  • Can we identify individual sectors of a circle component uniquely in flex?

    - by Angeline Aarthi
    I have a custom circle component in my application, which is divided into 3 sectors as of now.Can we uniquely identify each segments of this circle? I want to drag and drop text or images from another container to this circle component. But I want to place different images in the different sectors. Is it possible to distinguish the individual sectors of the circle component? Here is my code: <mx:TabNavigator width="624" height="100%"> <mx:VBox id="currQuote" label="Currents Quote" width="100%"> <comp:MyCircle x1="175" y1="150" radius="150"/> <comp:MyCircle x1="175" y1="150" radius="120"/> <comp:MyCircle x1="175" y1="150" radius="25"/> <comp:MyLine x1="160" y1="122"/> </mx:VBox> <mx:VBox label="Quote Comparison" width="100%"/> <mx:VBox label="Reports" width="100%"/> </mx:TabNavigator> Circle component: package components { import mx.core.UIComponent; public class MyCircle extends UIComponent { public var x1:int; public var y1:int; public var radius:int; override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { graphics.lineStyle(1, 0x000000); graphics.drawCircle(x1, y1, radius); } } } Line component: package components { import mx.core.UIComponent; public class MyLine extends UIComponent { public var x1:int; public var y1:int; override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { graphics.lineStyle(1, 0x000000); graphics.moveTo(100,0); graphics.lineTo(x1, y1); graphics.moveTo(250,0); graphics.lineTo(185,120); } } } Actually I want the circle to be divided into 6 sectors, but for now just divided it into 3 sectors. But is it possible to uniqulely identify the individual sectors of the circle so that I can drag different images or texts into those particular sectors?

  • How to share internet connection on Mac os x to Virtualbox vm’s using Host-only

    - by redben
    In one line : is the following possible : Airport <- "osx bridge" - vbox-Host-only - vm's Virtualbox (3.1.4) setup : Host : Mac OS X 10.5 Guest : Ubuntu Linux adapter1 - Bridged (en1: Airport) : To give the vm access to internet and communicate when Airport is connected adapter2 - Host-Only (vboxnet0) : To enable host/guest communication when Airport is not connected I'd like to make it simpler and only keep adapter 2 (host-only) and relying on os x connection sharing/bridging I thought i could just keep the Host only configuration, and on the host go to internet sharing and select "share from airport" to vboxnet0 . Only to find out that vbox's virtual interface doesn't appear in the interfaces list on os x preferences. I know that on a linux host you could install something called bridge-utils and use that to bridge the two insterfaces. Is there any thing like that for Mac ?

  • Port forwarding using IP Tables

    - by Darider
    I have a server with a LAN facing address of 192.168.5.100 (eth0) and another LAN facing address of 192.168.6.6 (eth1). On this server I have a Virtualbox instance of fedora running an apache webserver (on port 8080) with a bridged interface to eth1 on the host server with address of 192.168.6.7 Users on the 192.168.6.x network can access the Webserver on the Vbox instance (192.168.6.7) with no problems. My question is what kind of iptables entries or commands should be made/executed so as to allow for users on the 192.168.5.x network to access the webserver on the vbox instance. (I'm hoping their url can be something like: http://192.168.5.100:8080)

    I have VirtualBox Portable installed from vbox.me. I moved it on a USB drive and added a virtual Ubuntu. It works fine on the computer I created it, but moving the usb drive to a different the Ubuntu does not start any more. I already changed location descriptions in <machine>.vbox and the VirtualBox.xml. When pressing Shift while starting the GRUB loader comes up, so I tried the recovery mode. Same here – startup freezes and nothing happens. Any hints for me?

  • Java Fx Data bind not working with File Read

    - by rjha94
    Hi I am using a very simple JavaFx client to upload files. I read the file in chunks of 1 MB (using Byte Buffer) and upload using multi part POST to a PHP script. I want to update the progress bar of my client to show progress after each chunk is uploaded. The calculations for upload progress look correct but the progress bar is not updated. I am using bind keyword. I am no JavaFx expert and I am hoping some one can point out my mistake.

