更新一下程序（嵌套窗口鼠标滚轮事件无效解决）
h头文件
//加载Unity3D窗口
void loadWindowUnity3DExe(std::function f);
cpp文件
/**
* 加载Unity3D窗口
* @brief loadWindowUnity3DExe
* @return
*/
void loadWindowUnity3DExe(std::function f)
{
QString cmd = QDir::currentPath()+"/model0714/motioncapture.exe";
QFileInfo file(cmd);
if(file.exists()==false){
f(0);
return;
}
//启动exe程序
QProcess myprocess;
myprocess.startDetached(cmd,QStringList());
WId wid = 0;
do
{
QEventLoop loop;
QTimer::singleShot(1, &loop, SLOT(quit()));
loop.exec();
wid = (WId)FindWindow(L"UnityWndClass",L"motioncapture");
}while(wid == 0);
f(wid);
}
mainwindow.cpp文件
//加载Unity3D
loadWindowUnity3DExe([=](WId wid){
//代表文件不存在或者没找到wid
if(wid == 0){
QMessageBox::warning(this,"提示",messagelist[4]);
}else {
QWindow *m_window= QWindow::fromWinId(wid);
m_window->setFlags(m_window->flags() | Qt::CustomizeWindowHint | Qt::WindowTitleHint);
QWidget *unityWidget = QWidget::createWindowContainer(m_window,ui->centralwidget);
//unityWidget->setAttribute(Qt::WA_QuitOnClose);
setCentralWidget(unityWidget);
}
});
以下是最新的内容，嵌套的窗体支持鼠标事件，具体如下：
首先是新建mainwindow, 自定义主窗口widget嵌套窗体后，不确定鼠标事件有效。
通过QProcess开启嵌套窗口并添加
QProcess *myprocess = new QProcess;
QString cmd = QDir::currentPath()+"/model0714/motioncapture.exe";
QFileInfo file(cmd);
if(file.exists()){
QStringList arguments;
arguments<<"-style"<<"fusion";
myprocess->setWorkingDirectory(QDir::currentPath()+"/model0714");
myprocess->setProcessChannelMode(QProcess::MergedChannels);
myprocess->start(cmd, arguments);
WId wid = 0;
do
{
QEventLoop loop;
QTimer::singleShot(1, &loop, SLOT(quit()));
loop.exec();
wid = (WId)FindWindow(L"UnityWndClass",L"motioncapture");
}while(wid == 0);
QWindow *m_window= QWindow::fromWinId(wid);
m_window->setFlags(m_window->flags() | Qt::CustomizeWindowHint | Qt::WindowTitleHint | Qt::FramelessWindowHint);
m_window->requestActivate();
QWidget *unityWidget = QWidget::createWindowContainer(m_window,leftSplitter);
unityWidget->setFocusPolicy(Qt::StrongFocus);
//鼠标事件有效代码
AttachThreadInput(GetWindowThreadProcessId(::GetForegroundWindow(),NULL), GetCurrentThreadId(),TRUE);
SetForegroundWindow(HWND(wid));
SetFocus(HWND(wid));
AttachThreadInput(GetWindowThreadProcessId(::GetForegroundWindow(),NULL), GetCurrentThreadId(),FALSE);
}
