java - Change Icon dynamically in JTable -

-

i have jtable jlabel show given picture if person approved(or failed) in test.i use renderer:

public  class testcellrenderer extends jlabel implements tablecellrenderer {          list<student> list=null;   public testcellrenderer(list<student> l){       super();       this.list=l;        }       @override   public component gettablecellrenderercomponent(jtable table, object object,boolean isselected, boolean hasfocus, int row, int column) {             student s=list.get(row);           if(s.getpoints()>=90){                   seticon(new imageicon(getclass().getresource(okay_path)));}           else if(s.getpoints()<90){               seticon(new imageicon(getclass().getresource(error_path)));          }                                }                  sethorizontalalignment(jlabel.center);                 return this;       } }//end renderer

it works flawless until have edit student in jtable row.i open screen contents of row edition.of course, table model dont show value, jlabel show picture.but in edit frame, have box values.i tried update after choose value dont works(off course, if close main frame , open imagem showed modified, need show rows updated after close edit frame(note: other fields change in edit frame updates, less jlabel).i tried in mymodel(just relevant parts):

studenttablemodel extends abstracttablemodel{  public void setvalueat(object avalue, int rowindex, int columnindex) {   student s=students.get(rowindex);  //...many cases    case grade_point: s.setgrade((jlabel)avalue);    firetablecellupdated(rowindex, columnindex); // notify update } public void setdata(list<student> list){     this.students.clear();     for(student s:list){              student student=new student();               student.setid(c.getid());              //...other setters ,              student.setgradepointimage(setjlabel(s.getpoints()));              this.students.add(student);                 }     this.firetabledatachanged();  }//end set data public student getstudent(int rowindex){   student s=students.get(rowindex);   student student=new student()   //setters  return student; } public jlabel setjlabel(int value){         jlabel l=new jlabel();              if(value>=90)            l.seticon(new imageicon(getclass().getresource("...successpath")));              else if(value<90)            l.seticon(new imageicon(getclass().getresource("...failedpath")));          return l;   } }//end studenttablemodel

i have mainframe table(and respective rows showed), , editframe, displayed if user clicks twice in row.everything works fine picture update.oh, in editframe:

    if (arg0.getsource() == exitdialog) {            model.setdata(mylist);            model.firetabledatachanged();          dispose();//clear editframe        }//it should update after editframe closed.

it updates icon.what can update icon? best regards,

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
