Class KPreviewWidgetBase

public class KPreviewWidgetBase extends QWidget

Abstract baseclass for all preview widgets which shall be used via KFileDialog.setPreviewWidget(const KPreviewWidgetBase ). Ownership will be transferred to KFileDialog, so you have to create the preview with "new" and let KFileDialog delete it. Just derive your custom preview widget from KPreviewWidgetBase and implement all the pure methods. The slot showPreview(KURL) is called every time the file selection changes.
