how to open .drw or .prt file using swing?
Hi Everyone,
I am new to java programming n I m facing a problem in swing.I want to open a perticular drawing file using Java program but the condition is,it should open in the same window.Now,I have managed to open normal txt files n .doc files in the same window using JFileChooser and IO programming.But I dont know what it takes to open a .prt or a .drw file using the same program.
Can you guys plz help me out in this?I think,it is not compatible to open such files...but how to make it compatible then?
I m posting the code here...plz check it n help me out as soon as possible...Thank you very much......
