[Paraview] Current Version of Qt for CVS HEAD

[OSHIMA Takuya]

Hi,

I had the same problem with Qt 4.2.3 when I tried to compile the 3.3
CVS head with VS2008. It looks like it's been fixed after I pulled
this snippet from Qt4.3.3 and appended at around the line 85 of
paraview-qt-win-opensource-4.2.3/src/corelib/tools/qhash.h:

template <typename T1, typename T2> inline uint qHash(const QPair<T1, T2> &key)
{
    uint h1 = qHash(key.first);
    uint h2 = qHash(key.second);
    return ((h1 << 16) | (h1 >> 16)) ^ h2;
}

By the way, when I used Qt 4.3.3 instead, If I click the VCR Play
button it just grayed out and doesn't change to the Pause button. So I
have to play all the sequence of the animation until the end. I have
this problem also under Linux and Mac OS X 10.5.2 (Intel). Is this a
known issue, or does anyone have a solution?

Regards,
Takuya
