[Qt-interest] Moving through a QListView using D-Bus

[Per Christian B. Viken]

Hi.

I'm currently using Qt4 with Ruby to see if I can build a small media  
launcher I can use via my remote. It basically displays a giant  
QListView on the entire screen, using a QDirModel to get files and  
folders. I figured that the easiest way to make LIRC and the  
application talk was using D-Bus, but if another solution works  
better, I'm open to suggestions.

The problem is that I can't figure out a way to move the current  
selection up and down without using the mouse or keyboard.

So far I've tried faking a keypress, emitting a keyReleaseEvent with  
the correct event (Down released), but this doesn't seem to work.

Also tried:
curIndex = listView.currentIndex
listView.setCurrentIndex(curIndex.child(curIndex.row+1, 0))
which is executed, but only seems to deselect that which was selected  
with the mouse already. When nothing is selected, nothing happens.

(I'm not very familiar with Qt at the moment, but I have searched  
through the API without finding much that works. Figured I should try  
with Ruby first, since I already know that, and avoid fighting with C+ 
+ and Qt at the same time. Then learn C++ later on.)
