Hi,

it looks like that the function

QWindowsSystemTrayIcon::showMessage

has a severe handle leak.

tnd.hBalloonIcon = qt_pixmapToWinHICON(pm);

The icon should get released after displaying the notification.

After ~10000 calls all handles are allocated and the program crashes.

Regards

Alex

 

 

 

QPixmap pm = icon.pixmap(size);
if (pm.isNull())

{ tnd.dwInfoFlags = NIIF_INFO; }

else {
if (pm.size() != size)

{ qWarning("QSystemTrayIcon::showMessage: Wrong icon size (%dx%d), please add standard one: %dx%d", pm.size().width(), pm.size().height(), size.width(), size.height()); pm = pm.scaled(size, Qt::IgnoreAspectRatio); }

tnd.hBalloonIcon = qt_pixmapToWinHICON(pm);
}
tnd.hWnd = m_hwnd;
tnd.uTimeout = msecsIn <= 0 ? UINT(10000) : UINT(msecsIn); // 10s default
tnd.uFlags = NIF_INFO | NIF_SHOWTIP;

Shell_NotifyIcon(NIM_MODIFY, &tnd);

// RELEASE the icon...
