因自身開發的程式將TImage 設為有觸控的元件,並撰寫程式碼處理,向右向左的功能,但因有特別的需求,可能在這個TImage 
的上方會開另一隻程式撥放影片,但因是隻獨力的程式,所以觸控都沒有反應是正常的,所以想了一個解決的方式,透過HOOK SetWindowsHookEx ,WH_MOUSE_LL
然後將事件寫入TMouseGestureEngine , Notification 但看起來沒有用,請問這需求要如何處理,另外不知道 TMouseGestureEngine 是要如何應用,找不到
這方面的應用,所以我使用了這種方式,大至的問題是全域的觸控反應要如何達成
LRESULT CALLBACK TPlayFullScreenDialog::LowLevelMouseProc(int nCode, WPARAM wParam, LPARAM lParam)
{
if( nCode == HC_ACTION )
{
TPoint p;
p = PlayFullScreenDialog->FullScreenPlayImage->ScreenToClient(Mouse->CursorPos);
TMessage msg;
msg.Msg = wParam;
msg.WParam = Mouse->CursorPos.x;
msg.LParam = Mouse->CursorPos.y;
PlayFullScreenDialog->m_MouseGestureEngine->Notification(msg);
switch (wParam)
{
case WM_LBUTTONDOWN:
// 按下滑鼠左鍵
if (MainForm->m_MediaBookPlay && MainForm->m_MediaBookPlay->IsRunning())
{
MainForm->m_MediaBookPlay->OnExternalMouseDown(mbLeft, p.X, p.Y);
MainForm->m_MediaBookPlay->SetMoveTimer();
PlayFullScreenDialog->m_MouseGestureEngine->Notification(msg);
}
break;
case WM_LBUTTONUP:
// 放開滑鼠左鍵
if (MainForm->m_MediaBookPlay && MainForm->m_MediaBookPlay->IsRunning())
{
MainForm->m_MediaBookPlay->SetMoveTimer();
PlayFullScreenDialog->m_MouseGestureEngine->Notification(msg);
}
break;
case WM_MOUSEMOVE:
{
// 滑鼠移動中
g_OldX = p.X;
g_OldY = p.Y;
if (g_LastBTDownX != p.X || g_LastBTDownY != p.Y)
{
if (MainForm->m_MediaBookPlay && MainForm->m_MediaBookPlay->IsRunning())
{
MainForm->m_MediaBookPlay->SetMoveTimer();
}
g_LastBTDownX = p.X;
g_LastBTDownY = p.Y;
}
PlayFullScreenDialog->m_MouseGestureEngine->Notification(msg);
break;
}
case WM_MOUSEWHEEL:
// 捲動滾輪
break;
case WM_RBUTTONDOWN:
// 按下滑鼠右鍵"
if (MainForm->m_MediaBookPlay && MainForm->m_MediaBookPlay->IsRunning())
{
MainForm->m_MediaBookPlay->SetMoveTimer();
}
break;
case WM_RBUTTONUP:
// 放開滑鼠右鍵
if (MainForm->m_MediaBookPlay && MainForm->m_MediaBookPlay->IsRunning())
{
MainForm->m_MediaBookPlay->SetMoveTimer();
}
break;
}
}
return CallNextHookEx(g_hhook, nCode, wParam, lParam);
}
