  • Window colors/shades/decoarations/whatever per instance

    - by user35186
    Sometimes I open several instances of one program at the same time and have to switch between them every few seconds and get totally confused as to which is which (they all display similar information, except few bits). I'd like to have each one of them color-coded, different shades, window border, etc or have anything visual to make them differ from one another to ease the confusion. Ideally this would happen automatically when I launch a new instance. I guess this belongs to the window manager so mine is xfce. In one of the window managers I used to use a huge label was displayed each time I switched between workspaces, something like that (with window title or simple number) would do as well. Any clues?

  • Increase launcher and applet spacing on the Gnome Classic panel

    - by whtyger
    I'm using Ubuntu 12.04.1 with Gnome Classic. I added some launchers on the top panel, but they are placed too tightly (also take a look at separators, they aren't really separate anything): My Gnome Panel image Can I increase the spacing between the launchers? AFAIK this can be done by the editing of ~/.config/gtk-3.0/gtk.css. I've managed to toggle bold font setting for the panel this way. But I haven't found which parameter have an influence on the launcher and applet spacing. Also the size of icons seems too big for me - they occupy all place from the top to the bottom of the panel, without any border. They were smaller when I was using 10.04. Is there any way to reduce their size also?

  • How full is too full for mechanical hard drives?

    - by Sunny Molini
    I have heard many claim that it doesn't matter how full a drive is until it starts cutting into temp and virtual memory space. This doesn't make sense to me, given the nature of how the data is transacted on a hard drive. The inside of the platter presents less data per revolution than the outside of the drive does, by significant factors. The inside 40% of the radius of full size hard drive is used for the spindle, so only the outside 60% is used for data storage, but that still means that the inside track of a hard drive presents data 60% slower than the outside track. By my calculation, a Hard drive that is only 10% full should perform about 2.25 times faster than a hard drive that is 90% full, assuming that the flow is constrained by other factors. Am I wildly off base here? For all the drives I know, even the top speeds of the first 1% of the drive would be well within the bandwidth provided by a SATA 2 connection.

  • Catalyst forgets monitor settings after reboot or log out in 12.10

    - by Mate Weisz
    I have a Samsung monitor connected to my ATI Radeon graphic card via HDMI. By default the screen has a black border around, but I can disable it in the Catalyst menu to get full screen. (There is a scalebar that I have to set to the highest value.) My problem is that every time I turn off and on my computer it changes back and I have to set it up again. It is really annoying. Is there any way to make this setting permanent? Notes: 1. I open Catalyst with admin rights. 2. When I open the Catalyst settings menu, it looks like that it keeps my settings, because the scalebar stays at the highest point, but still it doesn't scale up my screen until I move back and forth the scale bar to the same point

