  • Fixing parent controller's elements after screen orientation

    - by Jonas Anderson
    I have a tab bar application with mixed orientation support for only some views. One of the child view controller shown from one of the tab's navigation controller is displayed only in Landscape mode. In order to accomplish this, I've done the view transformation for the child view as suggested here: Is there a documented way to set the iPhone orientation? The only problem I'm seeing is that after I've performed the orientation adjustment for the child controller and then readjusted orientation back to normal on its dismissal, the contents of the (parent) navigation controller is still shown with Landscape mode dimensions despite the navigation controller reporting the correct value for the interfaceOrientation. How do I ensure that view's size is reset to match the orientation without hardcoding screen dimensions? I have the following in the root navigation controller's viewWillAppear (invoked after the child controller is dismissed): - (void)viewWillAppear:(BOOL)animated { NSLog(@"viewFrame: (%2f, %2f), width: %2f, height: %2f\n", self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height); // Frame values are (0, 0) for (x,y) width: 320, height: 367 before I // displayed child controller. // Frame values are (0,0) width: 480, height: 219 after returning from child // controller -- still has the landscape dimensions NSLog(@"orientation: %d", self.interfaceOrientation); // reports portrait as expected } I've tried to invoke 'layoutIfNeeded' as well as 'setNeedsDisplay' on the view but neither of them bring the view contents into the correct display. Any suggestions would be greatly appreciated.

  • How can I automatically update the title in an xterm running screen?

    - by Nathan Fellman
    This is a bit of a followup to this question. I'm working in tcsh within GNU screen in an xterm. I have the following in my .cshrc: alias res_t 'xtset -t %h:%d "(%u:%g)" %e' # reset titlebar res_t # reset title right now alias precmd res_t And this works fine! However, when I run screen I see that the title doesn't get updated with the current directory. How can I make screen update the xterm title?

  • Screen Snip/Capture Utility callable from API or command line?

    - by Raymond
    I am looking for a screen capture tool that is controllable from the command line. Ideally I would pass the filename, and possibly some options (capture mouse pointer or not, etc..), then it would take control, allow the user to select a region of the screen, and then save it to the specified file and disappear. screensnip.exe /output c:\users\public\pictures\screenshot.png /hidecursor user draws rectangle on screen control passes back to batch file, script, etc....

  • Windows 7: How to disable auto-maximize/resize window (aero-snap) when near screen edge?

    - by glenneroo
    Whenever I drag or resize a window near any edge or corner of either monitor, Windows wants to maximize or resize the window for me in several different ways: dragging a window near a corner offers resize to full-screen dragging directly to the corner offers half-screen maximize resizing to top or bottom edges offers a vertical maximize (one long strip from top to bottom) Actually, now that I think about it the 3rd one isn't so bad, its just the full and half-screen maximize features that drives me mad. Is there a registry hack to disable these settings, preferably independently?

  • High Lock Wait ratio in MySQL

    - by FunkyChicken
    on my site I log every pageview (date,ip,referrer,page,etc) in a simple mysql table. This table gets very little selects (3 per minute), but a lot of inserts. (about 100 per second) Today I changed this table from an InnoDB table to a MEMORY table, this made sense to me to prevent unnecessary hard disk IO. I also prune this table once per minute, to make sure it never get's too big. -- Performance wise, things are running fine. But I noticed that while running tuning-primer, that my Current Lock Wait ratio is quite high. Current Lock Wait ratio = 1 : 561 My question: Should I worry about this Lock Wait Ratio? And is there something I can change in my my.cnf to improve things so that the lock wait ratio isn't so high?

  • How do I ask screen to behave like a standard bash shell?

    - by thornomad
    Just learned about the screen command on linux - it is genius. I love it. However, the actual terminal/prompt in screen looks and behaves differently than my standard bash prompt. That is, the colors aren't the same, tab completion doesn't seem to work, etc. Is there a way I can tell screen to behave just like a normal (at least, normal as in what I am used to) bash prompt ?

  • Is it possible to prevent windows in Mac OS from opening below the bottom edge of the screen?

    - by user31262
    When opening a new window in finder, the new window will go below the screen. This is not a big deal, but when using macvim or terminal it can be annoying since your command prompt is now hidden. Firefox seems to be smarter, it never overlaps below the screen. Same deal for the right hand side of the screen, windows often open with their right edge cut off. Is there any way to prevent this?

  • Is there any software that can capture the screen and turn it into a fake webcam input?

