java - Infinite Rotation Command (or button) in toolbar in Codename One -


i'd 'infinite' rotate on of commands (the refresh command) in codename one toolbar (until loading done, want stop rotation, image still has visible). can change icon start rotation? how can achieve result?

the rotating icon should not clickable when rotating, should not hard implement.

you can use toolbar api , little bit of hack. created methods below that:

private void showtitleprogress(toolbar t) {     int pos = t.getcomponentcount() - 1; //if have command on left command     //int pos = t.getcomponentcount(); //if don't have command on left command     infiniteprogress ip = new infiniteprogress();     ip.setanimation(yourprogressimage);     ip.setuiid("icon");     container contip = flowlayout.enclosecentermiddle(ip);      component.setsamewidth(t.getcomponentat(pos), contip);     component.setsameheight(t.getcomponentat(pos), contip);     t.replaceandwait(t.getcomponentat(pos), contip, null);     t.revalidate(); }  private void hidetitleprogress(toolbar t, command cmd) {     int pos = t.getcomponentcount() - 1; //if have command on left command     //int pos = t.getcomponentcount(); //if don't have command on left command     button cmdbutton = new button(cmd.geticon());     cmdbutton.setuiid("titlecommand");     cmdbutton.setcommand(cmd);     t.replaceandwait(t.getcomponentat(pos), cmdbutton, null);     t.getcomponentform().revalidate(); }

use toolbar api , form this:

private command mycommand = new command(""); form f = new form("test form"); toolbar t = new toolbar(); f.settoolbar(t);  command = new command("back") {      @override     public void actionperformed(actionevent evt) {        //do stuff     } }; back.putclientproperty("uiid", "backcommand"); f.setbackcommand(back); t.addcommandtoleftbar(back);  mycommand = new command(yourprogressimage) {      @override     public void actionperformed(actionevent evt) {         //to show progress when actions being performed          showtitleprogress(t);         //when you're done, discard progress , restore command         hidetitleprogress(t, mycommand);     } } mycommand.putclientproperty("titlecommand", true); t.addcommandtorightbar(mycommand); f.show();

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
