  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice. But if i select any other cell in the row except the one containing the checkbox the purpose is solved. HERE IS MY CODE : public class TableSelectionTest extends JFrame implements ListSelectionListener { private final int COLUMN_COUNT = 5; private TblModel model; public TableSelectionTest() { initialize(); setDefaultCloseOperation(EXIT_ON_CLOSE); pack(); } private void initialize() { List data = new ArrayList(); for (int i = 0; i < 10; i++) { Object record[] = new Object[COLUMN_COUNT]; record[0] = Boolean.FALSE; for (int j = 1; j < COLUMN_COUNT; j++) { record[j] = new Integer(j); } data.add(record); } model = new TblModel(data); JTable table = new JTable(model); table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); table.getSelectionModel().addListSelectionListener (this); JScrollPane scroll = new JScrollPane(table); getContentPane().add(scroll, BorderLayout.CENTER); } public static void main(String[] args) { TableSelectionTest f = new TableSelectionTest(); f.show(); } class TblModel extends AbstractTableModel { private List data; public TblModel(List data) { this.data = data; } public int getColumnCount() { return COLUMN_COUNT; } public int getRowCount() { return data == null ? 0 : data.size(); } public void setValueAt(Object value, int rowIndex, int columnIndex) { getRecord(rowIndex)[columnIndex] = value; super.fireTableCellUpdated(rowIndex, columnIndex); } public Object getValueAt(int rowIndex, int columnIndex) { return getRecord(rowIndex)[columnIndex]; } public boolean isCellEditable(int rowIndex, int columnIndex) { if(columnIndex == 0) return true; else return false; } public Class getColumnClass(int columnIndex) { if (data == null || data.size() == 0) { return Object.class; } Object o = getValueAt(0, columnIndex); return o == null ? Object.class : o.getClass(); } private Object[] getRecord(int rowIndex) { return (Object[]) data.get(rowIndex); } } public void valueChanged(ListSelectionEvent e) { if (!e.getValueIsAdjusting()) { ListSelectionModel lsm = (ListSelectionModel) e.getSource(); int index = lsm.getMinSelectionIndex(); if(model.getRecord(index)[0] == Boolean.FALSE) model.setValueAt(Boolean.TRUE, index, 0); else if(model.getRecord(index)[0] == Boolean.TRUE) model.setValueAt(Boolean.FALSE, index, 0); } } } Please reply soon as it is bugging me a lot Thank you in advance :)

  • Loading Views dynamically

    - by Dann
    Case 1: I have created View-based sample application and tried execute below code. When I press on "Job List" button it should load another view having "Back Btn" on it. In test function, if I use [self.navigationController pushViewController:jbc animated:YES]; nothing gets loaded, but if I use [self presentModalViewController:jbc animated:YES]; it loads another view haveing "Back Btn" on it. Case 2: I did create another Navigation Based Applicaton and used [self.navigationController pushViewController:jbc animated:YES]; it worked as I wanted. Can someone please explain why it was not working in Case 1. Does it has something to do with type of project that is selected? @interface MWViewController : UIViewController { } -(void) test; @end @interface JobViewCtrl : UIViewController { } @end @implementation MWViewController (void)viewDidLoad { UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Job List!" forState:UIControlStateNormal]; [btn addTarget:self action:@selector(test) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:btn]; [super viewDidLoad]; } -(void) test { JobViewCtrl* jbc = [[JobViewCtrl alloc] init]; [self.navigationController pushViewController:jbc animated:YES]; //[self presentModalViewController:jbc animated:YES]; [jbc release]; } (void)dealloc { [super dealloc]; } @end @implementation JobViewCtrl -(void) loadView { self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.view.backgroundColor = [UIColor grayColor]; UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Back Btn!" forState:UIControlStateNormal]; [self.view addSubview:btn]; } @end

  • How do I view the full content of a text or varchar(MAX) column in SQL Server 2008 Management Studio

