overlap

问题 I've two overlapping edges and don't know why: digraph G { graph [rankdir=LR, overlap=false]; subgraph cluster1 { d1; n1; } subgraph cluster2 { n2; d2; } n1 -> n2; n2 -> n1; d0 -> d1; d0 -> d2; } Is there any way to display both edges n1 -> n2 and n2 -> n1 separately? Removing the clusters is not an option but would help ... 回答1: Trial-and-error solution (don't ask me why this works...): digraph G { graph [rankdir=LR, overlap=false]; subgraph cluster1 { d1; n1; } subgraph cluster2 { n2; d2; }

问题 I am trying to make the playing cards in my game overlap such that only the first half of a card is seen and the other half is covered by the next playing card. The only card that should be completely visible will be the last/rightmost card. I have used the following code with both framelayout and relativelayout to no avail. can anyone offer some suggestions? public int shouldShow(int numberOfCards, int card, int id) { if(card == -1) hide(id); else { findViewById(id).setBackgroundDrawable

问题 how can I overlap images half on one another from layout XML file like this image. 回答1: Simply you can use RealtiveLayout and negative margins <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/activity_landing" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/screen_background"> <ImageView android:background="@color/black" android:id="@+id/img_background" android

问题 My app currently looks like below. Three Button s in a RelativeLayout , the middle button has negative margin left and right to overlap the other two buttons. Issue : When I click either the left or the right button, it gets to the foreground for a second and overlaps the middle button, which looks very ugly. <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center_horizontal"> <Button android:id="@+id/voices" android:layout_width

问题 In our application, a lot of markers are drawn in different locations and in certain cases at a certain zoom level, markers overlap each other. So when I click on the marker, I expect the top marker's onMarkerClick to be fired but instead it is fired for the last hidden marker i-e the last marker, with no markers behind it. What do you suggest I do? Also, I have no info windows , therefore I return true from onMarkerClick method. 回答1: I found the solution here: https://github.com/googlemaps

问题 I have three tables with differing genomic intervals. Here is an example: > a chr interval.start interval.end names 1 chr1 5 10 a 2 chr1 6 10 b 3 chr2 7 10 c 4 chr3 8 10 d > b chr interval.start interval.end names 1 chr1 6 15 e 2 chr1 7 15 f 3 chr1 8 15 g > c chr interval.start interval.end names 1 chr1 7 12 h 2 chr1 8 12 i 3 chr5 9 12 j 4 chr10 10 12 k 5 chr20 11 12 l I am trying to find the common intervals between all tables after converting info to GRanges.

问题 What is the difference between these two queries : select a.gid, sum(length(b.the_geom)) from polygons as a , roads as b where st_intersects(a.the_geom,b.the_geom) group by a.gid ; select a.gid, sum(length(b.the_geom)) from polygons as a , roads as b where st_overlaps(a.the_geom,b.the_geom) group by a.gid ; Where the first query is giving the correct output whereas the second query retrieves no rows at all. The road that intersects the polygons also overlaps it, right? 回答1: From the

问题 I'm creating a virtual piano type program in Java Swing. My area for the piano keys right now is a JPanel with a horizontal BoxLayout containing white JButtons as white keys. I want to add black keys as well, and have them overlap the white keys. There are two different approaches I've tried. One is using the OverlayLayout. Unfortunately there isn't much documentation online for the OverlayLayout manager, and it's not available in the NetBeans GUI builder. I don't have a clue how to make it

问题 My requirement is quite simple: I have a button that should replace a FragmentA by FragmentB. This sounds easy and nearly work, the big problem is that the old fragment is not removed and the new placed on the front of the old one and they are "living" together in my layout. The Code: FragmentManager fragMgr = a.getSupportFragmentManager(); Fragment currentFragment = (Fragment) fragMgr.findFragmentById(R.id.fragmentitself); if(currentFragment!=null){ FragmentTransaction fragTrans = fragMgr
