  • Android accessibility focus - clicking a view changes focus to previous view

    - by benkdev
    I'm using android TalkBack to test my application for accessibility use. When I swipe to select a view and double tap, the focus returns the the view above it. Usually when swiping to a view and double clicking it, onClick is called. What am I doing wrong? <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/all_white" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/header" android:scaleType="center" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/green_bar" android:scaleType="center" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/blue_bar" android:scaleType="center" /> <EditText android:id="@+id/username" android:layout_width="325dp" android:layout_height="wrap_content" android:hint="@string/username" android:focusable="true" android:nextFocusDown="@id/password" /> <EditText android:id="@+id/password" android:inputType="textPassword" android:layout_width="325dp" android:layout_height="wrap_content" android:hint="@string/password" android:focusable="true" android:nextFocusUp="@id/username" android:nextFocusDown="@id/login" /> <Button android:id="@+id/login" android:onClick="doLogin" android:focusable="true" android:layout_width="325dp" android:layout_height="wrap_content" android:text="@string/login" android:nextFocusUp="@id/password" android:nextFocusDown="@id/create_trial_account" /> <Button android:id="@+id/create_trial_account" android:layout_width="100dip" android:layout_height="wrap_content" android:text="@string/new_user" android:onClick="createAccount" android:focusable="true" android:nextFocusUp="@id/login" /> <TextView android:id="@+id/copyright" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/copyright" /> <TextView android:id="@+id/buildNumber" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout>

  • How do I pass arguments to pages in a WPF application?

    - by Rod
    I'm working on upgrading a really old VB6 app to a WPF application. This will be a page-based app, but not a XBAP. The old VB6 app had a start form where a user would enter search criteria. Then they would get results in a grid, select a row in the grid and then click on one of 3 buttons. I am thinking that what I'll do is use hyperlink controls on the WPF app. No matter what button the user clicked on the old VB6 app, it would go to a second form. What it did on the second form was dependent upon which button the user clicked on the first form. So, I want the first page in my WPF app to do the same thing, but depending upon which hyperlink they click on will dictate what happens on the second page. They will either (a) go to the second page to edit the details as well as a lot more information, related to what they selected on the first page, or (b) enter a new record and all associated data (a new client, in this case), or (c) create a new case for the same client, selected on the first page. For me the hard thing is I don't know how to pass that information along to the second page. Is there something in WPF like in HTML where there's a query string? Or how do you get information from the first page to the second page, in WPF? I'm working in VS 2008.

  • can't properly shutdown ubuntu and sound problem on HP mini 311 netbook

    - by Viele
    hi, I recently bought a HP mini 311 netbook. I replaced its harddrive and installed ubuntu 10.04. Since then, I have encountered some very strange problem with its sound and shutdown/reboot. At times, when I start the computer, it will have no sound, on the GUI the sound is at max, but no sound is available. This sometimes also happen after after upgrades, hibernate, and toggling the wireless radio button. Strangely, when the sound is out the device will also refuse to be shutdown. If I shutdown the computer using the GUI, it will simply go back to the log in screen without actually shutting down. If I use "sudo shutdown 0", the computer will hang on the loading screen of the shut down process. I had to force the pc to shutdown by holding the power button down. usually (probably always) after I force a turn-off then start off again. the sound and shutdown become normal. I wonder if anyone have clues regarding to the cause of this problem. This the info about the computer: 1) installed ubuntu 10.04LTS RC, later upgraded to formal released version. 2) cat /proc/asound/version == "Advanced Linux Sound Architecture Driver Version 1.0.21." however, when doing 'alsaconf' the version displayed is 1.0.23 any help is appreciated. Thanks

  • ASP.Net ListView and event handling.

    - by Neil
    I have an .ascx which contains a listview. Let's call it the parent. Within its ItemTemplate I reference a second .ascx which is basically another listview, let's call it the child. On the parent, the child control is wrapped in a placeholder tag. I use this place holder tag to show and hide the child. Psuedo code: The child listview has a 'close' button in its Layout Template. Let's call it "btnClose" with an onClick event of "btnClose_Click". I want to use this button to set the visibility of the containing placeholder. I'm trying to avoid doing something like using PlaceHolder plhChild = (PlaceHolder)childListCtl.NamingContainer since I can't guarantee every instance of the child .ascx will be contained within a placeholder. I tried creating an event in the child that could be subscribed to. Psuedo code: public delegate CloseButtonHandler(); public event CloseButtonHandler CloseButtonEvent; And in the actual btnClose_Click(Object sender, EventArgs e) event I have: if (CloseButtonEvent != null) CloseButtonEvent(); My problem is that the delegate CloseButtonEvent is always null. I've tried assigning the delegate in the listview's OnDatabound event of the parent and on the click event, to set the plhChild.visible = true, and I've stepped through the code and know the delegate instantiation works in both place, but again, when it gets to the btnClose_Click event on the child, the delegate is null. Any help would be appreciated. Neil

  • Why do .NET winforms scale improperly at large DPI settings?

