scrollbars

问题 As we saw, RecyclerView is more effective than ListView, so I prefer to use it in my project. But recently I have a trouble when put it in my custom ViewGroup. RecyclerView is easy to set scrollbars in xml like this: <android.support.v7.widget.RecyclerView android:id="@+id/recycler_view" android:scrollbars="vertical" android:layout_width="match_parent" android:layout_height="match_parent" /> But I really can't find any method to set the scrollbars in code for RecyclerView, what I have tried

问题 I have a Panel with scrollbars, and I frequently want to programmatically scroll a control into view. For reasons that don't bear mentioning I need my own methods. Frequently when I try to set MyPanel.HorizontalScroll.Value = newScrollValue; the value simply won't take . I can check MyPanel.HorizontalScroll.Value immediately after the set, and its value is unchanged. The values that I'm trying to set are definitely within the Minimum and Maximum range. Now here's the worst part. I found out

问题 I'm trying to get my DIV to display only a horizontal scrollbar. I am filling up the DIV with lots of images, and only want the user to be able to scrol horizontally. But I have two problems: One tutorial I read gave me some code (which I no longer have), that says it will display the scrollbar. But it didn't. And it also made the images appear beneath each other.

问题 I created a .PDF file using Adobe Acrobat Pro. The file has several text fields. Using iTextSharp, I'm able to populate all the fields and mail out the .PDF. One thing is bugging me - some of the next will not "fit" in the textbox. In Adobe, if I type more that the allocated height, the scroll bar kicks in - this happens when font size is NOT set to auto and multi-line is allowed. However, when I attempt to set the following properties: //qSize is float and set to 15; //auto size of font is

问题 The scrollbars in Lion seem to be based on the HTML's background color (lighter color BG = black scrollbars, darker BG = white). The problem I'm running into is from what (I assume) is a common trick regarding footers. I usually set the background color for my HTML element to be the footer's color, that way if the page is shorter than the browser window the footer appears to continue on (since the BODY element ends and then the HTML element is what shows until the end of the page).

问题 I am trying to create scrollbars in a window created by OpenCv python. I know that I need to implement the code to handle the scrolling/panning process but I have no idea where to start and I've looked everywhere. It is essential that I create the scrollbars in the OpenCV window instead of using some other GUI window framework. Below is the code I am using to load an image and scale the image(which works). Any help is appreciated. And please don't refer me to the opencv documentation on
