17 | * - Remainder of the context menu: |
5bf9955d |
18 | * |
19 | * - Event Log (this means we must implement the Event Log; not |
20 | * in pterm) |
21 | * |
22 | * - New Session and Duplicate Session (perhaps in pterm, in fact?!) |
23 | * + Duplicate Session will be fun, since we must work out |
24 | * how to pass the config data through. |
25 | * + In fact this should be easier on Unix, since fork() is |
26 | * available so we need not even exec (this also saves us |
27 | * the trouble of scrabbling around trying to find our own |
28 | * binary). Possible scenario: respond to Duplicate |
29 | * Session by forking. Parent continues as before; child |
30 | * unceremoniously frees all extant resources (backend, |
31 | * terminal, ldisc, frontend etc) and then _longjmps_ (I |
32 | * kid you not) back to a point in pt_main() which causes |
33 | * it to go back round to the point of opening a new |
34 | * terminal window and a new backend. |
35 | * + A tricky bit here is how to free everything without |
36 | * also _destroying_ things - calling GTK to free up |
37 | * existing widgets is liable to send destroy messages to |
38 | * the X server, which won't go down too well with the |
39 | * parent process. exec() is a much cleaner solution to |
40 | * this bit, but requires us to invent some ghastly IPC as |
41 | * we did in Windows PuTTY. |
42 | * + Arrgh! Also, this won't work in pterm since we'll |
43 | * already have dropped privileges by this point, so we |
44 | * can't get another pty. Sigh. Looks like exec has to be |
45 | * the way forward then :-/ |
46 | * |
47 | * - Saved Sessions submenu (not in pterm of course) |
48 | * |
49 | * - Change Settings |
50 | * + we must also implement mid-session reconfig in pterm.c. |
51 | * + note this also requires config.c and uxcfg.c to be able |
52 | * to get hold of the application name. |
53 | * |
54 | * - Copy All to Clipboard (for what that's worth) |
