Hello  
j'ai un logiciel qui date un peu, les ihm sont en motif / x11, il me faut rajouter un popup menu (sur le clic droit donc). Mais voila je galère un peu :D j'ai trouvé l'exemple ci-aprés qui fonctionne mais je me demande s'il faut absolument une drawind area, moi je voudrai qu'un clic n'importe ou dans mon appli affiche le popup  :heink:  

Code :
  1. #include <Xm/RowColumn.h>
  2. #include <Xm/MainW.h>
  3. #include <Xm/DrawingA.h>
  4. #include <stdlib.h>
  6. main(argc, argv)
  7.      int argc;
  8.      char *argv[];
  9. {
  10.   XmString aide, xterm, calculatrice;
  11.   Widget toplevel, main_w, drawing_a, popup_menu;
  12.   void popup_cb(), input();
  13.   XtAppContext app;
  15.   XtSetLanguageProc (NULL, NULL, NULL);
  17.   toplevel = XtVaAppInitialize (&app, "Popup", NULL, 0, &argc, argv, NULL, NULL);
  19.   /* Create a MainWindow widget */
  20.   main_w = XtVaCreateManagedWidget ("main_w", xmMainWindowWidgetClass, toplevel,
  21.        XmNscrollingPolicy, XmAUTOMATIC, NULL);
  22.   /* Create a DrawingArea -- no actual drawing will be done. */
  23.   drawing_a = XtVaCreateManagedWidget ("drawing_a",
  24.           xmDrawingAreaWidgetClass, main_w,
  25.           XmNwidth,  500,
  26.           XmNheight, 500,
  27.           NULL);
  28.  
  29.   aide = XmStringCreateLocalized ("Aide" );
  30.   xterm = XmStringCreateLocalized ("Xterm" );
  31.   calculatrice = XmStringCreateLocalized ("Calculatrice" );
  33.   popup_menu = XmVaCreateSimplePopupMenu (drawing_a, "popup", popup_cb,
  34.       XmVaPUSHBUTTON, aide, 'a', NULL, NULL,
  35.       XmVaPUSHBUTTON, xterm, 'x', NULL, NULL,
  36.       XmVaPUSHBUTTON, calculatrice, 'c', NULL, NULL, NULL);
  37.   XmStringFree (aide); 
  38.   XmStringFree (xterm);
  39.   XmStringFree (calculatrice);
  41.   /* after popup menu is created, add callback for all input events */
  42.   XtAddCallback (drawing_a, XmNinputCallback, input, popup_menu);
  44.   XtRealizeWidget (toplevel);
  45.   XtAppMainLoop (app);
  46. }
  48. /* input() -- called in responses to events;
  49. * button-3 pops up menu.
  50. */
  51. void input(widget, client_data, call_data)
  52.      Widget widget;
  53.      XtPointer client_data;
  54.      XtPointer call_data;
  55. {
  56.   Widget popup = (Widget) client_data;
  57. /*   XmDrawingAreaCallbackStruct *cbs = (XmDrawingAreaCallbackStruct *) call_data; */
  58.   XmCallbackStruct *cbs = (XmCallbackStruct *) call_data;
  60.   if (cbs->event->xany.type != ButtonPress || cbs->event->xbutton.button != 3) return;
  62.   /* Position the menu where the event occurred */
  63.   XmMenuPosition (popup, (XButtonPressedEvent *) (cbs->event));
  64.   XtManageChild (popup);
  65. }
  67. /* popup_cb() -- invoked when the user selects an item in the popup menu */
  68. void popup_cb(menu_item, client_data, call_data)
  69.      Widget menu_item;
  70.      XtPointer client_data;
  71.      XtPointer call_data;
  72. {
  73.   int item_no = (int) client_data;
  75.   if(item_no == 0) /* Aide was selected -- display html help*/
  76.     system("galeon ../proc/aide/Aide_sosie.html" );
  77.   if(item_no == 1) /* Xterm was selected -- display an xterm*/
  78.     system("xterm" );
  79.   if(item_no == 2) /* Calculatrice was selected -- display the gcalc utility*/
  80.     system("gcalc" );
  81. }
