TableModelEvent question: fires AFTER user has navigated away from cell, not what I need

Hello -

Another day in Java land. I am working on a little Swing/SQL application to hone my skills. It is for keeping data and pictures of chickens (I keep chickens)

It loads the data from the MySQL into a table using DefaultTableModel (will implement my own model later, on the ToDo list)

Now users can also show a picture of the chicken as filepaths are very annoying to type, I want to use a JFileChooser so users can select the picture, then save path into DB.

So I "bound" a TableModelListener to the table, once a TMEvent fires I ask it to check for the row/column if these match the picture cell (selection of course set to single_selection) it starts the JFileChooser. However, this only starts AFTER a users has navigated away or hit "enter" in the table text cell that holds picture data. I want it to start right away, "on click".

Is there a simple way to do what I want, or will it be Swings and roundabouts? If there's a class/interface or combination thereof, just say which ones to use and I will try to figure out the rest myself.

Thanks for reading

See code below.



Woohoo passed SCJP 1.6, that's the theory exam passed now for the practice ;)

If you are saying that the user can select any image from anywhere on the file system, then using a JFileChooser may be the best approach. However instead of using a TableModelListener you will need to use a "custom editor" to display the file chooser. Read the JTable API and follow the link to the Swing tutorial where you will find an example that display a JColorChooser as the editor. You should be able to customize the code for the file chooser.

If you are limiting the user to select an image from a given directory, it may be easier to use a combo box as the editor and to preload all the images into the combo box. Then the user can just select the image from the combo box.

Ah makes sense, don't use the table but use the component that displays the image to "listen" and open the JFileChooser.

That will work, thank you