  • Styling ASP.NET MVC Error Messages

    - by MightyZot
    Originally posted on: http://geekswithblogs.net/MightyZot/archive/2013/11/11/styling-asp.net-mvc-error-messages.aspxOff the cuff, it may look like you’re stuck with the presentation of your error messages (model errors) in ASP.NET MVC. That’s not the case, though. You actually have quite a number of options with regard to styling those boogers. Like many of the helpers in MVC, the Html.ValidationMessageFor helper has multiple prototypes. One of those prototypes lets you pass a dictionary, or anonymous object, representing attribute values for the resulting markup. @Html.ValidationMessageFor( m => Model.Whatever, null, new { @class = “my-error” }) By passing the htmlAttributes parameter, which is the last parameter in the call to the prototype of Html.ValidationMessageFor shown above, I can style the resulting markup by associating styles to the my-error css class.  When you run your MVC project and view the source, you’ll notice that MVC adds the class field-validation-valid or field-validation-error to a span created by the helper. You could actually just style those classes instead of adding your own…it’s really up to you. Now, what if you wanted to move that error message around? Maybe you want to put that error message in a box or a callout. How do you do that? When I first started using MVC, it didn’t occur to me that the Html.ValidationMessageFor helper just spits out a little bit of markup. I wanted to put the error messages in boxes with white backgrounds, our site originally had a black background, and show a little nib on the side to make them look like callouts or conversation bubbles. Not realizing how much freedom there is in the styling and markup, and after reading someone else’s post, I created my own version of the ValidationMessageFor helper that took out the span and replaced it with divs. I styled the divs to produce the effect of a popup box and had a lot of trouble with sizing and such. That’s a really silly and unnecessary way to solve this problem. If you want to move your error messages around, all you have to do is move the helper. MVC doesn’t appear to care where you put it, which makes total sense when you think about it. Html.ValidationMessageFor is just spitting out a little markup using a little bit of reflection on the name you’re passing it. All you’ve got to do to style it the way you want it is to put it in whatever markup you desire. Take a look at this, for example… <div class=”my-anchor”>@Html.ValidationMessageFor( m => Model.Whatever )</div> @Html.TextBoxFor(m => Model.Whatever) Now, given that bit of HTML, consider the following CSS… <style> .my-anchor { position:relative; } .field-validation-error {    background-color:white;    border-radius:4px;    border: solid 1px #333;    display: block;    position: absolute;    top:0; right:0; left:0;    text-align:right; } </style> The my-anchor class establishes an anchor for the absolutely positioned error message. Now you can move the error message wherever you want it relative to the anchor. Using css3, there are some other tricks. For example, you can use the :not(:empty) selector to select the span and apply styles based upon whether or not the span has text in it. Keep it simple, though. Moving your elements around using absolute positioning may cause you issues on devices with screens smaller than your standard laptop or PC. While looking for something else recently, I saw someone asking how to style the output for Html.ValidationSummary.  Html.ValidationSummery is the helper that will spit out a list of property errors, general model errors, or both. Html.ValidationSummary spits out fairly simple markup as well, so you can use the techniques described above with it also. The resulting markup is a <ul><li></li></ul> unordered list of error messages that carries the class validation-summary-errors In the forum question, the user was asking how to hide the error summary when there are no errors. Their errors were in a red box and they didn’t want to show an empty red box when there aren’t any errors. Obviously, you can use the css3 selectors to apply different styles to the list when it’s empty and when it’s not empty; however, that’s not support in all browsers. Well, it just so happens that the unordered list carries the style validation-summary-valid when the list is empty. While the div rendered by the Html.ValidationSummary helper renders a visible div, containing one invisible listitem, you can always just style the whole div with “display:none” when the validation-summary-valid class is applied and make it visible when the validation-summary-errors class is applied. Or, if you don’t like that solution, which I like quite well, you can also check the model state for errors with something like this… int errors = ViewData.ModelState.Sum(ms => ms.Value.Errors.Count); That’ll give you a count of the errors that have been added to ModelState. You can check that and conditionally include markup in your page if you want to. The choice is yours. Obviously, doing most everything you can with styles increases the flexibility of the presentation of your solution, so I recommend going that route when you can. That picture of the fat guy jumping has nothing to do with the article. That’s just a picture of me on the roof and I thought it was funny. Doesn’t every post need a picture?

  • -webkit-linear-gradient Not working in Dreamweaver CS6

    - by Ken
    I've tried multiple times to apply the following piece of code in a CSS document: display: block; width: 500px; margin: 500px auto; padding: 15px; text-align: center; border: 4px solid blue; background: -webkit-linear-gradient(top,black,white); outline: 7px solid red; Everything appears correctly, except the gradient. I have CS6 Live View turned on, and it still refuses to appear. All I get in my box is a white background, as opposed to the black to white gradient. However, when I type the same line of code into the trial of Coda 2 I downloaded, it works perfectly. Is there anything I can do to resolve the issue?

  • How do you explain ethernet cable problems to non networking people?

    - by Bryan McLemore
    We've recently been doing a large network migration in our datacenter. We've had a few cables in this start to deliver really bad pings (in excess of 500ms on a LAN) before they could be replaced. The cables we were replacing weren't made the best. They where all hand made and the runs were so short on some of them that the bend radius was definitely too tight. Some of them ran in bundles right in front of the heat exhaust of the power supplies. The cables were running ok until we started pulling the ones surrounding them out. Then a few started having the problem I mentioned above degrading performance and causing reliability issues. I'm trying to figure out the best way to explain this to non networking people. Is there any documentation that people could recommend or other methods?

  • I have an "amoeba" game mechanic. Any idea on how to implement it?

