overlap

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 work. The second thing I've tried is using JLayeredPanes. I can't seem to figure that one out either,

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.beginTransaction(); fragTrans.remove(currentFragment); FragmentB newFragment = new FragmentB(); fragTrans

So I've been working on this for the past week. Although it can't do miracles, I can say I've got a pretty good result: I just wanted to put this code out there for all the poor souls like me that are looking for some kind of vba macro that helps them avoid label overlaps in a scatter plot, because while doing my research on the subject, I wasn't able to find anything helpful. Const PIXEL_TO_POINT_RATIO As Double = 0.72 '1 Pixel = 72/96*1 Point Const tStep As Double = 0.1 Const rStep As Double = 0.1 Dim pCount As Integer Sub ExampleMain() RearrangeScatterLabels Sheet5 RearrangeScatterLabels

I am searching for an algorithm that will determine if a new rectangle is completely covered by a set of existing rectangles. Another way of putting the question, is does the new rectangle exist completely with the area covered by the existing rectangles? There seem to be lots of algorithms to determine rectangle overlap and so on, but I can't really find anything that solves this exact problem. The rectangles will be represented using x, y coordinates. This problem relates to geographical mapping. Edit - from comment posted by the OP: The rectangles are aligned on the X/Y axis If rectangles

Are there any good (if possible scientific) resources available (web or books) about overlap processing. I am not that interested in the effects of using overlap processing and windows when analyzing a signal, since the requirements are different. It is more about the following Real Time situation: (I am currently dealing with audio signals) Dividing a signal into smaller parts. Creating overlap windows. FFTing the windowed chunks. Do processing in the frequency domain. IFFT the results. put the chunks together to a continuous stream. I am especially interested in the influence of the window

im new in android im creating an app and i have a problem with a listfragment, because the list its showing but its overlapping the title bar(i had to add margin top to change that), and also im using a drawer and when im trying to open the list it shows over the options drawer too, letme paste you the code and the image so you can understan more: The xml code: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:weightSum="1
