Qt custom look and feel?

阅读更多关于 Qt custom look and feel?

问题 can I force my Qt application to use different look and feel just like it is done in KDE ? 回答1: You can always change styles of widgets using QApplication::setStyle.

In main.cpp do something like this #include <QPlastiqueStyle> int main(int argc, char *argv[]) { [...] QApplication::setStyle(new QPlastiqueStyle()); } This way your application will alwyas look the same on different OS. In my opinion Plastique looks better under windowsXP/2000

To my knowledege, I do not explicity set the look-and-feel of my applet. Should I be doing so to avoid this inconsistent behavior? 回答1: Please elaborate what you mean by "display". A different screen