    - by Jason
    Outside of a tetris clone, a crappy 2D top-down shooter, and some messing around with stuff like Unity and Flixel, I realize that I have yet to complete a single, polished, bells-and-whistles game. I want to change this, and I have an idea for my next project. The idea is that you're an amoeba. Amoebas have these eye-like cores (or something like that, I don't know biology), and you have two of 'em. You control one with WASD and the other with IJKL. There has to be a constant radius of stuff around each of the cores: And the area of the amoeba has to stay constant. So if you move a core in one direction, you increase the amoeba's area, but that increase is compensated by a decrease somewhere else: Aaaaaand I'd like to implement a vagination mechanic. You absorb things by engulfing them, like a boss. Maybe even an extra core, or a needle that pops you and causes all your inner stuff to start gushing out: But here's the problem: I don't know how to make this. However, I would like some ideas on how to implement it. Should I explore physics libraries like Box2D? Or maybe something involving fluid physics? Any help would be much appreciated. P.S. Feel free to steal this idea. I have plenty of ideas. If you do, please tell me how you made it so I can try it myself.

  • What would be a good opensource software for graphing circles, circular regions, and regions bounded by curves and/or arcs?

    - by Michael Dykes
    Hullo all. I have just started s job with Chegg, and my 1st assignment has me writign solutions for Stewart's Essential Calculus. I am dealing with the chapter on multiple integration, and need a good open-source software that I can easily use to draw regions (domains) that would require multiple integrals: i.e. circular regions, portions of circles, regions bounded by curves and/or arcs, and at some point 3D pictures. In most of these cases, I am not working with an exact equation or perhaps need to draw the region bounded by r (radius) between 1 and 2, and the angle theta bounded between pi/4 and 3 pi/4. I am not too terribly familiar with programs like Corel Draw, but the documents I have from this company suggest Corel Draw. So I think I am looking for an open-source free program like Corel Draw or something similar. Any additional suggestions would also be appreciated. I know I can do most, if not all of this using TikZ, but the learning curve is a bit steep, and at the moment I an on a time constraint. Thanks.

  • Connecting to Aerohive AP's from Laptops running Win. 7 using authentication from a Windows 2008 domain server

    - by user264116
    I have deployed a wireless network using Aerohive access points. 2 of them are set up as radius servers. I want my users to be able to use the same user name and password they use when they log onto our domain. They are able to do this from android devices or computers running Windows 8. It will not work on Windows 7 machines. How do I remedy this situation, keeping in mind that the machines are personal machines not company owned and I will have no way to change their hardware or software.

  • What is causing this behavior with the movement of Pong Ball in 2D? [closed]

    - by thegermanpole
    //edit after running it through the debugger it turned out i had the display function set to x,x...TIL how to use a debugger I've been trying to teach myself C++ SDL with the lazyfoo tutorial and seem to have run into a roadblock. The code below is the movement function of my Dot class, which controls the ball. The ball seems to ignore yvel and moves with xvel to the bottom right. The code should be pretty readable, the rest of the relevant facts are: All variables are names Constants are in caps dotrad is the radius of my dot yvel and xvel are set to 5 in the constructor The dot is created at x and y equal to 100 When I comment out the x movement block it doesn't move, but if i comment out the y movement block, it keeps on going down to the right. void Dot::move() { if(((y+yvel+dotrad) <= SCREEN_HEIGHT) && (0 <= (y-dotrad+yvel))) { y+=yvel; } else { yvel = -1*yvel; } if(((x+xvel+dotrad) <= SCREEN_WIDTH) && (0 <= (x-dotrad+xvel))) { x +=xvel; } else { xvel = -1*xvel; } }

  • Black frame around screen after HDMI connection failure

    - by Wolter Hellmund
    I was trying to watch a movie in my computer through the TV, so I connected both with an HDMI cable. I was unable to have a successful setup (the colors were all weird on the TV and the screen size, incorrect), I tried many resolutions using the nvidia-settings application and somehow my screen got framed by a black border and after that I have been unable to remove it, even after restarting the computer and not being connected to the HDMI cable anymore. I am using Ubuntu 11.10 amd64, my GPU is an nVidia GeForce 8600M GT and I am using the propietary driver version 280. The problem is due to some setting with my account only. I logged in to the guest session and the resolution is right there. Also, my desktop "thinks" the resolution is right (i.e. 1280x800), but it must be right in another scale because there is pixel area occupied by the black frame.

  • Cisco 2900 series router - 3x 3g HWIC - Can you use the same subnet for each HWIC?

