Is it possible to call system shell context menu for a file / folder from Qt app?
-
I have a path to a file system object (file / folder), and I want to all a system context (right-click) menu for it. For example, on Windows I need Windows Explorer menu.
Is it possible? -
It appears there's no wrapper for this in Qt, so on Windows one has to use WinAPI. Here's how it works:
@
bool CShellMenu::openShellContextMenuForObject(const std::wstring &path, int xPos, int yPos, void * parentWindow)
{
assert (parentWindow);
ITEMIDLIST * id = 0;
std::wstring windowsPath = path;
std::replace(windowsPath.begin(), windowsPath.end(), '/', '\');
HRESULT result = SHParseDisplayName(windowsPath.c_str(), 0, &id, 0, 0);
if (!SUCCEEDED(result) || !id)
return false;
CItemIdListReleaser idReleaser (id);IShellFolder * ifolder = 0;
LPCITEMIDLIST idChild = 0;
result = SHBindToParent(id, IID_IShellFolder, (void**)&ifolder, &idChild);
if (!SUCCEEDED(result) || !ifolder)
return false;
CComInterfaceReleaser ifolderReleaser (ifolder);IContextMenu * imenu = 0;
result = ifolder->GetUIObjectOf((HWND)parentWindow, 1, (const ITEMIDLIST )&idChild, IID_IContextMenu, 0, (void)&imenu);
if (!SUCCEEDED(result) || !ifolder)
return false;
CComInterfaceReleaser menuReleaser(imenu);HMENU hMenu = CreatePopupMenu();
if (!hMenu)
return false;
if (SUCCEEDED(imenu->QueryContextMenu(hMenu, 0, 1, 0x7FFF, CMF_NORMAL)))
{
int iCmd = TrackPopupMenuEx(hMenu, TPM_RETURNCMD, xPos, yPos, (HWND)parentWindow, NULL);
if (iCmd > 0)
{
CMINVOKECOMMANDINFOEX info = { 0 };
info.cbSize = sizeof(info);
info.fMask = CMIC_MASK_UNICODE;
info.hwnd = (HWND)parentWindow;
info.lpVerb = MAKEINTRESOURCEA(iCmd - 1);
info.lpVerbW = MAKEINTRESOURCEW(iCmd - 1);
info.nShow = SW_SHOWNORMAL;
imenu->InvokeCommand((LPCMINVOKECOMMANDINFO)&info);
}
}
DestroyMenu(hMenu);return true;
}@If I manage to do the same on Mac, I'll try to tidy up a wrapper class and opensource it.
