swing - Labeling buttons and maintaining dimensions -
i struggling jbuttons, keeping them same size, seems adding button causes stretch accommodate said addition.
as result, button labeled 'yes' won't same size button labelled 'no', if while blank both buttons should have been more large enough comfortably contain either string.
essentially, know whether there way label buttons without altering dimensions of said buttons.
i employing gridbaglayout, here relevant sample of code reference:
edit
i managed effect looking using icons... won't able see in it's entirety, calling icons directly hard drive... regardless, i'll leave completed code reference...

can add more code , perhaps screenshot show application looks (see stackoverflow.com/help/mcve more details on ideal code example on stack overflow like)?
i prefer use sub panels simple layout managers on using single panel large number of components , complex layout manager. consider using multiple panels and/or different layout managers (this nice overview of of layout managers available default: a visual guide layout managers.)
as short example, piece of code creates panel 2 buttons using gridlayout (with gaps , border add spacing):
import java.awt.*; import javax.swing.*; import javax.swing.border.*; public class buttonwidths { public static void main(final string[] arguments) { swingutilities.invokelater(() -> new buttonwidths().createandshowgui()); } private void createandshowgui() { final jframe frame = new jframe("stack overflow"); frame.setbounds(100, 100, 240, 200); frame.setdefaultcloseoperation(windowconstants.exit_on_close); final jpanel panel = new jpanel(new gridlayout(2, 1, 28, 28)); panel.setborder(new emptyborder(28, 28, 28, 28)); final jbutton yesbutton = new jbutton("yes"); final jbutton nobutton = new jbutton("no"); panel.add(yesbutton); panel.add(nobutton); frame.getcontentpane().add(panel); frame.setvisible(true); system.out.println("yesbutton: " + yesbutton.getsize()); system.out.println("nobutton: " + nobutton.getsize()); } } setting minimum size?
the gridbaglayout should use button's minimum (and/or preferred) sizes, might way make width of buttons equal; gridbaglayout documentation:
in addition constraints object, gridbaglayout considers each component's minimum , preferred sizes in order determine component's size.
however, search returned several stack overflow discussions using minimum size advised against:
