c++星星动画效果分解。:
主要是4个动画效果,
一个是放大缩变效果:这个前半段起效果.
一个是位移效果,这个这个效果全程进行
一个旋转效果:这个效果全程进行
最后一个缩小效果,,,后半段生效.
c++动画单个流程分解:代码太复杂,,仅仅以移动效果为例子..
int fps=24;
int millsecs=2000; //动画执行毫秒数...重要..
int time_span=1000/fps; //这个做为定时器运行时间间隔
//以下代码计算每次位移像素..
int fps_count=fps*sec/1000;
x_span=(float)(x_max-x_mini)/(float)fps_count;
//以下代码计算出本次实际位置。
x_cur=x_cur+x_span;
y_cur=y_cur+y_span;
c++的实现总结.:
///
放大缩变效果, 旋转效果,缩小效果, 位移效果分别有一个定时器控制..
代码量不少。。写了五个类。。
增加了cli接口,可以供其他程序调用.
不规则透明窗体的实现方式：
一种是设置窗体的掩码图像；
另一种是设置窗体背景透明，然后重写其绘图函数，将背景图绘制上去。
//must set falg togethoer.. 这几个参数要一起使用,贝儿走最后一个生效.
setWindowFlags( Qt::FramelessWindowHint
| Qt::WindowStaysOnTopHint |Qt::Tool );
this->setAttribute(Qt::WA_TranslucentBackground);//设置背景透明
menuBar()->hide(); //隐藏菜单栏.
ui->mainToolBar->hide(); //隐藏工具栏.
ui->statusBar->hide(); //隐藏缩放手柄
QPixmap1.load("C:\\favstar\\star.png");//加载图像
void IrregularForm2::paintEvent(QPaintEvent * event)
{
QPainter painter(this);
//draw in the top(0,0) in the windows
QPixmap pix2=QPixmap1.scaled(this->size(), Qt::IgnoreAspectRatio, Qt::SmoothTransformation);
painter.drawPixmap(0, 0, pix2);//绘制图像
}
