[SOLVED] method not applicable for the arguments

jon80 · #1 (**permalink**) 05-30-2009, 04:37 PM

I have a littel problem with the code, since the arguments I am passing to a stub do not seem to be valid:

Code:

chooser.setFileView(new FileIconView(filter, new ImageIcon("C:\\icons\\exit.png"))); //FIX

...

which calls

...
public void setFileView (FileIconView fileIconView) { //FIX
		//TODO stub
}

...
FileIconView is a class whose constructor requires:
public FileIconView(FileFilter aFilter, Icon anIcon)
	{
		filter = aFilter;
		icon = anIcon;
	}

...

NOTE 1: The code does not compile and might have other problems, but I have uploaded it as an attachment.

3 errors

Error 1:

Code:

icon = new ImageIcon(icon.getImage())
           .getScaledInstance(getWidth(),-1,Image.SCALE_DEFAULT);

You've misplaced a right parenthesis ")". The getScaledInstance method is being called on the ImageIcon instance instead of on its image argument.

Code:

icon = new ImageIcon(icon.getImage()
           .getScaledInstance(getWidth(),-1,Image.SCALE_DEFAULT));
setIcon(icon);

Error 2:

Code:

chooser.setFileView(new FileIconView(filter,
                        new ImageIcon("icons/exit.png")));

The argument for the setFileView method is/must be a FileView object.
You are supplying something unrelated. You might consider having the FileIconView class extend the FileView abstract class.

Error 3:
Typos.
Change

Code:

int result = chooser.showOpenFileDialog(ImageViewFrame.this);

to

Code:

int result = chooser.showOpenDialog(ImageViewerFrame.this);

Thank you I would never have seen my errors, for some reason
