Hi,
I have a program that make use of QT4 as the GUI. During startup, it reads in a configuration file and creates a series of GUI components that are inherited from QT GUI classes (QFileDialog, etc.). However, on my desktop machine (Pentium D 820 CPU running Windows XP sp2), the startup is very slow. Tracking into the source I found that it is due to slow constructions and operations of the inherited QT classes. I have built the program with QT
4.1.4, 4.2.2 and 4.2.3, and they have the same problem. On another desktop machine with same hardware and same operating system, the program has the same problem. However, on two laptop computers with the same OS, the program has no problem. I have also tried to run the QT demos bundled with the QT source code on the problematic desktop machine, and the demos all work fine. So here is a strange problem. It seems that my program (and also QT) have troubles on a particular hardware/software configuration. Does anybody have similar experiences before? How can I fix it? Thank you very much!
Eric
