatContentBox = (CEGUI::MultiLineEditbox*)m_pChatWnd->getChild("ChatContentBox");
   CEGUI::PushButton* pExitButton = (CEGUI::PushButton*)m_pMainWnd->getChild("ExitButton_Game");
   pExitButton->subscribeEvent(CEGUI::PushButton::EventClicked, CEGUI::Event::Subscriber(&GameState::onExitButtonGame, this));

   pQuestPanel = (CEGUI::MultiLineEditbox*)m_pQuestWnd->getChild("QuestPanel");
   m_pQuestWnd->subscribeEvent(CEGUI::FrameWindow::EventCloseClicked, CEGUI::Event::Subscriber(&GameState::onQuestExitButton, this));

   CEGUI::Window *w = CEGUI::WindowManager::getSingleton().loadWindowLayout( "fireballBtn.layout" );
   m_pMainWnd->addChildWindow( w );
   w->setPosition( CEGUI::UVector2( CEGUI::UDim(0.0f,-32.0f), CEGUI::UDim(1.0f,-10.0f) ) );
   w->setVisible( true );
            -------------w->subscribtEvent(CEGUI::PushButton???--------------


there doesn't seem to be a CEGUI::ImageButton::EventClicked or something similar, any ideas (its probably really basic, just kinda starting out with cegui

Hi,

The main way to go here is to get an understanding of how we produce some of these various types within CEGUI. For example, looking in the scheme file for TaharezLook, we have the following lines:

Code: Select all

<FalagardMapping WindowType="TaharezLook/Button"      TargetType="CEGUI/PushButton"  Renderer="Falagard/Button"       LookNFeel="TaharezLook/Button" />
...
<FalagardMapping WindowType="TaharezLook/ImageButton" TargetType="CEGUI/PushButton"  Renderer="Falagard/Button"       LookNFeel="TaharezLook/ImageButton" />

The key information in these lines is the TargetType attribute - in this case CEGUI/PushButton. Now, this is the concrete Window based class that is being used, and this is what provides the event functionality. So, to conclude... In this case you still use CEGUI::PushButton, since this is the core type that the specific types are being bound to. Or to put it another way, "TaharezLook/Button" and "TaharezLook/ImageButton" are just skins over the same old PushButton type.

HTH

Ty sir that made sense, however i believe i tryed that and got the following error:

Code: Select all

error C2661: 'CEGUI::SubscriberSlot::SubscriberSlot' : no overloaded function takes 2 arguments

So i tryed to clear things up a little but got the same error :S :

Code: Select all

   m_pw = CEGUI::WindowManager::getSingleton().loadWindowLayout( "fireballBtn.layout" );
   m_pMainWnd->addChildWindow( m_pw );
   CEGUI::PushButton* pFireball = (CEGUI::PushButton*)m_pMainWnd->getChild("fireballBtn");

   m_pw->setPosition( CEGUI::UVector2( CEGUI::UDim(0.5f,-32.0f), CEGUI::UDim(1.0f,-10.0f) ) );
   m_pw->setVisible( true );
   pFireball->subscribeEvent(CEGUI::PushButton::EventClicked, CEGUI::Event::Subscriber(&GameState::fireBall, this));

Ummm, ok.

What is the full function signature for GameState::fireball - it has to match 'bool function(const CEGUI::EventArgs&)' - and is the 'this' in the subscribe line an instance of GameState?

Ty for your patience. This is what i needed to understand. Works beautifully
