Question

I have an app that I’m writing a little wizard for. It automated a small part of the app by moving the mouse to appropriate buttons, menus and clicking them so the user can watch.

So far it moves the mouse to a tree item and sends a right-click. That pops up a menu via TrackPopupMenu. Next I move the mouse to the appropriate item on the popup menu. What I can’t figure out is how to select the menu item.

I’ve tried sending left-clicks to the menu’s owner window, tried sending WM_COMMAND to the menu’s owner, etc. Nothing works.

I suppose the menu is a window in and of itself, but I don’t know how to get the HWND for it from the HMENU that I have.

Any thoughts on how to PostMessage a click to the popup menu?

PS I’m using a separate thread to drive the mouse and post messages, so no problems with TrackPopupMenu being synchronous.

Answer 1

I didn’t find a prefect way to do it, but the following works pretty well:

//in my case, the menu is a popup from a tree control created with: CMenu menu; menu.CreatePopupMenu(); //add stuff to the menu... pTreeCtrl->SetMenu(&menu); m_hMenu = menu.GetSafeHmenu(); CPoint  pt; GetCursorPos(&pt); menu.TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON, pt.x, pt.y, _pTreeCtrl); menu.Detach(); m_hMenu = NULL; 

The above function was called on a right-click of the tree item. The below code gets run in a separate thread to do the click

CRect rc; GetMenuItemRect(pTreeCtrl->GetSafeHwnd(), m_hMenu, targetMenuItemIndex, &rc); if(FALSE == rc.IsRectEmpty()) {    CPoint target = rc.CenterPoint();    //this closes the menu   ::PostMessage(pTreeCtrl->GetSafeHwnd(), WM_CANCELMODE, 0, 0);   DestroyMenu(m_hMenu);   m_hMenu = NULL;   //now simulate the menu click   ::PostMessage(pTreeCtrl->GetSafeHwnd(), WM_COMMAND, targetMenuItemID, 0); }
