GridFieldManager
Hello friends
Well, my doubt is that I try to manage a grid of the domain manager and add a field, that the problem is that my gridfieldmanager I create
mesaManager = new GridFieldManager (2, 5, Field.FIELD_HCENTER) {}
protected void sublayout (int width, int height) {}
Width = 300;
height = 140;
setExtent (width, height);
Super.sublayout (width, height);
}
};
and when I try to mesaManager.add I can not give a hint of error bound, how I can add items (fields) to my gridfieldmanager?
Sorry my bad English
Please, I'm waiting for your help
It make much sense to use a special layout manager and crush its layout.
Visit this link on the custom layout managers:
If you want to use a GridFieldManager use it without replacing the page layout.

Thank you
Like this you can do:

Thanks for the reply.
Yes, I know GridFieldManager.AUTO_SIZE work very well. But I can't zoom in GridFieldManager.FIXED_SIZE problem.

How to align the areas that fall within GridFieldManager
Hello
I have a GridFieldManager and I want to align the first three fields on the left and the last to the right. I tried to use ad FIELD_LEFT FIELD_RIGHT, but this does not seem to do the trick. Any ideas?
My code:
GridFieldManager grid = new GridFieldManager(3, 4, USE_ALL_WIDTH | NON_FOCUSABLE); for (int i = 0; i < data.length; i++) { LabelField label = new LabelField(data[i].getS1(), FIELD_LEFT | NON_FOCUSABLE); LabelField value = new LabelField(data[i].getS2(), FIELD_LEFT | NON_FOCUSABLE); LabelField unit = new LabelField(data[i].getS3(), FIELD_LEFT | NON_FOCUSABLE); BitmapField pic = new BitmapField(b, FIELD_RIGHT | NON_FOCUSABLE); grid.insert(label, i, 0); grid.insert(value, i, 1); grid.insert(unit, i, 2); grid.insert(pic, i, 3); } add(grid);Hello
Try using Insert with a style:
grid.insert(label, i, 0, FIELD_LEFT);

rotation on GridFieldManager problem
Hello world
I'm having a hard time trying to manage the rotation for GridFieldManager.
I put the properties of column as GridFieldManager.FIXED_SIZE. I add the data to the grid. Then I add the grid to an absolute layout manager. And in the case of rotation, change the properties of the column in the sublayout of the absolute layout manager. Nothing changes.
Could you please suggest a better approach to this problem?
Kind regards
I do not see GridFieldManager code in there, I assume that it is this code that is changing things.
There is a round floating GridFieldManager that initially seemed to come from the code provided by Anthony Rizk in his book "Beginning BlackBerry Development". I looked at this code, but to do this kind of layout, I prefer TableLayoutManager, which is a bit of code provided to the RIM. You will find it here:

