1. [solved!] how expand swt browser open more 1 tab ?
   • i used tabfolder more tabs.
2. it possible catch url after click on button , open in new swt browser tab ?

swt uses 1 of browsers available on operating system , embeds main "view" of browser (the bit displays html) in application. mean, however, doesn't come fancy stuff tabs.

as discovered yourself, can around using tabfolder.

the question is: how know when tab should opened. code (adopted snippet270) should this:

public static void main(string[] args) {     display display = new display();     shell shell = new shell(display);     shell.settext("main window");     shell.setlayout(new filllayout());     final browser browser;     try     {         browser = new browser(shell, swt.none);     }     catch (swterror e)     {         system.out.println("could not instantiate browser: " + e.getmessage());         display.dispose();         return;     }     initialize(display, browser);     shell.open();     browser.seturl("http://www.w3schools.com/html/tryit.asp?filename=tryhtml_links_target");     while (!shell.isdisposed())     {         if (!display.readanddispatch())             display.sleep();     }     display.dispose(); }  /* register windowevent listeners */ static void initialize(final display display, browser browser) {     browser.addopenwindowlistener(e ->     {         shell shell = new shell(display);         shell.settext("new window");         shell.setlayout(new filllayout());         browser browser1 = new browser(shell, swt.none);         initialize(display, browser1);         e.browser = browser1;     });     browser.addvisibilitywindowlistener(new visibilitywindowlistener()     {         @override         public void hide(windowevent e)         {             browser browser = (browser) e.widget;             shell shell = browser.getshell();             shell.setvisible(false);         }          @override         public void show(windowevent e)         {             browser browser = (browser) e.widget;             final shell shell = browser.getshell();             if (e.location != null) shell.setlocation(e.location);             if (e.size != null)             {                 point size = e.size;                 shell.setsize(shell.computesize(size.x, size.y));             }             shell.open();         }     });     browser.addclosewindowlistener(e ->     {         browser browser1 = (browser) e.widget;         shell shell = browser1.getshell();         shell.close();     }); } 

this open link in new shell new browser. can change this, creates new tab , adds new browser new tab.

edit

here's working example using tabfolder:

public static void main(string[] args) {     display display = new display();     shell shell = new shell(display);     shell.settext("main window");     shell.setlayout(new filllayout());      tabfolder tabfolder = new tabfolder(shell, swt.border);      addnewbrowser(tabfolder, "<a href='http://www.google.co.uk' target='_blank'>click here!</a>");      shell.open();     while (!shell.isdisposed())     {         if (!display.readanddispatch())             display.sleep();     }     display.dispose(); }  private static browser addnewbrowser(tabfolder folder, string html) {     tabitem item = new tabitem(folder, swt.none);     composite c = new composite(folder, swt.none);     item.setcontrol(c);     c.setlayout(new filllayout());      browser browser = new browser(c, swt.none);      if (html != null)     {         browser.settext(html);         item.settext("original tab");     }     else     {         item.settext("new tab");     }      browser.addopenwindowlistener(e ->     {         e.browser = addnewbrowser(folder, null);     });     browser.addvisibilitywindowlistener(new visibilitywindowlistener()     {         @override         public void hide(windowevent e)         {             browser browser = (browser) e.widget;             shell shell = browser.getshell();             shell.setvisible(false);         }          @override         public void show(windowevent e)         {             browser browser = (browser) e.widget;             final shell shell = browser.getshell();             if (e.location != null) shell.setlocation(e.location);             if (e.size != null)             {                 point size = e.size;                 shell.setsize(shell.computesize(size.x, size.y));             }             shell.open();         }     });     browser.addclosewindowlistener(e ->     {         browser browser1 = (browser) e.widget;         shell shell = browser1.getshell();         shell.close();     });      folder.setselection(item);      return browser; }
