  • UIView Animation: PartialCurl ...bug during rotate?

    - by itai alter
    Hello all, a short question. I've created an app for the iPad, much like a utility app for the iPhone (one mainView, one flipSideView). The animation between them is UIModalTransitionStylePartialCurl. shouldAutorotateToInterfaceOrientation is returning YES. If I rotate the device BEFORE entering the FlipSide, everything is okay and the PartialCurl is displayed okay. But if I enter the FlipSide and then rotate the device, while the UIElements do rotate and position themselves just fine, the actual "page curl" stays with its initial orientation. it just won't budge :) Is it a known issue? am I doing something wrong? Thanks!

  • iPhone UIWebView width does not fit after zooming operation + UIInterfaceOrientation change

    - by choonkeat
    I created a bare bones iPhone app with a UIWebView (Scales Page to Fit = YES, shouldAutorotateToInterfaceOrientation = YES) and loaded a webpage, e.g. http://stackoverflow.com/ Rotating the device shows that UIWebView is auto-resized to fit the width. Good. Incorrect: Zoom into the page and zoom out. Now rotating the device shows UIWebView in a weird width in one of the orientation (if u zoom in landscape, the portrait width is weird, vice versa). This behavior is fixed only when you navigate to another page. Correct: Load the same URL in Mobile Safari. Rotating works & the width fits regardless of the zooming exercise. Is this a UIWebView bug (probably not)? Or is there something that needs to be done to make things "just work" like in Mobile Safari?

  • Linear Layout and weight in Android

    - by Janusz
    I always read about this funny weight value in the Android documentations. Now I want to try it for the first time but it isn't working at all. As I understand it from the documentations this layout: <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <Button android:text="Register" android:id="@+id/register" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="10dip" weight="1" /> <Button android:text="Not this time" android:id="@+id/cancel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="10dip" weight="1" /> </LinearLayout> should create two buttons that are horizontally aligned and share the space equally. The problem is the two buttons don't grow to fill the space. The result is something like this: I would like the buttons to grow and fill the whole line.

  • Why isn't TextBox.Text in WPF animatable?

    - by cplotts
    Ok, I have just run into something that is really catching me off-guard. I was helping a fellow developer with a couple of unrelated questions and in his project he was animating text into some TextBlock(s). So, I went back to my desk and recreated the project (in order to answer his questions), but I accidentally used TextBox instead of TextBlock. My text wasn't animating at all! (A lot of help, I was!) Eventually, I figured out that his xaml was using TextBlock and mine was using TextBox. What is interesting, is that Blend wasn't creating key frames when I was using TextBox. So, I got it to work in Blend using TextBlock(s) and then modified the xaml by hand, converting the TextBlock(s) into TextBox(es). When I ran the project, I got the following error: InvalidOperationException: '(0)' Storyboard.TargetProperty path contains nonanimatable property 'Text'. Well, it seems as if Blend was smart enough to know that ... and not generate the key frames in the animation (it would just modify the value directly on the TextBox). +1 for Blend. So, the question became: why isn't TextBox.Text animatable? The usual answer is that the particular property you are animating isn't a DependencyProperty. But, this isn't the case, TextBox.Text is a DependencyProperty. So, now I am bewildered! Why can't you animate TextBox.Text? Let me include some xaml to illustrate the problem. The following xaml works ... but uses TextBlock(s). <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="TextBoxTextQuestion.MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480" > <Window.Resources> <Storyboard x:Key="animateTextStoryboard"> <StringAnimationUsingKeyFrames Storyboard.TargetProperty="(TextBlock.Text)" Storyboard.TargetName="textControl"> <DiscreteStringKeyFrame KeyTime="0:0:1" Value="Goodbye"/> </StringAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Window.Triggers> <EventTrigger RoutedEvent="FrameworkElement.Loaded"> <BeginStoryboard Storyboard="{StaticResource animateTextStoryboard}"/> </EventTrigger> </Window.Triggers> <Grid x:Name="LayoutRoot"> <StackPanel Orientation="Vertical" HorizontalAlignment="Center" VerticalAlignment="Center"> <TextBlock x:Name="textControl" Text="Hello" FontFamily="Calibri" FontSize="32"/> <TextBlock Text="World!"

