22 | * XMenu: MIT Project Athena, X Window system menu package | |
23 | * | |
24 | * XMenuActivate - Maps a given menu to the display and activates | |
25 | * the menu for user selection. The user is allowed to | |
26 | * specify which pane and selection will be current, | |
27 | * the X and Y location of the menu (relative to the | |
28 | * parent window) and the mouse button event mask that | |
29 | * will be used to identify a selection request. | |
30 | * | |
31 | * A menu selection is shown to be current by placing | |
32 | * a highlight box around the selection as the mouse | |
33 | * cursor enters its active region. Inactive selections | |
34 | * will not be highlighted. As the mouse cursor moved | |
35 | * from one menu pane to another menu pane the pane being | |
36 | * entered is raised and made current and the pane being | |
37 | * left is lowered. | |
38 | * | |
39 | * Anytime XMenuActivate returns, the p_num and | |
40 | * s_num are left at their last known values (i.e., | |
41 | * the last known current pane and selection indices). | |
42 | * The following are the defined return states: | |
43 | * | |
44 | * 1) If at any time an error occurs the data | |
45 | * pointer is left untouched and XM_FAILURE | |
177c0ea7 | 46 | * is returned. |
e745ede7 DL |
47 | * |
48 | * 2) When a selection request is received (i.e., | |
49 | * when the specified mouse event occurs) the | |
50 | * data pointer will be set to the data | |
51 | * associated with the particular selection | |
52 | * current at the time of the selection request | |
53 | * and XM_SUCCESS is returned. | |
54 | * | |
55 | * 3) If no selection was current at the time a | |
56 | * selection request is made the data pointer | |
57 | * will be left untouched and XM_NO_SELECT will | |
58 | * be returned. | |
59 | * | |
177c0ea7 | 60 | * 4) If the selection that was current at the time |
e745ede7 DL |
61 | * a selection request is made is not an active |
62 | * selection the data pointer will be left | |
63 | * untouched and XM_IA_SELECT will be returned. | |
64 | * | |
65 | * Since X processes events in an asynchronous manner | |
66 | * it is likely that XMenuActivate will encounter | |
67 | * a "foreign event" while it is executing. Foreign | |
68 | * events are handled in one of three ways: | |
69 | * | |
70 | * 1) The event is discarded. This is the default | |
71 | * mode and requires no action on the part of the | |
72 | * application. | |
73 | * | |
74 | * 2) The application has identified an asynchronous | |
75 | * event handler that will be called and the | |
76 | * foreign event handed off to it. Note: | |
77 | * AEQ mode disables this mode temporarily. | |
78 | * | |
79 | * 3) The application has enabled asynchronous event | |
80 | * queuing mode. In this mode all foreign events | |
ee7683eb | 81 | * will be queued up until XMenuActivate |
e745ede7 DL |
82 | * terminates; at which time they will be |
83 | * returned to the X event queue. As long as | |
84 | * AEQ mode is enabled any asynchronous event | |
85 | * handler as temporarily disabled. | |
86 | * | |
87 | * Any events encountered while taking down the menu | |
88 | * (i.e., exposure events from occluded windows) will | |
89 | * automatically be returned to the X event queue after | |
90 | * XMenuActivate has cleaned the queue of any of its own | |
91 | * events that are no longer needed. | |
