Popup menu pops up in wrong place
-
I derived a class from CListBox. In that class I added a handler for the right mouse button. When I click the right button, the menu pops up on my desktop. I know why its doing this, because the CPoint passed to the function is relative to the whole screen, not my listbox. I cant figure out how to tell the menu to popup where my mouse is. I tried ScreenToClient() but it didnt work.
void CMyListBox::OnRButtonUp(UINT nFlags, CPoint point) { CMenu Menu; Menu.LoadMenu(IDR_POPUP_MENU); CMenu *Popup = Menu.GetSubMenu(0); ScreenToClient(&point); Popup->TrackPopupMenu(TPM_LEFTBUTTON|TPM_RIGHTBUTTON|TPM_LEFTALIGN, point.x, point.y, this, NULL); Menu.DestroyMenu(); }Anybody help? Thanks! -

Thanks!You have two problems. First, the
pointparameter is in window coords, not screen coords. Second,TrackPopupMenu()takes screen coords for the menu location. So you should callClientToScreen(&point)--Mike-- Ericahist | CP SearchBar v2.0.2 | Homepage | 1ClickPicGrabber New v2.0.1! | RightClick-Encrypt You cannot truly appreciate Dilbert unless you've read it in the original Klingon. -

Thanks!The point is given to you in client coords, and
TrackPopupMenu()expects screen coords, so useClientToScreen()to convert the point.

Thanks!Or you could just call ::GetCursorPos(&point); Which will give you the current mouse position in screen coordinates Roger Allen - Sonork 100.10016 Roger Wright: Remember to buckle up, please, and encourage your friends to do the same.