    - by Alex
    My .NET application (VB.NET 3.5 if you really must know) forms do not properly format when rendered at high DPI settings. All of the fixes I've found so far simply explain the cause of the problem as "certain UI elements do not scale properly". I was wondering if anyone had a more meaningful explanation? Thanks!

  • mysql database normalization question

    - by Chocho
    here is my 3 tables: table 1 -- stores user information and it has unique data table 2 -- stores place category such as, toronto, ny, london, etc hence this is is also unique table 3 -- has duplicate information. it stores all the places a user have been. the 3 tables are linked or joined by these ids: table 1 has an "table1_id" table 2 has an "table2_id" and "place_name" table 3 has an "table3_id", "table1_id", "place_name" i have an interface where an admin sees all users. beside a user is "edit" button. clicking on that edit button allows you to edit a specific user in a form fields which has a multiple drop down box for "places". if an admin edits a user and add 1 "places" for the user, i insert that information using php. if the admin decides to deselect that 1 "places" do i delete it or mark it as on and off? how about if the admin decides to select 2 "places" for the user; change the first "places" and add an additional "places". will my table just keep growing and will i have just redundant information? thanks.

  • Cocoa Core data: cannot save Created Items in NSTableview

    - by Paul Rostorp
    Hello, I'm am a beginner in mac os x development and am trying to get started with all this. Here is my problem : I've create a non-document based cocoa app using core data as storage. I've added an entity and attributes to the xdatamodel. In IB i've created an NSArrayController and linked it properly. I've created an nstableview binded to the nsarraycontroller. Next I added a button linked to nsarraycontroller with the " add: " method. When I try it out, I can add and edit the items in the table. Here comes the problem: Core data is supposed to save everything automatically, but to make sure i linked the "save" button in the menu to the appdelegate and to the " file's owner" , first responder, application... everything possible ( with both " save :" and " saveaction:" methods ). And still it doesn't save when clicking save: when I restart the cell created ( and renamed ) are gone. And also, I didn't even edit the source code yet; core data for such simple tasks is supposed to only need Interface builder. Please help me for this, I haven't found any threads resolving this problem. Thank you in advance.

  • WPF toolbar disappearing on resize

    - by user1122909
    On my main form I have a toolbar with a number of buttons. Once the parent form is resized down by dragging it so that the entire toolbar with all its buttons no longer fits in the width of the window, the whole toolbar disappears. Is there a way I can make it so that as you resize it, when you get to the width of the toolbar the inner controls of the form stop resizing and stay displayed, just cut off where the window has resized to? Code is <Grid > <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <ToolBar Grid.Row="1" Height="50" Name="tbMainToolbar" VerticalAlignment="Top" MinWidth="900" > <ToolBar.Background> <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"> <GradientStop Color="White" Offset="0.0" /> <GradientStop Color="#DCEBFF" Offset="0.25" /> <GradientStop Color="#99CCFF" Offset="0.75" /> <GradientStop Color="#99CCFF" Offset="1.0" /> </LinearGradientBrush> </ToolBar.Background> <DockPanel LastChildFill="True"> <Button Name="btnApproved" DockPanel.Dock="Left" Click="btnToolbar_Click" CommandParameter="APPROVED" Style="{StaticResource ToolbarButtonDisplay}" HelperClasses:ButtonProperties.Image="..\..\Resources\Images\APPROVEU.GIF" Content="Approve"> </Button> ... and so forth for about 20 buttons

  • How to make a model instance read-only after saving it once?

    - by Ryszard Szopa
    One of the functionalities in a Django project I am writing is sending a newsletter. I have a model, Newsletter and a function, send_newsletter, which I have registered to listen to Newsletter's post_save signal. When the newsletter object is saved via the admin interface, send_newsletter checks if created is True, and if yes it actually sends the mail. However, it doesn't make much sense to edit a newsletter that has already been sent, for the obvious reasons. Is there a way of making the Newsletter object read-only once it has been saved? Edit: I know I can override the save method of the object to raise an error or do nothin if the object existed. However, I don't see the point of doing that. As for the former, I don't know where to catch that error and how to communicate the user the fact that the object wasn't saved. As for the latter, giving the user false feedback (the admin interface saying that the save succeded) doesn't seem like a Good Thing. What I really want is allow the user to use the Admin interface to write the newsletter and send it, and then browse the newsletters that have already been sent. I would like the admin interface to show the data for sent newsletters in an non-editable input box, without the "Save" button. Alternatively I would like the "Save" button to be inactive.

