How do I move focus left/right/up/down

Imagine that you have created a customized with 5 place BitmapFields Manager placed like this:

..... [  ]

[ ]  [X]  [ ]

..... [  ]

where 'X' represents the selected field.

Now normally, if you move the trackball, the focus would go in linear order in which the fields have been added to the Manager.  So, they can move from the top to the left, middle, right, and then down.

But, given that if the trackball can move up, down, left, right, I want to be able to concentrate to the up/down/left/right of the fireplace which precede with a trackBall revealing movement?

In the handler, I know I can get the movement of the trackball with navigationMovement().  But I do not understand what to substitute in the My Manager or fields to achieve the desired result.

OK, understood the part I didn't understand the framework.  The API documentation tells you that you must "return true" to indicate that the movement has been handled with:

protected boolean navigationMovement (int dx, int dy, int, int time status) {}
int d;
Block b (block) = this.getFieldWithFocus ();
       
If (Math.abs (dx) > Math.abs (dy)) {}
If (dx > 0) {}
d = Board.RIGHT;
} else {}
d = Board.LEFT;
}
} else {}
If (dy > 0) {}
d = Board.DOWN;
} else {}
d = Board.UP;
}
}
       
newFocus(b,_d).setFocus ();        Focus new set
       
Returns true;        True, since we are consuming events and manages the update
}

So, basically, it's the only method I should use to control the change in emphasis.  This isn't at all obvious in the API, especially given the lack of mention on the return value.  Interestingly, some reminders require scythes and other true to indicate the "consumption" or the management of the event.

Anyway, problem solved.

  • Movements of left-right reversed with CS6 crops

    I had CS4 on an old PC, I recently bought a new PC and consider buying CS6. I got a demo of CS6 - when I crop an image and you want to adjust the location of my crop, the left and right movements are reversed compared to what they were on CS4 - how can I change this?

    In CS6, left & right keys move the default image. If you want to go back to the way it was in older versions of Photoshop (for around the choice of crops and not the image so that the crop tool), follow these steps:

    First, select the crop tool. On the menu bar above, click the dropdown settings.

    Select 'Use Classic Mode'. It will come back to legacy crop tool, you giving cultures control would have been pre - CS6.

    Look for the small square located in the lower right of the object when you are in the effects view.  Click on that little room and then you should see the arrow that allows you to specify the exact direction and the object will be moved by the effect of length.

  • How can I reactivate swipe left/right UX (Safari-like) in every night?

    Hit swiping itself works, but the animation is gone completely. Is there a way to reactivate it? I think that the feature has gone since mid-December. It makes FF so more friendly user, I hope that the disappearance is only temporary (and not caused by the costumes).

    Found the bug where to swipe animation is disabled by default, to turn it on go to about: config
    To enable it set browser.snapshots.limit to '5' (or any other value not zero).

  • How can I move my attachment or or down into a large list of attachments?

    I have a list of about 4 attachments.  But somehow they are mixed up.  How can I organize them so that they are in the order I want?

    I have Acrobat Pro XI.

    Hi thanks for getting back to me.

    Sorry I was not clear in my message.  I have about 40 attachments, and they are all jumbled up and messy.  I want to move them up and down and put them in the right order.

    I just thought of it.  I'm like the only way you can get them in the right order by renaming them alphabetically or numerically. that is to put an 01, 02, 03, in front of the file name.

  • Possible to save "live view on left, right, up, down"?

    According to the title. Is it possible to actually save it by default so every time I open a document the live view / code view is set up for my preference?

    Personally, I like my code on the left view and live on the right mode. It comes to messing around in the menus whenever I open a file. I'm 40 editing files at once? That's 80 times I need to go to the menu for just to change the way in which the document is presented for me to change. This happens with some frequency and is trying to turn me off wanting to use the product. Lately, I use notepad ++ for a lot of my editing simple because it is easier to change the code in this notebook replacement app (and just assume it'll look all good when I'm actually) it's to do something in Dreamweaver.

    Someone please please tell me this is something that can be fixed by messing around in the registry or file settings somewhere.

    Hello Hoek,

    When you make changes to the workspace and close Dreamweaver, to remember your preferences for window split.

    I suspect that your Dreamweaver got corrupted preferences and must be recreated. Please try the steps in the link below to restore preferences for Dreamweaver

    Restore preferences | Dreamweaver CS6, Dreamweaver CC

    Another solution would be to create a new workspace for you

    1. open the drop-down list at the top right of the Workspace > new workspace -click

    2. give it a name of your choice.

    3. make the changes to the workspace

    4. open the dropdown list workspace at the top right > click Save current


    5. close Dreamweaver and reopen to check if the same workspace it is kept or not.

    If this isn't the case, then restaurant preferences will fix the problem permanently.

  • How can I move the taskbar back to the bottom?

    Help please. How can I move the taskbar to back down on the side?

    Hello

    try to do this:

    To unlock the taskbar

       Right-click an empty space on the taskbar. If Lock the taskbar has a check mark next to it, the taskbar is locked. You can unlock it by clicking Lock the taskbar, which removes the check mark.

    To move the taskbar

       Click an empty space on the taskbar, and then hold down the mouse button as you drag the taskbar to one of the four edges of the desktop. When the taskbar is where you want it, release the mouse button.

    Note

           To lock the taskbar into place, right-click an empty space on the taskbar, and then click Lock the taskbar so that the check mark appears. Locking the taskbar helps prevent it being moved or resized accidentally.