  • Having trouble with binding

    - by Tam
    I'm not sure if I'm misunderstanding the binding in Flex. I'm using Cairngorm framework. I have the following component with code like: [Bindable] var _model:LalModelLocator = LalModelLocator.getInstance(); .... <s:DataGroup dataProvider="{_model.friendsSearchResults}" includeIn="find" itemRenderer="com.lal.renderers.SingleFriendDisplayRenderer"> <s:layout> <s:TileLayout orientation="columns" requestedColumnCount="2" /> </s:layout> </s:DataGroup> in the model locator: [Bindable] public var friendsSearchResults:ArrayCollection = new ArrayCollection(); Inside the item renderer there is a button that calls a command and inside the command results there is a line like this: model.friendsSearchResults = friendsSearchResults; Putting break points and stepping through the code I confirmed that this like gets called and the friendsSearchResults gets updated. To my understanding if I update a bindable variable it should automatically re-render the s:DataGroup which has a dataProvider of that variable.

  • Android setImageURI out of memory error

    - by Improver
    I have a very small activity that must show an image. If picture is not very small (for example 1.12 Mb 2560x1920) it produces out of memory on change screen orientation. I tried getDrawable.setCallback(null) but no luck. Where am I wrong? public class Fullscreen extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); System.gc(); setContentView(R.layout.fullscreen); ImageView imageView = (ImageView) findViewById(R.id.full_screen_image); long imageId = 2; imageView.setImageURI(Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "" + imageId)); } }

  • Big smart ViewModels, dumb Views, and any model, the best MVVM approach?

    - by Edward Tanguay
    The following code is a refactoring of my previous MVVM approach (Fat Models, skinny ViewModels and dumb Views, the best MVVM approach?) in which I moved the logic and INotifyPropertyChanged implementation from the model back up into the ViewModel. This makes more sense, since as was pointed out, you often you have to use models that you either can't change or don't want to change and so your MVVM approach should be able to work with any model class as it happens to exist. This example still allows you to view the live data from your model in design mode in Visual Studio and Expression Blend which I think is significant since you could have a mock data store that the designer connects to which has e.g. the smallest and largest strings that the UI can possibly encounter so that he can adjust the design based on those extremes. Questions: I'm a bit surprised that I even have to "put a timer" in my ViewModel since it seems like that is a function of INotifyPropertyChanged, it seems redundant, but it was the only way I could get the XAML UI to constantly (once per second) reflect the state of my model. So it would be interesting to hear anyone who may have taken this approach if you encountered any disadvantages down the road, e.g. with threading or performance. The following code will work if you just copy the XAML and code behind into a new WPF project. XAML: <Window x:Class="TestMvvm73892.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TestMvvm73892" Title="Window1" Height="300" Width="300"> <Window.Resources> <ObjectDataProvider x:Key="DataSourceCustomer" ObjectType="{x:Type local:CustomerViewModel}" MethodName="GetCustomerViewModel"/> </Window.Resources> <DockPanel DataContext="{StaticResource DataSourceCustomer}"> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=FirstName}"/> <TextBlock Text=" "/> <TextBlock Text="{Binding Path=LastName}"/> </StackPanel> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=TimeOfMostRecentActivity}"/> </StackPanel> </DockPanel> </Window> Code Behind: using System; using System.Windows; using System.ComponentModel; using System.Threading; namespace TestMvvm73892 { public partial class Window1 : Window { public Window1() { InitializeComponent(); } } //view model public class CustomerViewModel : INotifyPropertyChanged { private string _firstName; private string _lastName; private DateTime _timeOfMostRecentActivity; private Timer _timer; public string FirstName { get { return _firstName; } set { _firstName = value; this.RaisePropertyChanged("FirstName"); } } public string LastName { get { return _lastName; } set { _lastName = value; this.RaisePropertyChanged("LastName"); } } public DateTime TimeOfMostRecentActivity { get { return _timeOfMostRecentActivity; } set { _timeOfMostRecentActivity = value; this.RaisePropertyChanged("TimeOfMostRecentActivity"); } } public CustomerViewModel() { _timer = new Timer(CheckForChangesInModel, null, 0, 1000); } private void CheckForChangesInModel(object state) { Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, this); } public static CustomerViewModel GetCustomerViewModel() { CustomerViewModel customerViewModel = new CustomerViewModel(); Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, customerViewModel); return customerViewModel; } public static void MapFieldsFromModeltoViewModel(Customer model, CustomerViewModel viewModel) { viewModel.FirstName = model.FirstName; viewModel.LastName = model.LastName; viewModel.TimeOfMostRecentActivity = model.TimeOfMostRecentActivity; } public static Customer GetCurrentCustomer() { return Customer.GetCurrentCustomer(); } //INotifyPropertyChanged implementation public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } } //model public class Customer { public string FirstName { get; set; } public string LastName { get; set; } public DateTime TimeOfMostRecentActivity { get; set; } public static Customer GetCurrentCustomer() { return new Customer { FirstName = "Jim", LastName = "Smith", TimeOfMostRecentActivity = DateTime.Now }; } } }