  • Fork or copy a users browser session in IE

    - by jmoeller
    Is it possible to fork a users session (or do something similar) in a Internet Explorer plugin? I want to process the page the user is on when they click a button in the toolbar. To avoid interrupting the users browsing, I'd like to "copy" everything so I can parse and process the page in the background. The processing can involve things such as loading the content of the result links on a Google search, if that's where the button was clicked. So - what I basically want is to imitate "Ctrl+N" but hide the window from the user, so they won't be interrupted. As you can see, if you fill out and submit the form on http://www.snee.com/xml/crud/posttest.html and press "Ctrl+N", everything posted will still appear in the new window, but it won't post the data twice. I was thinking of somehow copying the IWebBrowser2, but: I'm not sure if that's possible (I haven't been able to find any information on MSDN) I don't know if it copies the sessions as well. Creating a new instance of the IWebBrowser2 and simply navigating to the current URL isn't a valid solution as POST-variables of course doesn't get carried over.

  • Constant error in compiler using C#'s provided objects

    - by dotnetdev
    I have used the built in C# methods to write a compiler, like the following: CodeDomProvider codeProvider = CodeDomProvider.CreateProvider("CSharp"); string Output = "Out.exe"; Button ButtonObject = (Button)sender; this.RadTextBox1.Text = string.Empty; System.CodeDom.Compiler.CompilerParameters parameters = new CompilerParameters(); //Make sure we generate an EXE, not a DLL parameters.GenerateExecutable = true; parameters.OutputAssembly = Output; CompilerResults results = codeProvider.CompileAssemblyFromSource(parameters, RadTextBox1.Text); if (results.Errors.Count > 0) { RadTextBox2.ForeColor = Color.Red; foreach (CompilerError CompErr in results.Errors) { RadTextBox2.Text = RadTextBox2.Text + "Line number " + CompErr.Line + ", Error Number: " + CompErr.ErrorNumber + ", '" + CompErr.ErrorText + ";" + Environment.NewLine + Environment.NewLine; } } else { //Successful Compile RadTextBox2.ForeColor = Color.Blue; Guid guid = Guid.NewGuid(); string PathToExe = Server.MapPath(Path.Combine(@"\Compiled" , Output)); FileStream fs = System.IO.File.Create(PathToExe); using (StreamWriter sw = new StreamWriter(fs)) { sw.Write(RadTextBox1.Text); } Response.WriteFile(PathToExe); When I run this code and write a Main method (such as the code sample in http://msdn.microsoft.com/en-us/library/ms228506(VS.80).aspx, I get this error: Line number 0, Error Number: CS5001, 'Program 'c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Out.exe' does not contain a static 'Main' method suitable for an entry point; The code above is used as the basis of a compiler on my site (not yet live). So you type in code and generate an .exe assembly. But when I enter code into the textbox for code writing (Radtextbox1), even with a main method, I get the error. What gives? Thanks

  • JScrollPane Scrolls Down with Long Text in JEditorPane

    - by Jim
    Hello, I want to have a JEditorPane inside a JScrollPane. When the user clicks a button, the click listener will create a textEditor, call jscrollpane.setViewPort(textEditor), call textEditor.setText(String) to fill it with editable text, and call jscrollpane.getVerticalScrollBar().setValue(0). In case you're wondering, yes, the setText() must come after the setViewPort() for reasons that aren't on topic. Here is the problem: After the user clicks the button, the JScrollPane's view scrolls all the way to the bottom. I want the scrollbar to be at the top, as per the last line in my click listener. I popped open a debugger, and to my horror, discovered that the jscrollpane's viewport is being forced down to the bottom after the conclusion of the click listener (when pumping filters). It appears that Swing is delaying the population of the editor/jscrollpane until after the conclusion of the clicklistener, but is calling the scrollbar command first. Thus, the undesired behavior. Anyway, I'm wondering if there is a clean solution. It seems that wanting a scrollpane to be scrolled to the top after modification would be a reasonably common requirement, so I'm assuming this is a well-solved problem. Thanks!
