  • Storyboard elements are not sized properly on the device

    - by Joel Fischer
    In the storyboard, I am placing a table view element into a subclassed UIView. The element is not appearing on the iPad device I am running it on the same as it appears in the storyboard however. This also happens for additional content that I place into the storyboard. Below is a screenshot as it appears in the storyboard, as well as UI width/height information. And here is the description of the UI file running on the iPad. https://gist.github.com/4323186 (embedding it directly into the post is giving me problems) You'll notice that the tableview is explicitly set at 178 width, and is showing up in the description as 276 width. My initial thought was that perhaps a cell was forcing the parent to be larger (I'm very new to iOS UI development), but drilling into that shows the prototype cell it appears that the width is defined by it's parent at 178. The image views and label also are appearing in the incorrect spot, as shown in the second image below.

  • UILabel applying CGAffineTransformMakeRotation causing mysterious crash

    - by quantumpotato
    In -(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil parentController:(GameViewController *)myGameController{ Have a series of transforming labels like so: deg90 = 1.570796326794897; //....transforms background.center = CGPointMake(160,230); background.transform = CGAffineTransformMakeRotation(deg90); BetLabel.text = @"test"; BetLabel.transform = CGAffineTransformMakeRotation(deg90); That last line is crashing me with: 2010-04-13 21:04:47.858 Game[1204:207] * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (1) beyond bounds (1)' 2010-04-13 21:04:47.893 Game[1204:207] Stack: ( 864992541, 859229716, (lots of numbers) But if I comment it out, I get the text changing fine. Uh oh, just did a test.. turns out the other transforms were on UIImageViews. Apparently rotating a label in this xib is causing the crash. But in another file the transforms are working fine: newprofileentry.transform = CGAffineTransformMakeRotation(1.570796326794897); playerb0.transform = CGAffineTransformMakeRotation(1.570796326794897); playerb1.transform = CGAffineTransformMakeRotation(1.570796326794897); Tried substituting deg90 with the full float value, still the same crash. Tried cleaning cache, restarting IB and Xcode, cleaning all targets. Program has been running fine until I just added these labels. Tried deleting the label, readding and reconnecting the Outlet, too. Thanks for reading, hope someone has an idea about this. Cheers!

  • Should We Mask Passwords?

    - by Abi Noda
    From Jacob Nielson's "Stop Password Masking": Usability suffers when users type in passwords and the only feedback they get is a row of bullets. Typically, masking passwords doesn't even increase security, but it does cost you business due to login failures. What do you guys think?

  • Ruby SerialPorts

    - by Seth Archer
    I'm using the ruby serial port gem. After I open up the port I send the data I want like this. sp.write [200.chr, 30.chr, 7.chr, 5.chr, 1.chr, 2.chr, 0.chr, 245.chr].to_s It doesn't work, but if I put it in a loop of around 200 times: 200.times do sp.write [200.chr, 30.chr, 7.chr, 5.chr, 1.chr, 2.chr, 0.chr, 245.chr].to_s end It works. Any ideas on why this is happening?

  • javascript removeChild() and appendChild() VS display=none and display=block|inline

    - by Kucebe
    I'm developing a web application that shows some controls and descriptions dinamically (I don't want to use jQuery or other libraries). At this moment i make appear and disappear controls using: element.setAttribute("style", "inline"); and element.setAttribute("style", "none"); but i'm thinking about using: element.appendChild(childRef); and element.removeChild(childRef); So, which one is the best solution in terms of system speed and elegance of the code? (and of course, are there better solution?)

  • Where has my parallel port gone? ioperm(888,1,1) returns -1.

