Signal connect problem

Hi all,

I have an strange problem connecting signals to slots. I have the next code:


Container* container = root->findChild<Container*>("timeline_container");
m_pForeignWindow = (ForeignWindowControl*)(container->at(0));


// m_pForeingWindow is not null here


bool success = connect(m_pForeignWindow,
                             SIGNAL(windowAttached(screen_window_t,const QString&,const QString&)),
                             SLOT(onWindowAttached(screen_window_t,const QString&,const QString&)));


// success == true here

success = QObject::connect(m_pForeignWindow,
                    SIGNAL(touch(TouchEvent *)),
                    SLOT(onTouch(TouchEvent *)) );


//success == false here


Searching with the debugger I obtained the next message:


Object::connect: No such signal bb::cascades::ForeignWindowControl::touch(TouchEvent *) 


but this signal exists for all VisualNode objects... What am I doing wrong??

Re: Signal connect problem

Any cascade specific classes have to be speficially called out within connect.  Try

Re: Signal connect problem

When I try this:


bool success = QObject::connect(m_pForeignWindow,
                                                             SIGNAL(touch(bb::cascades::TouchEvent *)),
                                                             SLOT(onTouch(bb::cascades::TouchEvent *)) );


The IDE shows an error:

Signal/Slot "ForeignWindowControl.touch(bb::cascades::TouchEvent *)" is not defined.


In the 'include' section I have:


#include <bb/cascades/ForeignWindowControl>
#include <bb/cascades/TouchEvent>


using namespace bb::cascades;

Re: Signal connect problem

See if it actually compiles.  The IDE in the current beta is notorious for incorrectly reporting those errors, so I suggest turning them off.