  • pass data from popup to parent

    - by user522962
    I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that? Here's my parent: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" backgroundColor="green" width="50%" height="100%" xmlns:local="*" > <fx:Script> <![CDATA[ import pup; import mx.managers.PopUpManager; public function showPup(evt:MouseEvent):void { var ttlWndw:pup = PopUpManager.createPopUp(this, pup, true) as pup; PopUpManager.centerPopUp(ttlWndw); } ]]> </fx:Script> <mx:VBox> <local:pup id="pupLove" visible="false" includeInLayout="false" /> <s:Button click="showPup(event);" label="launch Pup" /> <mx:Text id="Ptest" color="black" text="from Parent:{pupLove.dg.length}" /> </mx:VBox> </s:Application> And a popup child called 'pup.mxml': <?xml version="1.0" encoding="utf-8"?> <s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"> <fx:Script> <![CDATA[ public function init():void{ // send php call } import mx.events.CloseEvent; import mx.managers.PopUpManager; private function removePup(evt:Event):void { PopUpManager.removePopUp(this); } ]]> </fx:Script> <fx:Declarations> <s:ArrayCollection id="dg"> </s:ArrayCollection> </fx:Declarations> <s:TitleWindow width="100%" height="100%" close="removePup(event)"> <mx:VBox> <mx:Text id="test" color="red" text="from Child:{dg.length}" /> <s:Button label="add Items" click="dg.addItem({id:'cat'})" /> </mx:VBox> </s:TitleWindow> </s:Group> UPDATE: I guess my question can be more easily stated as: "is there a way to call a child's function from the parent without actually loading the child?"

  • Seamless Mode Not Working Correctly in Virtual Box

    - by Jeremy
    I run Ubuntu Desktop in a VirtualBox seamless mode, hosted on Windows 7. I recently upgraded from 11.10 to 12.04 and seamless mode no longer works correctly. I have re-installed guest extensions. The problem is that the Ubuntu desktop wallpaper is shown, effectively blocking the Windows desktop. I can bring Windows apps to the foreground, but as soon as I bring any Ubuntu window to the foreground, all the windows apps will disappear, hidden by the ubuntu desktop even if I activated an Ubuntu window in a different monitor. So, it is not very much different from full-screen mode at this time. I suspect if I could turn off the Ubuntu desktop or wallpaper this would be a sufficient workaround (this is basically what Seamless mode is) but that does not seem to be possible within Ubuntu itself. [Jeremy doesn't specify system config, but I can confirm I'm seeing this behavior in Win 7 64-bit with both 32-bit and 64-bit guests. Giovanni sees the same thing on his laptop running Vista Ultimate 64 bit after upgrading his 32-bit guest to 12.04 (forums.virtualbox.org p225407, requires logging in with your free Oracle account). I was using vbox 4.1.14r77440 and matching Guest Additions. I upgraded to 4.1.16-78094 vbox+additions. Still a problem. And I filed launchpad bug 999929 to see if I can get feedback from developers. – tbc0] Any other ideas?

