Hi all,
Ok, was kind of sick of this waiting time so I've rebuild amarok 1.4.8 with
only few changes on *contextbrowser.cpp* :
- line 1141 to 1143, uncomment :
if( b->currentPage() != b->m_contextTab )
return;
- line 1231 & 1240, comment out the #if #endif thing, now looks like :
//#if 0
if( BrowserBar::instance()->currentBrowser() != this )
{
debug() << "current browser is not context, aborting
showCurrentTrack()" << endl;
m_dirtyCurrentTrackPage = true;
m_currentTrackPage->set( QString( "<html><body><div
class='box-body'>%1</div></body></html>" )
.arg( i18n( "Updating..." ) ) );
return;
}
//#endif
I don't know why this feature were disabled because it's exactly what i
needed <:o)
Now when I change or rate a song, There is NO hanging time at all, at least
when the contextView isn't shown
And that makes the whole thing much much more usable here !
Thanks for this great program
Simon
