Coding: I would like to be able to "Leave Out" or "Put Away" icons programmatically

[nyteschayde]

Does anybody know much about the mechanism behind leaving and icon on the workbench and putting one away? I'd like to programmatically do this technique from within an application but I don't know where to look for APIs or information about the mechanism behind this functionality.

Also, is it possible to add an icon that doesn't represent something on the filesystem. It seems like it should be possible given things like Iconify seem to work similarly. Any info on this would also be appreciated.

im not a programmer but its saved in the .backdrop file saved in root of the partition iirc. So you just need to edit that file.

I can't remember 100% off-hand (I'll check when I get home) but I think from 3.5 up you can carry this function out using ARexx commands. Might be the simplest way to do it - issue an "RX ADDRESS 'WORKBENCH' " from your application.

This is called an "App Icon" and it's how YAM puts an icon on the desktop showing the status of your mailbox, PPaint lets you load files by dragging and dropping onto its app icon, and so on. I'm sure there's something in the SDK documents about setting up an app icon. It basically triggers an event which your application then acts upon as you desire.

Thanks. Let me know what you can. It would be nice to do this without having another dependency like ARexx but worse come to worst I can do that. I modified the .backdrop file but changes didn't take effect so I assume there is something I need to do to make the system recognize the changes. Reset WB didn't do it (what is that good for anyway?!)

Icons can be added to Workbench with AddAppIcon() of workbench.library.

Reset WB is a mysterious and powerful function.

It's possible to send an ARexx command to a program's ARexx port without "using" ARexx. The port is a standard Amiga Port and the message contents are a standard string (including numbers). The program may open ARexx itself to parse the command that is sent though.

Here is a guide with the Workbench Arexx interface (AmigaOS 3.5+)...

This guide should already be installed if you are using the unofficial AmigaOS 3.9 BoingBag 3 and up. If installed, you can use the help key at any time from Workbench to bring it up. You can also use the help key while in the menu to bring up help for a particular menu item. It's not very thorough with the help but the Workbench ARexx documentation is quite good. It looks like the icons you want to put away or leave out would have to be selected with the "ICON" command (or let the user do it) then the "MENU INVOKE ICONS.LEAVOUT" or "MENU INVOKE ICONS.PUTAWAY" command used to do the work. Using the "WORKBENCH" ARexx host is a lot better and more reliable than hacking it even if you send the command directly to this port without opening ARexx.

Wow, that's great info. Perhaps I have been too biased with my slant on doing without dependencies. I'll look into it. The problem is that I am writing some CLI commands for use in very early startup (before Workbench is loaded) but would like to work even after it's come up.

Thanks for all that information. I'll see what I can drum up if my install of CubicIDE ever finishes.

Well, you cannot tell Workbench to leave out icons when there is no Workbench around to listen. Sounds to me like you want to edit the :.backdrop files, these will be read by Workbench when it is launched.

And it's mystery is exceded only by it's power.

[nyteschayde]

So what you're saying is that what it does is undocumented and has no immediately visible effect. Mysterious and powerful indeed.

Nah, it's in my WB guide . ResetWB closes and reopens all Workbench windows. It's even more useful than "Redraw all" .
