java - How to close current JFrame? -

-

i have read similar topics did find answer there.

i created jframe close button. after click want close current window. try setdefaultcloseoperation(jframe.hide_on_close), or setvisible(false).

public class windows {  jframe frame;  jframe frame1;   public windows(){  }     public jframe getcreateframe(){    frame1 = new jframe("create user");   frame1.setsize(500,500);   frame1.setvisible(true);   frame1.getcontentpane().add(new panels().getwelcomtxtlabelpanel1(), borderlayout.north);   frame1.getcontentpane().add(new panels().getcreateuser(), borderlayout.south);    frame1.getcontentpane().add(new panels().getuserlabel(), borderlayout.west);   frame1.getcontentpane().add(new panels().getuserfield(), borderlayout.center);   return frame1;      }   }

here button.

public jbutton getcancelbutton(){   cancel = new jbutton("cancel");  cancel.addactionlistener(new actionlistener() {   public void actionperformed(actionevent e){           new windows().getcreateframe().setdefaultcloseoperation(jframe.hide_on_close);                }          }); return cancel;      }

the problem following action (and not this):

cancel.addactionlistener(new actionlistener() {    public void actionperformed(actionevent e){       new windows().getcreateframe().setdefaultcloseoperation(jframe.hide_on_close);    } });

here create new windows object , call getcreateframe() creates new jframe , call setdefaultcloseoperation() on it.

so you work different windows / jframe instances.

instead should create jframe in constructor of windows , call setdefaultcloseoperation(jframe.hide_on_close) of jframe in constructor well.

afterwards can use setvisible(false) in action - jframe , not new created one.

btw. getcancelbutton() should not create new button every time called.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
