scrollbar

问题 Say I have an appropriately sized image inside an Image() I want to change the Thumb or Knob of the JScrollBar component to be this image. I know I need to subclass the ScrollBarUI Here is where I am at right now. public class aScrollBar extends JScrollBar { public aScrollBar(Image img) { super(); this.setUI(new ScrollBarCustomUI(img)); } public class ScrollBarCustomUI extends BasicScrollBarUI { private final Image image; public ScrollBarCustomUI(Image img) { this.image = img; } @Override

问题 I was pulling my hair out for about 30 minutes trying to figure out why my webpage was shifting a few pixels when I was navigating between pages. I finally realized that it was because the right scroll bar, on the longer pages, was popping up and shifting stuff over. I found a solution that goes as follows. body{ overflow: scroll; } This forces every page to have a scroll bar, so the appearance/disappearance of the scroll bar does not jostle the elements of the page back and forth a few

问题 Firstly, I am no Javascript expert. I'd like to add a feature to a SELECT box I am using which automatically scrolls to the end when a new item is added, but only if the user has not scrolled up. Basically, when a user is reviewing older entries, I don't want new arrivals to snap the position to the end of the select list. However, if the user scrolls down to the bottom using the scroll bar, new arrivals shoudl automatically be brought into view. Here is what I have so far <script type="text

问题 Using leafletjs with popups. When I have popups with minimal text all works fine. If I make them bigger they still work fine. If I add too much I add maxHeight to the pop up and it makes the pop up scrollable. If I start with out enough content to fill the page and make it scrollable, it is not made scrollable. That is Ok till I dynamically add more content to the popup and then I need the scroll bar but it will not show up. Any thoughts on how to get leafletjs to add the scroll bar to a

问题 So after hours or reading post and looking at the documentation for tkinter I have found that on windows machines the color options for tkinter scrollbar will not work due to the scrollbar getting its theme from windows directly. My problem is the color of the default theme really clashes with my program and I am trying to find a solution that does not involve importing a different GUI package such as PyQt (I don't have access to pip at work so this is a problem to get new packages) Aside

问题 I'm loading a cross-domain page (that I have no control over) into an iframe. I want to know if this results in a scrollbar appearing in the iframe on my page or not. I'm getting the impression that this just cannot be done (in Firefox at least), through any kind of direct detection or clever deduction, due to cross-domain security policies. Please only answer this question if you have direct experience successfully doing this yourself -- or trying everything and giving up. (Those other

问题 Ok, here is my scrollbar style. <Style x:Key="{x:Type ScrollBar}" TargetType="{x:Type ScrollBar}"> <Setter Property="Background" Value="#D5E0FF" /> </Style> If I apply this, all scrollbars in my application will get affected, undoubtedly. Now I have 2 listview(s) in my application, I need to apply this style to only a particular listview, while another one remain default scrollbar, any idea? This is driving me crazy. Thanks. 回答1: Add the style as a resource to the ListView itself. <ListView>

问题 I have a container (let's say a div ) with overflow: auto . The elements in it are scrolled exactly as expected, but the typical touch scrollbar doesn't appear.
