We use buffered imput and we are starting to use mygui.
We put de funcion new delegates and it is problematic, we obtend the next mistake:

i probe a lot things and i have not idea.

Somebody can help me????
thanks.

I already answered you same question http://www.ogre3d.org/phpBB2addons/viewtopic.php?t=8367!

yes, but i have to use other form to solve, and i want to use the funcion that is into the MyframeListener, and it is the problematic.

Looks like you don't understand how eventMouseButtonClick and all gui events work. eventMouseButtonClick calls your delegate every time when button was clicked. So you delegate is sth that printing "Hello, world!" for example or doing some other useful stuff.
So in your case you should add new member function to MiFrameListener with specific to event signature (see eventMouseButtonClick declaration). For examplevoid handleButtonClick(MyGUI::WidgetPtr _sender)
{
_sender->setCaption("Button was clicked");
}And then change you livi with event tobutton->eventMouseButtonClick = MyGUI::newDelegate(&mFrameListener, &MiFrameListener::handleButtonClick);
mFrameListener also need to have type MiFrameListener, not ExampleFrameListener because ExampleFrameListener don't have your functions.MiFrameListener* mFrameListener;

i probe this in my "new" code:

the compiler doesn't give me problems, but when i execute it, y click over the button and nothing chages.
?¿?¿?¿

thanks.

Read this http://www.ogre3d.org/wiki/index.php/MyGUI_quickstart
Where' all your mGUI->inject*** functions? You must have them if you want to use gui.

the problems continues, and i do every thing like the wiki says:


mGUI = new MyGUI::Gui();
mGUI->initialise(mWindow,"core.xml","General");
button = mGUI->createWidget<MyGUI::Button>("Button", 100, 100, 300, 26, MyGUI::ALIGN_RIGHT, "Main");
button->eventMouseButtonClick = MyGUI::newDelegate(this, &Myclass::mousePressed);


bool CLASS::mousePressed( const OIS::MouseEvent &arg, OIS::MouseButtonID id )
{
mGUI->injectMousePress(arg, id);
//...
}




the mistake::

error C2784: 'MyGUI::delegates::IDelegate1<TP1> *MyGUI::delegates::newDelegate(void (__cdecl *)(TP1))' : no se pudo deducir el argumento de plantilla para 'void (__cdecl *)(TP1)' desde 'bool (__thiscall Myclass::* )(const OIS::MouseEvent &,OIS::MouseButtonID)'


i'm so desesperate, i am not be able to do this my self, i need to see some example code of my gui.

thanks.

there's some demos coming with MyGUI source

well, i'm here again,
now i have some control for the mouse events, there is only one problem, i don't see the arrow of the mouse. i mean, i see but it doesn't move.
the code is the same and a put you a capture:

Sorry, but you need to learn how to use OIS with Ogre. Read some tutorials or learn from source code.
