| Abstract: | In order to improve the development efficiency and reduce the development cost of train display software,this paper designs a display dial control based on Linux Qt platform.In the Qt4 development environment,the QWidget class is inherited to combine the QLinearGradient class,QPainter class,QLabel class,etc.After coordinate transformation and rotation function,the paintEvent function is re-implemented to realize the dial control.Through the actual project verification,the control class is friendly in design,highly personalized,and enriches the traditional train display interface. |