    - by adamjford
    In this live SQL Server 2008 (build 10.0.1600) database, there's an Events table, which contains a text column named Details. (Yes, I realize this should actually be a varchar(MAX) column, but whoever set this database up did not do it that way.) This column contains very large logs of exceptions and associated JSON data that I'm trying to access through SQL Server Management Studio, but whenever I copy the results from the grid to a text editor, it truncates it at 43679 characters. I've read on various locations on the Internet that you can set your Maximum Characters Retrieved for XML Data in Tools > Options > Query Results > SQL Server > Results To Grid to Unlimited, and then perform a query such as this: select Convert(xml, Details) from Events where EventID = 13920 (Note that the data is column is not XML at all. CONVERTing the column to XML is merely a workaround I found from Googling that someone else has used to get around the limit SSMS has from retrieving data from a text or varchar(MAX) column.) However, after setting the option above, running the query, and clicking on the link in the result, I still get the following error: Unable to show XML. The following error happened: Unexpected end of file has occurred. Line 5, position 220160. One solution is to increase the number of characters retrieved from the server for XML data. To change this setting, on the Tools menu, click Options. So, any idea on how to access this data? Would converting the column to varchar(MAX) fix my woes?

  • How do I remove a button from a view controller's toolbar on the iPhone?

    - by Tony
    I have code that works great for adding a button to the toolbar: NSArray* toolbarItems = [NSArray arrayWithObjects:flexibleSpace,shuffleBarItem,flexibleSpace,nil]; self.toolbarItems = toolbarItems; However, I also want to be able to remove toolbar items. When I use the below method, my application crashes: NSArray* toolbarItems = [NSArray arrayWithObjects:flexibleSpace,nil]; self.toolbarItems = toolbarItems; Does anyone know how I can dynamically alter the toolbar on the iPhone? Thanks!

  • How do you populate a UIImage view with ASIHTTPRequest given @2x?

    - by Jonathan Page
    I've been trying to load images from a url using ASIHTTPRequest but I always come up with a blank UIImage. I think it might have something to do with iOS automatically choosing the @2x named version of images or vica versa. [ASIHTTPRequest setDefaultCache:[ASIDownloadCache sharedCache]]; NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]]; NSURL *url = [NSURL URLWithString:url_string]; __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request setDownloadCache:[ASIDownloadCache sharedCache]]; [request setCachePolicy:ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy]; [request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy]; [request setSecondsToCache:86400]; [request setDelegate:self]; [request setCompletionBlock:^{ NSLog(@"Successful Update"); [self makeAssignment]; }]; [request setFailedBlock:^{ NSError *error = [request error]; NSLog(@"%@", [error localizedDescription]); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Update Failed" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; }]; [request startAsynchronous]; NSLog(@"%@", url_string); The makeAssignment method is below. NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]]; NSURL *url = [NSURL URLWithString:url_string]; downloadedImage = [[UIImage alloc] initWithContentsOfFile:[[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]]; NSLog(@"%@", downloadedImage); NSLog(@"%@", [[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]); Nothing I do, including naming images @2x on the server or providing both versions, gets it to load. Any ideas? Has anyone done this before? When I load them locally (from within the package) I don't have any issues. Thanks!

  • MSSQL: Views that use SELECT * need to be recreated if the underlying table changes

    - by cbp
    Is there a way to make views that use SELECT * stay in sync with the underlying table. What I have discovered is that if changes are made to the underlying table, from which all columns are to be selected, the view needs to be 'recreated'. This can be achieved simly by running an ALTER VIEW statement. However this can lead to some pretty dangerous situations. If you forgot to recreate the view, it will not be returning the correct data. In fact it can be returning seriously messed up data - with the names of the columns all wrong and out of order. Nothing will pick up that the view is wrong unless you happened to have it covered by a test, or a data integrity check fails. For example, Red Gate SQL Compare doesn't pick up the fact that the view needs to be recreated. To replicate the problem, try these statements: CREATE TABLE Foobar (Bar varchar(20)) CREATE VIEW v_Foobar AS SELECT * FROM Foobar INSERT INTO Foobar (Bar) VALUES ('Hi there') SELECT * FROM v_Foobar ALTER TABLE Foobar ADD Baz varchar(20) SELECT * FROM v_Foobar DROP VIEW v_Foobar DROP TABLE Foobar I am tempted to stop using SELECT * in views, which will be a PITA. Is there a setting somewhere perhaps that could fix this behaviour?