    - by marcusw
    I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

  • Android: custom view onClickEvent with X & Y locations

    - by Martyn
    Hi, I've got a custom view and I want to get the X and Y coordinates of a user click. I've found that I can only get the coordinates from the onTouchEvent and an onClickEvent won't fire if I have an onTouchEvent. Unfortunately the onTouchEventfires when the user drags the screen as well as clicking. I've tried to differentiate between the two, but I still get the code firing when I'm dragging: public boolean onTouchEvent(MotionEvent event) { int action = event.getAction(); if (action == MotionEvent.ACTION_DOWN) { //fires on drag and click I've had a look at this but as I mentioned above I don't think the solution there will work as I can't get the onClick and the onTouch events working at the same time. Maybe I'm doing something wrong in this respect, is there a normal way of dealing with capturing user input on custom events? Should I be able to use the onClick and onTouch events at the same time? Thanks, Martyn

  • Why use I-prefix for interfaces in Java?

    - by Lars Andren
    Is there some reason why people use I-prefix for interfaces in Java? It seems to be a C#-convention spilling over. For C# it makes sense, as the answers to this question explains. However, for Java a class declaration clearly states which class that is extended and which interfaces that are implemented: public class Crow extends Animal implements Bird I think Joshua Bloch didn't suggest this in Effective Java, and I think he usually makes a lot of sense. I get the I-verbing as presented in an answer to the question above, but is there some other use with this convention for Java?

  • Do you ever create fake progress bars?

    - by wrongusername
    Do you (and would you) ever create progress bars that are just there to keep the client happy and moves without reflecting the true progress of the program? I remember reading about this somewhere, and am wondering if there are other developers that do it too...

  • Check if UINavigationItem title is truncated

    - by PartiallyFinite
    I want to check whether the title of a UINavigationItem is truncated. I set the title like this: self.navigationItem.title = whatever. I know I can check if the text in a UILabel is truncated like this: CGSize size = [label.text sizeWithFont:[UIFont fontWithName:@"myfont" size:18.0]]; if (size.width > label.bounds.size.width) { // set a shorter title } And I can even find the UINavigationItemView object in which the title is displayed like so: UIView *navItemView; for (UIView *view in self.navigationController.navigationBar.subviews) { if ([view isKindOfClass:NSClassFromString(@"UINavigationItemView")]) { navItemView = view; } } But I cannot apply this method to the navItemView because is always seems to have a width of exactly 58, which is much less than the title in it, so according to that, it would appear that the title is truncated, even when it isn't. So, my question comes down to this: How do I find the width of the title displayed in the UINavigationItem? UPDATE: I have found a solution to my problem, but it isn't exactly ideal, perfect, or reliable, so I am not marking it as an answer yet. If anyone has any better solutions, please share them.

  • Why is my iPhone SDK 3.2 iPad code showing a white screen?

    - by Anthony Glyadchenko
    I'm trying to get a UISplitViewController working with an iPad app. I have the table view controller linked up under the Master pane and a plain UIView under the Detail view. I also have [window addSubview:splitView.view]; in my code. For some reason I just get a white screen even though the table view controller code is properly coded and linked under my nib. Any help would be great! Thanks! Here's where you can find the code: http://drop.io/s28bu4t/asset/mydevice-hd-zip

  • How do I make this scroll layout work?