    - by Lance
    We host a site with a 2900 series router with 3x 3G-HWIC cards installed. It is hosted with telstra and plugs into our corporate WAN. The card authenticates against radius and advertises a route into the WAN for which subnet it routes for. We have always used the same advertised subnet on each. Telstra have advised us that this could be the cause of some drop out issues whereby some services will work for some people and not for others and are saying effectively that their system will only use one of these at a time even though we can see the interface is online and assigned a WAN IP address. Has anyone out there configured a multi HWIC setup before and if so are they using different subnets for each or the same?

  • screen flickering

    When using some applications (LibreOffice, Chrome) it happens that screen flicker (just for a second, or even less than a second) or screen turns into black and then back to normal again... it all happens very fast (usually when clicking with the mouse)... for example, I was searching something in google chrome and list of possible results appeared - when I double click on the search text area (not list of possible results) screen flicker... or when changing border lines in LibreOffice Calc... I managed to create screen shot while using LibreOffice Calc. I am using Nvidia 313 drivers-updates on Ubuntu 13.04. What could be the problem?

  • Why doesn't my Nvidia driver support 1280*1024?

    - by Alvar
    EDIT: I think the problem is in the NVIDIA x server, that doesn't support an RGB screen from 1990. The screen was the best of them all when it was released. This a strange thing! In windows the EDID must work because 1280*1024 is used as max resolution, but in ubuntu those stuff aren't being received, so how do I tell ubuntu/nivida to find those EDID stuff? Hi, I have an external monitor which is an 20" 1280*1024. In windows 7 it works fine with that resolution but in ubuntu it can't. The screens model name is IntelliColor Display/20 and the name of the company is "radius".recived Well, twin view is working but the only maximum resolution is 1024*768. I'm using nividas x server program. If I force it to use 1280*1024 it all crashes and I have to force a reboot. alvar@alvars-laptop:~$ disper -l display DFP-0: HSD121PHW1 resolutions: 320x175, 320x200, 360x200, 320x240, 400x300, 416x312, 512x384, 640x350, 576x432, 640x400, 680x384, 720x400, 640x480, 720x450, 640x512, 700x525, 800x512, 840x525, 800x600, 960x540, 832x624, 1024x768, 1366x768 display CRT-0: CRT-0 resolutions: 320x240, 400x300, 512x384, 680x384, 640x480, 800x600, 1024x768, 1152x864, 1360x768

  • How to offset particles from point of origin

    - by Sun
    Hi I'm having troubles off setting particles from a point of origin. I want my particles to spread out after a certain radius from a the point of origin. For example, this is what I have right now: All particles emitted from a point of origin. What I want is this: Particles are offset from the point of origin by some amount, i.e after the circle. What is the best way to achieve this? At the moment, I have the point of origin, the position of each particle and its rotation angle. Sorry for the poor illustrations. Edit: I was mistaken, when a particle is created, I have only the point of origin. When the particle is created I am able to calculate the rotation of the particle in the update method after it has moved to a new location using atan2() method. This is how I create/manage particles: Created new particle at enemy ship death location, for every new particle which is added to the list, call Update and Draw to update its position, calculate new angle and draw it.

  • How to "paint" the data layer of a CD using a CD drive?

    - by Jens
    I am looking for software to "paint" geometric shapes, dots or lines on the data layer of a writable CD (or DVD) using a standard drive. These do not have to be visible to the naked eye; I'd try to abuse the small dot size on the CD for some scientific measurements. I am aware of the "LightScribe" feature of some drives and that is not what I am looking for. Most of the software available is of course limited to write music or data, on does not offer the low-level "place a dot at this radius, this angle"-functionality. Is there something out there for me?

    Hello, We currently utilize wifi access in some of our buildings, we are not using RADIUS at this point, but we are using WPA2 with PKI, the issue has recently come up that we want to keep our key private so we generally setup access for our users providing them the wifi key. The problem is that windows seems to give the option to go back into the wireless properties and unmask the PSK. We need to resolve this ASAP is there a way to make certain that the PSK remains masked regardless even if your logged in as a local administrator to the machine? Thanks in advance.

