问题 I have two questions. 1. How to make app remember new order in ListView what I made with drag and drop. Like now I can reorder items but every time I open app, I have to reorder items again. 2. My app should open different webpage from each item. But when I reorder items then web links doesn't reorder. They stick on same. Like example: I have items Google and Yahoo! so links are "http://google.com" and "http://yahoo.com". Then I reorder item: Google was top but I drag Yahoo to top. After that

问题 Today I have been attempting to make a thumbnail up loader which uses drag and drop and the file API. I feel as if i have got reasonably far. But the DataURI that is provided to be the source in my image file ALWAYS returns as [object file] and therefore doesn't show the image. Any help?! Thanks. Danny (below is my code) <!DOCTYPE html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <style> #thumbnailPreview { width:149px; height

问题 I have a JTable and a JList and I have my code set up so that I can drag from the JTable to the JList using built in Swing methods.

Specifically, in the case of the source being a JTable, the image is just a border of the row I selected to drag. How can I override what this "image" is?
