    - by Samuel
    I have a form validation message for the user name field which says the following Name can only contain alphabets, '.' and ' ' characters OR should it be Name can only contain alphabets, dot and space characters OR should it be Name can only contain alphabets, dot (".") and space (" ") characters Which is preferable from a usability perspective assuming the end users has very less exposure to computers.

  • iOS User guidelines at startup

    - by user963737
    I was wondering is there a way to give the user a small guided tour of the app with small pops exactly above the UI elements indicating what it will do and not using the standard popups which iOS has. Something like if an icon is used to post status there should be a small pop up on top of it which tells us it is used to post status and can be closed a standard in in games to introduce the player to their UI.

  • Custom UITableViewCell from xib isn't displaying properly

    - by Kenny Wyland
    I've created custom UITableCells a bunch of times and I've never run into this problem, so I'm hoping you can help me find the thing I've missed or messed up. When I run my app, the cells in my table view appear to be standard cells with Default style. I have SettingsTableCell which is a subclass of UITableViewCell. I have a SettingsTableCell.xib which contains a UITableViewCell and inside that are a couple labels and a textfield. I've set the class type in the xib to be SettingsTableCell and the File's Owner of the xib to my table controller. My SettingsTableController has an IBOutlet property named tableCell. My cellForRowAtIndexPath contains the following code to load my table view xib and assign it to my table controller's tableCell property: static NSString *CellIdentifier = @"CellSettings"; SettingsTableCell *cell = (SettingsTableCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"SettingsTableCell" owner:self options:nil]; cell = self.tableCell; self.tableCell = nil; NSLog(@"cell=%@", cell); } This is what my xib set up looks like in IB: When I run my app, the table displays as if all of the cells are standard Default style cells though: The seriously weird part is though... if I tap on the area of the cell where the textfield SHOULD be, the keyboard does come up! The textfield isn't visible, there's no cursor or anything like that... but it does respond. The visible UILabel is obviously not the UILabel from my xib though because the label in my xib is right justified and the one showing in the app is left justified. I'm incredibly confused about how this is happening. Any help is appreciated.

  • How to column-ify an output from a certain program?

    - by mbaitoff
    I have a program that generates and outputs a sequence of simple sample math homework tasks, like: 1 + 1 = ... 3 + 3 = ... 2 + 5 = ... 3 + 7 = ... 4 + 2 = ... a sequence can be quite long, and I'd like to save space when this sequence is printed by converting it as follows: 1 + 1 = ... 3 + 7 = ... 3 + 3 = ... 4 + 2 = ... 2 + 5 = ... that is, wrapping the lines into the two or more columns. I was expecting the column linux utility to do the job using the -c N option witn N=2, however, it still outputs the lines in one column whatever the N is. How would I do the column-ifying of the sequence of lines?

  • How to set UITableView to Grouped?

    - by 4thSpace
    In an iPhone navigation based app, I want to add a second tableview but have its design available in IB. I've added a new empty XIB and dragged a UITableView onto it. I want to setup the layout through IB. I've created a controller for this tableview and set the File's Owner class in IB to this controller. I linked the tableview to File's Owner as well. I set the tableview to grouped in IB. However, that does not translate at runtime. I still have a plain tableview. In fact, none of the Inspector settings work at runtime. What have I missed?

  • UI Design Tips and Tutorials for Android

    - by Omega
    Does anyone have any good pointers on designing the UI for an android application and some good practises? Obviously I'm aware of the basic principles involved with designing the layout in XML. Also, that you have a stack of activities. But I'm interested in some approaches to creating the interfaces and also how to design an application around those intentions.

  • How do I send an email from my webpage?

    - by Jordan S
    I am not a web developer but I do have a lot of programming experience in C# and Windows forms programming. On our company webpage my boss wants me to put in a textbox where visitors can submit a comment and press a submit button and that comment will be sent to an email address. Right now, our website uses just plain old html, no php or javascript or anything like that. I am wondering what is the simplest way to accomplish what I need? Can someone point me in the right direction? The website is hosted on an Apache server so I won't be able to use aspx.

