Button Problems

AlexL · Post by **AlexL** » Tue Mar 09, 2004 7:30 am

I've been having even more problems

Though some of the past problems where figured out on my own, but I'm stuck on this one... I have created a button and an event for when the button is pushed, and it compiles just fine, but when I run the program and click on the button nothing happens at all

Would anyone mind taking the time to help me on this problem?

Code: Select all

guienv -> addButton(rect<s32>(10,10,60,35), 0, 101, L"Exit Demo");

Code: Select all

bool RBGame::OnEvent(SEvent event)
{
	if (event.EventType == EET_GUI_EVENT)
	{
		s32 id = event.GUIEvent.Caller->getID();
		switch(id)
		{
		case 101:
			if (event.GUIEvent.EventType == gui::EGET_BUTTON_CLICKED)
			{
				device -> closeDevice();
			}
		}
	}
	return false;
}

is your class RBGame declared as an IEventReceiver??....did you write "this" for the receiver in your createDevice - call???

I've decided to post all of the code for the project since that might make it easier for the problem to be solved. Thanks in advance.

Hi,

when you call createDevice you have to use a pointer to your EventReceiver as last parameter or use setEventReceiver instead. I think you forgot this.

Just make an EventReceiver with

Code: Select all

RBEventReceiver receiver;

and initialize your device with

Code: Select all

IrrlichtDevice* device = createDevice(video::EDT_DIRECTX9, dimension2d<s32>(800,600), 16, false, true, &receiver);

That should work.
