setHorizontalScroll
Hi all
I tried to find how to use the setHorizontalScroll() method, but it seems to not work in anyway I try.
When I call setHorizontalScroll(100,true); My HorizontalFieldManager is always the same
and when I call getHorizontalScroll(); It returns 0
I'm not sure "setHorizontalScroll (int position, boolean lively) is the method that automatically slides HFM to position when animate is set to true.
But if this is the case, I still don't know how to use it
It would be really nice if someone told me how to use it
I thank you very much.

According to my concern it willn't give you the effect of what you expect if you override the (de) touchEvent...
you override the touchEvent (). ?
touchEvent has nothing to do with it. New - you can check if setHorizontalScroll throws exceptions? It would be the most likely explanation why it does nothing.
Is your broad Manager (virtual width, that is) also - need to scroll? Have HORIZONTAL_SCROLL style bit set?

BlackBerry OS 6.0: ScrollView.setHorizontalScroll () does not work
In OS 6.0, we now have a ScrollView http://www.blackberry.com/developers/docs/6.0.0api/net/rim/device/api/ui/ScrollView.html
However, I was faced with the following problem:
manager.setHorizontalScroll (15);
int x = manager.getHorizontalScroll)
at the end x = 0;
Does anyone else have this disorder?
The problem is resolved. I do not call setVirtualExtent() during sublayout(). In 5.0 and below which works very well, but in 6.0 it is buggy.

How to set horizontal scrolling to horizontal field Manager when fields are added using a loop for?
The following code snippet contains a horizontal field Manager to which are added five buttons.
1. I can't the value of horizontal scrolling to horizontal management Manager because of who I am not able to access the keys 4 and 5.
2. usually, we put horizontal scrolling in the following way:
container = new HorizontalFieldManager(USE_ALL_WIDTH|HORIZONTAL_SCROLL|HORIZONTAL_SCROLLBAR);
3. so I also tried setting of horizontal scrolling in the following way
container = new HorizontalFieldManager(Manager.HORIZONTAL_SCROLL|Manager.HORIZONTAL_SCROLLBAR) { protected void sublayout(int maxWidth, int maxHeight) { Field field = null; int x = 0; int y = 0; int maxFieldHeight = 0; int maxFieldWidth = 0; for (int i = 0; i < getFieldCount(); i++) { field = getField(i); layoutChild(field, maxWidth, maxHeight); setPositionChild(field, x/*width-field.getWidth()*/,y); x+=field.getWidth(); maxFieldWidth = maxFieldWidth + field.getWidth(); System.out.println("field width"+field.getWidth()); System.out.println(" max field width"+maxFieldWidth); if(i==0) { maxFieldHeight = field.getHeight(); // height set of the first button since all components have the same height } } System.out.println("final max field width"+maxFieldWidth); setExtent(maxFieldWidth, maxFieldHeight); } };but it's not working.

Please help me.
I think that there is a bug in the sublayout (your HorizontalFieldManager 0 mode. Given that the code did what I think WHAT HFM will do anyway, I recommend that you try to do this with a standard HFM, using this style:
Manager.HORIZONTAL_SCROLL | Manager.HORIZONTAL_SCROLLBAR
Let us know how you go.
When I have more time I'll explain the bug, but if you want to investigate something, be aware that the maximum size that you can use in setExtent are the values that are passed to sublayout. Compare the width as you try to define in setExtent whose width is increased.

dominant touch event handler replaces all other fields
I have the code following, which uses gestures to perform scrolling on my hfm, but substitution of this hfm, replace essentially all fields on the screen, making them useless. How is this possible, I thought that this specific touchEvent belonged to the hfm? How to work around this problem and just disable scroll for the hfm?
gallery = new CustomHFM(){ protected void sublayout(int maxWidth, int maxHeight){ super.sublayout(maxWidth, 200); setExtent(maxWidth,200); } protected boolean touchEvent(TouchEvent message){ int eventCode = message.getEvent(); if(eventCode == TouchEvent.GESTURE){ System.out.println("SWIPE GESTURE"); TouchGesture g = message.getGesture(); int gesturecode = g.getEvent(); int direction = g.getSwipeDirection(); //gallery.setHorizontalScroll(page_two, true); if(direction == TouchGesture.SWIPE_WEST) slideNext(); if(direction == TouchGesture.SWIPE_EAST) slidePrev(); pressed = true; } if(eventCode == TouchEvent.UP){ pressed = false; //slide(); } return true; } };I want to just do not use the default scroll and do my own thing! Any suggestion would be appreciated, I'm really in the fire right now.
OK, this is a different problem. I suspect that you must reject touch events that are not actually within your HFM. Then add code like the following at the beginning of your touchEvent method:
int x = message.getX (1);
int y = message.getY (1);
If (x < 0="" ||="" y=""> < 0="" ||="" x=""> getExtent () .width: y > getExtent () .height) {}
Outside the scope
Returns false;
}If this is not enough, so be sure that your touchEvent method is called. If it really is, then I think you have a problem with a Manager. You have all Directors complicated on your screen. Try to simplify the screen so that you don't use native components RIM (and nothing implying positioning as AbsoluteFieldmanager and see if the problem persists.) If so, then see if you can post an example of the sample that shows the problem so that we can all try.

