Hello,

I have a toolbar which uses the TBSTYLE_DROPDOWN style. That is, when I
click
on the toolbar buttons, I get a popup menu, as shown in the MSDN toolbar
examples.

I was "wondering" if the style TBSTYLE_REGISTERDROP, is so that one can
have
the "popup menu display" as the mouse is (hovering) over the toolbar buttons
like in the standard system menu(window menu)?

If this is the case, I have tried implementing the TBN_GETOBJECT, but can't
seem to get
it working. Has anyone ever used this feature. If so, how would one handle
the notification
message.

http://msdn.microsoft.com/en-us/library/bb787272(VS.85).aspx


"Below" is the code from MSDN that handles the popup menu for the toolbar
button click.
which uses TBN_DROPDOWN.
But as stated above I am "assuming" that the TBN_GETOBJECT is for menu
display
on mouse hover, but I might be wrong?


/////////////////////////////////////////////////////////////////////

BOOL DoNotify(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
#define lpnm ((LPNMHDR)lParam)
#define lpnmTB ((LPNMTOOLBAR)lParam)

switch(lpnm->code)
{
case TBN_DROPDOWN:
{
// Get the coordinates of the button.
RECT rc;
SendMessage(lpnmTB->hdr.hwndFrom, TB_GETRECT,
(WPARAM)lpnmTB->iItem, (LPARAM)&rc);

// Convert to screen coordinates.
MapWindowPoints(lpnmTB->hdr.hwndFrom,
HWND_DESKTOP, (LPPOINT)&rc, 2);

// Get the menu.
HMENU hMenuLoaded = LoadMenu(g_hinst, MAKEINTRESOURCE(IDR_POPUP));

// Get the submenu for the first menu item.
HMENU hPopupMenu = GetSubMenu(hMenuLoaded, 0);

// Set up the popup menu.
// Set rcExclude equal to the button rectangle so that if the
toolbar
// is too close to the bottom of the screen, the menu will appear
above
// the button rather than below it.
TPMPARAMS tpm;
tpm.cbSize = sizeof(TPMPARAMS);
tpm.rcExclude = rc;

// Show the menu and wait for input.
// If the user selects an item, its WM_COMMAND is sent.
TrackPopupMenuEx(hPopupMenu,
TPM_LEFTALIGN | TPM_LEFTBUTTON | TPM_VERTICAL,
rc.left, rc.bottom, g_hwndMain, &tpm);

DestroyMenu(hMenuLoaded); return (FALSE);
}
}
return FALSE;
}



Thanks.

You are. It's for drag'n'drop.
