How to open a filedialog within an Eclipse Wizard -

-

i'm writing eclipseplugin, has create new project. works far, need copy external file projectfolder. intend have 'browse' button on 1 of wizardpages, opens filedialog, user can browse file , after closing dialog can use path file various actions. problem dialog window never opens. right i'm trying way (snippet wizardpage):

    public void createcontrol(composite composite) {         this.container = new composite(composite, swt.none);         gridlayout layout = new gridlayout();         this.container.setlayout(layout);         layout.numcolumns = 2;          button browsebutton = new button(this.container, swt.push);         browsebutton.settext("browse");         browsebutton.addselectionlistener(new selectionlistener() {             @override            public void widgetdefaultselected(selectionevent arg0) {                filedialog filedialog = new filedialog(datapage.this.container.getshell(), swt.open);                        filedialog.settext("jzos created file");               string path = filedialog.open();               datapage.this.setjzoscreatedname(path);          }     });

i tried several implementations, have seen in examples , tutorials nothing did work. i'm assuming problem shell give filedialog. tried open new shell within widgetdefaultselected function didn't work either. suggestions?

you should using widgetselected method of selectionlistener not widgetdefaultselected
