Why is the Visible property not correctly updated in a UserControl?

爱⌒轻易说出口 提交于 2019-12-01 06:24:01
Sometimes my UserControl's Visible property does not get updated correctly. It happens at my app's boot time, in OnFontChanged, fired from inside InitializeComponent, probably because some other stuff has not been set up yet. I just can't find out what. vScrollBar is a UserControl and is inside another UserControl. Apparently, this only happens when trying to set the value to true. vScrollBar already has its handle created, as a watch on IsHandleCreated says it's true. It may still show false if the Form has not loaded. Try setting it in the Form's OnLoad event. Reading the Visible property

I am really confused by the different properties that exist in JavaScript for getting the dimensions of a document and how to get those numbers. Can someone recommend a good place to start to understand how I would get the size of the document and position stuff correctly? dkugappi I'll try to answer as simply as I can. The Document and Viewport In terms of geometry, there are two sets of dimensions to be aware of; the document dimensions, which reflect the entire size of the loaded page, including the content beyond the bottom of the window and the viewport dimensions, which reflect the size

问题 Does anyone know of any documentation on the android:scrollbarStyle? I'd like to see examples of each of the 4 values w/ screenshots if possible. I see the difference between outside & inside types, but what are the Inset & Outset parts all about? I dont seem to see a difference between insideOutset & insideInset for example, likewise, I don't see a difference between outsideOutset & outsideOutset. thanks in advance! Ben 回答1: There are no values like outsideOutset and insideOutset. Possible

Is there any way to enable scrollbars for RecyclerView in code?

跟風遠走 提交于 2019-11-29 20:47:31
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 is: mRecyclerView.setVerticalScrollBarEnabled(true); and then I saw this in Android's document. So I

CSS 100% width on browser resize

喜欢而已 提交于 2019-11-29 14:02:10
Hi all I'm trying to build a layout using CSS and I'm coming up against a strange problem. Well strange for me. I have 3 divs a Header , a Footer and a MainContent area. Header and Footer must remain at a constant width of 100% while the MainContent area must be fixed centrally at 996px; This is all fine however when I resize the browser window to a width lower than 996px and then scroll the content of the window right the 100% header and footer seem to be truncated and are no longer 100%. I've knocked up a little bare-bones script to illustrate the issue (styles inline to keep it compact). I
