PullDown menu provides the top (always visible) part of these menus.
It controls display of its menus, which become visible when one of the
PullDownMenus entries is pressed.
Instance variables:
menus <aCollection> the sub menus
titles <aCollection> the strings in the menu
activeMenuNumber <Number> the index of the currently active menu
showSeparatingLines <Boolean> show separating lines between my menu-strings
topMargin <Number> number of pixels at top
fgColor <Color> color to draw passive menu-titles
bgColor <Color> color to draw passive menu-titles
activeFgColor <Color> color to draw activated menu-titles
activeBgColor <Color> color to draw activated menu-titles
onLevel <Integer> level of entry-buttons when pressed
offLevel <Integer> level of entry-buttons when released
keepmenu <Boolean> if on, pulled menu stays on click,
till clicked again (motif & windows behavior)
StyleSheet values:
pullDownMenuViewBackground view background Color for the menu bar
default: menuViewBackground
pullDownMenuForegroundColor foreground drawing color for the menu bar
default: menuForegroundColor
pullDownMenuBackgroundColor background drawing color for the menu bar
default: menuBackgroundColor
pullDownMenuHilightForegroundColor active foreground drawing color for the menu bar
default: menuHilightForegroundColor
pullDownMenuHilightBackgroundColor active background drawing color for the menu bar
default: menuHilightBackgroundColor
pullDownMenuHilightLevel level (3D only) when active
default: menuHilightLevel
pullDownMenuEdgeStyle edge style (nil or #soft)
pullDownMenuKeepMenu if true, pulled menu stays open until button
is pressed again (motif behavior)
if false, menu closes on release (default)
pullDownMenuToggleKeep if true, pulled menu closes when an entry is pressed
again. Otherwise, only press outside outside of
the entry hides it.
