java - Using SWT DateSpinner with RAP does not dispose calendar widget on focus lost -

i working on project need use swt datespinner on rap application webpage. brought entire datespinner api project , have made changes accommodate in application. trying dispose calendar widget when user clicks anywhere on page outside bounds of calendar dropdown.

to accomplish tried adding focus listener widget , actual date spinner onfocuslost() method never executed whenever datespinner or calendar composite lose focus. tried add mouse event listener try dispose widget if mouse down event occurs outside calendar composite bounds doesn't executed either. showcalendar() method shown:

private void showcalendar() {     if (calendardropdown != null && !calendardropdown.isdisposed())     {         calendardropdown.dispose();     }      calendardropdown = new dropdown(this);     calendardropdown.setusingrelativecontrolwidth(false);     composite composite = calendardropdown.getdropdown();     composite.setlayout(new filllayout());      composite.setdata(calendartoggle);      calendar c = calendar.getinstance();     date date = this.getdate();      // current date in control     if (date != null)     {         c.settime(this.getdate());     }      calendarcomposite calendarwidget = new calendarcomposite(composite, c);     calendarwidget.setnoneenabled(this.allownulldate);     calendarwidget.setminimumdate(datetocalendar(getminimum()));     calendarwidget.setmaximumdate(datetocalendar(getmaximum()));      // background match calendar     composite.setbackground(calendarwidget.getbackground());     calendardropdown.show(true, composite.computesize(swt.default, swt.default));      text.addfocuslistener(new focuslistener()     {          @override         public void focuslost(focusevent event)         {               dispose();         }          @override         public void focusgained(focusevent event)         {             // todo auto-generated method stub          }     });      calendarwidget.addmaincalendarlistener(new calendarlisteneradapter()     {         @override         public void datechanged(calendar date)         {             dosetdate(date != null ? date.gettime() : null, false, true);         }          @override         public void popupclosed()         {             calendardropdown.dispose();         }     });          } 

and show method of dropdown

 if ((autohide && !dropdownshell.isvisible())){                     dropdownshell.addmouselistener(new mouselistener()         {             @override             public void mouseup(mouseevent e)             {                 // todo auto-generated method stub              }              @override             public void mousedown(mouseevent e)             {                 if (!isinside(e.x, e.y, dropdownshell.getdisplay().getbounds()))                 {                     dispose();                 }             }              @override             public void mousedoubleclick(mouseevent e)             {                 // todo auto-generated method stub              }         }); 

please let me know can make calendarwidget dispose on losing focus.

i think if widget focus in shell focused widget (your text), may not focuslost event because each shell can have it's own focused widget. happens shell text in gets deactivated, can notified using shelllistener.
