    Default 2D JButton Array

    Okay, so basically i am creating a Level Editor and i have two seperate JPanels on the JFrame. I want to be able to select a tile which is also a button from one JPanel which will have its own ID and then click on a space/button on the other JPanel which will then set that place in the array to the ID of the tile from the other JPanel and also set the image to the one attached to the ID (eg. grass - ID 0). After i've created the level it will be printed to a text file which will then be read by the engine.

    Am i doing this the right way or is there a better way of doing this?
    Thank you!!

    Level Text File / Array:
    0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 
    0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0

    I'm not really sure what your question is...? Are you asking us if this approach works? The only way to answer that is to write the code and see what happens.

    I personally probably wouldn't use JButtons. Why can't the user just click directly in the JPanel that's showing the tiles?

    I'm asking whether the button approach would work, and if not, what is a better way exactly?
    With your question, well one panel pretty much handles what tile will be placed and the other panel is the position of the tile.

    I just have no idea what the best way to display the tiles on both panels is!
    Do you get what i mean?

    The button approach might work. The only way to answer it is by coding it up.

    I'm not sure why you're displaying the tiles on both panels, but only letting the user click one of the panels. Why not let the user click the panel directly?

    One "Tilesheet" panel shows the available tiles to place on the other "Map" panel. The "Map" panel shows the images in a grid, say 48x48. When a tile is placed on a position, that position in the array will change to the selected tile's ID.
    Sorry if i am repeating myself.

    I would advice you to create your own custom component that will paint these things by itself.

    I'd use buttons initially because they have so many features that would be useful. Later if the response time or the spacing gets to be a problem, create your own custom objects.
    If you don't understand my answer, don't ignore it, ask a question.
