| Displaying a Context
Menu for a File
This code, when used with SHGetIDListFromPath can be used to provide the same popup menu as Explorer for a given file or folder. There is one problem however - the "Send To" menu doesn't load properly (I usually have NotePad in Send To to quickly view text, Delphi or C++ files and not having anything there can be annoying). If anyone knows a fix... |
aPopup := CreatePopUpMenu;
if aPopup
= 0 then exit;
try
OLECheck(aContextMenu.QueryContextMenu(aPopup,
0, 1, $7FFF, CMF_NORMAL));
aCmd
:= Integer(TrackPopupMenuEx(aPopup, TPM_LEFTALIGN or TPM_RETURNCMD
or
TPM_RIGHTBUTTON or TPM_HORIZONTAL or TPM_VERTICAL, Where.X, Where.Y,
Application.MainForm.Handle, nil));
if
aCmd <> 0 then
begin
Fillchar(aCmdInfo, Sizeof(aCmdInfo), 0);
with aCmdInfo do
begin
cbSize := SizeOf(TCMInvokeCommandInfo);
hwnd := Application.MainForm.Handle;
lpVerb := MakeIntResource(aCmd - 1);
nShow := SW_SHOWNORMAL;
end;
try
aContextMenu.InvokeCommand(aCmdInfo);
except
raise Exception.Create('The system menu for this file could not
be created.');
end;
end;
finally
DestroyMenu(aPopup);
end;
end;
The following is an example of using SHGetIDListFromPath and ContextMenuForFile.
procedure DisplayContextMenuForFile(FileName:
string);
var ShellFolder:
IShellFolder;
Pidl:
pItemIDList;
begin
Pidl := SHGetIDListFromPath(FileName,
ShellFolder);
if Assigned(Pidl)
then
ContextMenuForFile(ShellFolder,
Pidl);
end;
