问题 Using Flash CS5 I came across something odd today. The UIScrollBar component has the rigid width of 15px. When you add it to a container such as a Sprite, you'd expect the width of the sprite to return 15, but it returns 100 instead! Here's an example code. import flash.display.Sprite; import fl.controls.UIScrollBar; var spr:Sprite = new Sprite(); addChild(spr); trace('spr.width:',spr.width); var bar:UIScrollBar = new UIScrollBar(); spr.addChild(bar); trace('bar.width',bar.width); trace('spr

问题 I need help in scrolling to highlighted text/string positions in a rich text box. I was able to find text and highlight it but I want the user to be able to click on a Next button and that event to scroll to the vertical offset position of the first occurrence of the highlighted word to the next and so on after each click.

问题 Actual page reference: www.friendsinclass.co.nf I'm building a simple chat, and I have one problem. The chat scrollbar auto-scrolls down when loading the page, as you can see in the updatescroll() function at the bottom. Currently, updatescroll is also called every second in setInterval within $(document).ready, in order to scroll down when a new message is written. As you can see, there is also a call to autoscroll() in submitChat(), which means autoscroll gets called everytime I SUBMIT a

问题 I'm having an issue combining PyQt4 scrollbars (on the MainWindow) with embedded scenes - everything works fine until I resize my window, after which my scenes begin to travel with the scrollbar off the page. Below is the simplified, full code to illustrate this behavior (with two screenshots attached afterward to explicitly showcase this interaction): import sys, os from pyface.qt import QtGui, QtCore os.environ['ETS_TOOLKIT'] = 'qt4' from traits.api import HasTraits,Instance,on_trait_change

问题 Currently, I am implementing a scrollbar using a custom embedded image using my CSS stylesheet. This is a very simple, thin scrollbar. I would like to configure this scrollbar using CSS properties at runtime, but so far I have been unable to do so. I know it can be done because I've seen examples of it in the net, but no code to review. Anyone have any suggestions? Thanks! 回答1: This blog has an example that you can view the source of with a right click: http://www.axelscript.com/2008/02/20

问题 Is there an easy way to attach a UI Slider to the side of a div to act as its' scrollbar? I don't care if it's technically on the side of the div or technically inside. I just need the UI Slider to look like the div's scrollbar. It'll be a fake scrollbar because the div's content will be dynamic, so I can't go the jScrollPane route. The content is populated based upon the values in the UI Slider. I'm stuck in CSS hell and was wondering if there's a few-line solution. Many thanks in advance!
