Clipboard

Copy

"Copy" for now will do the following:

  • Pre-allocate enough memory for conceivable Apple II bitmaps (640x216 should do it)

Call the Display Engine Copy routine

This routine (depending on display engine) will:

  • Copy the screen buffer to the temporary memory after it.
  • return the bitmap dimensions

"Copy" will then populate the bmp header for use when / if the clipboard callback routine is called.

Paste

Paste is handled by the keyboard module. When a paste is done, copy the pasted string into a buffer.

II / IIe: each time $C000 is read, if the strobe is clear (bit 7 = 0), inject the next character from the buffer. If the strobe is set, the guest has not processed the current keystroke. Shift+Insert, Edit → Paste Text, and debug-protocol PASTE_TEXT fill this buffer.

IIgs (KeyGloo / ADB): meter from the KeyGloo frame_handler (once per frame). If paste text remains and the $C000 latch strobe is clear, inject one ASCII character via store_key_to_buffer() ('\n' becomes '\r'). Reset and keyboard flush abort the paste. Shift+Insert, Edit → Paste Text, and debug-protocol PASTE_TEXT all fill this buffer.

Implemented!
