  • using Unity Android In a sub view and add style and actionbar

    - by aeroxr1
    I exported a simple animation from Unity3D (version 4.5) in android project. With eclipse I modified the manifest and added another activity. In this activity I put a button that it makes start the animation,and this is the result. The action bar appear in the main activity but it doesn't in the unity's activity :( This is the unity's activity's code : package com.rabidgremlin.tut.redcube; import android.app.NativeActivity; import android.content.res.Configuration; import android.graphics.PixelFormat; import android.os.Bundle; import android.view.KeyEvent; import android.view.MotionEvent; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager; import com.unity3d.player.UnityPlayer; public class UnityPlayerNativeActivity extends NativeActivity { protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code // Setup activity layout @Override protected void onCreate (Bundle savedInstanceState) { //requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(savedInstanceState); getWindow().takeSurface(null); //setTheme(android.R.style.Theme_NoTitleBar_Fullscreen); getWindow().setFormat(PixelFormat.RGB_565); mUnityPlayer = new UnityPlayer(this); /*if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true)) getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); */ setContentView(mUnityPlayer); mUnityPlayer.requestFocus(); } // Quit Unity @Override protected void onDestroy () { mUnityPlayer.quit(); super.onDestroy(); } // Pause Unity @Override protected void onPause() { super.onPause(); mUnityPlayer.pause(); } // eliminiamo questa onResume() e proviamo a modificare la onResume() // Resume Unity @Override protected void onResume() { super.onResume(); mUnityPlayer.resume(); } // inseriamo qualche modifica qui // This ensures the layout will be correct. @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); mUnityPlayer.configurationChanged(newConfig); } // Notify Unity of the focus change. @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); mUnityPlayer.windowFocusChanged(hasFocus); } // For some reason the multiple keyevent type is not supported by the ndk. // Force event injection by overriding dispatchKeyEvent(). @Override public boolean dispatchKeyEvent(KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_MULTIPLE) return mUnityPlayer.injectEvent(event); return super.dispatchKeyEvent(event); } // Pass any events not handled by (unfocused) views straight to UnityPlayer @Override public boolean onKeyUp(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onTouchEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } /*API12*/ public boolean onGenericMotionEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } } How can I add the action bar and the style of the first activity to unity's animation activity ?

  • What do you do to balance the upper or lower case style to name file or folder between work and life? [on hold]

    - by sojyq
    I am a programmer from China. And I like to use English words to name my files and folders Whether it is for work or life. For example, suck as Movie, Work, QtProjects, Music and so on.And I keep the habit of initial the first letter for file name or folder name in Windows. But now I work on Ubuntu, and I found that all file name and folder name are lowercase in addition to the default folder such as Music, Movie and so on. And then I realize that in Linux world, most peoloe like to use all lowercase to name their files and folders for two reasons (1. Linux is Case sensitive. 2. It is fast for shell command.). And after work, when I switch from Linux to Windows, I confuse to use all lowercase or the first letter uppercase style to name my files in Windows. I'm caught in a dilemma. I think that all lowercase is more efficiency but the first letter uppercase is more readable. I thought for a long time and want to come up with a good answer to blance the two style name conversion. But I failed. I want to ask you that how you balance the uppercase or lowercase habbit in Windows, Mac, Linux between work and personal life style? Thank you very much! (My current solution is that when I am in Linux, I use all lowercase for files and folders, but when I am in Windows and Mac OS X, I couldn't find a good reason to convince me to use all lowercase ( I think in Windows and Mac OS X, the first letter uppercase style for me is more readable and beautiful).

  • Android ListView style

    - by xger86x
    Hi, I have a question about list views. I hope someone knows the solution, because I have been trying to solve this problem all weekend. I have a custom list view in which every row have a custom .xml (item_row.xml) with a set color background for the row item. <?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="70dip" android:orientation="vertical" android:background="@drawable/list_bg"> The problem is that when I try to make a selector for the list. I want two things: When the item is focused, the typical orange rectangle should appear over it, and the same When the item is pressed. I have proved with a selector and a custom style but all I get is or the selector doesn't appear or the selector covering the item so I can't see it. If anyone could help me with finding the right code I would be very grateful. Thanks