  • Unable to Install VirtualBox Due to Missing Kernel Module

    - by SoftTimur
    I am trying to install VirtualBox on my Ubuntu. I first tried to sudo apt-get install virtualbox-ose in a terminal, but after the configuration step, it fails with an error: No suitable module for running kernel found When proceeding with starting virtualbox, I get this error: WARNING: The character device /dev/vboxdrv does not exist. Please install the virtualbox-ose-dkms package and the appropriate headers, most likely linux-headers-generic. You will not be able to start VMs until this problem is fixed. So I tried the package from http://www.virtualbox.org/, but starting VirtualBox fails with: WARNING: The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (2.6.38-8-generic-pae) or it failed to load. Please recompile the kernel module and install it by sudo /etc/init.d/vboxdrv setup You will not be able to start VMs until this problem is fixed. So I ran sudo /etc/init.d/vboxdrv setup, but it fails too: * Stopping VirtualBox kernel modules [ OK ] * Uninstalling old VirtualBox DKMS kernel modules [ OK ] * Trying to register the VirtualBox kernel modules using DKMS Error! Your kernel headers for kernel 2.6.38-8-generic-pae cannot be found at /lib/modules/2.6.38-8-generic-pae/build or /lib/modules/2.6.38-8-generic-pae/source. * Failed, trying without DKMS * Recompiling VirtualBox kernel modules * Look at /var/log/vbox-install.log to find out what went wrong The contents of /var/log/vbox-install.log. As I am stuck, I also tried to install kernel-devel with yum, still fruitless: root@ubuntu# yum install kernel-devel Setting up Install Process No package kernel-devel available. Nothing to do Now I've no idea how to correct this. Any ideas?

    I have Dell vostro 3500 Laptop. I Installed Ubuntu 12.04. It doesn't detect my bluetooth. below is my information. lsusb | grep Bluetooth Bus 001 Device 003: ID 0a5c:4500 Broadcom Corp.

I saw other place (I don't remember which site) They said, some times, when in windows, if bluetooth disabled by windows driver, It can't be enabled by linux. So, I should install windows and enable blueethooth from windows and then re install linux. That is impossible for me, because I don't have Windows installation media. But I tried this, which is I installed windows xp on virtual box. Vbox showed me thow unknow USB devices. I connected them and installed windows bluethooth drivers to xp. But it didn't ditected Bluethooth either. Also, when I set off mode in hardware switch, those unknown devices disappear from Vbox usb device seletcion menu. So, they are definitely something to do with wifi or bluethooth. Please help me..

  • How to set up VirtualBox Bridged Network on Windows 7 Host?

    - by Tong Wang
    I have virtualbox running on a Windows 2008 server, with a guest running ubuntu 10.04. The ubuntu guest is given a static IP of 192.168.1.4, which also has openssh installed. The guest has bridged network setup, I can ping 192.168.1.4 from any machine in the LAN, the ubuntu guest can also access the LAN. However, when I try to PuTTY into the ubuntu machine, I always get "connection refused". Below are some setup details: ubuntu IP: 192.168.1.4 hosts.allow sshd : 192.168.1.38 hosts.deny ALL : ALL when I the following command, I can see that sshd is listening on port 22: lsof -i tcp:22 Any idea? EDIT: It turned out to be a wrong VirtualBox Bridged Network setup. I give the Ubuntu guest a static IP of 192.168.1.4 (assigned to eth0). Then in the Windows 7 host, in the Network and Sharing Center, there is a new connection named "VirtualBox Host-Only Network" after the bridge is setup, that connection is again given the same static IP of 192.168.1.4. Once I change the "VirtualBox Host-Only Network" to automatically obtain an IP address, it's getting a different IP address of 169.254.249.70(Tentative). And now I can SSH into 192.168.1.4 with no problem, even without touching hosts.allow and hosts.deny. I've also noticed that in the properties windows (see screenshot below) of the "VirtualBox Host-Only Network", the second checkbox, "VirtualBox Bridged Networking Driver" is unchecked. While the same checkbox of the physical NIC (that is bridged to) is checked. So my further question is: is this how VBox bridged networking supposed to be setup? Any rationale behind this? I'd appreciate if someone could provide some explaination on VBox bridged networking setup on Windows host and I'll accept it as an answer.

