how to drage my card images draw on applet.

[ganesh.gothi@gmail.com]

Hi,
I want to drag and drop my card images on applet, I have successfully draw images on applet and now I want to drag it, please help me, what can I do for this.

[Norm]

Try using a mouse listener and a mouse motion listener.

Try using a mouse listener and a mouse motion listener.

I have implement both mouse listener and a mouse motion listener in my program and extends with JApplet,

I have perform some code for drag images but not dragging images....
Code executed in mouseDragged and mousePressed method, but not working....

[Norm]

but not working..

Hard to say what the problem is. I can not see the code and there are so many ways for programs to not work.

[ganesh.gothi@gmail.com]

what can I do?, please check my code at once.........

[Norm]

What code?

Have you tried debugging the code to see what it is doing? Add lots of printlns to show where the code is executing and the values of variables every time theor values are changed. the print outs will help you understand what the code is doing.
I don't have the images an can not test the code.

[ganesh.gothi@gmail.com]

Please edit your code and add code tags.

CODE tags not QUOTES

Yes , I have tried with put println in my code, but I am not getting what is the problem, that's why I am sharing my problem with you,,,please solve my problem.

I am using eclipse , you want to images for testing this code?

[Norm]

I am trying to help you solve your problem.
Can you post the debug output that shows how the code is executing and the values of the variables as they change.

Please explain what the code does when it executes and describe what is wrong with what it is doing.


Can you attach a zip with the images?

[ganesh.gothi@gmail.com]

In the above code I am trying to develop card game for the user to play, In this code I have draw 10 cards up ( g.drawImage(c.image,x2[j],y2[j], this); ) by and 10 cards down by (g.drawImage(c.image, x1[j],y1[j], this );) and 1 cards in the center on the applet, now the remaining 83 cards of 104, will be displayed on the center as I want. now I want to drag this 83 cards one by one as game will be played and also drag 10 cards that is draw bellow side at
(g.drawImage(c.image, x1[j],y1[j], this );) will be dragged.
So now I want to drag 83 cards one by one, please help me...........

[Norm]

I want to drag this 83 cards one by one

Please post the debug output that shows what is happening when you execute the code and try to drag a card.
Does the card move any? Explain what happens when you try to drag a card.

I can not test without the images.

[ganesh.gothi@gmail.com]

I am not attaching zip file, please download from the URL, please download cards20.zip file show in red color, please download this and test it.......

Java: Example - Card Demo

[Norm]

Please attach a zip. I don't go to third party sites.

Please answer my questions:

Please post the debug output that shows what is happening when you execute the code and try to drag a card.
Does the card move any? Explain what happens when you try to drag a card.

[ganesh.gothi@gmail.com]

I am using applet tag in html for showing applet on browser. when I am run my above code , it shows all 104 cards and its arrange as 10 up, 10 down, 1 center and remaining 83 also in center as required, now i want to drag first card into 83 cards that is show in top position and drop into other location, this is I am trying to do,,,,,,,,,please help me.......

[Norm]

Please post the debug output that shows what is happening when you execute the code and try to drag a card.

I need the images to test the code.

I am not attaching a zip file can I use insert images tag for for insert images for your test code..?

[Norm]

How do I test the code without images? If you have a version of the code that does not require images, please post it.
Otherwise I can do nothing more.
