[fixed] EditBox crashbug

[sudi]

Edit: Irrlicht 1.5

The EditBox doesn't remove its focus in the guiEnvironment after it is removed from the scenegraph.

Compile the following code and select the editbox. Then hit enter twice.

If u uncomment "device->getGUIEnvironment()->setFocus(NULL);" it doesn't crash.

Code: Select all

#include <irrlicht.h>

irr::IrrlichtDevice *device;

irr::gui::IGUIElement* rem;

class events : public irr::IEventReceiver
{
public:
    bool OnEvent(const irr::SEvent& event)
    {
        switch(event.EventType)
        {
            case irr::EET_GUI_EVENT:
                switch(event.GUIEvent.EventType)
                {
                    case irr::gui::EGET_EDITBOX_ENTER:
                        rem = device->getGUIEnvironment()->getRootGUIElement()->getElementFromId(555, true);
                        return true;
                        break;
                }
                break;
        }
        return false;
    }
};

int main(int argc, char* argv[])
{
    rem = NULL;

    device = irr::createDevice(irr::video::EDT_OPENGL, irr::core::dimension2d<irr::s32>(640,480));

    device->setEventReceiver(new events);

    device->getGUIEnvironment()->addEditBox(L"TEST", irr::core::rect<irr::s32>(100,100,200,150), true, NULL/*device->getGUIEnvironment()->addWindow(irr::core::rect<irr::s32>(50,50,500,350))*/, 555);

    while (device->run())
    {
        device->getVideoDriver()->beginScene(true, true, irr::video::SColor(255,0,0,0));

        device->getGUIEnvironment()->drawAll();

        device->getVideoDriver()->endScene();

        if(rem)
        {
            //device->getGUIEnvironment()->setFocus(NULL);
            rem->remove();
            rem = NULL;
        }

    }

    device->drop();
    return 0;
}

It was sending events to a null parent, this is now fixed in trunk.
