7 |

|
8 |
|
|
* is supplemented by platform-specific files. The geometry calculation
|
9 |
|
|
* and drawing code for menus is in the file tkMenuDraw.c

|
|
* Notes on implementation of menus:
|
22 |
|
|
*
|
23 |
|
|
* Menus can be used in three ways:
|
24 |
|
|
* - as a popup menu, either as part of a menubutton or standalone.
|
25 |
|
|
* - as a menubar. The menu's cascade items are arranged according to
|
26 |
|
|
* the specific platform to provide the user access to the menus at all
|
27 |
|
|
* times
|
28 |
|
|
* - as a tearoff palette. This is a window with the menu's items in it.
|
29 |
|
|
*
|
30 |
|
|
* The goal is to provide the Tk developer with a way to use a common
|
31 |
|
|
* set of menus for all of these tasks.
|
32 |
|
|
*
|
33 |
|
|
* In order to make the bindings for cascade menus work properly under Unix,
|
34 |
|
|
* the cascade menus' pathnames must be proper children of the menu that
|
35 |
|
|
* they are cascade from. So if there is a menu .m, and it has two
|
36 |
|
|
* cascades labelled "File" and "Edit", the cascade menus might have
|
37 |
|
|
* the pathnames .m.file and .m.edit. Another constraint is that the menus
|
38 |
|
|
* used for menubars must be children of the toplevel widget that they
|
39 |
|
|
* are attached to. And on the Macintosh, the platform specific menu handle
|
40 |
|
|
* for cascades attached to a menu bar must have a title that matches the
|
41 |
|
|
* label for the cascade menu.
|
42 |
|
|
*
|
43 |
|
|
* To handle all of the constraints, Tk menubars and tearoff menus are
|
44 |
|
|
* implemented using menu clones. Menu clones are full menus in their own
|
45 |
|
|
* right; they have a Tk window and pathname associated with them; they have
|
46 |
|
|
* a TkMenu structure and array of entries. However, they are linked with the
|
47 |
|
|
* original menu that they were cloned from. The reflect the attributes of
|
48 |
|
|
* the original, or "master", menu. So if an item is added to a menu, and
|
49 |
|
|
* that menu has clones, then the item must be added to all of its clones
|
50 |
|
|
* also. Menus are cloned when a menu is torn-off or when a menu is assigned
|
51 |
|
|
* as a menubar using the "-menu" option of the toplevel's pathname configure
|
52 |
|
|
* subcommand. When a clone is destroyed, only the clone is destroyed, but
|
53 |
|
|
* when the master menu is destroyed, all clones are also destroyed. This
|
54 |
|
|
* allows the developer to just deal with one set of menus when creating
|
55 |
|
|
* and destroying.
|
56 |
|
|
*
|
57 |
|
|
* Clones are rather tricky when a menu with cascade entries is cloned (such
|
58 |
|
|
* as a menubar). Not only does the menu have to be cloned, but each cascade
|
59 |
|
|
* entry's corresponding menu must also be cloned. This maintains the pathname
|
60 |
|
|
* parent-child hierarchy necessary for menubars and toplevels to work.
|
61 |
|
|
* This leads to several special cases:
|
62 |
|
|
*
|
63 |
|
|
* 1. When a new menu is created, and it is pointed to by cascade entries in
|
64 |
|
|
* cloned menus, the new menu has to be cloned to parallel the cascade
|
65 |
|
|
* structure.
|
66 |
|
|
* 2. When a cascade item is added to a menu that has been cloned, and the
|
67 |
|
|
* menu that the cascade item points to exists, that menu has to be cloned.
|
68 |
|
|
* 3. When the menu that a cascade entry points to is changed, the old
|
69 |
|
|
* cloned cascade menu has to be discarded, and the new one has to be cloned.

563 |
|
|
* a menubar. For instance, say you have a menu .m1 with a cascade entry
|
564 |
|
|
* for .m2, where .m2 does not exist yet. You then put .m1 into a menubar.
|
565 |
|
|
* This creates a menubar instance for .m1, but since .m2 is not there,
|
566 |
|
|
* nothing else happens. When we go to create .m2, we hook it up properly
|
567 |
|
|
* with .m1. However, we now need to clone .m2 and assign the clone of .m2
|
568 |
|