  • Error: kernel headers not found. (But they are in place)

    - by Guandalino
    I'm trying to install the Guest Additions in VirtualBox 4.04. Host OS is Ubuntu desktop 11.04 64bit, guest OS is Ubuntu server 11.10 64bit. $ sudo ./VBoxLinuxAdditions.run After some output this line is printed: The headers for the current running kernel were not found. But the headers are installed, at least accordingly to dpkg: $ dpkg --get-selections | grep linux-headers linux-headers-3.0.0-12 install linux-headers-3.0.0-12-server install linux-headers-server install The running kernel is: $ uname -a Linux foobar 3.0.0-12-server #20-Ubuntu SMP Fri Oct 7 16:36:30 UTC 2011 x86_64 x86_64 X86_64 GNU/Linux How do I fix things so that Guest Additions installer is able to find kernel headers? Update: added full output. The headers for the current running kernel were not found. If the module compilation fails then this could be the reason. Building the main Guest Additions module ...done. Building the shared folder support module ...fail! (Look at /var/log/vboxadd-install.log to find out what went wrong) Installing the Window System drivers ...fails! (Could not find the X.Org or XFree86 Window System). I don't care for fail #2, because that's a server and I don't need X server. But I need shared folder support. Some further detail: $ tail /val/log/vboxadd-install.log .......... cc1: some warnings being treated as errors make[2]: *** [/tmp/vbox.0/vfsmod.o] Error 1 make[1]: *** [_module_/tmp/vbox.0] Error 2 make: *** [vboxsf] Error 2

  • Install Problems on ASUS X401A Notebook

    - by tired_of_trying
    okay... I tried many approaches to install Ubuntu 12.xxx on my new Asus notebook with varying degrees of failure... First: I'm not a newbie but I'm as frustrated as one! Install background: Install from USB DVD drive: The install went well. Re-booted machine. choose ubuntu and it errors with a MBR file error (can't remember the exact wording - something to do with missing the file. Choosing to boot W7 works fine. Install from USB Stick: Couldn't get machine to recognize the .iso Install into Oracle's Vbox: Got the boot splash screen, then hangs with a zillion errors. Note: I didn't have any problems installing ubuntu in Vbox on my iMac and it run's great. Installed using wubi: Installed fine but get errors when booting ubuntu (it doesn't find the needed wubi files). I downloaded to the C: drive and tried installing from there - no luck. For kicks: I tried running Slax Linux .iso from a USB stick and it runs fine. Some Questions: Did I use the correct .iso? (I tried 12.04.0 and 12.04.1 both 32 and 64 bit versions. I simply downloaded them from the download link and didn't use/look for an alternate version. Do I need to do something special when burning the .iso to disc? What? I did read tons of posts but, no luck with finding the solution. Any help is appreciated... thanks

  • How do I organize a GUI application for passing around events and for setting up reads from a shared resource

