Comment Box

[Razer13]

Hi,

I have been trying to look for some code to add a comment box where people can add or delete comments in my program when viewing items any ideas pls?

[stultuske]

you may want to be a bit more specific

I assume using a textArea to write one, a Button to add it to your savedComments, and a small 'X' button in a subpanel that contains a comment linked to a deleteThisComment function would do the trick.

that is, if you are working in a Swing application, if you are in a webapp, it's another story

yes i am using a swing application. i am require to store comments with the ability to add / delete comments with a timestamp on each comment which are stored on a text file. Please check your pm with further information regarding the matter.

thanks in advance

adding to what stultuske said, assuming you have a text area added to your gui, and its name is jTextArea1, and a button to add the comment say jButton1. you would add an ActionPreformed event to the button and in this method the button will use:

String comment=jTextArea1.getText();

That will now save what the user typed in the textarea, now you would save it to a file:http://www.daniweb.com/software-development/java/threads/94567 that may help you accomplish that. as for viewing the comment next time, your textfile should contain some structure to allow you to see if it has a comment and then print it to the textarea using:

String comment="";//this will be the comment found in the text file
jTextArea1.setText(comment);

To find the comments you'll have to read in the text file with the saved comments...take a look at:http://www.roseindia.net/java/beginners/java-read-file-line-by-line.shtml

hope that helps to get you going, oh and if you dont know how to write action listeners for jbuttons here:http://docs.oracle.com/javase/tutorial/uiswing/events/actionlistener.html