  • Saving results to a file in C++

    - by user1680877
    I have a problem with this code. What I am looking for in the code is to get the result of "first" and "second" randomly and put the result in a file. It works great if I run it without using the file and I get all the correct results, but when I try to save the result in the file, I get only the first node which contains (first, secnd). Here is the code: #include<iostream> #include <fstream> #include<cmath> using namespace std; void main() { int first[100],secnd[100]; for (int i=0; i<100 ;i++) { first[i]=rand()%500; //random number from to 499 secnd[i]=rand()%500; //random number from to 499 ofstream myfile; myfile.open ("example.txt"); myfile << "Writing this to a file.\n"; myfile <<first[i]<<" "<<secnd[i]; myfile.close(); } }

  • I have a problem implementing states in my Flex app, please help!

    - by ben
    Hey guys, I'm trying to work out how to use states in my Flex app. I've created two states, State1 and Stage 2. Both are based off the base state. I've created a few visual elements for State1, and given each of them includeIn="State1". But when I'm in design mode and click on State2, these elements are still visible? Why is that? If I try to delete them while State2 is selected, all that happens is RemoveChild is added to the State2 tag. Is this how I'm supposed to do it? Thanks for reading!

  • Detecting when a cell's detail-disclosure button has been clicked (when using a custom cell XIB)

    - by Gloria
    1 if (cell == nil) 2 { 3 [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; 4 cell = tvCell; 5 self.tvCell = nil; 6 } There's some code from an Apple example of using your own "custom cell XIB" to create cells in a UITableView. It appears to work... but I think I would do better to actually UNDERSTAND what is being done there. Why isn't line #3 assigning the value TO something? cell = [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; (In fact, cell and tvCell aren't being used at all.) Why is line #4 assigning using tvCell when nothing has been put it in at all, yet? Why is line #5 nulling out the tvCell that I need? Why is "@property (nonatomic, assign) IBOutlet UITableViewCell *tvCell;" using assign, not retain? About the only thing I can't get working correctly is when I put a disclosure-button on my custom cell XIB. Is there a way for me to detect when the user has clicked on it? (Hopefully, without using 100s of TAGs.)

  • How do I use the Microsoft VSTO interfaces?

    - by user557554
    hi, I would like to create an addin for microsoft outlook, and am using the visual studio tools to do so. However I am really struggling to get my head around the use of interfaces within the VSTO environment - the resources on MSDN show many useful looking interfaces, but I am unsure how to use these interfaces to access data. For example I am trying to add a new folder into an IMAP account but am finding it very difficult to work out how to get outlook to do so. Can anyone recommend any good resources for learning how to use VSTO (I have VSTO for dummies, but it doesn't cover the level of detail I need, I have been using MSDN, but I have found it doesnt offer much information on how to use the interfaces etc.) thanks.

  • Qt, can't display child widget

    - by Blin
    I have two widgets defined as follows class mainWindow : public QWidget { Q_OBJECT public: mainWindow(); void readConfig(); private: SWindow *config; QVector <QString> filePath; QVector <QLabel*> alias,procStatus; QVector <int> delay; QGridLayout *mainLayout; QVector<QPushButton*> stopButton,restartButton; QVector<QProcess*> proc; QSignalMapper *stateSignalMapper, *stopSignalMapper, *restartSignalMapper; public slots: void openSettings(); void startRunning(); void statusChange(int); void stopProc(int); void restartProc(int); void renew(); }; class SWindow : public QWidget { Q_OBJECT public: SWindow(QWidget *parent=0); void readConfig(); void addLine(int); private: QVector<QPushButton*> selectButton; QVector<QLabel*> filePath; QVector<QLineEdit*> alias; QSignalMapper *selectSignalMapper; QVector<QSpinBox*> delay; QGridLayout *mainLayout; public slots: void selectFile(int); void saveFile(); void addLineSlot(); }; when i create and display SWindow object from mainWindow like this void mainWindow::openSettings() { config = new SWindow(); config->show(); } everything is ok, but now i need to access the mainWindow from SWindow, and void mainWindow::openSettings() { config = new SWindow(this); config->show(); } doesn't display SWindow. How can i display SWindow? How do i call a function on widget close?

  • Recommendation for tool/framework that follows the naked objects pattern?

