MUI_Menustrip

Menustrip.mui

Super class

Family.mui

Background

Menustrip class is the base class for MUI's object oriented menus. Its children are objects of Menu class, each of them describes exactly one menu.

A Menustrip object doesn't feature many options itself, but as a subclass of Family class, it simply acts as father for multiple Menu objects.

The Menustrip object is usually specified as a child of either Application class or Window class with the attributes MUIA_Application_Menustrip or MUIA_Window_Menustrip.

MUIA_Menustrip_CaseSensitive

NAME

MUIA_Menustrip_CaseSensitive -- V20 [I.G], BOOL, 0x8042d718

FUNCTION

Set this attribute to TRUE in case the menu strip is using items with the same upper and lower case shortcuts, i.e. 'a' and 'A'. Otherwise MUI will not be able to distinguish between the two and will most probably find the upper case shortcut only and trigger the corresponding action.

Defaults to FALSE.

MUIA_Menustrip_Enabled

NAME

MUIA_Menustrip_Enabled -- V8 [ISG], BOOL, 0x8042815b

FUNCTION

Enable or disable the complete menu strip.

MUIM_Menustrip_ExitChange

NAME

MUIM_Menustrip_ExitChange -- V20, 0x8042ce4d

SYNOPSIS

DoMethod(obj, MUIM_Menustrip_ExitChange);

FUNCTION

Terminates MUIM_Menustrip_InitChange state.

MUIM_Menustrip_InitChange

NAME

MUIM_Menustrip_InitChange -- V20, 0x8042dcd9

SYNOPSIS

DoMethod(obj, MUIM_Menustrip_InitChange);

FUNCTION

Prepares a menustrip for dynamic adding/removing of items. MUI 3 offers the possibility to dynamically add/remove items from menustrips, even when the window that contains these items is currently open. To be able to do this, you must first put the menustrip into a special "exchange" state by using this method. Then, you can add/remove item at will. When you're done, use MUIM_Menustrip_ExitChange to make MUI relayout the menustrip.

EXAMPLE

/* remove two items, add another one */
if(DoMethod(strip, MUIM_Menustrip_InitChange))
{
  DoMethod(strip, OM_REMMEMBER, someitem);
  DoMethod(strip, OM_REMMEMBER, someitem2);

  DoMethod(strip, OM_ADDMEMBER, somenewitem);

  DoMethod(strip, MUIM_Menustrip_ExitChange);
}
