Thread: Show files name in JFrame

Spoonfeeding is not helping.

OP- One of your basic problems is that you're passing the String to display into each ReadDirectory, but then you're drawing the String from your Start class, which for some reason is updated each time you read a file name.

You are also creating multiple JFrames for some reason, and you never add the ReadDirectory to your main JFrame.

Looks like I forgotten to change the String f on the Start class; instead of private String f; is static String f;.
Also I WANT to create multiple JFrames...maybe haven't explain clearly what I want...
The problem is that every frame have the file's title, but label is overited and is showing only the last file as in:

HTML Code:

Frame                          Frame_Title                     Frame_Label
1                                  a.txt                               c.txt
2                                  b.txt                               c.txt
3                                  c.txt                               c.txt

I want it to be:

Frame                          Frame_Title                     Frame_Label
1                                  a.txt                               a.txt
2                                  b.txt                               b.txt
3                                  c.txt                               c.txt

Again- You're painting Start.f, which you update each time you iterate, which means it will end up being the last value iterated over.

You want to use the String you pass in to ReadDirectory's constructor.

Why do you create an empty ReadDirectory in the ReadDirectory(String) constructor? You should be painting that supplied String.

I have this "idea" that paint() is been called from constructor with no parameters.
From your question can see that is totally not needed.

Indeed. I'd be curious to see what your code looks like after taking that into consideration. Feel free to post an SSCCE (thats a link).

Hi guys
My skill English is not good
But I understand main content of this thread is "Show files name in JFrame" as IIS GUI.

That is absolutely not how this works. If you want somebody to create the code for you, check out the Paid Java Projects forum from the main page. Otherwise, see the link in my signature before you post again.
