Check if current item is undemouse() crash!?!?!?

[ruben.rodrigues]

Hi!

I want to see if the current widget is also under the mouse. I used the function this->mouseGrabber()->underMouse() which gives me a segmentation fault.

then I tried this one:

QWidget *w = new QWidget(this->mouseGrabber());
 
if(w->underMouse()){
   //Do something
}

QWidget *w = new QWidget(this->mouseGrabber());

if(w->underMouse()){
   //Do something
}

To copy to clipboard, switch view to plain text mode 

but it return me false...I believe this should work

Try:

QWidget *w = dynamic_cast<QWidget *>( this->mouseGrabber() );
 
if (w)
{
  if (w->underMouse())
  {
     //Do something
  }
}

QWidget *w = dynamic_cast<QWidget *>( this->mouseGrabber() );

if (w)
{
  if (w->underMouse())
  {
     //Do something
  }
}

Why not just :

if( this->underMouse() ){
   // do something
}

if( this->underMouse() ){
   // do something
}
