[WebPositive] select file on Open target folder

[diver]

It would have been handy if clicking Open target folder (from a downloaded item pop-up menu) selected the file in question in the opened Tracker window.

This needs some cooperation from Tracker, I think. Are there examples of doing this somewhere?

You could have a look at what happens when you click on a target link from the "Get information" window of a symbolic link, and see if that functionality is directly exported via scripting.

Besides that, ShowImage, and Mail both set the currently selected file to the file they currently show.

Actually this is already implemented in Web+, but doesn't always work. There are several problems.

• The Tracker window is open through BRoster->Launch. There is no way to know when this finishes and the window is ready to receive the selection message
• There is no direct way to find the window matching a path. Web+ currently finds the window from its title, which means the message can get to the wrong window if two open folders have the same name. It will also only select the file in one window, if there are multiple windows pointing to the same folder (either on different workspaces or because of single-window mode)

Tracker scripting support needs to be extended (there even are TODO left by Be engineers) so we can do this more reliably:

• Send an EXECUTE message to Tracker with the ref to a folder, and get back a messenger to the opened (or raised) window
• Use the received messenger to set the selection on that window.

I think that's not entirely correct. What you should do is to add "nodeRefToSelect" to the B_REFS_RECEIVED you send to Tracker for the parent folder, see ​http://cgit.haiku-os.org/haiku/tree/src/kits/tracker/Tracker.cpp#n921.
