Java expert help needed - Code attached
Hi experts,
Please find attached the file which can be run to view the output. When you view the output, you can notice two text fields and a browse button corresponding to each text field. I need to modify this in such a way that, I do not want to browse and find the input file, instead I just need to drag and drop a file to this textfield, such that, the file path comes there. Also, I should have the option to type the path of the file.
Any help in this regard which provides me the perfect solution would be much appreciated with points.
Regards,
Sree

well drag and drop for swing elements is posible, but not really "easy" there is a complete tutorial here, check it out,
Drag and Drop is possible fomr one java component to another - but from system window to java application - well, everything is possible
but it is problematic. You can probably do something through clipboard, but direct drag into Java window from say your desktop
seesm difficult

>>As to drag the file - do you mean you want to drag the file from outside your java application - say from Windows folder window?
Yes, I want to drag file and drop it inside textfield, so that, the path comes there automatically.

But you want to take the file say, from your desktop, or from say JFileChooser window?
Waht is your OS ?

this is also maybe a little more simple example:

pls, any code snippet which would prove to be an apt solution is much appreciated.
see code above
There is no problem with typing file path in the textfiled - what kind of doubts you have on this subject - just type, and
then use getText() method and use the string whicvh you get as a file name
As to drag the file - do you mean you want to drag the file from outside your java application - say from Windows
folder window? That seems problematic to me.