Swipping effect as app world application
Hello..
I want to show my screen effect swipping left-right as the home screen in torch with app world. Any API for this?
Anyone got the idea?
Thank you.
The only way I know to achieve this is to have two different screens in a HorizontalFieldManager, make sure that both are limited by the width to 1 width of the device, then use horizontal scrolling (setHorizontalScroll()) to move the scroll position in the HorizontalFieldManager in some kind of loop timer.
I'm sure there are other ways, but that's what I would try first.

effect of animation for horizontal field Manager
Hello
I have three willing fieldManagers horizontally in the content ofaverage fieldmanager will change on click of a button
is it possible to apply slide in French - sliding effect to these content?
I don't want to do the new screen n again?
Wrap the Middle Manager in a HorizontalFieldManager (HORIZONTAL_SCROLL). When you want to remove the old content and slide into the new, follow these steps:
(1) adds the new content the HFM;
(2) an animation slide to the left edge of the old content (probably 0) up to the left edge of the new (getLeft() returns). Use the method suggested by Peter;
(3) once the animation finished, remove old content and setHorizontalScroll on the HFM wrapping to 0 (since the new content now starts it).

I want to develop the UI for a screen which I join... on ehelp me please to write code for the user interface
akhilmuppa wrote:
Main box is a text box, and it will scroll vertically and horizontally...
Yes, really, I have problem with header, I've tried in many ways with many managers, but it does not display the two textfielld and button .so please help me solve this problem... As I referred to it a few docs but I force get the solution
OK, then you create your screen with both VERTICAL_SCROLL and HORIZONTAL_SCROLL flags. The main area Manager (which is not directly visible to you if you can get the reference through getMainManager) is a VerticalFieldManager, so it will hold the fields vertically (duh!). However, thanks to the HORIZONTAL_SCROLL indicator, it will allow wider than the screen fields to get what they want and will be able to scroll horizontally - either programmatically (setHorizontalScroll) or 'naturally' when the focus moves outside the visible area.
As for the problem with the textfield and button, there are two ways to solve it.
For example, if you searched "width-hungry" as I suggested, you would have found, for example, this thread:
EditField and checkboxfield on the same line
Take a look at the solution - it's one of the ways to do so: simply create a field that will be limited to how much of the piece.
The second solution would be to create a Manager customized for this particular configuration of TextField left and ButtonField right. The Manager will always have exactly two fields, in this exact order, so you can write his sublayout invoking it.
So, what does ' protected void sublayout (int maxWidth, maxHeight) ? It does the following things:
(1) receives the maximum width and height it can occupy in the parent Manager (see maxWidth and maxHeight parameters);
(2) tells the Manager (managed fields) how room child within this handler they can get (using layoutChild (child of field, int height, int width)). After that (and only after that) he knows how this child will be actually using child.getExtent (any form) or (if you want width and height separately) child.getWidth()/child.getHeight (). It is normal that any Manager to expose a child, get its dimensions, adjust the width and height according to the remaining information then continue carrying the children in the same way.
(3) positions of its children using the setPositionChild (child field, int x, int y) call. Positions are relative to its upper-left corner (which is (0,0)).
(4) calculates the height and width that result and sets using setExtent (int width, int height).
Try to write the handler using these data as well as the link provided Simon and come back here if you still have problems. By the way, take a look at sublayout to JustifiedEvenlySpacedHorizontalFieldManager for a good example.

A pointer that moves when the user navigates screen
I have a screen that contains different fields/images. Some of them are focusable and others are not. Is it possible to print/display an arrow pointer that moves as the user moves the wheel? And the arrow pointer can be on the oilfields focusable and non-focus when the user stops and wheel. It's like the pointer inside of a browser (office or by phone).
Is there a simple way to do this, or it will be complicated in a way...
Thank you
Man
Complicated enough without doubt.
You can override moveFocus() to set the position of the cursor. You need to avoid moving focusable developed by calling fields do not super.moveFocus (). If you want to set focus when you click, you could get the cursor position and then go the extra fields and call XYRect.contains(x,y) with their Field.getExtent ().
When scrolling you have to make sure the cusror is visible by calling setVerticalScroll(), setHorizontalScroll(), or maybe just Screen.scroll ().

Hello, I have a problem.
My friend and I have created a table.
It looks like this:
However, we want different sections to scroll independently. For example, you can already guess, we want the time to scroll vertically when cells move vertically but not when they move horizontally. And we want the days to scroll horizontally with the cells, but not vertically. In my head that managers overlap or something. Any suggestions please?
Don't you worry your companion in mind. I managed to do the work. I just changed the listener of scrolling. and the managers to which I applied to them. I added only the earpiece scrolling to the administrator who had the main editable cells and the code looks like this
....
public void scrollChanged(Manager, int verticalChange, int horizontalChange) { (The manager I wanted to scroll vertically).setVerticalScroll(verticalChange); (The manager I wanted to scroll horizontally).setHorizontalScroll(horizontalChange); }//Voila it works!
Thank you for everything. You really helped to guide me on the right track -
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:
- Changing screens and returns to the previous screen.
- 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.

