items : a collection of menu items
Item format :
( 'Item text', 'path/to/image', command )
OR
( 'Item text', 'path/to/image', command, arg1,arg2,.... )
If you don't want to use an image, pass 0.
To create disabled item, pass 0 for the command :
( 'Item text', 'path/to/image', 0 )
so, you can easily switch between enabled or disabled :
( 'Item text', 'path/to/image', command if commandEnabled else 0 )
OR
( 'Item text', 'path/to/image', (0,command)[commandEnabled] )
To create submenu, pass a sequence of submenu items for the command.
To create disabled submenu, pass an empty sequence for the command.
To enable hotkey, insert an underscore before the character,
e.g. hotkey of 'Item te_xt' is 'x' key.
To add shortcut key text at the right side of the item, append it at the end of
the item text, separated by "more than" sign, e.g. 'Item text>Ctrl-T'.
To insert separator line, pass 0 for the whole item.
parent : where to attach the menu, defaults to aspect2d
buttonThrower : button thrower whose thrown events are blocked temporarily
when the menu is displayed. If not given, the default
button thrower is used
onDestroy : user function which will be called after the menu is fully destroyed
font : text font
baselineOffset : text's baseline Z offset
scale : text scale
itemHeight : spacing between items, defaults to 1
leftPad : blank space width before text
separatorHeight : separator line height, relative to itemHeight
underscoreThickness : underscore line thickness
BGColor, BGBorderColor, separatorColor, frameColorHover, frameColorPress,
textColorReady, textColorHover, textColorPress, textColorDisabled
are some of the menu components' color
minZ : minimum Z position to restrain menu's bottom from going offscreen (-1..1).
If it's None, it will be set a little above the screen's bottom.
