In a listbox showing file names, I would like a right-click to open a popup menu similar to the Windows explorer popup menu (the one with Open, Open with..., Send to, Copy, Paste, etc). How can I do that ?

How can I do that ? Thank you LM 1) create the popup, add the entries you wish 2) double-click each entry in turn: this will generate a handler for the on-click event; you can also route the clicks of all items to one event handler. Sender will tell you which menuitem triggered. 3) in the eventhandler, determine which line of the listbox was selected. The popup has properties for this: PopupComponent tells which component the popup was over (if PopupComponent IS Tlistbox then with PopupComponent AS Tlistbox do ... either refer to itemindex or to selected). The PopupPoint property indicates x and y (in screen coordinates) of the calling point. But I don't think you need those. If you do, you'll have to determine x,y offset of the listbox and the lineheight.

I don't want my popup menu to be "my" menu but THE Windows Explorer Popup File Menu, the one with the usual items (Open, Rename, Copy, Paste, Send to, etc.) and the specific items depending on file types (eg. "Extract to" for a zip file, "View" for a a bmp file, etc.) or specific installed applications. I looked in the Registry for this kind of key but I found nothing. Sorry for my mis-writing.

The latter is quite hard enough; the former should by rights be impossible - which means it may just be dead easy if you know exactly where to look.

Unfortunately, it's spread over at least three or four different mechanisms by now. The oldest, simplest one starts with a key for the extension that has a pointer to the type, and keys with menu captions and commands under the type's Shell subkey. But that's too simple for these modern times of per-user customisation, so it was modified and extended clear out of recognisable reality. And then there are the other schemes.

How can I do that ? Have you seen Virtual Shell Tools? It's free, and it might just handle everything you need. It can generate the context menu for a file or group of files. It can also display a directory full of files, along with their associated icons. http://www.mustangpeak.net/ -- Rob Back to top La Mygale Guest Posted: Thu Jan 12, 2006 5:34 pm    Post subject: Re: Windows Popup Menu Maarten Wiltink a écrit : Quote: [...] I don't want my popup menu to be "my" menu but THE Windows Explorer Popup File Menu, Do you actually want the Explorer's menu, Yes sir ! The Popup File Menu. Quote: the former should by rights be impossible - which means it may just be dead easy if you know exactly where to look. That's what I guessed... The kind of API Call or SendMessage or whatever which is documented nowhere... Looks like I'll have to type lines and lines of code and use lots ressources to reinvent the wheel. Thanks for your answer anyway. LM Back to top Hans-Peter Diettrich Guest Posted: Fri Jan 13, 2006 1:37 am    Post subject: Re: Windows Popup Menu La Mygale schrieb: Quote: That's what I guessed... The kind of API Call or SendMessage or whatever which is documented nowhere... You cannot expect that every feature of a MS program (like Explorer) is an API function. Since MS software typically is not open source, you'll have to guess how something is done, in most cases. If you want more transparency, you should choose a more appropriate platform for your development, like Linux...

You're right, but Delphi provides an example : "ShellListView" which probably uses some MS stuff (and the famous RightClick on files).
