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()");