Use the scrolling Vertical and Horizontal
Hi all, I am new to BB. I tried to do a manager can scroll through both vertical and horizontal. I want to do a Picture Manager only a BitmapField, where the BitmapField have width and height more than display, and the Manager could scroll through both vertical and horizontal, so I can't look at BitmapField.
I read and try to do something like this ( http://supportforums.blackberry.com/t5/Java-Development/How-to-make-Vertical-and-Horizontal-scroll-o... ) and this one ( http://208.74.204.192/t5/Java-Development/How-can-i-use-both-of-horizontal-scroll-and-vertical-scrol... ) but it does not work
in general I want to do something like ZoomScreen (I do not use zoomscreen, because I can not add the button or another field in this thing).
I have try this one too, but nothing...
BEGIN
public myScreen() {}
_Image = new VerticalFieldManager VerticalFieldManager (Manager.VERTICAL_SCROLL |) Manager.HORIZONTAL_SCROLL) {}
protected void moveFocus (int x, int y, int status time int) {}
setVerticalScroll (y);
setHorizontalScroll (x);
super.moveFocus (x, y, status, time);
};
};B=Bitmap.getBitmapResource("img/edit.jpg bitmap image");
BitmapField bi = new BitmapField (b, BitmapField.USE_ALL_WIDTH);_image. Add (BI);
Add (_image);}
END
Thanks for the reply... and sorry for my bad English (Not My Mom Language;-D)
Welcome to the forums!
USE_ALL_WIDTH first, remove your BitmapField constructor - as is, it will become monstrously huge (a width of Integer.MAX_VALUE > 1). A default constructor is sufficient. You may need to add FOCUSABLE style according to your needs.
Second, your moveFocus method is quite useless, because it is called only on touchscreen devices when the user touches that particular place. Touchscreen can already reach moving-scroll and swipe scrolling, so your problem is automatically solved it. In addition, moveFocus is a call relatively high level - all of these calls work well on a screen with many focusable fields and other things.
You will need to substitute navigationMovement for the BitmapField if it is FOCUSABLE or the screen itself. If you want other fields on the screen, this task becomes really not negligible, so formalize the specs for this screen as much as you can before you implement it. When you have an exact plan, write here, if you still need help.

Hello
Please how can I do a scroll smoothly. I have a HorizontalFieldManager I try adding some VerticalFieldManager using full width appear, I want to display the next VerticalFieldManager when scrolling user as the Launcher of the iphone.
I tried this ground but this doesn't work:
hfm.setScrollListener (new ScrollChangeListener() {}
' Public Sub scrollChanged (Manager, int newHorizontalScroll,
{int newVerticalScroll)
int fieldIndex = hfm.getFieldAtLocation (newHorizontalScroll + getScreen () .getWidth (), 0);
hfm.getField (fieldIndex) .setFocus ();
System.out.println("***fieldIndex"+fieldIndex);
Invalidate();
HFM. Invalidate();}
also I tried, but I'm going into an infinite loop
hfm.setScrollListener (new ScrollChangeListener() {}
If (!.) MY_CHANGING_SCROLL) {}
MY_CHANGING_SCROLL = true;
If (Math.abs (lasthorizontalScroll - newHorizontalScroll) > (getScreen () .getWidth () / 5))

Problem Manager of horizontal scrolling for OS 6.0 and more?
Hi all. I have a problem with the Manager of Horizontal scrolling. Every thing worked for OS 5.0 and below, the question arises for OS 6.0 and more. For example, check the following:
I have 2 HFM added to the optimization of resources.
HFM1 - contains 2 buttons.
HFM2 - contains 6 buttons, and the user can scroll between the buttons.
The questions is when user keep hitting the right key, when the focus is on the second button of HFM1, then the content of HFM2 scrolls to the right - what is bad behavior.
Check the screenshot for Simulator 9810 (when scrolling to the right inside the HFM which contains the test1, test2 scrolls the second HFM):
Scrolling in a managing scrools in another, why this happen and how that might be solved?
Thank you in advance.
Finally, I found a solution using ScrollChangeListener (SCL).
So what I did I set the SCL for HFM2, then:
public void scrollChanged(final Manager manager, int newHorizontalScroll, int newVerticalScroll) { //----> fixing the issue when one HFM scroll another one for OS 6.0 and above int fwf = manager.getFieldWithFocusIndex(); if (fwf == -1) manager.setHorizontalScroll(0); //<---- fixing the issue when one HFM scroll another one for OS 6.0 and above }Thanks to all in any case.