I currently got something like this in the controller I push (that i want to be fullscreen) : - (void)viewDidLoad { [super viewDidLoad]; self.view.autoresizingMask = 0; self.view.superview.autoresizingMask = 0; [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackTranslucent]; //[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; [self.navigationController.navigationBar setBarStyle:UIBarStyleBlackTranslucent]; CGRect test = CGRectMake(0.0,0.0,320,44); //[self.navigationController.navigationBar setFrame:test]; //[self setWantsFullScreenLayout:YES]; [self.view.superview setBounds:CGRectMake(0,-20.0,320,480)]; //[self.view setBounds:[[UIScreen mainScreen] bounds]]; [self.view setBounds:CGRectMake(0,-20.0,320,480)]; //CGRect rect4 = CGRectMake(0.0,0.0,320.0,500.0); //[self.view setFrame:rect4]; [self.view setBackgroundColor:[UIColor redColor]]; } As you can see I tried a lot of stuff :D but my red background isn't going under my status bar ... I am using the iphone simulator (in case it has to do with it ..) Thank you for any help ;) Gotye.

  • Setting acquired location to a text view: How to maintain?

    - by Mark
    Hi, I have built an app for the Motorola Droid which should automatically update a server with the phone's location. After the user performs a particular task on the main activity screen, an alarm is set to update the user's location periodically, using a service. The alarm is explicitly stopped when the user completes another task. Thing is, I have set up a location manager within the main activity's onCreate() method which is supposed to place the first acquired lat/long into two textview fields. Even though the manifest is set up for acquiring coarse and fine coords and I'm using requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener), with minTime and minDistance set to zero, I'm not seeing the coords coming up on the screen. With that, I'm not recording any locations on the server. When I seed the textviews with sample coords, they are being recorded fine on the server. I am not at a computer that can run the IDE, so don't currently have the code, but am desperate for some help on this. One other thing is that the main activity screen calls a photography app before the user manually clicks "send data". I'm suspicious that I may need to override the main activity's onResume() method to do this location acquisition. Please help, thanks. Mark.

  • ASP.NET MVC jQuery: Shoud we be concerned about a lot of jQuery/javascript on a View?

    - by Mark Redman
    We are moving from WebForms to MVC and and using a lot of jQuery. I appears we have a lot of jQuery/JavaScript in our Views, is this common and are there any concerns about security. The obvious step is to refactor into plugins and more generic UserControls etc, but this jQuery would still be "visible" by looking at js files etc. We are validating everything on the server-side anyway but should we be concerned?

  • UIButton stops responding after going into landscape mode - iPhone

    - by casey
    I've been trying different things the last few days and I've run out of ideas so I'm looking for help. The situation is that I'm displaying my in-app purchasing store view after the user clicks a button. Button pressed, view is displayed. The store shows fine. Inside this view, I have a few labels with descriptions of the product, and then below them I have the price and a Buy button which triggers the in-app purchase. Problem is when I rotate the phone to landscape, that Buy button no longer responds, weird. Works fine in portrait. The behavior in landscape when the I touch the button is nothing. It doesn't appear to press down and be selected or anything, just not responding to my touches. But then when I rotate back to portrait or even upside down portrait, it works fine. Here is the rough structure of my view in IB, all the rotating and layout is setup in IB. I set the autoresizing in IB so that everything looks ok in landscape and the Buy button expands horizontally a little bit. The only layout manipulation I do in my code is after loading, I set the content size of the scroll view. File Owner with view set to the scrollView / scrollView ----/ view --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ uibutton (Buy) After orientation changes I printed out the userInteractionEnabled property of the scrollView and the button, and they were both TRUE at all orientations. Ideas? Or maybe some other way of displaying a buy button that won't be nonfunctional? I've already begun a branch that plays with a toolbar and placing the buy button there, but I can't seem to get the bar to stay in place while scrolling.

