Error when using "subscribeEvent()"

[Lucky_Luciano]

Hi,

I'm playing around with CEGUI these days and I already used CEGUI in another test-program without a problem but now I've encountered this problem:
Is use this piece of code in my createScene() method in an Ogre3D application:

Code: Select all

CEGUI::WindowManager& wmgr = CEGUI::WindowManager::getSingleton();
        wmgr.getWindow((CEGUI::utf8*)"QuitButton")
         ->subscribeEvent(CEGUI::PushButton::EventClicked,
CEGUI::Event::Subscriber(&ActionBar::handleQuit, this));


and I get this error when compiling the program:

Code: Select all

d:\Ogre\ogrenew\Samples\MapEditor\MapEditor.cpp(62):
error C2661: 'CEGUI::SubscriberTemplate<Ret,Args>::__ctor' :
 no overloaded function takes 2 arguments
        with
        [
            Ret=bool,
            Args=const CEGUI::EventArgs &
        ]
        and
        [
            Ret=bool,
            Args=const CEGUI::EventArgs &
        ]



Very wierd, cause I used the exact line of code in another program before (also in the createScene method).
I fear I don't have enough experience with CEGUI to know what's going on, hence the question

Thanks in advance!

Hi,

What's the full prototype / siganture for the ActionBar::handleQuit method?

CE.

This is the class ActionBar:

Code: Select all

class ActionBar
{
private:
protected:
   CEGUI::Window*   mWindow;
public:
         ActionBar();
         ~ActionBar();
   CEGUI::Window*   getWindow() { return mWindow; }
   bool      handleQuit(const CEGUI::EventArgs& e);
};


This is the implementation of handleQuit

Code: Select all

bool ActionBar::handleQuit(const CEGUI::EventArgs& e)
{
return true;
}

Is your createScene method mentioned in the original post a member of the ActionBar class? It doesn't have to be, but what you do need to ensure is that you're passing a corrent object pointer.

[code]
CEGUI::Event::Subscriber(&ActionBar::handleQuit, this);[/quote]

The 'this' whithin the above construct needs to be an instance of the class which contains the bound member. If you have no instance of the object at this point, then either a free function, or a static member function will need to be used.

HTH

Great, I found what I did wrong.
Apparantly I miss-understood the function: I thought the "this" stood for an instance where the function createScene() is declared
I replaced "this" with an instance of ActionBar and everything works perfect now.

Thanks for the help Eddie!
