Is there a Java Swing component similar to "..."-Buttons in PL/SQL Developer? -


i want add button jtable. when button clicked, contents of corresponding cell should shown in new jtextarea. in pl/sql developer there such button, can see here:

clickable :

enter image description here

edit: tried this: 

public class testkonfigtablecellrenderer extends defaulttablecellrenderer {  @override public component gettablecellrenderercomponent(jtable table, object value, boolean isselected, boolean hasfocus,         int row, int column) {      jlabel l = (jlabel) super.gettablecellrenderercomponent(table, value, isselected, hasfocus, row, column);     jbutton openbutton = new jbutton("...");     l.add(openbutton);      return l;     } }

but doesn't seem work. did wrong ?

if "it not seem work", mean cannot click on button, expected.

the component returned renderer not added swing hierarchy. instead, painted representation used in table performance reasons. reason typical renderer returns same component after updating state. see "concept: renderers , editors" section in jtable tutorial more information.

there number of posts available on how include clickable button in jtable. example this one.

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 ...
