hi ranches,

i developed a program to display the files in selected directories or folders using jtree and jtable..
i have a jdialog which gets the folder from the user..
i have no problem while choosing the folder for first time..
but when i again choose another folder the new files get append with the last displayed files...
i have tried lots of methods to refresh the jtable when the user selects the open dialog ..........

here is my code:
// this is for opening the jdialog:

//this s for showing the files list in jtable and jtree

code for jtree

my own table model code

need help...

if you really want help, you'd post something we can copy/paste/compile/run and see what you see.

if you just want us to read your snippets, well, I'd prefer to go to the library

problem am getting is when we choose new directory or folder, the files in selected folder get append with the jtable value ...

i have tried few methods to do it such as fireTableDataChanged etc. but nothing happened..
what i should do to refresh jtable every time while user chooses new folder/directory?...

We don't want full code files, we want SSCCEs.

Create a new instance of your table model, put your data into it, and call the JTable's setModel method.
I agree. Here's the link:
