Subcrition event woes

[Ninja]

Hi guys

looking at the demo's etc

added a exit button on my new app and it has given me some errors on compile

any ideas on how to fix this heres the button code

Code: Select all

 PushButton* btn = static_cast<PushButton*>(winMgr.createWindow("TaharezLook/Button", "Quit"));
    sheet->addChildWindow(btn);
    btn->setMaximumSize(Size(1.0f, 1.0f));
     btn->setPosition(Point(0.001f, 0.95f));
    btn->setSize(Size(0.1f, 0.035f));
    btn->setText("Exit");
    subscribeEvent(PushButton::EventClicked, Event::Subscriber(&main::handleQuit, this));

and heres the errors

error C2653: 'SDL_main' : is not a class or namespace name
error C2065: 'handleQuit' : undeclared identifier
error C2673: 'SDL_main' : global functions do not have 'this' pointers
error C3861: 'subscribeEvent': identifier not found, even with argument-dependent lookup

TIA

SDL has a main makro, which replaces the entry function int main(argc..., argv...) with one of it's own "callbacks", as SDL has it's own main function.

To make it short: Rename your main class to something else, e.g. Main, oder TheMain, or whatever

Thanks for the reply tried what you suggested and am getting

error C2673: 'MainUI' : global functions do not have 'this' pointers
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 &
]
error C3861: 'subscribeEvent': identifier not found, even with argument-dependent lookup

any ideas where i messed up ?

Sorry, I can't help you with this problem as I'm using Lua, this is up to a CEGUI pro

These all look like basic coding syntax errors.

error C2673: 'MainUI' : global functions do not have 'this' pointers

You can't use 'this' in a global function. Either move this code to an class method or pass something other than 'this'.

error C2661: 'CEGUI::SubscriberTemplate<Ret,Args>::__ctor' : no overloaded function takes 2 arguments

Check that your definition of handleQuit exactly matches the required definition. I've made this mistake a couple of times recently myself when I forgot to declare the EventArgs & argument as const.

error C3861: 'subscribeEvent': identifier not found, even with argument-dependent lookup

subscribeEvent is a member function of a CEGUI class. In the code you posted above just add btn->.

Thanks for the replies

it compiles fine now

but the subscribeEvent

doesnt seem to be passed ie on pressing the exit button nothing happens

any ideas ?

TIA

Sorry to steal you topic but I found it useless to start a new topic when I have almost the same problem as you have. I also get

Code: Select all

1>.\Lesson1.cpp(231) : error C2673: 'WinMain' : global functions do not have 'this' pointers
1>.\Lesson1.cpp(231) : error C2661: 'CEGUI::SubscriberTemplate<Ret,Args>::SubscriberTemplate' : no overloaded function takes 2 arguments
1>        with
1>        [
1>            Ret=bool,
1>            Args=const CEGUI::EventArgs &
1>        ]

What did you pass instead of this, I can't figure that out.

error C2673: 'WinMain' : global functions do not have 'this' pointers

this says it all.

Just omit the instance pointer for static functions

I fixed it now, rewrote some of the code to make it look better and put itin a class. Now it works fine.