  • Can I view a list of public variables of some Adobe Air app or web flash file from another app?

    - by Parris
    I was thinking about creating making AIM pluggin that checks pandora one (desktop) or pandora website periodically to see what is currently playing and update a user's status. I suppose the main question is there a clever way to access a "public" variable from some open Adobe Air process? I KNOW this sounds like some crazy security flaw, but it may also be a feature. I am pretty sure javascript can potentially handle it. Thanks!

  • How can I reduce the number of loops in this VIEW in Rails when using :collection?

    - by Angela
    I am using the :collection to go through all the Contacts that are part of a given Campaign. But within that Campaign I check for three different Models (each with their own partial). Feels like I am going through the list of Contacts 3x. How can I make this alot leaner? <h2>These are past due:</h2> <% @campaigns.each do |campaign| %> <h3>Campaign: <%= link_to campaign.name, campaign %></h3> <strong>Emails in this Campaign:</strong> <% for email in campaign.emails %> <h4><%= link_to email.title, email %> <%= email.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_email", :collection => @contacts, :locals => {:email => email} %> <% end %> Calls in this Campaign: <% for call in campaign.calls %> <h4><%= link_to call.title, call %> <%= call.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_call", :collection => @contacts, :locals => {:call => call} %> <% end %> Letters in this Campaign: <% for letter in campaign.letters %> <h4><%= link_to letter.title, letter %> <%= letter.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_letter", :collection => @contacts, :locals => {:letter => letter} %> <% end %> <% end %>

  • android custom dialog imageButton onclicklistener

    this is my custom dialog class: package com.WhosAround.Dialogs; import com.WhosAround.AppVariables; import com.WhosAround.R; import com.WhosAround.AsyncTasks.LoadUserStatus; import com.WhosAround.Facebook.FacebookUser; import android.app.Dialog; import android.content.Context; import android.graphics.drawable.Drawable; import android.view.MotionEvent; import android.view.View; import android.widget.ImageButton; import android.widget.ImageView; import android.widget.TextView; public class MenuFriend extends Dialog{ private FacebookUser friend; private AppVariables app; public MenuFriend(Context context, FacebookUser friend) { super(context, android.R.style.Theme_Translucent_NoTitleBar); this.app = (AppVariables) context.getApplicationContext(); this.friend = friend; } public void setDialog(String userName, Drawable userProfilePicture) { setContentView(R.layout.menu_friend); setCancelable(true); setCanceledOnTouchOutside(true); TextView name = (TextView) findViewById(R.id.menu_user_name); TextView status = (TextView) findViewById(R.id.menu_user_status); ImageView profilePicture = (ImageView) findViewById(R.id.menu_profile_picture); ImageButton closeButton = (ImageButton) findViewById(R.id.menu_close); name.setText(userName); profilePicture.setImageDrawable(userProfilePicture); if (friend.getStatus() != null) status.setText(friend.getStatus()); else new LoadUserStatus(app, friend, status).execute(0); closeButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { dismiss(); } }) } } for some reason eclipse tells me the following errors on closeButton imageButton: The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (new DialogInterface.OnClickListener(){}) The type new DialogInterface.OnClickListener(){} must implement the inherited abstract method DialogInterface.OnClickListener.onClick(DialogInterface, int) The method onClick(View) of type new DialogInterface.OnClickListener(){} must override or implement a supertype method why is that ?

  • How do I view the CMake command line statement that Qt Creator executes?

    - by Evan
    I'm attempting to debug a command line CMake failure. The same CMake file works in Qt Creator, with the arguments in the Qt Creator window matching what I have entered on the command line. This makes me think Qt Creator is adding some extra arguments, which makes sense since the generator drop down has several options that specify architecture and CMake version. Is there a way to get the CMake command that Qt Creator executed to produce the desired result, specifically the arguments passed to the CMake executable? I found one post that talks about viewing the CMakeCache files to do some forensics, but this only proves there are differences, it doesn't quickly show me what arguments to change.

