jList like a FileListBox

[Radu]

Hello!
Can someone help me with the code to make a jList that is showing the files from a folder?
From example to show *.* from D:\Test in a jList or something similar to a ListBox or FileListBox from Visual Basic.

Your best bet is to go through the Sun tutorials on JList and on File handling, then try to play with some code, and come on back posting your code if you run into a problem and let's see what we can do with it.

I made this to show all files from a specified folder but I want to see them in a jList or something like that as I sad and NOT in a tree like in tutorials.

I bet you haven't even skimmed through the API documentation because this is just a no-brainer: new JList(new File("D:/Test").list()); of course you can add more bells and whistles to this tiny code snippet. Always first study the tutorials (as has been suggested by Fubarable) and study the API documentation. If you don't you keep on asking for the obvious.

kind regards,

And that's why I included the JList tutorial! You are allowed to look at more than one tutorial and combine the information in your brain. :)

1) What line should I delete to show me only the files -- without details (bytes) and without folders?

2) Were should I modify the directory that is listed (I need to view files from D:\Test)?

1) What line should I delete to show me only the files -- without details (bytes) and without folders?

2) Were should I modify the directory that is listed (I need to view files from D:\Test)?

I bet that is not your code: you don't understand it and you're behaving like a surgeon: cut away bits and pieces and hope for the best. This is not the way you develop a program. Have a look at that code snippet I supplied; most likely it doesn't do all you want; you have to read the API documentation (I bet you didn't do that either yet) and construct the code you want. I gave you a starting point.

kind regards,

Jos

[Radu]

of course is not my code.

where should i put that new JList(new File("D:/Test").list()); code in the program?

[JosAH]

of course is not my code.

where should i put that new JList(new File("D:/Test").list()); code in the program?

You don't need any other code: that snippet gives you a JList properly initialized with all entries from the D:/Test directory. Put that list whereever you want. It is next to impossible to stick that code snippet in a large piece of code that doesn't anticipate for it. Please read the API documentation and stop guessing and begging to be spoonfed.

kind regards,

Jos

OK! I managed to do that.
Now I don't know another thing.
How can I see in 2 jLists all files from 2 different folders by clicking one item in another jList.

Basically I have 3 jList:
jList1 with items: item1, item2 and item3
and jList2 and jList3 in wich will be displayed 2 different folders.

If I click item1 in jList1 in jList2 will be displayed *.* from d:\trs\item1 and in jList3 will be displayed *.* from d:\rec\item1


If I click item2 in jList1 in jList2 will be displayed *.* from d:\trs\item2 and in jList3 will be displayed *.* from d:\rec\item2



P.S. If you don't uderstand I can attach my code to this post to see my project.

[Fubarable]

The JList tutorials that I linked to above will help you react to the user's selecting an item in your first list. I would recommend that your JLists each use a DefaultListModel (<-- to API link) as their models and then based on the first list's selection use this information to fill the models of the other two JLists by calling the models' addElement method.

Why not give it a try, and if you hit a snag, come back with your code. We'd best be able to analyze your code if it is in the form of an SSCCE (also linked above).

Best of luck.

Hmmm... Nobody?

[Fubarable]

Hmmm... Nobody?

Yes, you.

You've got borrowed code that you can't understand, and I doubt anyone is going to have the time to go step-by-step through this code that's not theirs. The best solution to this problem is to either write code you do understand or do enough reading so you understand the borrowed code. Much luck.

[Radu]

Some of you java programmers suck (Fubarable is one of them). I don't know what is making you so selfish.


I REALLY DON'T CARE IF YOU WILL BAN MY ACCOUNT!

[coltragon]

wow, 2 days ago, you didn't know anything about the file functions.
and now you can write that program, you're a fast learner ;)

of course, if you STEAL a code from someone else, you won't understand it

[Radu]

I don't want to learn any java. I know vb.net and c++. I want to create this program to help me in my work. I alleady done it in vb.net but i can't run it at my work beacuse i don't have any vb or c++ there and I don't work as a programmer

[coltragon]

you can't compile it too an exe?

[JosAH]

I don't want to learn any java. I know vb .net and c++. I want to create this program to help me in my work. I alleady done it in vb.net but i can't run it at my work beacuse i don't have any vb or c++ there.

So install C++ and/or VB 'at your work'; the Microsoft Express editions are free downloadable editions. Goodbye.