    - by Marcus Munzert
    I am searching for a tool/framework that follows the naked objects pattern and is written in Java. I know about tools like for instance JMatter, Naked Objects and Domain Object Explorer. That's not exactly what I am searching for, though. Open source would be great, but doesn't need to be. My intention is to use that tool/framework for the purpose of model-driven software development to do the modeling part. Ideally, such a tool/framework would provide the option to use JPA to store/load objects.

  • Focus stealing is evil.

    - by lunixbochs
    A quick Google search for solutions to Focus Stealing in Windows reveals two main result categories: People suggesting incomplete solutions involving the ForegroundLockTimeout registry entry (or TweakUI, which I believe simply changes the aforementioned registry entry), which isn't very effective. Incessant hordes of Windows users complaining about it. It's particularly annoying in two common scenarios: Something triggers a program to popup a dialog window in the background while a fullscreen app is focused, causing the fullscreen app to minimize. A window steals focus while you are typing, stealing all of your keystrokes. If you happen to press Space, Enter, or trigger a keyboard shortcut (like Y for Yes), it can cause completely undesirable outcomes. What creative solutions can be applied to fix this problem for either or both of these scenarios?

  • Is an editable select box the right way?

    - by Neil Middleton
    I have a scenario where a user is emailing another user in an HTML based web app. For the To: field, the user may select one of a pre-defined list of emails OR enter their own ignoring the pre-defined options. What would be the best way of doing this from a UI point of view? I've looked at editable select boxes using jQuery but none seem to let you enter your own option. Is there some other UI mechanism that would work here?

  • Problems with UITableView when loading the view into the main window

    - by GuidoMB
    I've created a sub class of UITableViewController named LoginViewController with the XIB file using XCode. Then I opened the XIB file with IB and set the table's style to grouped. Finally I wrote the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]]; [window addSubview: loginViewController.view]; window.backgroundColor = [UIColor blueColor]; [window makeKeyAndVisible]; [window layoutSubviews]; } I set the window's background color to blue for you to see what the problem is. I put a link to the screenshot If I don't use the table style grouped the problem does not occur

  • Are there any modern GUI toolkits which implement a heirarchical menu buffer zone?

    - by scomar
    In Bruce Tognazzini's quiz on Fitt's Law, the question discussing the bottleneck in the hierarchical menu (as used in almost every modern desktop UI), talks about his design for the original Mac: The bottleneck is the passage between the first-level menu and the second-level menu. Users first slide the mouse pointer down to the category menu item. Then, they must carefully slide the mouse directly across (horizontally) in order to move the pointer into the secondary menu. The engineer who originally designed hierarchicals apparently had his forearm mounted on a track so that he could move it perfectly in a horizontal direction without any vertical component. Most of us, however, have our forarms mounted on a pivot we like to call our elbow. That means that moving our hand describes an arc, rather than a straight line. Demanding that pivoted people move a mouse pointer along in a straight line horizontally is just wrong. We are naturally going to slip downward even as we try to slide sideways. When we are not allowed to slip downward, the menu we're after is going to slam shut just before we get there. The Windows folks tried to overcome the pivot problem with a hack: If they see the user move down into range of the next item on the primary menu, they don't instantly close the second-level menu. Instead, they leave it open for around a half second, so, if users are really quick, they can be inaccurate but still get into the second-level menu before it slams shut. Unfortunately, people's reactions to heightened chance of error is to slow down, rather than speed up, a well-established phenomenon. Therefore, few users will ever figure out that moving faster could solve their problem. Microsoft's solution is exactly wrong. When I specified the Mac hierarchical menu algorthm in the mid-'80s, I called for a buffer zone shaped like a <, so that users could make an increasingly-greater error as they neared the hierarchical without fear of jumping to an unwanted menu. As long as the user's pointer was moving a few pixels over for every one down, on average, the menu stayed open, no matter how slow they moved. (Cancelling was still really easy; just deliberately move up or down.) This just blew me away! Such a simple idea which would result in a huge improvement in usability. I'm sure I'm not the only one who regularly has the next level of a menu slam shut because I don't move the mouse pointer in a perfectly horizontal line. So my question is: Are there any modern UI toolkits which implement this brilliant idea of a < shaped buffer zone in hierarchical menus? And if not, why not?!
