swing - Trying to set the location of a Java Button using JFrame isn't working? -

please below edits.

so i've looking on numerous "solutions" fix problem, can't seem working.

this application looks code below:

basically, want set location of button, can't manage so. here code:

package me.cervinakuy.application;  import java.awt.borderlayout; import java.awt.color; import java.awt.gridlayout;  import javax.swing.imageicon; import javax.swing.jbutton; import javax.swing.jframe; import javax.swing.jpanel;  public class controlpanel3 extends jframe {      jpanel panel = new jpanel();      jbutton startrobo = new jbutton();     jbutton stoprobo = new jbutton();     jbutton restartrobo = new jbutton();      public controlpanel3() {  //      setlayout(null);         setsize(1000, 700);         setresizable(false);         setlocation(450, 150);         setdefaultcloseoperation(jframe.exit_on_close);         getcontentpane().setbackground(new color(45, 48, 55));         settitle("espin software | control panel");         setvisible(true);          startrobo.seticon(new imageicon(getclass().getresource("/resources/startrobo.png")));         stoprobo.seticon(new imageicon(getclass().getresource("/resources/stoprobo.png")));         restartrobo.seticon(new imageicon(getclass().getresource("/resources/restartrobo.png")));          startrobo.setborder(null);         stoprobo.setborder(null);         restartrobo.setborder(null);          startrobo.setlocation(100, 100);          panel.add(startrobo);         panel.add(stoprobo);         panel.add(restartrobo);         panel.setopaque(false);          add(panel);          validate();      }  } 

edit: i have managed create gui of looking for, however, have new problem. buttons pressable different parts of gui, rather on image. interested, here have been able accomplish:

new gui look.

updated code:

package me.cervinakuy.application;  import java.awt.color; import javax.swing.imageicon; import javax.swing.jbutton; import javax.swing.jframe; import javax.swing.jpanel;  public class controlpanel3 extends jframe {      jpanel panel = new jpanel();      jbutton startrobo = new jbutton();     jbutton stoprobo = new jbutton();     jbutton restartrobo = new jbutton();      public controlpanel3() {  //      setlayout(null);         setsize(1000, 700);         setresizable(false);         setlocation(450, 150);         setdefaultcloseoperation(jframe.exit_on_close);         getcontentpane().setbackground(new color(45, 48, 55));         settitle("espin software | control panel");         setvisible(true);          startrobo.seticon(new imageicon(getclass().getresource("/resources/startrobo.png")));         stoprobo.seticon(new imageicon(getclass().getresource("/resources/stoprobo.png")));         restartrobo.seticon(new imageicon(getclass().getresource("/resources/restartrobo.png")));          startrobo.setborder(null);         stoprobo.setborder(null);         restartrobo.setborder(null);          panel.setlayout(null);         startrobo.setlocation(200, 200);         startrobo.setbounds(5, -95, 300, 300);         stoprobo.setbounds(5, 0, 300, 300);         restartrobo.setbounds(5, 95, 300, 300);          panel.add(startrobo);         panel.add(stoprobo);         panel.add(restartrobo);         panel.setopaque(false);          add(panel);          validate();      }  } 

there typically number of ways layout components end same effect. in example, use panel contain buttons in column (buttoncontainer using gridlayout) panel restrict container top (buttonconstrainpanel using borderlayout) container put panel on left (ui borderlayout).

it achieved using single gridbaglayout or grouplayout, though logic of achieving might not simple.

the focus border seen on blue button indicates limits of mouse click activate button.