    - by rjmunro
    Is there any software that can capture the screen and turn it into a webcam-type input so that you can easily record and/or broadcast your screen with regular video software? Edit: Just to be clear, I'd like to be able to use it live as an input to video conferencing software as well as for making recordings with video editing software. Bonus points if it allows me to capture a screen remote from the computer that is sending the video (for example by connecting to another computer with VNC). So it should show up as an input alongside any webcams I have installed, but instead of being a camera, it should be whatever is on the screen.

  • Mixing synchronized() with ReentrantLock.lock()

    - by yarvin
    In Java, do ReentrantLock.lock() and ReetrantLock.unlock() use the same locking mechanism as synchronized()? My guess is "No," but I'm hoping to be wrong. Example: Imagine that Thread 1 and Thread 2 both have access to: ReentrantLock lock = new ReentrantLock(); Thread 1 runs: synchronized (lock) { // blah } Thread 2 runs: lock.lock(); try { // blah } finally { lock.unlock(); } Assume Thread 1 reaches its part first, then Thread 2 before Thread 1 is finished: will Thread 2 wait for Thread 1 to leave the synchronized() block, or will it go ahead and run?

  • symfony/zend integration - blank screen

    - by user142176
    Hi, I need to use ZendAMF on a symfony project and I'm currently working on integrating the two. I have a frontend app with two modules, one of which is 'gateway' - the AMF gateway. In my frontend app config, I have the following in the configure function: // load symfony autoloading first parent::initialize(); // Integrate Zend Framework require_once('[MY PATH TO ZEND]\Loader.php'); spl_autoload_register(array('Zend_Loader', 'autoload')); The executeIndex function my the gateway actions.class.php looks like this // No Layout $this->setLayout(false); // Set MIME Type $this->getResponse()->setContentType('application/x-amf; charset='.sfConfig::get('sf_charset')); // Disable cause this is a non-html page sfConfig::set('sf_web_debug', false); // Create AMF Server $server = new Zend_Amf_Server(); $server->setClass('MYCLASS'); echo $server->handle(); return sfView::NONE; Now when I try to visit the url for the gateway module, or even the other module which was working perfectly fine until this attempt, I only see a blank screen, with not even the symfony dev bar loaded. Oddly enough, my symfony logs are not being updated as well, which suggests that Synfony is not even being 'reached'. So presumably the error has something to do with Zend, but I have no idea how to figure out what the error could be. One thing I do know for sure is that this is not a file path error, because if I change the path in the following line (a part of frontendConfiguration as shown above), I get a Zend_Amf_Server not found error. So the path must be correct. Also if I comment out this very same line, the second module resumes to normality, and my gateway broadcasts a blank x-amf stream. spl_autoload_register(array('Zend_Loader', 'autoload')); Does anyone have any tips on how I could attach this problem? Thanks P.S. I'm currently running an older version of Zend, which is why I am using Zend_Loader instead of Zend_autoLoader (I think). But I've tried switching to the new lib, but the error still remains. So it's not a version problem as well.

  • shader coding: calculate screen coordinates of fragment

    - by Jay
    Good morning, I'm new to shader coding and trying to implement some visual effects code in shaders using billboards. (Yes, I couldn't have picked anything harder to start with, but I'm lucky that way) Setup: I have rendered the full screen z depth to an array of floats in a previous pass. In the fragment shader I need the scene depth where the rendered fragment is displayed (to see if it's occluded). I can use tex2d() to get the depth value if I have the screen coordinates of the point being rendered in the fragment shader. Question: In the fragment shader how do you calculate the screen coordinates of the pixel (in the range 0-1.0)? Is the position passed to the fragment shader a pixel offset? If so, I guess it would be: float2( position.x / screen-width, position.y / screen-height ) Thanks for any help/

  • KVM swtitch , screen resolution problem

    - by Vagelism
    I use the lates ubuntu version. Till to day I use it with an acer trravelmate4070 and an LG screen in order to expand my destkop. Works great. Till today that I desided to connect my LG screen to a KVM switch in order to share the big screen with an other pc when I need it. In the KVM switch the resolution is lower and I can not manually change it. I read many solutions about making an .conf file but since I am new to Ubuntu I am afraid , more over I realized that these articles talk for the same problem but not as an expantion screen but as a main screen. Any idea how to config correct this file? I send the links of these articles here: http://robert.penz.name/219/workarou...-kvm-switches/ Where is the X.org config file? How do I configure X there? Thank you!