    - by JuiCe
    I am currently trying to get my UI to have a Title Bar, a bottom Button bar, with a ScrollView in between. I can get bits and pieces of it to work, but once I get a different piece working, the old part goes back to not showing up. Here is a picture of my UI on the left, with what I want it to look like on the right...(sorry for the sloppiness, I edited it in MS Paint :P ) To sum it up, I want the Version and Type fields to be moved with room for the other TextViews in the XML file, and I want both buttons to appear on the bottom bar. EDIT : The buttons on the bottom should be equal in size, I'm not too talented in making boxes in MS Paint EDIT 2 : Sorry....here is my XML file <?xml version="1.0" encoding="UTF-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:weightSum="1.0" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:text="SN : " /> <TextView android:id="@+id/serialNumberView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:text="Ver : " /> <TextView android:id="@+id/versionView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:text="Type : " /> <TextView android:id="@+id/typeView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> </LinearLayout> <ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" android:layout_weight="1"> <CheckBox android:id="@+id/floatCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Float" /> <CheckBox android:id="@+id/tripCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Trip" /> <CheckBox android:id="@+id/closeCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Close" /> <CheckBox android:id="@+id/blockedCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Blocked" /> <CheckBox android:id="@+id/hardTripCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hard Trip" /> <CheckBox android:id="@+id/phaseAngleCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Phase angle wrong for closing" /> <CheckBox android:id="@+id/diffVoltsCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Differential volts too low" /> <CheckBox android:id="@+id/networkVoltsCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Network volts too low to close" /> <CheckBox android:id="@+id/usingDefaultsCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Using Defaults( Reprogram )" /> <CheckBox android:id="@+id/relaxedCloseActiveCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Relaxed Close Active" /> <CheckBox android:id="@+id/commBoardDetectedCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Comm Board Detected" /> <CheckBox android:id="@+id/antiPumpBlock" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Anti-Pump Block" /> <CheckBox android:id="@+id/motorCutoffCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Motor Cutoff Inhibit" /> <CheckBox android:id="@+id/phaseRotationCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Phase Rotation Wrong" /> <CheckBox android:id="@+id/usingDefaultDNPCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text= "Using Default DNP Profile" /> </LinearLayout> </ScrollView> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_weight="1" > <Button android:id="@+id/button3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Back" /> <Button android:id="@+id/button3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Read" /> </LinearLayout> </LinearLayout>

  • Why are Views loaded from nibs being placed 20 pixels down from the status bar?

    - by rickharrison
    I am trying to set up a layout as such in an iPad application. It will have three major views, which make up the whole screen. The views will be stacked one on top of the other, each taking up the full width. I have one major nib file which accounts for the entire screen space. In that nib file, I am instantiating the three view controllers with outlets. Then I have this code: - (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:controllerOne.view]; [self.view addSubview:controllerTwo.view]; [self.view addSubview:controllerThree.view]; } This adds the views on top of one another and 20 pixels lower. However, after rotating to landscape and back they are right under the status bar. Do you know what would be causing this?

  • Window 'onscreen' size puzzle

    - by Bender
    Okay, a REALLY fundamental question about window sizes here... If I create an NSWindow in IB, set its size to 216 x 144 points (exactly 3 inches by 2 inches) then print the window, it measures exactly what I set it to in IB. However, the onscreen display size measures approximately 156 x 105 points. What causes this, and is there any way to force the window to display at the required size onscreen? I ultimately want to draw to this (semi-transparent) window then use it as a full-sized overlay for comparison against a separately loaded scanned image of known size.

  • How to make Spring accept fluent (non-void) setters?

    - by Chris
    Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One") .setProperty2("Two") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris

  • Gigantic Tabs in Eclipse on Ubuntu

    - by Zack
    Short version: How do I make a short version of Eclipse's tabs & toolbars in Ubuntu? I've been looking around for a fix to this on Google, but to no avail. With any GTK theme, I still have this same issue and it's very, very annoying--to the point where I've stopped using Eclipse in favor of gEdit. However, after running pylint from a terminal too. many. times. I've decided I need to find a solution to this issues with Eclipse so I can have PyDev back. Here's what the tabs look like: As you can see, not only are the tabs exaggerated, but the toolbar is, too: so is the toolbar on the bottom; so are the tabs in the bottom pane. Overall, it's eating up a lot of screen space, which is a hard item to come by on a 17" screen. Any suggestions/fixes?

  • jQuery UI: Drag and clone from original div, but keep clones

    - by Nic Hubbard
    I have a div, which has jQuery UI Draggable applied. What I want to do, is click and drag that, and create a clone that is kept in the dom and not removed when dropped. Think of a deck of cards, my box element is the deck, and I want to pull cards/divs off that deck and have them laying around my page, but they would be clones of the original div. I just want to make sure that you cannot create another clone of one of the cloned divs. I have used the following, which didn't work like I wanted: $(".box").draggable({ axis: 'y', containment: 'html', start: function(event, ui) { $(this).clone().appendTo('body'); } });
