java - GridBagLayout Troubleshooting -


so decided make gui bit nicer, , use gridbaglayout instead. following objects adding panel:

choosepanel = new jpanel(); choosepanel.setlayout(new gridbaglayout());  chooselabel = new jlabel("choose quarter input data for:"); additem(chooselabel, 0, 0, 1, 1);  qgroup = new buttongroup();      q1 = new jradiobutton("q1");     qgroup.add(q1);     q1.setselected(true);     additem(chooselabel, 0, 1, 1, 1);      q2 = new jradiobutton("q2");     qgroup.add(q2);     additem(chooselabel, 0, 2, 1, 1);      q3 = new jradiobutton("q3");     qgroup.add(q3);     additem(chooselabel, 0, 3, 1, 1);      q4 = new jradiobutton("q4");     qgroup.add(q4);     additem(chooselabel, 0, 4, 1, 1);  choosebutton = new jbutton("press enter quarter");     choosebutton.addactionlistener(e->{         cl.show(mainpanel, "info");         this.setsize(330, 240);     });     choosebutton.setpreferredsize(new dimension(200, 100));     additem(chooselabel, 1, 1, 1, 1);      resetbutton = new jbutton("reset previous data");     resetbutton.addactionlistener(e->{      });     resetbutton.setpreferredsize(new dimension(200, 100));     additem(chooselabel, 1, 2, 1, 1);

and here "additem" method:

private void additem(jcomponent c, int x, int y, int width, int height){     gridbagconstraints gbc = new gridbagconstraints();     gbc.gridx = x;     gbc.gridy = y;     gbc.gridwidth = width;     gbc.gridheight = height;     gbc.weightx = 100.0;     gbc.weighty = 100.0;     gbc.fill = gridbagconstraints.none;     choosepanel.add(c, gbc); }

my problem is, when run program, shows chooselabel in middle of screen, , nothing else. know how fix this? ......

change

q1 = new jradiobutton("q1"); qgroup.add(q1); q1.setselected(true); additem(chooselabel, 0, 1, 1, 1);  q2 = new jradiobutton("q2"); qgroup.add(q2); additem(chooselabel, 0, 2, 1, 1);  q3 = new jradiobutton("q3"); qgroup.add(q3); additem(chooselabel, 0, 3, 1, 1);  q4 = new jradiobutton("q4"); qgroup.add(q4); additem(chooselabel, 0, 4, 1, 1);

to

q1 = new jradiobutton("q1"); qgroup.add(q1); q1.setselected(true); additem(q1 , 0, 1, 1, 1);  q2 = new jradiobutton("q2"); qgroup.add(q2); additem(q2, 0, 2, 1, 1);  q3 = new jradiobutton("q3"); qgroup.add(q3); additem(q3, 0, 3, 1, 1);  q4 = new jradiobutton("q4"); qgroup.add(q4); additem(q4, 0, 4, 1, 1);

and on.. adding chooselabel time.
