scrollbar

问题 I was hoping to collapse certain ListBoxItems based on a property of their data context. I came up with the following (trimmed for brevity) <ListBox ItemsSource="{Binding SourceColumns}"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Style.Triggers> <DataTrigger Binding="{Binding IsDeleted}" Value="True"> <Setter Property="Visibility" Value="Collapsed"/> </DataTrigger> </Style.Triggers> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate>

问题 When I run the app, the vertical scroll bar works as expected. However, when I add a new line/row, the bar (control that should go up and down on the slider) doesn't slide. With the mouse wheel I can scroll up and down the list of rows, and I can click on the up and down arrows. So the scroll bar works, but not as expected. The control should slide up and down, like it does at first, but after adding that new line, it does not. I hope that is clear enough, I've searched many issues to find

问题 Introduction: My Python Tkinter application is designed to have a scrollbar on the side so that if the window is resized, the application can still be viewed via the scrollbar. I do this by putting a frame with all my content inside a canvas, with a scrollbar controlling the canvas. On window resize, I have a function called resizeCanvas which resizes the canvas. Problem: After I resize the window, the scrollbar sort of works but it seems to jump around and fidget like its having a seizure.

问题 Here's my site with the current webkit scrollbar: http://willwhitehead.com I'd like to create a gap between the scrollbar and the right edge of the screen. How do I achieve this?

If you use a transparent border as a margin and a box-shadow with inset to set it's color, you'd get the result you are hoping for.

问题 I'm creating a banner at the top of my page. It's built using 3 banners that will have content.

问题 I'm using datatables.net library. There is a gap between table header and the table body, if I add scrollbar. Is there any way to remove it?