  • How do I configure the mouse to raise and lower windows

    - by user288496
    I've just installed 14.04 and cannot find the congfuration screen to control how mouse clicks are acted on by the window manager, and then optionally passed to the application. I want to set the sane traditional unix behaviour of: - 'focus follows mouse': done. - 'never auto-raise': done. - 'raise when click on border or title': Can't find the option. A middle button click on the tile does lower a window - but traditionally it would also raise the botton window. I can set 'raise on any click' - but that is absolutely hopeless when you are trying to copy text from a lower window.

    Hi guys i am stuck with filling up the data of all the blocks which are empty like the ones in the image. As you can see there i have a pacman like object where i will be moving around. But when you are in the empty space where there are no Blue boxes available i should be able to add new blocks in the path of my pacman and when it touches any other blue boxes like in the below case if my pacman touches the top row of the blue box i should be able to fill all the empty boxed inside the border of the path created by pacman. For now i am using a 2d bool array to store all the filled boxed info like if there is a box inside i am making that cell in an array as true. But how to fill the area with blue boxes after player finishes his path ? Any help would be great thank you. More info about this problem is here: filling the empty spaces in a certain region in a grid using c++ Same problem

  • Web-Service: How much would you charge? [closed]

    - by jacksbox
    I´ve to make an offer to a client who wants me to develope a web-service for him. I have some trouble calculating the pricing - can you help me? Here is a rough outline of the project: It´s a portal on which various artists and entertainers can register and administrate there profile (texts, gallerie, some embedded videos, choose categories and radius of offer, etc). Other user can browse the artists by 3-4 level categories and countries/staats. If someone wants to hire a artists, he can put them in an "shopping-basket" and can mail everyone in his basket. The Artists can answer them with a form on the website (he doesn't get the email of the other person). Users should be able to comment/rate the artists. But if an artists wants this comments/ratings visible on his profile he must pay, and after that, the admin of the site must activate this comments/ratings. So, no more information given, what would you charge (ca.)? Edit: It´ll be developed with php/codeigniter. A .psd design is already there.

  • Parsing GeoRSS Feed with jQuery

    - by senfo
    I'm attempting to use the jQuery jFeed plugin for parsing an Atom, GeoRSS feed and I'm running into issues extracting the information I need. For example, I need to extract the summary element and I would like to render the contents in a div on my HTML page. Additionally, I'd like to extract the contents from the georss:point elements and pass them into Google Maps to render them as points on a map. The problem is that it seems jFeed is stripping out the GeoRSS-related information. For example, I can extract the title element without issues, but it seems it doesn't extract the summary or georss:point elements, at all. Following is a snippet of the XML I'm working with: <feed xmlns="http://www.w3.org/2005/Atom" xmlns:georss="http://www.georss.org/georss"> <title>Search Results from DataWarehouse.HRSA.gov</title> <link rel="self" href="http://datawarehouse.hrsa.gov/HGDWDataWebService/HGDWDataService.aspx?service=HC&zip=20002&radius=10"/> <link rel="alternate" href="http://datawarehouse.hrsa.gov/"/> <author> <name>HRSA Geospatial Data Warehouse</name> </author> <id>tag:datawarehouse.hrsa.gov,2010-04-05:/</id> <updated>2010-04-05T19:25:28-05:00</updated> <entry> <title>Christ House</title> <link href="http://www.christhouse.org" /> <id>tag:datawarehouse.hrsa.gov,2010-04-05:/D388C4C6-FFA4-4091-819B-64D67DC64931</id> <summary type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml"> <div class="vcard"> <div class="fn org">Christ House</div> <div class="adr"> <div class="street-address">1717 Columbia Rd.