  • UISplitViewCOntroller + TabBarCOntroller + iPad

    - by tek3
    Hi all, I am developing a tab-based iPad application in which corresponding to each tab, I have to show an UISplitViewController . I have done this by adding two navigation controllers to my tabBarController and assigning a subclass of UISplitViewController as RootViewController of both navigationController. And also I have to show both viewControllers(Master and Detail) in both modes(Potrait and Landscape). For this I have constructed a subclass of UISplitViewController in which i am overriding willAnimateRotationToInterfaceOrientation method and setting the frame of both ViewControllers as demonstrated in this link. However i am not able to set both viewControllers correctly.If my app starts in Landscape mode everything displays fine but if i open it in Potrait mode then the orientation of both ViewControllers changes. Sometimes the MasterView occupies the entire screen or sometimes both ViewControllers appear leaving a black line between them and the navigationBar. I have been banging my head over this problem since two days without any success. kindly help..

  • How to get the PrintDocumentImageableArea for a given PrintQueue without going through PrintDialog?

    - by Patrick Klug
    From MSDN (link): The type PrintDocumentImageableArea has no public constructor. Hence, the variable documentImageableArea must be declared and assigned to Nothing and only then passed to the method. This method displays a PrintDialog requiring input from the user. After the user has selected a printer, paper size, and orientation and closed the dialog, documentImageableArea points to an actual object and its properties are initialized. I have my custom print dialog and need to get the PrintDocumentImageableArea of a given PrintQueue and PrintTicket! (I need the margin's I need to apply) From what I can gather it is quite common for anything but the most basic applications to use their own custom print dialog. There must be a way to get to this information!? Any input appreciated!

  • Subview position issue after UIOrientation (rotation) change

    - by asadqamber
    I have a viewController and have added a subview in it programatically. secondView.autoresizingMask = UIViewAutoresizingFlexibleWidth; [self.view addSubview:secondView]; I guess when the device rotates, my mainViewController knows that orientation changed, but the subview (secondView) inside the mainViewController does not know this, so I change its frame to landscape size in willRotateToInterfaceOrientation. secondView.frame = CGRectMake(0, 0, 480 , 260); This does not set in the correct position, it's 11 px below the NavigationBar. Why does it start from 11 px below the navigation bar? The navigation bar shrinks when we move from portrait to landscape mode and its because of this that my subview is 11px below.

  • [WPF]ItemsControl not completely loaded @Loaded event

    - by Kaare
    Hi everyone I have a propably simple problem, that i just can't seem to figure out: I've made an ItemsControl which has its datacontext set and shows the data as pairs of Checkboxes and TextBlocs: <ItemsControl Name="listTaskTypes" Grid.Row="1" Grid.Column="2" Grid.RowSpan="2" ItemsSource="{Binding}" Margin="10,0,0,0" VerticalAlignment="Top" Loaded="listTaskTypes_Loaded"> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <CheckBox Name="checkBoxTypeId" Tag="{Binding Path=TaskTypeID}"/> <TextBlock FontSize="11pt" FontFamily="Helvetica" Text="{Binding Path=Text}" /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> My problem is that in the Loaded event of the ItemsControl, the checkboxes does not exist yet. How can i get an event when the ItemsControl is completely loaded or is this not possible?