    - by Savanni D'Gerinel
    My tools involved here are GTK and Haskell. My questions are probably pretty trivial for anyone who has done significant GUI work, but I've been off in the equivalent of CGI applications for my whole career. I'm building an application that displays tabular data, displays the same data in a graph form, and has an edit field for both entering new data and for editing existing data. After asking about sharing resources, I decided that all of the data involved will be stored in an MVar so that every component can just read the current state from the MVar. All of that works, but now it is time for me to rearrange the application so that it can be interactive. With that in mind, I have three widgets: a TextView (for editing), a TreeView (for displaying the data), and a DrawingArea (for displaying the data as a graph). I THINK I need to do two things, and the core of my question is, are these the right things, or is there a better way. Thing the first: All event handlers, those functions that will be called any time a redisplay is needed, need to be written at a high level and then passed into the function that actually constructs the widget to begin with. For instance: drawStatData :: DrawingArea -> MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO () createStatView :: (DrawingArea -> IO ()) -> IO VBox createUI :: MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO HBox createUI storeMVar field = do graphs <- createStatView (\area -> drawStatData area storeMVar field) hbox <- hBoxNew False 10 boxPackStart hbox graphs PackNatural 0 return hbox In this case, createStatView builds up a VBox that contains a DrawingArea to graph the data and potentially other widgets. It attaches drawStatData to the realize and exposeEvent events for the DrawingArea. I would do something similar for the TreeView, but I am not completely sure what since I have not yet done it and what I am thinking of would involve replacing the TreeModel every time the TreeView needs to be updated. My alternative to the above would be... drawStatData :: DrawingArea -> MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO () createStatView :: IO (VBox, DrawingArea) ... but in this case, I would arrange createUI like so: createUI :: MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO HBox createUI storeMVar field = do (graphbox, graph) <- createStatView (\area -> drawStatData area storeMVar field) hbox <- hBoxNew False 10 boxPackStart hbox graphs PackNatural 0 on graph realize (drawStatData graph storeMVar field) on graph exposeEvent (do liftIO $ drawStatData graph storeMVar field return ()) return hbox I'm not sure which is better, but that does lead me to... Thing the second: it will be necessary for me to rig up an event system so that various events can send signals all the way to my widgets. I'm going to need a mediator of some kind to pass events around and to translate application-semantic events to the actual events that my widgets respond to. Is it better for me to pass my addressable widgets up the call stack to the level where the mediator lives, or to pass the mediator down the call stack and have the widgets register directly with it? So, in summary, my two questions: 1) pass widgets up the call stack to a global mediator, or pass the global mediator down and have the widgets register themselves to it? 2) pass my redraw functions to the builders and have the builders attach the redraw functions to the constructed widgets, or pass the constructed widgets back and have a higher level attach the redraw functions (and potentially link some widgets together)? Okay, and... 3) Books or wikis about GUI application architecture, preferably coherent architectures where people aren't arguing about minute details? The application in its current form (displays data but does not write data or allow for much interaction) is available at https://bitbucket.org/savannidgerinel/fitness . You can run the application by going to the root directory and typing runhaskell -isrc src/Main.hs data/ or... cabal build dist/build/fitness/fitness data/ You may need to install libraries, but cabal should tell you which ones.

  • libvirt and VirtualBox / Getting Started

    - by Marc Lucas
    I'm trying to get started on libvirt with VirtualBox as a virtualization solution. I installed everything and VirtualBox itself is running when using their VBoxHeadless command. However, libvirt fails to connect to VirtualBox: # virsh -c vbox:///session libvir: error : could not connect to vbox:///session error: failed to connect to the hypervisor I could not find any hints in the libvirt documentation that point to whether I have to make any domain specific configuration before using virsh. Does anyone have a hint? Or even better, maybe a tutorial that works through the way of using libvirt, virsh or it's APIs (my later goal) from the ground up.

  • How to set variable size for List control item in Flex?

    - by joejax
    The following code display a list of comments using List control. The item height set to a fixed value (150), so it seems working: if the content is too long, the scrollbar shows... However, what I really want is not to set the height but let it to change according to the content size. Is there any way to accomplish this? <mx:List id="commentList" width="100%" dataProvider="{commentSet.commentArrayColl}" rowCount="{commentSet.commentArrayColl.length}" > <mx:itemRenderer> <mx:Component> <mx:VBox width="100%" height="150" > <mx:Text text="{data.commentContent}" /> <mx:Text text="{data.username} ({data.modified})"/> </mx:VBox> </mx:Component> </mx:itemRenderer> </mx:List>

  • Gtk, How to scroll at bottom of viewport list?

    - by PP
    I have created one list with GtkVBox and GtkViewPort. and i am doing the scroll by two up/down GtkButtons. GtkAdjustment* adjustment; adjustment = gtk_viewport_get_vadjustment(GTK_VIEWPORT(viewport_ptr)); gtk_adjustment_set_value(adjustment, gtk_adjustment_get_value(adjustment)+(gdouble)SCROLL_SIZE); gtk_widget_show_all(viewport_ptr); But when I add the widget to VBox it gets added at the end of the VBox as I am using gtk_box_pack_start. So i want to scroll viewport up to this newly added last widget which is at bottom of the list.