  • Subclassing ViewPager Breaks Animation

    - by Ryan Thomas
    In my Android application I have an activity which uses a view pager to display 4+ pages (Fragments). I implemented buttons on each screen that move between pages by calling: pager.setCurrentItem(position, true); The view pager and fragments are all working as I desired. I then began looking for a solution to disable user swiping between pages so that the transition between pages in handled by the buttons only. The solution I found was mentioned in a few stackoverflow articles as well as This Blog that suggest subclassing the view pager to intercept touch events to disable swiping. I followed those examples by subclassing the view pager class as follows: public class ViewPager extends android.support.v4.view.ViewPager { private boolean enabled; public ViewPager(Context context, AttributeSet attrs) { super(context, attrs); this.enabled = true; } @Override public boolean onTouchEvent(MotionEvent event) { if (this.enabled) { return super.onTouchEvent(event); } return false; } @Override public boolean onInterceptTouchEvent(MotionEvent event) { if (this.enabled) { return super.onInterceptTouchEvent(event); } return false; } public void setSwipingEnabled(boolean enabled) { this.enabled = enabled; } } Using the subclassed view pager and calling setSwipingEnabled(false) works as was desired. The user can no longer move between pages with swipe gestures and I can still move between pages via button clicks by calling setCurrentItem(int position, boolean smoothScroll). However using the subclass breaks the animation between pages. When I call setCurrentItem(position, true) with android.support.v4.view.ViewPager I get very clean scrolling animations between pages. When I make the same call using the subclass the screen has a very brief 'flash' and then automatically draws the new page. I would like to know how to fix the animation while retaining the ability to disable user swiping between pages. I greatly appreciate any help with this. Let me know if you need any additional information. So far I have tested using a Samsung device running 2.3.5 and an AVD emulator targeting Android 2.3.3.

  • ios UITableView reloadData don't increase content height

    - by Zoltan Varadi
    I'm facing a strange error in my iOS app and haven't been able to figure out the reason why. In my UITableView i can add new cells, so i refresh the array that is the datasource and call reloadData. Everything works without error. The numberOfRowsInSection is called again, and it's value is one more than it's previous value was. The new cell even gets inserted at the bottom of the tableview, but i cant scroll down to it. I only know that it's there because the tableview bounces and i can see it. I'm guessing the tableview's content height is not getting increased for some reason, but i have no idea why. I'm using iOS 6 btw. Any help is very much appreciated! Thanks, Zoli EDIT, answers for Srikanth's questions: How is data getting added. There's an NSArray containing objects of a specific type. The array.count is the number of the number of cells. This NSArray gets its values from a database query. When you say, you are refreshing the array, what do you mean. By refreshing the array i mean i execute a new query in the database and put the results of this query into an NSArray. this will be the tableview's datasource array. Like this: dataSourceArray = [dbManager executeQuery]; [tableView reloadData]; Are you adding the data within the same view controller Yes. Can you show some code as to what you are doing See above. Is the table view at the root of the view controllers view or is it within another view The tableview is the main view's first child. Can you try adding data to the array at the beginning, so that you can view the cell being added at the top. I don't understand what you mean.

  • Resizing a UIView - expanding the top

    - by Mongus Pong
    I have a UIView inside of a UIScrollView that I want to resize. I can increase the height easily by : CGRect frame = self.drawinView.frame; frame.size.height += 100; self.drawinView.frame = frame; self.drawinScrollView.contentSize = CGSizeMake(frame.size.width, frame.size.height); And all is good. The above code will create a new area of the view at the bottom of the view that I can fill out. Now when I resize the view, I only want to be repainting the new portion of the view that has just been created. I dont want to have to repaint the whole view. However! I have run into difficulty when I need to expand the top of the view. Doing : CGRect frame = self.drawinView.frame; frame.origin.y -= 100; self.drawinView.frame = frame; self.drawinScrollView.contentSize = CGSizeMake(500, 600); does not work. How can I do this without having to repaint the entire view?