  • Android refresh StateListDrawable problem

    Hi all, I have a strange problem with StateListDrawable or maybe (probably) I'm missing something. I created a test application for it and the same problem occurs. So, this is my StateListDrawable resourse in file test_selection.xml <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_selected="true"> <shape android:shape="rectangle" android:background="#ff0000"> <corners android:radius="10dp" /> <gradient android:startColor="#ff5555" android:endColor="#ff5555" android:angle="0" /> </shape> </item> <item android:state_selected="false"> <shape android:shape="rectangle" android:background="#eeeeee"> <corners android:radius="10dp" /> <gradient android:startColor="#eeeeee" android:endColor="#eeeeee" android:angle="0" /> </shape> </item> </selector> It's a very simple selector that draw a red color for selected state and a white rect for the unselected one. My main.xml template is very simple. I simply use a TextView that uses the selection as background. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" android:textSize="30dp" android:id="@+id/test_view_example" android:background="@drawable/test_selection"/> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/refresh" android:onClick="updateView" android:text="refresh"></Button> </LinearLayout> My Activity code is also very simple. public class TestDrawableStateActivity extends Activity { private final static int[] SELECTED_STATE = { android.R.attr.state_selected }; private final static int[] UNSELECTED_STATE = {}; private TextView textView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.test_view_example); } @Override protected void onResume() { super.onResume(); // Carichiamo la Drawable if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); } } public void updateView(View view) { if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); }; } } When Activity starts I try to set the state of my Drawable (the StateListDrawable) with the value SELECTED. It seems all very simple.... but the problem is that the state is not shown. If, later, I click a button and execute the method updateView() the state changes. Where is my problem? Where am I wrong? Thankx a lot Max

  • Draw Circle on the Map once the application gets loaded

    - by TechGeeky
    Background:- In my application what is happening currently- Whenever I am opening the application, In the top half of the android screen, it draws a Map and in the bottom half of the android screen it show's a list view. And then as soon as the location gets changed, it draw's a Circle with the current location as the center of the circle and show's an image at the current location(center of circle). Everything is working fine till here- Problem Statement:- What I want is when the user opens my application, circle should get draw immediately on the Google Map (this is currently not happening, it draw's circle only on the location changed), without waiting for the location to get changed and without any image on the center of circle and then if the location get's changed, take the current location as the center of circle and draw the circle with an image at the center of circle. And this is my below code which fulfills the scenario that I mentioned in my Background- How can I make this code to work the way I wanted to? hope I am clear enough in my question. Any suggestions will be appreciated. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mapView = (MapView) findViewById(R.id.mapView); listView = (ListView) findViewById(R.id.mylist); locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationListener = new GPSLocationListener(mapView); locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 35000, 10, locationListener); mapView.setStreetView(true); mapView.setBuiltInZoomControls(true); mapController = mapView.getController(); mapController.setZoom(14); } Location Update class where I am sending the request to Overlay to draw the circle private class GPSLocationListener implements LocationListener { MapOverlay mapOverlay; public GPSLocationListener(MapView mapView) { } @Override public void onLocationChanged(Location location) { if (location != null) { GeoPoint point = new GeoPoint( (int) (location.getLatitude() * 1E6), (int) (location.getLongitude() * 1E6)); mapController.animateTo(point); mapController.setZoom(15); if (mapOverlay == null) { mapOverlay = new MapOverlay(this,android.R.drawable.star_on); List<Overlay> listOfOverlays = mapView.getOverlays(); listOfOverlays.add(mapOverlay); } mapOverlay.setPointToDraw(point); mapView.invalidate(); } } @Override public void onProviderDisabled(String provider) { } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } } Class in which circle is getting drawn. class MapOverlay extends Overlay { private GeoPoint pointToDraw; int[] imageNames=new int[6]; private Point mScreenPoints; private Bitmap mBitmap; private Paint mCirclePaint; public MapOverlay(GPSLocationListener gpsLocationListener, int currentUser) { imageNames[0]=currentUser; mCirclePaint = new Paint(Paint.ANTI_ALIAS_FLAG); mCirclePaint.setColor(0x30000000); mCirclePaint.setStyle(Style.FILL_AND_STROKE); mBitmap = BitmapFactory.decodeResource(getResources(),imageNames[0]); mScreenPoints = new Point(); } public void setPointToDraw(GeoPoint point) { pointToDraw = point; } public GeoPoint getPointToDraw() { return pointToDraw; } @Override public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { super.draw(canvas, mapView, shadow); if (pointToDraw == null) { return true; } mScreenPoints = mapView.getProjection().toPixels(pointToDraw, mScreenPoints); int totalCircle=5; int radius=40; int centerimagesize=35; for (int i = 1; i <= totalCircle; i ++) { canvas.drawCircle(mScreenPoints.x,mScreenPoints.y, i*radius, mCirclePaint); } canvas.drawBitmap(mBitmap, (mScreenPoints.x-(centerimagesize/2)),(mScreenPoints.y-(centerimagesize/2)), null); super.draw(canvas,mapView,shadow); return true; } }
