QT实现类似qq一样的滑动窗口

这次实现了滑动窗口了.

刚开始想的用定时器,每隔一段时间往外滑一点,但是发现有些莫名其妙解决不了的问题,貌似与定时器本身的机制有关,无奈只得放弃.选择用windows自带的Sleep函数,也是每隔一段时间repaint一下,这次实现了.

然后设定一个状态值,鼠标每次点击,改变其状态,根据这个判断鼠标的滑动时间是否起作用.

代码:

#include <windows.h>

#include <QMouseEvent>

#include <QMessageBox>

FloatingWindow::FloatingWindow(QWidget *parent, Qt::WFlags flags)

: QMainWindow(parent, flags)

{

ui.setupUi(this);

ui.pushButton->setFlat(true);

ui.pushButton->setStyleSheet("background-image:url(./pic/2smallsetdown.jpg)");

ui.widget->setGeometry(-ui.widget->width(),ui.widget->y(),ui.widget->width(),ui.widget->height());

//ui.widget->setFeatures(QDockWidget::NoDockWidgetFeatures);

atout=false;

status=true;

this->setMouseTracking(true);

//ui.widget->setMouseTracking(true);

ui.centralWidget->setMouseTracking(true);

ui.axWidget->setMouseTracking(true);

//添加flash

connect(ui.axWidget,SIGNAL(FSCommand(QString,QString)),this,SLOT(flashAction(QString,QString)));

ui.axWidget->dynamicCall("LoadMovie(long,string)",0,"E://MLCN//topo_show.swf");

ui.axWidget->dynamicCall("Play()");

}