  • overridden three20 TTDefaultStyleSheet style not working

    - by funkadelic
    hi, i recently got three20 integrated into my app and am trying to override the default toolbar color in TTWebController. In TTWebController.m:118 I see that this is setting the toolbar's tintColor: _toolbar.tintColor = TTSTYLEVAR(toolbarTintColor); So I created my own stylesheet that subclasses TTDefaultStyleSheet and overrides toolbarTintColor FooStyleSheet.h: #import <Three20Style/Three20Style.h> #import <Three20Style/TTStyleSheet.h> #import <Three20Style/TTDefaultStyleSheet.h> @interface FooStyleSheet : TTDefaultStyleSheet @property (nonatomic, readonly) UIColor* toolbarTintColor; @end FooStyleSheet.m: #import "FooStyleSheet.h" @implementation RaptrStyleSheet - (UIColor*)toolbarTintColor { return RGBCOLOR(0, 0, 0); // should override TTDefaultStyleSheet } @end and in my application:didFinishLaunchingWithOptions: i set my default stylesheet [TTStyleSheet setGlobalStyleSheet:[[[FooStyleSheet alloc] init] autorelease]]; but when I view the TTWebController, it doesn't inherit my tintColor. If I edit TTDefaultStyleSheet.m directly: - (UIColor*)toolbarTintColor { return [UIColor blackColor]; } it works as expected. Is there something I am overlooking that is preventing my style to be picked up? thanks, -norm

  • Multiple calls with Simple Modal OSX Style Dialog

    - by Brad Langdon
    I am using Simple Modal, the OSX style version. I have two calls to the modal and therefore two versions of content. When either of the buttons is clicked it selects only the first lot of content. There is nowhere to put a hook on the content like most modal windows as there is no javascript on the page to add parameters... only an external .js file which I don't want to touch for obvious reasons. Can anyone help me with this problem? Click here to view the page

  • Loading FireMonkey style resourses with RTTI

    - by HeMet
    I am trying to write class that inherits from FMX TStyledControl. When style is updated it loads style resource objects to cache. I created project group for package with custom controls and test FMX HD project as it describes in Delphi help. After installing package and placing TsgSlideHost on the test form I run test app. It’s work well, but when I close it and try to rebuild package RAD Studio says “Error in rtl160.bpl” or “invalid pointer operation”.

  • jQuery UI Autocomplete - style like a standard <SELECT>

    - by jkohlhepp
    I'm on the verge of starting a new web application that is likely to have need for both standard, simple dropdowns as well as more feature-rich autocomplete controls for longer lists of values, better type ahead behavior, etc. I'm planning on using the jQuery UI Autocomplete widget along with some combobox behavior as detailed here: http://jqueryui.com/demos/autocomplete/#combobox My concern is that "out of the box" the Autocomplete widget looks very different than a standard control. Since is not easy to skin/style, I'm hoping to adjust the Autocomplete to look & feel as close to the as possible, except in the cases where the increased functionality justifies a different L&F. What is the best way to go about reskinning the Autocomplete to look more like a ? Has this already been done somewhere? Should I use jQuery UI theming? Other options?

  • C# Winforms vs WPF

    - by m0s
    Hi pros, I am a student and I do freelance here and there when I have opportunity. I believe my strongest language is C#. I don't really know what is going on in real programming world, so I was wondering if WPF did take over WinForms? I know the differences between two and how two can be used simultaneously but, I just don't want to invest my time in learning dying technologies, I hope you understand. So, for windows desktop programming what would you recommend to master WinForms, WPF or maybe both? I also get a lot that desktop programming is dead already and one should only care about learning web programming. Thanks for attention, any comments are greatly appreciated.

