Re: [B2-devel] [PATCH] More clipboard-related fixes for Basilisk / SheepShaver

[Kevin J. (at home) <kj...@gm...>]

I am a user dependent on Sheepshaver who would also love to have the clipboard repaired. The issue is entirely about the Classic Mac system being aware that there has been an application switch. In the Classic Mac, the system would monitor that. However when the Classic Mac is running in emulation, it can't tell when there has been a switch to an application of the host system. That's where Sheepshaver, as the emulater, must assume that responsibility, and inform the Classic Mac system about the switch.

Right now, I can ensure a copy works by keeping an intermediary Classic Mac app. I mainly use Stickies for that purpose, because it strips formatting when it copies. If I want to keep the formatting, I use Word 5.1. So, from my Classic app, I copy, then go to the intermediary Classic app and paste. Then I switch to Mac X and can paste. 

To copy from Mac X, I must go to the intermediary Classic app, then switch to the intended Classic Mac target, then switch to the Mac X app and copy. Then I return to the intended Classic Mac target. I still can't paste. If I attempt to do so, it will bugger the process and I will have to start over. Instead, I must go to the intermediate Classic Mac app and paste. THEN I return for the 3rd time to the intended Classic Mac target and can now paste.

It's not quite that simple. Sometimes it will work with the first paste of the day. Sometimes it will just work for no reason I can see. But the above method is the only way to be sure it will work.

It seems like a simple solution would be to create a dummy Classic app. Then whenever Sheepshaver loses focus, it would make note of the current Classic Mac app (the 'departed'), and switch to the dummy Classic Mac app, triggering a clipboard update. Then when Sheepshaver gets focus back, it would tell Classic Mac to return to the 'departed' app, triggering another clipboard update. I don't know whether Sheepshaver would have to update the Mac X clipboard or whether than happens automatically with the change in focus.

Weirdly, the old Classic Mac application 4D has no problems with the clipboard. It must have fanatically triggered a clipboard update every time it was used, or maybe it didn't keep a private clipboard. Anyway, pretty much every other Classic Mac app must have tried to be efficient, and is consequently being a pain in the ass.

Just leave the Clipboard window in MacOS Finder open. With the Clipboard window open, not only switching to the MacOS Finder after copying in AppleWorks works to paste in TextEdit but also, after copying in TextEdit, pasting in AppleWorks works after switching from AppleWorks to the MacOS Finder and back again to AppleWorks.
