how can I do this? in just one click, one of my desired selected ROW will be selected?

i dont know how to implement this method >> getSelectedRows(), getSelectedColumn

[Darryl Burke]

Your question is regarding a JTable selection and you post code that deals with an ImageIcon, several menus and who knows what else. Definitely not the best way to get help on a public forum.

That's right, if you click on the JTable, then the row you clicked on will be selected. But that wasn't your question, was it? You seem to be asking how to make your program do something when a row is selected. If that's your question, then the API documentation for JTable (follow this link) has a link to the JTable tutorial very near the beginning. Follow that and start reading the tutorial. There's a section about "User Selections" which will probably answer your question.

I beg your pardon.. im sorry to make the title unclear or irrelevant to the posted code, .. what i want in my JTable is when i click a row, that row will be highlighted, but in this case i have an image Background in my Jtable,
Im having problems with that,

When I tried to remove the background , I can easily do that specific thing that I want, the whole row that I clicked was Highlighted, because of the background I cant see the highlight,
but I need to apply an Image Background in my JTable...

Is there anything to do with TableRenderer?

[Michael Dunn]

you've made each cell component transparent, so how do you expect it to show a highlight color?

perhaps changing your prepareRenderer code to set opacity in line with isRowSelected(row), might do what you want