  • Using bindings to control column order in a DataGrid

    - by DanM
    Problem I have a WPF Toolkit DataGrid, and I'd like to be able to switch among several preset column orders. This is an MVVM project, so the column orders are stored in a ViewModel. The problem is, I can't get bindings to work for the DisplayIndex property. No matter what I try, including the sweet method in this Josh Smith tutorial, I get: The DisplayIndex for the DataGridColumn with Header 'ID' is out of range. DisplayIndex must be greater than or equal to 0 and less than Columns.Count. Parameter name: displayIndex. Actual value was -1. Is there any workaround for this? I'm including my test code below. Please let me know if you see any problems with it. ViewModel code public class MainViewModel { public List<Plan> Plans { get; set; } public int IdDisplayIndex { get; set; } public int NameDisplayIndex { get; set; } public int DescriptionDisplayIndex { get; set; } public MainViewModel() { Initialize(); } private void Initialize() { IdDisplayIndex = 1; NameDisplayIndex = 2; DescriptionDisplayIndex = 0; Plans = new List<Plan> { new Plan { Id = 1, Name = "Primary", Description = "Likely to work." }, new Plan { Id = 2, Name = "Plan B", Description = "Backup plan." }, new Plan { Id = 3, Name = "Plan C", Description = "Last resort." } }; } } Plan Class public class Plan { public int Id { get; set; } public string Name { get; set; } public string Description { get; set; } } Window code - this uses Josh Smith's DataContextSpy <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" xmlns:mwc="http://schemas.microsoft.com/wpf/2008/toolkit" Title="Main Window" Height="300" Width="300"> <Grid> <mwc:DataGrid ItemsSource="{Binding Plans}" AutoGenerateColumns="False"> <mwc:DataGrid.Resources> <local:DataContextSpy x:Key="spy" /> </mwc:DataGrid.Resources> <mwc:DataGrid.Columns> <mwc:DataGridTextColumn Header="ID" Binding="{Binding Id}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.IdDisplayIndex}" /> <mwc:DataGridTextColumn Header="Name" Binding="{Binding Name}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.NameDisplayIndex}" /> <mwc:DataGridTextColumn Header="Description" Binding="{Binding Description}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.DescriptionDisplayIndex}" /> </mwc:DataGrid.Columns> </mwc:DataGrid> </Grid> </Window> Note: If I just use plain numbers for DisplayIndex, everything works fine, so the problem is definitely with the bindings. Update 5/1/2010 I was just doing a little maintenance on my project, and I noticed that when I ran it, the problem I discuss in this post had returned. I knew that it worked last time I ran it, so I eventually narrowed the problem down to the fact that I had installed a newer version of the WPF Toolkit (Feb '10). When I reverted to the June '09 version, everything worked fine again. So, I'm now doing something I should have done in this first place: I'm including the WPFToolkit.dll that works in my solution folder and checking it into version control. It's unfortunate, though, that the newer toolkit has a breaking change.

  • What is the C# static fields naming convention?

    - by Matt
    I have recently started using ReSharper which is a fantastic tool. Today I came across a naming rule for static fields, namely prefixing with an underscore ie. private static string _myString; Is this really the standard way to name static variables? If so is it just personal preference and style, or does it have some sort of lower level impact? Eg Compilation JIT etc? Where does this style originate from? I have always associated it with C++, is that correct?

  • ICommand.CanExecute being passed null even though CommandParameter is set...

    - by chaiguy
    I have a tricky problem where I am binding a ContextMenu to a set of ICommand-derived objects, and setting the Command and CommandParameter properties on each MenuItem via a style: <ContextMenu ItemsSource="{Binding Source={x:Static OrangeNote:Note.MultiCommands}}"> <ContextMenu.Resources> <Style TargetType="MenuItem"> <Setter Property="Header" Value="{Binding Path=Title}" /> <Setter Property="Command" Value="{Binding}" /> <Setter Property="CommandParameter" Value="{Binding Source={x:Static OrangeNote:App.Screen}, Path=SelectedNotes}" /> ... However, while ICommand.Execute( object ) gets passed the set of selected notes as it should, ICommand.CanExecute( object ) (which is called when the menu is created) is getting passed null. I've checked and the selected notes collection is properly instantiated before the call is made (in fact it's assigned a value in its declaration, so it is never null). I can't figure out why CanEvaluate is getting passed null.

  • functional-style datatypes in Python

    - by Danny Roberts
    For anyone who's spent some time with sml, ocaml, haskell, etc. when you go back to using C, Python, Java, etc. you start to notice things you never knew were missing. I'm doing some stuff in Python and I realized what I really want is a functional-style datatype like (for example) datatype phoneme = Vowel of string | Consonant of voice * place * manner datatype voice = Voiced | Voiceless datatype place = Labial | Dental | Retroflex | Palatal | Velar | Glottal datatype manner = Stop | Affricate | Fricative | Nasal | Lateral type syllable = phoneme list Does anyone have a particular way that they like to simulate this in Python?

  • Style Switcher & Text Resizer Combined?

    - by Stephen
    Hi there, I've came across various style switchers that allow you to change the stylesheet (i.e. Light, Dark, High Contrast), and carious text-resizers that allow you to resize the test (usually with Three A's, small, medium and large). However, I can't seem to find a single switcher/resizer that works well together by allowing permutations of the two. i.e. so the user can choose a dark background with small text, or a dark background with large text, etc. I can only seem to get this working where the user can choose one or the other styles (large text or High Contrast, not a combination of the two). Any ideas on anything that may be suitable for this at all? Thanks, Stephen

  • Dynatree multi - selection implementaion ala Windows style

    - by gnomixa
    I would like to implement windows style multi-selection: when user holds CTRL key and selects several nodes of the tree. Dynatree (from here http://wwwendt.de/tech/dynatree/doc/dynatree-doc.html) by default has checkboxes for node selection which my client doesn't seem to like. My question is, is it possible to implement what I need using provided set of callbacks? also, curently, when I hold CTRL key and click on the node, it opens a new window. Is there any way to suppress this functionality? i am guess I would have to do through CSS?

