welcome to the forum :-) While you are at learning, please learn java naming conventions as well and stick to them — kleopatra, Feb 08 '12 at 11:26
@AndrewThompson if i use renderer means i create separate class,so that. — javalearner, Feb 08 '12 at 11:30
So what? What is the problem? If code creates another class, or causes it to be created (by default, or by using another class), it is a trifling thing. If code creates so many extra objects that it throws an `OutOfMemoryError`, that is a problem. — Andrew Thompson, Feb 08 '12 at 11:41
@AndrewThompson class FRM_FLXD_ICON_ASSGN extends DefaultTableCellRenderer { ImageIcon Icon; public Component getTableCellRendererComponent( JTable table, Object value, boolean selected, boolean focus, int row, int col) { if(selected == true){ Icon=new ImageIcon(getClass().getResource("Pointer.gif")); } else{ Icon=new ImageIcon(getClass().getResource("Blank.gif")); } this.setIcon(Icon); return this; } } if i use this, the blank image set whole table column.just i click one column it will display pointer.gif — javalearner, Feb 08 '12 at 11:47
@AndrewThompson how to change ,if i select one row the pointer.gif will display in that particular cell.then i click another row the pointer.gif will show in that place. the previous select cell will display Blank.gif.How to prevent to set blank.gif in all cell of column(0) — javalearner, Feb 08 '12 at 11:55
I cannot read code in comments. Please edit it into your question, select the code and click the `{}` button above the message editing form. — Andrew Thompson, Feb 08 '12 at 12:01

JTable know Icon/ImageIcon Object, then you can add Icon/ImageIcon directly to the JTable, example

what are the changes needed in the above coding for display the image? – javalearner Feb 08 '12 at 11:20
just downvoted your example (how could I possibly have missed that :-) – kleopatra Feb 08 '12 at 11:25
Nice example, but what is with the `EventQueue.invokeLater(new Runnable() { public void run() { } });`? (Empty runnable) – Andrew Thompson Feb 08 '12 at 11:27
@Andrew Thompson :-) maaaaay beee I removed some code, maaaybe nothing, who's know what rice I smoked on this day, I have to .... thanks !!! – mKorbel Feb 08 '12 at 11:32
