如何在 Windows 中以编程方式选择弹出菜单项?

我有一个应用程序,我正在为其编写一个小向导。 它通过将鼠标移动到适当的按钮、菜单并单击它们来自动化应用程序的一小部分,以便用户可以观看。

到目前为止,它将鼠标移动到树项目并发送右键单击。 通过 TrackPopupMenu 弹出一个菜单。 接下来,我将鼠标移动到弹出菜单上的相应项目。 我不知道如何选择菜单项。

我尝试过将左键单击发送到菜单的所有者窗口,尝试将 WM_COMMAND 发送到菜单的所有者等。没有任何效果。

我想菜单本身就是一个窗口,但我不知道如何从我拥有的 HMENU 中获取它的 HWND。

关于如何在单击弹出菜单时发送消息有什么想法吗?

PS 我使用单独的线程来驱动鼠标并发布消息,因此 TrackPopupMenu 同步没有问题。

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.

我没有找到完美的方法来做到这一点,但以下方法效果很好:

//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;

右键单击树项时调用上述函数。 下面
代码在单独的线程中运行以进行单击

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);
}

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);
}

我希望您可以通过调用 SendInput。 将鼠标移到菜单所在的位置,然后单击。

您可能需要查看 WH_JOURNALPLAYBACK 挂钩。 我认为它的设计目的正是您似乎想要手动执行的操作。

I expect you could generate the necessary click messages by calling SendInput. Move the mouse over where the menu is, and then click.

You might want to take a look at the WH_JOURNALPLAYBACK hook. I think it's designed to do exactly what you seem to be trying to do manually.