  • Ouya build experiencing odd graphical artifacts, screen half black

    - by Neeko
    I'm witnessing very odd graphical artifacts when I run my Unity game on Ouya. After the Unity splash screen, the game loads with the screen half black. This seemingly has started occurring out of the blue. It also doesn't occur in the editor or the standalone build, only on Ouya. I can't think of a single reason why this would be happening. If I open the Ouya menu screen and close it, the game returns to normal; somewhat, as there may be some artifacts lingering but the screen isn't half black like in the screen shot above. I know there's not much to go off of, but any insight into why this may be happening is greatly appreciated.

  • horizontal line across screen at startup

    - by Debbie Poole
    I recently ran an upgrade from 12.04 to 12.10 and was using Nvidia current tested drivers and all seemed ok at first. Then suddenly every time I started the computer and shutdown, the graphical plymouth logo changed to text.The only changes I made to try to correct this issue were; sudo apt-get --purge remove nvidia-current nvidia-settings sudo apt-get --purge autoremove sudo apt-get clean sudo apt-get update sudo apt-get install nvidia-current and this made no change at all to the display. Then I read somewhere that Nouveau drivers may be the answer, so I installed them to use instead, and hey presto, the shutdown screen displays the Plymouth splash. However with startup, I get a stable purple screen, for a while, and than a thick black horizontal line appears, really ugly-looking, and then the loging screen appears to be ok. Can I correct the login screen same as the shutdown screen?

  • Reduce boot time between grub menu and login screen

    - by Sudheer
    I use Ubuntu 14.04 LTS version which used to boot fast at beginning but not i loads very slow. I searched for this but can't find suitable answers. so i want to reduce my boot time which is now around 1min 12sec (boot chart) overall but i noticed its taking a longtime after grub menu and before login screen. A Blank screen appears after grub waiting... then login screen appears. I want to know a way to reduce that blank screen time(or if possible remove) and get login screen as fast as possible. I already removed several of my startup applications. Getting desktop after log-in is fast. I don't want to remove unity and install light desktop envinorments like Xfce and Lxde. Here is my boot-chart image Thanks in advance

  • Resuming from hibernation shows a fuzzy "static" screen

    - by Ross
    When I resume from hibernation in Ubuntu 10.10 the screen shows static, very similar to what you see on an analogue TV that hasn't been tuned properly. This also occurs on boot from shut down, but only for a moment after the Plymouth boot screen. The static lasts for at least 5 minutes. An odd thing that happens is that the mouse pointer, as a lighter square of static, becomes visible and you can move it around. Attempting to change into a terminal (i.e. Ctrl+Alt+F1) doesn't seem to work (and I'm not sure if that can be done from the login screen). Resuming from suspend has different issues - vertical lines appearing for a second before appearing to be in terminal mode (blinking cursor) and then going to the lock screen. I'm running Ubuntu 10.10 on a Dell Studio 15 with ATI graphics, however I'm not using the proprietary drivers as I had issues with dual-screen support, so it's the generic X.org drivers being used.

  • How to make 8.04's screen saver enter screen into standby?

    - by Android Eve
    I am using Ubuntu 8.04 and despite using 'gnome-power-manager' to set dpms_method_ac to 'off' for backlight, the screen will not enter standby after set time. Also, "Put display to sleep when inactive for:" (via System-Preferences-Power Management) is already set to 1 minute. Interestingly enough, this only happens when I am logged in. When I am logged out, the screen does go into standby after set time. So I know it's not the screen... Any idea how make Ubuntu 8 screen saver enter screen into standby, while logged in?

  • How to develop screen resolution independent smart device application in C#?

    - by Shailesh Jaiswal
    I am developing smart device application in C#. I am developing this application for 240*320 screen resolution. I want to make this application screen resolution independent so that it can run on different mobile devices with different screen resolutions. Currently I am testing my application on different emulators for platform- Pocket PC 2003, Windows mobile 6 standard SDK & Windows Mobile 6 professional SDK . When I run the application on emulator for 240*320 screen resolution or less than that it works well ( only it provide the horizontal & vertical scrall bar in case of resolution less tha 240*320). If I run my application on emulator with more than 240*320 screen resolution its User Inferface gets badly affected. How to make the smart device application screen resolution independent ? Can you provide me the code or link through which i can resolve the above issue? Is there any setting for making the application screen resolution independent?

  • BlackBerry - Multiple Screens or Single Screen with Content Manager?

    - by Max Gontar
    Hi! I've seen projects which use many screens each one for different layout and functionality. I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards). But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities. I can see such advantages of having single screen in app: keep same decoration design and menu or toolbar (which may be also achieved with inheritance) keep single screen in ui stack (which may be achieved by pop/push screen) easy to handle data over application Can you tell other advantages/disadvantages of single screen app? When its better to use this approach? Thank you!
