I have created Actionbar for my app with viewpager and it works properly. Now I want to draw some objects on each fragment. Can anyone suggest a good tutorial or sample code on how to draw on fragment. I can draw objects on my view when myclass extends Activity but I don't know what to do when it extends Fragment. I have tried this code till now but it does not work public class MoviesFragment extends Fragment { ImageView imageView; Bitmap bitmap; Bitmap bit; Canvas canvas; Paint paint; public class DrawView extends View { Paint paint = new Paint(); public DrawView(Context context) { super

In my application I have a line drawn from one table cell to another cell through jQuery SVG plugin. Following the steps of the blog post http://www.openstudio.fr/Library-for-simple-drawing-with.html I managed to add it. But at the same time I need to remove that line and draw it on another place when mouse hovers. Is there a method to remove the drawn line or should I follow a different methodology to hide it or remove it ? Any help is highly appreciated. According to the documentation the line function returns an svg <line> element, so you should be able to remove it using the standard DOM

Imagine we have two randomly selected points between 0 and 100 for both x and y. For example: (95,7), (35,6) Now using the simple pygame.draw.line() function we could easily draw a line between these points without any gaps. My question is, how could we find a list of all the coordinates in a single pixel thick line between the two points without any gaps in the line? Secondly, is this even possible? I am using this list of pixel for the crack maze algorithm that needs to "shoot" another pixel while regarding any blocking walls that may interfere with its path. http://www.astrolog.org/labyrnth

I was wondering if anyone knew of any algorithm to draw a line with specific thickness, based on Bresenham's line algorithm or any similar. On a second thought, I've been wondering about for each setPixel(x,y) I'd just draw a circle, e.g.: filledCircle(x,y,thickness); for every x,y but that would of course be very slow. I also tried to use dictionary but that would fill the memory in no time. Check the pixels I'm about to draw on if they have the same color, but that's also not efficient enough for large brushes. Perhaps I could somehow draw half circles depending on the angle? Any input would

So I'm trying to count the words of my text file however when I do get-content the array reads them letter by letter and so it doesn't let me compare them word by word. I hope you guys can help me out! Clear-Host #Functions function Get-Articles (){ foreach($Word in $poem){ if($Articles -contains $Word){ $Counter++ } } write-host "The number of Articles in your sentence: $counter" } #Variables $Counter = 0 $poem = $line $Articles = "a","an","the" #Logic $fileExists = Test-Path "text.txt" if($fileExists) { $poem = Get-Content "text.txt" } else { Write-Output "The file SamMcGee does not exist"

My question is pretty standard but can't find a solution of that. I have points=[x,y,z] and want to plot best fit line. I am using function given below (and Thanx Smith) % LS3DLINE.M Least-squares line in 3 dimensions. % % Version 1.0 % Last amended I M Smith 27 May 2002. % Created I M Smith 08 Mar 2002 % --------------------------------------------------------------------- % Input % X Array [x y z] where x = vector of x-coordinates, % y = vector of y-coordinates and z = vector of % z-coordinates. % Dimension: m x 3. % % Output % x0 Centroid of the data = point on the best-fit line. %

I am learning some GUI stuff on Java and I think Im missing something here. I have some components vertically listed using BoxLayout, such as some JButtons one above other. Now I want to separate them drawing a line between them. Do I have to use the Graphics library or is there some Swing way to separate the components with a line? Going straight to the question: How to draw a line to separate components (such as JButtons) and which is the recommended way of doing it? Thanks! trashgod JSeparator , shown here , is commonly used in this context. It works well with most layouts. Also, consider
