Confirming a design where I need to save where the user navigated to the screen.

A matter of design, which is a good implementation of the following?

I need to be able to save the location of the place where the user has scrolled, then when the user:

  1. Changing screens and returns to the previous screen.
  2. The application farm (moves the application at bottom) and opens the app again (move the app in the foreground).

The user scrolls automatically here where the user was before.

For example, if I have a VerticalFieldManager with the following text read only fields:

  • LabelField
  • LabelField
  • LabelField
  • LabelField
  • LabelField
  • ButtonField

The user scroll down to the third LabelField — two actions user above performs, returns to the screen, and scrolls down to the third TextField again.

Is the hardest part, I can't count on own dirty, muddy, or fields because it is read only the data and a ButtonField.

I can't use Manager.setFocus because the fields have an accent.

I think I can use Manager.setHorizontalScroll and Manager.getHorizontalScroll, but is there a better way?

Not sure that your arguments to change my suggestion.

"The user must be able to close the application."

If they close the applciation that they lose their position.  It happens in most of the applications.  Browsers do not open up on top of the page you were viewing when you close, for example.

"The user must be able to request the application thoroughly using the end key of red color"

You will not be able to stop this.  It will just happen.  Nothing for you to do.

"This is a pile of high display a screen where the Menu button is the main navigation.".

This does not preclude that I proposed either possible.  If you pop a screen and then later push it, my understanding (and experience) are that he's going to be redisplayed as it was when you jump it.  The screens are objects, they don't stop screens just because they aren't on the stack of the screen.

Also, I see no problem in what you descrtibed for a touchscreen device.

  • PC/tablet-is there a laboratory touchscreen top that works on windows 7 / 8, where the screen can detach the keyboard to use in the form of tablets, or screen can be reached for keyboard vertically or horizontally?

    Labtop / Tablet question -I'm shopping for a new Labtop.    Is there a laboratory touchscreen top that works on windows 7 / 8, where the screen can detach the keyboard used in the form of tablets and then transformed (with long vertical side) and attached to the keyboard to type a length full page (8.5 x 11 page) and then returned (long horizontal side) one attached to the keyboard (to be used as a stand) for a movie with all the features of present characteristics of a top laboratory such as 4 to 8 GB memory and a 500 GB hard drive (perhaps as part of the screen or connected to / through the keyboard, if it is used as a docking station)?

    It seems with all the technology of the tablet on the market that Microsoft or somebody would do something like that now.  Can someone help me? Thank you

    PS: My wife has an ASUS transformer where the screen detaches from the keyboard, so it can be used in the form of tablets.  When it is attached to the keyboard, the keyboard acts as a stand to sit on the counter for watching movies.  And then the keyboard and the screen can fold them together, so when it is closed there is a stand-alone case. This, however, runs the Android operating system.  Basically, I want this same design (for the potability in a Briefcase), but with it running Microsoft Windows so it can be used as any other labtop.  It the keyboard could have a number pad are associated with, that would be a bonus.

When I plug the clip into the computer, I remember what he put in some main screen. I need a market-thru to mp3 music. The last time I tried, got stuck on the radio lol.

  • My vision is deteriorating, and I need more contrast on the screen. Please notify.

    Clear blue lettering - instead of black - becomes difficult for me to read easily.   In addition, blut lettering on a white background is hard to read.

    Hello

    • Click Start
    • Click on Control Panel
    • Click Accessibility Options (maybe to do twice according to the display of the control panel)
    • Click the view tab
    • Check use high contrast
    • Adjust the cursor Options according to
    • Click OK

    The Magnifier and on-screen keyboard can also help (left at Control Panel - Accessibility Options).

    The mouse pointer options can also help, but this can depend on the mouse software installed. You can adjust the size of the pointer and leave trails of (temporary) pointer for example...

    • Click Start
    • Click on Control Panel
    • Click the mouse (if you are using the category view you will need to click on printers and other peripherals first)

    Explore and experiment with the options there to see if anyone of them help, you can always disable them again if you don't want them.

  • Bringing a typed paragraph, save on the screen?

    I typed a paragraph on a Web site, which topped out on me! Now, I've lost my paragraph that I tapped upward! Is anyway that I could always, somehow, bring up, my paragraph I typed, the site expired? There must be a way? Because when a site come up on my screen, the memory must save somehow? So, if it is still in memory, then it must be reduced to the top somehow, right? If this isn't the case, then so be. No biggy!

    Sorry, you can't get it back. It is gone for good.

  • Design requirement has evolved, savings where the user has navigated to.

    Continuing this thread: http://supportforums.blackberry.com/t5/Java-Development/Confirming-a-design-where-I-need-to-save-whe...

    Requirements have changed.

    I now need to save the position on the screen where the user has navigated to once the screen has been redesigned.

    Specific screens are relayed on and painted according to a TimerTask. Once the screen again, I must automatically reposition / scroll to the position that the user was on the screen.

    For example:

    1. A user can leave a screen open for ten seconds.
    2. A user scrolls down to 3/4 of the way down.
    3. Once this time is up, a TimerTask is executed and redraws the screen with new data.
    4. If the user did scroll down in a VerticalFieldManager 3/4 of the way down, once the screen is redrawn the user must be back to the same position - 3/4 of the way down in the VerticalFieldManager.

    Ideally, I would like to save the XYPoint and then reposition the screen for the XYPoint recorded - a small prototype needs to be done for my part, granted.

    However, is there a better design or any who has implemented this feature before on OS 5.0.0?

    Thank you.

    I did so with a Manager (s) personalized using the recursively offset of vertical scroll through the stack of Manager as suggested by Peter, but be aware that you must not only parchment of, but the position is within the screen/Manager to follow the actual position of the screen against the perceived one. Here is the code that I use in my manager with my custom functions:

    public final int getAbsoluteY(){
       int absY = (getY()+drawY);
       while( getManager() instanceof CustomLayoutManager ){
          return absY + ((CustomLayoutManager)getManager()).getAbsoluteY();
       }
       return absY;
    }

  • What are the files save to the server?

    Hello, I am currently evaluate the demo version of RoboHelp and have developed a sample project to WebHelp. My next step is to save the relevant files on one of our servers to see how it behaves, but I can't determine what files I need to save to the server. Can anyone help?

    Unless you have purchased the RoboEngine, there no reason to generate Webhelp Pro (exit on server dedicated to track usage, providing the natural language search, etc.). Webhelp is fine.

    The first user interface panel is where you set the start page and the default page to generate the output on your local machine. (I recommend that you change the default! SSL! path to a completely outside the HR Program Files directory.)

    The fourth user interface panel is where you set the directories of the server where you want to publish this same output. The beauty of the edition, is that HR will publish only the few files that have changed since the previous release, all the production each time (less network traffic).

    Good luck
