detect if JTable column contains string "blabla"

[mark goking]

which classes related to the JTable should i use so i can check if a table column contains a certain string

Hi Mark ,

I think you can use the DefaultTableCellRenderer class
And this class has a method
public Component getTableCellRendererComponent(JTable table,Object obj, boolean isSelected, boolean hasFocus, int row, int column)
You can ovrride the method and can check table value......

Thanks

hi tv, thanks. yes you are right.

but what i want to do is something like this

jTable.getColumn("column_name").doesStringExistInColumn(); returns boolean

something like that.

Not really.
The renderer is like a rubber stamp for the visualization part and the method you mention returns a visual component.
Remember MVC. The visualization should be independent of the data.

The proper way to do it would be to query the table model for the required data.

thanks.

been searching but found no possible way to shorten the solution. so i used getValueAt() and checked each row of the tablemodel.