  • How to style alternating rows in asp.net mvc

    - by YeahStu
    I am using a <% foreach ...% loop to list a collection of items on my website. I want to add a different background color for the style of alternating rows in my list. I have found a way to do this but I am not satisfied with it as it seems like a hack. Here is what I have done to solve it so far: <table> <% int counter = 0; foreach (var item in Model) { counter++; if (counter % 2 == 0) { %> <tr class="colorfull"> <% } else { %> <tr> <% } %> ... Is there a best practice that I am missing that people are using for this scenario in ASP.NET MVC?

  • Bound Command not firing on another viewModel? What Am I doing wrong?

    - by devnet247
    Hi I cannot seem to bind a command to a button.I have a treeview on the left showing Country City etc.. And I tabcontrol on the right. do I This uses 4 viewModels rootviewModel-ContinentViewModel-CountryViewModel-CityViewModel What I am building is based on http://www.codeproject.com/KB/WPF/TreeViewWithViewModel.aspx Now on one of the tabs I have a Toolbar with a button "TestButton" that I have mapped in zaml. This does not fire! The reason is not firing is because I m binding the RootViewModel but the command that is bound in zaml is in the cityViewModel. How Do I pass the datacontext from one view to the other? or how do I make the button fire. I need the command to be in the cityViewModel. Any Suggestions on how I bind it? View "WorldExplorerView" where I bind the main DataContext public partial class WorldExplorerView { public WorldExplorerView() { InitializeComponent(); var continents = Database.GetContinents(); var rootViewModel = new RootViewModel(continents); DataContext = rootViewModel; } } CityViewModel public class CityViewModel : TreeViewItemViewModel { private City _city; private RelayCommand _testCommand; public CityViewModel(City city, CountryViewModel countryViewModel):base(countryViewModel,false) { _city = city; } Properties etc...... public ICommand TestCommand { get { if(_testCommand==null) { _testCommand = new RelayCommand(param => GetTestCommand(), param => CanCallTestCommand); ; } return _testCommand; } } protected bool CanCallTestCommand { get { return true; } } private static void GetTestCommand() { MessageBox.Show("It works"); } } ZAML <DockPanel> <DockPanel LastChildFill="True"> <Label DockPanel.Dock="top" Content="Title " HorizontalAlignment="Center"></Label> <StatusBar DockPanel.Dock="Bottom"> <StatusBarItem Content="Status Bar" ></StatusBarItem> </StatusBar> <Grid DockPanel.Dock="Top"> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="2*"/> </Grid.ColumnDefinitions> <TreeView Name="tree" ItemsSource="{Binding Continents}"> <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsExpanded" Value="{Binding IsExpanded,Mode=TwoWay}"/> <Setter Property="IsSelected" Value="{Binding IsSelected,Mode=TwoWay}"/> <Setter Property="FontWeight" Value="Normal"/> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="FontWeight" Value="Bold"></Setter> </Trigger> </Style.Triggers> </Style> </TreeView.ItemContainerStyle> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type ViewModels:ContinentViewModel}" ItemsSource="{Binding Children}"> <StackPanel Orientation="Horizontal"> <Image Width="16" Height="16" Margin="3,0" Source="Images\Continent.png"/> <TextBlock Text="{Binding ContinentName}"/> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type ViewModels:CountryViewModel}" ItemsSource="{Binding Children}"> <StackPanel Orientation="Horizontal"> <Image Width="16" Height="16" Margin="3,0" Source="Images\Country.png"/> <TextBlock Text="{Binding CountryName}"/> </StackPanel> </HierarchicalDataTemplate> <DataTemplate DataType="{x:Type ViewModels:CityViewModel}" > <StackPanel Orientation="Horizontal"> <Image Width="16" Height="16" Margin="3,0" Source="Images\City.png"/> <TextBlock Text="{Binding CityName}"/> </StackPanel> </DataTemplate> </TreeView.Resources> </TreeView> <GridSplitter Grid.Row="0" Grid.Column="1" Background="LightGray" Width="5" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/> <Grid Grid.Column="2" Margin="5" > <TabControl> <TabItem Header="Demo"> <DockPanel LastChildFill="True"> <ToolBar DockPanel.Dock="Top"> <!-- DOES NOT WORK--> <Button Name="btnTest" Command="{Binding TestCommand}" Content="Press me see if works"></Button> </ToolBar> <TextBox></TextBox> </DockPanel> </TabItem> <TabItem Header="Details" DataContext="{Binding Path=SelectedItem.City, ElementName=tree, Mode=OneWay}"> <StackPanel > <TextBlock VerticalAlignment="Center" FontSize="12" Text="{Binding CityName}"/> <TextBlock VerticalAlignment="Center" FontSize="12" Text="{Binding Area}"/> <TextBlock VerticalAlignment="Center" FontSize="12" Text="{Binding Population}"/> <TextBlock VerticalAlignment="Center" FontSize="12" Text="{Binding CityDetailsInfo.ClubsCount}"/> <TextBlock VerticalAlignment="Center" FontSize="12" Text="{Binding CityDetailsInfo.PubsCount}"/> </StackPanel> </TabItem> </TabControl> </Grid> </Grid> </DockPanel> </DockPanel>

