java - How do I put multiple JPanels (3) in a JPanel Using JTabbedPane? -
i trying create gui app using jtabbedpane create 5 tabs connected database. each tab contains panel 3 panels in (one panel hold jbuttons hold jlabels , jtextfields , last hold jtable. each south, center , north respectively). after creating tabs , components, last tab displays , displays incorrectly (it displays jlabels, jtextfields , jbuttons of 5 tabs). if remove tabs , leave 1 displays correctly if more one, displays on last tab. don't know how resolve it. please me.
the source code bit lengthy please bear me , me check it. if there better way write code please let me know.

i trying create gui app using jtabbedpane create 5 tabs. each tab contains panel 3 panels in it
as nature of swing components, can embed 1 jcomponent inside except jframe.
so, need create jpanel. make sure has gridlayout 3 cols , 1 row (or other way around, if need).
then, add 3 jpanels base jpanel has grid layout.
finally, add base jpanel jtabbedpane. have @ jpanel tutorial: http://docs.oracle.com/javase/tutorial/uiswing/components/tabbedpane.html
