If the answer is "no", we need to look further into this. Official answer to this question from Trolltech: <QUOTE> I checked with Qt support experts here in Redwood City and they confirmed that Qt4.x is forward binary compatible with previous versions, i.e. a program written for Qt4.2 will run with no problem on subsequent Qt4.2+n releases. (f.ex. Qt4.3 and Qt4.4). However, a Qt4.4 program will not necessarily automatically runs on Qt4.3 or Qt4.2, especially if the new program takes advantage of newer functionality of a later release. The compatibility is at major release level, i.e. 4.x and so all sub-releases like 4.x.y are compatible as well, obviously. </QUOTE> --Stefan -- Stefan Teleman Sun Microsystems, Inc.
