Re: [GITGRUB] New menu interface (implementation)

[Bean]

Hi,

Update:

Add mapkey section. For example:

mapkey {
  f5 = ctrl-x
}

maps f5 key to ctrl-x, this is important for platforms like EFI as
ctrl-x can't be input.

key name should be lowercase, it can be single character, f1 to f10,
ctrl-a to ctrl-z, left, right, up, down, home, end, delete, page_up,
page_down, esc, tab, backspace and space.

Add onkey section, which allow you to assign a function when a key is
pressed. For example ,this is the onkey section for the demo:

onkey {
  c = "menu_popup term_window"
  e = "menu_popup edit_window edit.text=command"
  f7 = "menu_popup layout_test"
  f8 = menu_toggle_mode
  f9 = halt
  f10 = reboot
}

c open a terminal window, e open a edit box to edit the current
command, use ctrl-x to save it. f7 runs the layout demo test, f8
toggle between text and graphic mode, f9 shutdown, f10 reboot.

Data binding for popup windows, for example, in the above example,

menu_popup edit_window edit.text=command

property text in the edit widget in the popup dialog binds to the
command property of current node, this is used to implement the edit
function.

Add two property attach_hcenter and attach_vcenter for layout manager.
The top widget of popup window must use absolute position, as widget
are already placed in screen and can't be moved without refresh. But
it's not easy to put the widget in the middle of screen using
attach_left/right/top/bottom, the new property attach_hcenter and
attach_vcenter defines the offset from the center of screen.

Support TAB completion for term widget.

Misc optimization for graphic updates, now it should run quite smooth.
