    Try using the javac compiler to get some good error messages that you can copy and paste here. Your IDE does not give good compiler error messages.

    You need to find and fix the error. You should not ignore it.

    Yes, I think any component can be a drop point (with the proper coding)

    It appears that you didn't have this drag and drop thing as wired as you originally thought, and I can't see that you've made any progress in this thread. To move forward, I suggest you post some code, describe the problems you're having with errors or descriptions of what is not working well, etc. Short study programs that take small steps from which to learn are more useful for discovery, practice, and sharing of new skills with others than a large project that has lots of moving parts, all of which may be in various stages of maturity.

    As always, keep coding and good luck!

    i learnt drag and drop with textfield, not label to label so that is why i thought i just needed to change the code around but its not as easy as i thought. doing some research so when i'm done i will post somthing, but it seems to me as though you cannot do a label to label

    Try changing the code in post#11 by replacing the text field with a label.

    it doesnt work
    It doesn't work because it has syntax errors and will not compile. You need to find and fix the errors in the program so that it compiles without errors.
    You can not test code that does not compile.

    Try making a few, simple changes to the code in post#11. There isn't any code like what you posted in #40 from post#11.

    --- Update ---

    [/COLOR]i have done a whole days of worth of research and i don't think that a label can be a drop target... if anyones any different please can you help me

    --- Update ---

    I don't really have to add a JLabel it can be a textfield too but the thing is i dont know how make it so it the Textfield only accepts the jlabel if it matches the image.

    The drop target component needs a String that can be compared to the dragged String.

    For testing change the simple program you have working to have a String associated with the drop target so that it can accept one of the Strings from the drag source labels and reject the other.

    Sorry, I don't know what you mean by "key".

    What is the "string bit"? I assume that you know how to define a constructor for a class that takes a String as argument and that you know how to call that constructor and pass it a String.

    how do i get it to accept the drop if it matches the image?
    What does that mean? How will the code determine if there is a match?

    Start by making a small change to the code from post#11. Change it so that the drop target only accepts a drop from one of the two drag sources and rejects a drag from the other source.
