[Qt-interest] QRect::contains is lying to me

[Paul England]

Hello:

This is a little irksome.  I'm basically storing geometries of QWidgets
in a std::map.  When a widget moves, before dropping it I make sure it's
not going to be on top of another QWidget.  Sounds easy enough, right? 
I'm checking to make sure the geometries of the QObjects don't collide
with QRect::contains().  It keeps telling me they don't when they
clearly do.  Am I missing something?  Here's the code:

std::map<QWidget*, QRect> geometries;

int drag_dialog::geometry_okay( QWidget* self, const QRect& rect ) const
{
    map<QWidget*, QRect>::const_iterator it;
    for ( it = geometries.begin(); it != geometries.end(); it++ ) {

        if ( (*it).first == self ) {
            continue;
        }

        if ( rect.contains( (*it).second ) ) {
            printf( "Bubuuu... no dice\n" );
            return 0;
        } else {
            printf( "%d,%d -> %d,%d does not conflict with %d,%d ->
%d,%d\n",
            rect.topLeft().x(), rect.topLeft().y(),
rect.bottomRight().x(), rect.bottomRight().y(),
            (*it).second.topLeft().x(), (*it).second.topLeft().y(),
(*it).second.bottomRight().x(), (*it).second.bottomRight().y() );
        }
    }

    return 1;
}

Output I got when I clearly dropped one widget on another:
9,8 -> 109,254 does not conflict with 0,0 -> 99,245

Thanks.
