由 三世轮回 提交于 2019-12-04 15:24:44
问题 I have two divs like this <div style="border:1px solid #000; float:left">Div 1</div> <div style="border:1px solid red; float:left">Div 2</div> I want them to display on the same row, so I used float:left .

Can´t center textview´s text vertically

由 僤鯓⒐⒋嵵緔 提交于 2019-12-04 12:08:45
问题 [Solved] I had to add android:fillViewport="true" to the ScrollView, that fixed the problem with the text not centering vertically. I know this has been answered many times before, but I´m still not able to center a textview´s text vertically. <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/scrollView" android:layout_width="match_parent" android:layout_height="match_parent"> <RelativeLayout android:id="@+id/relativelayout" android:layout_width="match

Centering and aligning width of figcaption tag on image in figure tag

由 风流意气都作罢 提交于 2019-12-04 11:20:42
问题 I've spent two days now attempting to resolve a fig/figcation issue to no avail. I have a Django application where users are able to submit images and I'm using the figure and figcaption tags to display the image with an accompanying caption. The main issue is that the caption width exceeds the picture width. I'm trying to figure out a way for the image to remain the same size and the caption to line up in width accordingly. I'm using Twitter-Bootstrap as well. I'm open to all solutions. Any

Algorithm for finding a point in an irregular polygon

由 房东的猫 提交于 2019-12-04 09:28:12
问题 Imagagine I have a polygon like the following: I am looking for a C# algorithm with whom I can find a point (could be the middlepoint or also a random point) inside any polygon. For finding the center of mass I used the following algorithm: private Point3d GetPolyLineCentroid(DBObject pObject, double pImageWidth, double pImageHeight) { Point2d[] pointArray = GetPointArrayOfRoomPolygon(pObject); double centroidX = 0.0; double centroidY = 0.0; double signedArea = 0.0; double x0 = 0.0; //

由 走远了吗. 提交于 2019-12-04 05:56:37
I am working on code to find the points on the circumference of a circle . I have the center point of the circle and the radius and I need to draw a circle around it. This will help me define the boundary. Please help me with formula for finding the these points on the circumference. user_CC For a circle with origin (j, k) and radius r : x(t) = r cos(t) + j y(t) = r sin(t) + k where you need to run this equation for t taking values within the range from 0 to 360, then you will get your x and y each on the boundary of the circle.

How to figure out on which screen a JDialog is shown

由 ぐ巨炮叔叔 提交于 2019-12-04 04:57:51
I have a really big application which has multiple dialogs. My task is to make sure that a dialog, which is not completely visible (because the user pulled it out of the visible screen area) is moved back to the center of the screen. That's no problem when I'm dealing with one screen only. It works just fine ... however, most users of this application have two screens on their desktop ... When I try to figure out on which screen the dialog is shown and center it on that specific screen, ... well, it actually DOES center, but on the primary screen (which may not be the screen the dialog is

How can I get the current zoom level in a UIScrollView?

由 混江龙づ霸主 提交于 2019-12-04 04:32:19
In an attempt to create a workaround for centering an image in a UIScrollView and make it behave as Apple's Photos app does, I need to get the current zoom level and use the number to calculate the amount the image should be inset at each zoom level. (Note: I am aware that some programmers are centering an image in a scrollview by centering the image in a UIView that is the same size as the scrollview. This does not give good results and I am trying to find out how apple made it work in the photos app.) So, anyone know how to get the current zoom level of the content in a UIScrollView? In OS 3

dynamically center div over another div

由 旧巷老猫 提交于 2019-12-04 03:29:04
I'm looking to center a div without a fixed width over a video so if the window is resized, the div will shrink along with it but remain in the center. The current set up I have is close to correct using the left:50% with half negative margin. The issue is obviously that it moves left as the negative margin is fixed. Any ideas? Thanks! My HTML: <div id = 'top-container'> <video id='top-vid' autoplay loop width=100% height='auto' class='no-mobile'> <source src='DS_Intro.mov' type='video/mp4'> <source src='test.webm' type='video/webm'> </video> <div id = 'top-content'> <div id = 'top-text'> <div
