java - Position glCanvas alongside a JPanel containing buttons -

-

i'd have jbutton panel consume ~30% of frames horizontal space.
, glcanvas on right side taking rest of frames space.
how can achieve layout?

currently:

enter image description here

main.java

glprofile profile = glprofile.get(glprofile.gl2); glcapabilities capabilities = new glcapabilities(profile);  glcanvas glcanvas = new glcanvas(capabilities); glcanvas.addgleventlistener(new gamerenderer()); glcanvas.setsize(100, 100);  jframe frame = new jframe("tool");  jpanel panel = new jpanel(); jpanel cpanel=new jpanel(); panel.setlayout(null); cpanel.setlayout(null);  jbutton buttonbr = new jbutton("1"); jbutton buttone = new jbutton("2"); jbutton buttonr = new jbutton("3"); jbutton buttonc = new jbutton("4"); jbutton buttont = new jbutton("5"); jbutton buttoncr = new jbutton("6");  buttonbr.setbounds(10, 30, 150, 40); buttone.setbounds(10, 80, 150, 40); buttonr.setbounds(10, 130, 150, 40); buttonc.setbounds(10, 180, 150, 40); buttont.setbounds(10, 230, 150, 40); buttoncr.setbounds(10, 450, 150, 40); cpanel.add(glcanvas);  panel.add(buttonbr); panel.add(buttone); panel.add(buttonr); panel.add(buttonc); panel.add(buttont); panel.add(buttoncr);     frame.add(cpanel); frame.add(panel);  frame.setsize(toolkit.getdefaulttoolkit().getscreensize().width, toolkit.getdefaulttoolkit().getscreensize().height); frame.setvisible(true);  animator animator = new animator(glcanvas)); animator.start();

consider using miglayout such:

import javax.swing.jframe; import javax.swing.jlabel; import net.miginfocom.swing.miglayout; import javax.swing.jtextfield;  public class main extends jframe {     private static final long serialversionuid = 1l;      public main() {         getcontentpane().setlayout(new miglayout("", "[grow 30][grow 70]", "[]"));         jlabel label = new jlabel("30%");         getcontentpane().add(label, "cell 0 0");         jtextfield textfield = new jtextfield("70%");         getcontentpane().add(textfield, "cell 1 0,growx");         pack();         setvisible(true);     }      public static void main(string[] args) {         new main();     } }

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
