eclipse - porting java program from windows to linux: invisible java swing elements in main frame on linux only -


so trying port large java program windows linux (centos 7). program works fine on windows, in linux set main frame of application shows (title, maximize minimize exit buttons found on top bar of applications). java swing elements (buttons, tables, drop down menus) invisible @ frame (clicking on them bring invisible menu). again works fine on windows, isn't code.

things i've tried:

-attempt: trying run different program wrote has a java swing
gui

result: same problem.

conclusions: not code problem

-attempt: downloading simple gui example works on windows

result: same problem

conclusions: not code problem

-attempt: downloading simpler gui example works on windows

result: same problem

conclusions: not code problem

-attempt: reinstall java (yum remove, yum install)

result: same problem

conclusions: don't know draw this, not installation of java?

-attempt: reconfigure build , classpaths

result: same problem

conlusions: don't know draw this, not build , classpaths?

-attempt: new centos 7 vm , reinstall on there

result: same problem

conlusions: centos have problem swing?

useful? random facts:

java -version returns openjdk runtime environment (build 1.8.0_141-b16) openjdk 64-bit server vm (build 25.141-b16, mixed mode)

which java returns /usr/bin/java

whereis java returns java: /usr/bin/java /usr/lib/java /etc/java /usr/share/java /usr/share/man/man1/java.1.gz

i'm using eclipse oxygen standard edition java run , compile

under run configurations jre set java-1.8.0-openjdk-1.8.0.141-1.b16.el7_3.x86_64

runtime classpath, source, environment default.

buildpath includes libraries otherwise default.

my firefox gui broken (the tabbar transparent) wonder if has it

the buttons work on gui, invisible.

i uninstalled , reinstalled java , mariadb

i tried building apache ant.

i did export java_home @ 1 point don't think it's set anymore because nothing if echo $java_home. ant seems think /usr/lib/jvm/java? don't know.

suspicions: -incorrect java installation/versioning

-corrupted gnome gui

-i messed somthing when did yum update/all yum installing , reinstalling did.

-swings setlookandfeel function, although unlikely because doesnt work simple programs dont use that

fairly new everything. software engineering, community, etc.

edit

here piece of code produces same invisible button problem on linux computer works on windows:

package com.zetcode;  import java.awt.container; import java.awt.eventqueue; import java.awt.event.actionevent; import javax.swing.grouplayout; import javax.swing.jbutton; import javax.swing.jcomponent; import javax.swing.jframe;  public class quitbuttonex extends jframe {  public quitbuttonex() {      initui(); }  private void initui() {      jbutton quitbutton = new jbutton("quit");      quitbutton.addactionlistener((actionevent event) -> {         system.exit(0);     });      createlayout(quitbutton);      settitle("quit button");     setsize(300, 200);     setlocationrelativeto(null);     setdefaultcloseoperation(exit_on_close); }  private void createlayout(jcomponent... arg) {      container pane = getcontentpane();     grouplayout gl = new grouplayout(pane);     pane.setlayout(gl);      gl.setautocreatecontainergaps(true);      gl.sethorizontalgroup(gl.createsequentialgroup()             .addcomponent(arg[0])     );      gl.setverticalgroup(gl.createsequentialgroup()             .addcomponent(arg[0])     ); }  public static void main(string[] args) {      eventqueue.invokelater(() -> {         quitbuttonex ex = new quitbuttonex();         ex.setvisible(true);     }); }

pictures:

functional buttons, invisible , on semi transparent jframe

not simple ones work

edit: tail -f /var/log/messages gives following 2 errors: "gnome-session: window manager warning: invalid wm_transient_for window 0x2e00004 specified 0x2e0001a (progress..)" , "window manager warning: buggy client sent _net_active_window message timestamp of 0 0x2200048 ()"

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
