[news.eclipse.platform.swt] Re: TreeViewer with lazy loading

[thomas.larsson@xxxxxxx (Thomas Larsson)]

Thanks Stefan,

I'm a little confused so let me describe the problem in more detail. In my 
case, I have a checkboxtreeviewer which displays the file tree. I have a 
CheckStateListener that calls the CheckBoxViewer.setSubTreeChecked() if 
the user checks a file.
If the file tree is large and a top node is checked, there is a 
considerable lag with an unresponsive gui. How does this correspond to 
what you said?

If you need to know,
My ContentProvider has the getChildren method:

	public Object[] getChildren(Object element) {
		
		Object[] kids = null;
		if( useFilter)
			kids = ((File) element).listFiles(fileFilter);
		else
			kids = ((File) element).listFiles();
		return kids == null ? new Object[0] : kids;
	}

Best Regards