  • Javascript incapable of getting element's max-height via element.style.maxHeight

    - by Zane
    I am making a simple accordion menu in javascript. I'd like to be able to set the compact and expanded heights for the elements via the css max-height and min-height values. For some reason, when I try to retrieve the min-height and max-height of the elements in javascript for animation purposes, I get an empty string rather than, for instance, "500px" like it should. The max-height value is set in css, e.g. #id { min-height: 40px; max-height: 500px; } is all set up, but when I put a debugging mechanism in my javascript such as alert( item.style.minHeight ); it pops up an empty alert box. This happens in Firefox 3.6.2 and IE 8. Does anybody know why javascript refuses to be able to get an element's minHeight and maxHeight?

  • ASP-style tags for Perl web development?

    - by Alex R
    I feel like I'm traveling 10 years back in time by asking this, but... Are there any modules, patches, or any "new" version of Perl (released in the last 10 years) to enable writing web-oriented Perl scripts using ASP-style tags? e.g. from ASP/JSP some html <% some code %> more HTML e.g. from PHP some html <? some code ?> more HTML Please don't worry about "why" I'm asking this... It's related to programming language research.

  • PySide using Style Sheets to change QtoolBox

    - by efi_ex
    I'm Wondering if somebody knows a better reference than the QT one for style sheets. I try to change the background of the content from a QToolBox but background-color only changes the header of the toolbox and the background of the content it reveals is left in a standard color. I then tried to change the bg of QWidget which worked but left me with problems now at Radiobuttons and Checkboxes, i also think changing QWidget isn't a good solution. The first picture is with Qt standard colors (this is a maya tool) the second when i change QWidget http://i.imgur.com/MNlSedx.png?1 http://i.imgur.com/wuplpmw.png?1

  • ProgressBar not updating on change to Maximum through binding

    - by Tom
    <ProgressBar Foreground="Red" Background="Transparent" Value="{Binding NumFailed, Mode=OneWay}" Minimum="0" Maximum="{Binding NumTubes, Mode=OneWay, Converter={x:Static wpftools:DebuggingConverter.Instance}, ConverterParameter=Failedprogressbar}" FlowDirection="RightToLeft" Style="{DynamicResource {x:Static wpftools:CustomResources.StyleProgressBarVistaKey}}" /> This is what my progressbar looks like at the moment. The style came from http://mattserbinski.com/blog/look-and-feel-progressbar and the DebuggingConverter is a no-op converter that prints the value, type and parameter to the Console. I have verified that the converter for the Maximum is being called when my NumTubes property is changed. Basically, the ProgressBar won't redraw until the Value changes. So, if I have 2 tubes and 1 is failed, even if I add 20 more tubes, the bar is still half filled until the NumFailed changes, then the proportion is updated. I've tried adding spurious notifications of the NumFailed property, but that apparently doesn't work since the value didn't change. Ideas?

  • Change background color of disabled listbox in windows classic theme

    - by Mercury821
    I am developing a WPF application that must run using Windows Classic theme. The application creates a dialog box containing a ListBox. When the dialog box is shown, it must be disabled for 1s before accepting any input. I am accomplishing this with a style trigger, and it works. However, the ListBox shows a white background when it's disabled, which I can't seem to get rid of. When using the aero theme, the following style resource fixes the issue: <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent"/> But when using Windows Classic theme, the white background reappears. How can i remedy the situation for Classic theme???
