Hi,
now I tried a long time to implement an JButton in a JTable-Cell.
I know that I've to write a CellEditor and a CellRenderer, and may be a TableModel.
I read the Swing-Tutoriel from Sun, but I really have problems with it. I looked in the examples but I doesn't understand it.
How is a CellEditor, a CellRenderer and TableModel built up?
What I've to do, to realize what I want?
How I implement what I've created?
Based on some examples I tried to rebuild the editor on my own :

Do anyone knows some other good sites or tutoriels about this?

Hi Lars,
I will do more than give you an example page. I can point you to some code that does exactly what you want!

Hi,
first thanks for the link.
I take the example an tried to rebuild it, but I've now another problem. I tried to put Images and JButtons together in the JTable.
Either I can the image or I can see thew Button, but not together.
What I'm doing wrong.
Here the code of my AbstractTableModel :

Hi,

Hi Lars,
I would say, it is. I have not done it, but you seem to be looking in the wrong place. As I see it, the example I pointed you to does this:
table.getColumn( "Button" ).setCellRenderer( new ButtonRenderer() );
There should be nothing to stop you from doing the above and the following:
table.getColumn( "Image" ).setCellRenderer( new ImageRenderer() );
Each renderer should implement getTableCellRendererComponent and return itself after setting somethings.
Regards,
Manfred.

Hi Manfred,
thanks for your help, it works! The table is now showing images and buttons
But i've another last question, sometimes the table shows the text, not the buttons. What can be the reason??
Regards
Lars
