passing data into an applet

[johnnyv]

Hello I am new to java so bare with me

I hav created a java applet to display images stored in a folder.

currently the applet displays all of the images

I would like to be able to have the applet display only the images that I choose. I would like to be able to pass in the name of the images to be displayed

can this be done?

How do you pass information ie names of files into a java applet?

thanks

Easy...
beetwin <applet></applet> tags insert tag that looks like <param name=&quot;filename&quot; value=&quot;blablabla.gif&quot;>. Applet have function: String getParameter ( String ); so to get &quot;blablabla.gif&quot; simply write something like this: getParameter ( &quot;filename&quot; ); This function will return String with value &quot;blablabla.gif&quot; or null if no such parameter was found! For example if I will write getParameter ( &quot;aaa&quot; ) then I will have null on return because there is no such parameter in HTML file ( no string like <param name=&quot;aaa&quot; value=&quot;&quot;>. Thats all...

Thanks for your reply

let me modify the orginal question abit if I could

my web page will have 3 different buttons on it and 3 seperate folders containing images.
Depending on the button pressed I would like to have the applet display the images in the corresponding folder

ie if button 1 is pressed display the images in folder 1 only, if button 2 is pressed display the images in folder 2 etc

So I would like to be able to pass in the image names and path depending on the button pressed

Can I do this??

thanks again for the responce

Write a public method in your applet with image_name and path parameters and call this method (from JavaScript) when a button has changed.
I posted some example about a year ago . If you need more specific, try to find it (key words: from data to java applet).
