I installed everything in order to just look around and will probably trim it down later.
Code:
rpm -qa | grep qt
qt-3.3.3-8
qt-config-3.3.3-8
qt-devel-3.3.3-8
qt-ODBC-3.3.3-8
qt-designer-3.3.3-8
qt-PostgreSQL-3.3.3-8
qt-MySQL-3.3.3-8
This is what I find. I suppose you could look for the qt-designer-3.3.3-8 rpm on your install disk and install that. I do not think that add/remove programs gives you access to all of the rpms that are available on the install disks.