I've checked the dalvik monitor and the error E/MapActivity(394): Couldn't get connection factory client occurs. I've find out on stackoverflow website that I should sent a gps signal or sth like this from dalvik monitor, and I've done it. Nothing happend, also I got the api key one more time, but nothing changed. here is map.xml <?xml version="1.0" encoding="utf-8"?> <!-- This file is /res/layout/mapview.xml --> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/zoomin" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="+" android:onClick="myClickHandler" android:padding="12px" /> <Button android:id="@+id/zoomout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="-" android:onClick="myClickHandler" android:padding="12px" /> <Button android:id="@+id/sat" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Satellite" android:onClick="myClickHandler" android:padding="8px" /> <Button android:id="@+id/street" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Street" android:onClick="myClickHandler" android:padding="8px" /> <Button android:id="@+id/traffic" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Traffic" android:onClick="myClickHandler" android:padding="8px" /> <Button android:id="@+id/normal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Normal" android:onClick="myClickHandler" android:padding="8px" /> </LinearLayout> <com.google.android.maps.MapView android:id="@+id/mapview" android:layout_width="fill_parent" android:layout_height="wrap_content" android:clickable="true" android:apiKey="0zPcz1VYRSpLusufJ2JoL0ffl2uxDMovgpW319w" /> </LinearLayout> here is a MapMapa.java public class MapMapa extends MapActivity { private MapView mapView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.map); mapView = (MapView)findViewById(R.id.mapview); } public void myClickHandler(View target) { switch(target.getId()) { case R.id.zoomin: mapView.getController().zoomIn(); break; case R.id.zoomout: mapView.getController().zoomOut(); break; case R.id.sat: mapView.setSatellite(true); break; case R.id.street: mapView.setStreetView(true); break; case R.id.traffic: mapView.setTraffic(true); break; case R.id.normal: mapView.setSatellite(false); mapView.setStreetView(false); mapView.setTraffic(false); break; } } @Override protected boolean isLocationDisplayed() { return false; } @Override protected boolean isRouteDisplayed() { return false; } manifest.xml <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="menu.dot" android:versionCode="1" ndroid:versionName="1.0"> <application android:label="@string/app_name" android:icon="@drawable/icon"> <uses-library android:name="com.google.android.maps" /> <activity android:name="MainActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".About"> android:label="@string/about_title" android:theme="@android:style/Theme.Dialog" > </activity> <activity android:name=".Exit"> andorid:label="@string/exit_title"> </activity> <activity android:name=".Options"> </activity> <activity android:name=".Start"> </activity> <activity android:name=".Create"> </activity> <activity android:name=".Where"> </activity> <activity android:name=".Proceed"> </activity> <activity android:name=".Finish"> </activity> <activity android:name=".Login"> </activity> <activity android:name=".OK"> </activity> <activity android:name=".UserPanel"> </activity> <activity android:name=".Managero"> </activity> <activity android:name=".Edition"> </activity> <activity android:name=".Done"> </activity> <activity android:name=".Delete"> </activity> <activity android:name=".MapMapa"> </activity> </application> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-sdk android:minSdkVersion="3" /> </manifest>

  • WPF Validation & IDataErrorInfo

    - by Jefim
    A note - the classes I have are EntityObject classes! I have the following class: public class Foo { public Bar Bar { get; set; } } public class Bar : IDataErrorInfo { public string Name { get; set; } #region IDataErrorInfo Members string IDataErrorInfo.Error { get { return null; } } string IDataErrorInfo.this[string columnName] { get { if (columnName == "Name") { return "Hello error!"; } Console.WriteLine("Validate: " + columnName); return null; } } #endregion } XAML goes as follows: <StackPanel Orientation="Horizontal" DataContext="{Binding Foo.Bar}"> <TextBox Text="{Binding Path=Name, ValidatesOnDataErrors=true}"/> </StackPanel> I put a breakpoint and a Console.Writeline on the validation there - I get no breaks. The validation is not executed. Can anybody just press me against the place where my error lies?

  • Displaying the selected item differently in ComboBox

    - by David Brunelle
    I have a combo box in which I set up an ItemTemplate that looks something like this: <ComboBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Piece.NoPiece}" Width="50" /> <TextBlock Text="{Binding Piece.Description}" Width="170" /> <TextBlock Text="{Binding Piece.Categorie.NomCategorie}" /> </StackPanel> </DataTemplate> </ComboBox.ItemTemplate> As you can see, I got three columns that let the user see different piece of information. However, I would like the selected item in the combo to display only the second column. In other word, is there a way to have an ItemTemplate that displays items in a different manner when you scroll down versus when it's closed and you only see the selection?

  • Best practices for developing bigger applications on Android

    - by Janusz
    I've already written some small Android Applications, most of them in one Activity and nearly no data that should be persistent on the device. Now I'm writing an application that needs more Activities and I'm a bit puzzled about how to organize all this. My app will download some data parse it show it to the user and then show other activities depending on the data and the user interaction. Some of that data could be cached, some of it has to be downloaded every time. Some of that data should not be downloaded freshly at the moment the orientation changes, but it should on the moment the activity is created... Another thing I'm confused about are things like a httpClient. I now for example create a new httpclient for every activity, the same thing for locationlisteners. Are there books, a blogs or documentations with patterns, examples and advice on organizing larger apps build on android? Everything I found until now are get startet tutorials leaving me alone after 60 lines of code...
