A key held from the menu (Hold Ctrl, Alt or Windows) is the same key as
the keyboard's left Ctrl, Alt or Windows key. Pressing and releasing
that key on the screen let the VM's key go, while the menu still showed
it held. And when the key went down outside the screen (in the
Clipboard dialog) and came up on it, noVNC sent no release, as it had
not seen the key go down.
The release of that key where noVNC takes keys (the screen, the touch
keyboard) now lets a held key go itself, and clears the menu's mark. A
release elsewhere reaches no VM and changes nothing.
The VM page offered a lite and a full VNC console. Lite lacked a clipboard,
display settings and a way to reconnect; full put noVNC's own side bar under
the panel's bar, with a Fullscreen item that called a function noVNC does
not have, status messages hidden behind the bar, saved noVNC settings that
overrode the Access tab's, connection settings that cannot apply, and a
Connect button that reused the page's two-minute token and failed.
console-vnc.html and static/js/console_vnc.js replace both, on noVNC's RFB
with Bootstrap controls, and keep what the full view did:
- Status in the bar (Connecting, Connected, Disconnected, Connection lost,
Could not connect, Authentication failed with the server's reason on
hover); Disconnect, then Reconnect, which loads the page again for a new
token.
- The VNC password in a dialog (with a username when the server asks for
one), not a browser prompt; without passwordless console it is not in
the page.
- Send key(s) gains Hold Ctrl / Alt / Windows (noVNC's extra keys).
- Clipboard: what the VM copies, sending text to the VM's clipboard, and
typing it key by key (new: works in firmware, installers and login
prompts; Shift for the characters a US keyboard shifts, 25 ms a key as
firmware drops faster keys, verified in a UEFI shell).
- View: scaling (none, fit, resize the VM's screen), clip, drag a clipped
screen, view only, dot cursor, quality, compression; it starts as
Settings > Console says (a touch screen starts fitted).
- A Keyboard item on touch devices (noVNC's on-screen keyboard input,
key events and Android's text-only input), Fullscreen with keyboard
lock, the bell.
Dropped with the full view: noVNC's websocket host/port/path, repeater ID
and log level (the panel fixes them), automatic reconnect (the token is
single use in time), XVP power buttons (QEMU has no XVP) and shared-mode off.
The bar is compact (about 45 px in the 850x600 window). The Access tab has
one Console button instead of the Lite/Full split and four switches, and
it and the VM list open one window per VM (opening it again reloads it).
The lite and the full console page each carried the same 150 lines that
send key combinations (Ctrl+Alt+Del, Ctrl+Alt+F1..F12, Alt+Tab, ...). They
now import static/js/console_keys.js, which binds the menu to the page's
RFB connection.
