java - JoptionPane.showInputDialog Without cancel button and exit handle -


https://i.stack.imgur.com/lrdtn.jpg

i wanna kind of input dialog issue accept int type found `

 string[] options = {"ok"};  int selectedoption = joptionpane.showoptiondialog(null, panel, "the title", joptionpane.no_option, joptionpane.question_message, null, options , options[0]);

` i'd handle x(quit button red button close button) because causes exception errors caused

i'm using regex.matcher

at java.util.regex.matcher.gettextlength(unknown source) @ java.util.regex.matcher.reset(unknown source) @ java.util.regex.matcher.<init>(unknown source) @ java.util.regex.pattern.matcher(unknown source)

thanks

existing solution

you use inputdialog of joptionpane

string res = joptionpane.showinputdialog(null, "enter name", "the title", joptionpane.question_message); system.err.println(res);

be aware of result null if user closed dialog or hasn't inserted text.

but solution isn't exactly looking dialog want have. have create own joptionpane.

own solution

i recommend use modal jdialog , remove frame (that causes problems you) with

.setundecorated(true)

or override dispose() in own class handle it

@override public void dispose() {     //your code     super.dispose(); }

the begin of own class this:

public class myoptionpane extends jdialog {     public myoptionpane(dialog owner, boolean modal)     {         super(owner, modal);         this.setundecorated(true); //remove frame     } }

go on these steps:

  1. add label "enter name" gui
  2. add textfield gui
  3. add ok button gui (with actionlistener)
  4. attach actionlistener @ "ok" button
  5. fetch textfield value on "ok" click, return , dispose jdialog

comment post if have questions or remarks.

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 ...