Focus with GridFieldManager problem
I'm having a problem of development/unfocus. A label should draw a border of red around him when it gets the focus and a black border when he loses it. But when I add/remove a label for a GridFieldManager (see below the code and the screenshot), I find that the update will temporarily to the field at (0,0) and 'loses' never the focus - in other words, he draws a red border, but never black. So, I end up having 2 fields with the red border - something that should never happen!
I'm under 5.0 SDK on Eclipse. I reproduced the problem in the simplest possible form: If you import the following code, you'll see for yourself. Please help me!
Import net.rim.device.api.ui.XYEdges;
Import net.rim.device.api.ui.component.LabelField;
Import net.rim.device.api.ui.container.GridFieldManager;
Import net.rim.device.api.ui.container.MainScreen;
Import net.rim.device.api.ui.decor.Border;
Import net.rim.device.api.ui.decor.BorderFactory;/ public final class screen extends MyScreen
{
private GridFieldManager MDT;
public MyScreen()
{
Set the displayed title of the screen
setTitle ("MyTitle");
int size = 3;
GFM = new GridFieldManager (size, size, GridFieldManager.FIELD_HCENTER |) GridFieldManager.FOCUSABLE);
for (int y = 0; y)< size;="" y++)="">
for (int x = 0; x)< size;="" x++)="">
LabelField nf = new LabelField ("H", LabelField.FOCUSABLE) {}
protected boolean navigationClick (int time, int status) {}
swap (this);
this.setFocus ();
Returns true;
}Protected Sub onFocus (int direction) {}
this.setBorder (BorderFactory.createSimpleBorder (new XYEdges (1,1,1,1), new XYEdges(0xFF0000,0xFF0000,0xFF0000,0xFF0000), Border.STYLE_DASHED));
}
protected void onUnfocus () {}
this.setBorder (BorderFactory.createSimpleBorder (XYEdges (1,1,1,1))) of new;
}};
nf.setBorder (BorderFactory.createSimpleBorder (XYEdges (1,1,1,1))) of new;
GFM. Add (NF);
}
}
Add (GFM);
}
private void swap (LabelField lf) {}
GFM. Delete (LF);
GFM. Add (LF);
}
}Thus, even if I clicked on the intermediate element, an area of development is established around the item to (0,0)
Why is this?
Sorry to get to this post, this late - I could have saved a lot of traffic if I noticed it earlier...
In any case - onUnfocus has a very strange behavior. In some cases (I don't know which) it is not called at all when the field loses focus. So, rather than using onFocus/onUnfocus pair, use FocusChangeListener. This listener will turn on the eventType and onFocus on FOCUS_GAINED work and the work of onUnfocus on FOCUS_LOST.
Overall, it will look like this:
import net.rim.device.api.ui.XYEdges; import net.rim.device.api.ui.component.LabelField; import net.rim.device.api.ui.container.GridFieldManager; import net.rim.device.api.ui.container.MainScreen; import net.rim.device.api.ui.decor.Border; import net.rim.device.api.ui.decor.BorderFactory; public final class MyScreen extends MainScreen { private GridFieldManager gfm; public MyScreen() { // Set the displayed title of the screen setTitle("MyTitle"); int size = 3; FocusChangeListener fcl = new FocusChangeListener() { public void focusChanged(Field field, int eventType) { switch (eventType) { case FOCUS_GAINED: field.setBorder(BorderFactory.createSimpleBorder(new XYEdges(1,1,1,1), new XYEdges(0xFF0000,0xFF0000,0xFF0000,0xFF0000), Border.STYLE_DASHED), false); break; case FOCUS_LOST: field.setBorder(BorderFactory.createSimpleBorder(new XYEdges(1,1,1,1)), false); break; case FOCUS_CHANGED: break; default: break; } } }; gfm = new GridFieldManager(size,size,GridFieldManager.FIELD_HCENTER|GridFieldManager.FOCUSABLE); for (int y = 0; y < size; y++) { for (int x = 0; x < size; x++) { LabelField nf = new LabelField("H", LabelField.FOCUSABLE) { protected boolean navigationClick(int time, int status) { swap(this) ; this.setFocus(); return true; } }; nf.setBorder(BorderFactory.createSimpleBorder(new XYEdges(1,1,1,1))); nf.setFocusListener(fcl); gfm.add(nf); } } add(gfm); } private void swap(LabelField lf){ gfm.delete(lf); gfm.add(lf); } }You will notice that I have created a FocusChangeListener to listen each LabelField and changed calls setBorder on focus has changed not update in page layout (as does not change the size of the border), which will make it much more effective and does not cause the entire screen redraw
You can do even better if you setBorder on the ground as it is created, but use the long form - viewable one following first parameter. Define borders forVISUAL_STATE_FOCU andVISUAL_STATE_NORMA at least. Again, take a long look at prototypes withupdateLayou indicator. This way you won't have to worry about changes in development at all - the system will do it for you

GridFieldManager with label get wider
I searched the forums, but can't find the answer to my problem. so, who can help me here.
I have a GridFieldManager, with 2 containing static text and two labels with the text I want to change during execution.
GridFieldManager gfm = new GridFieldManager(2, 2, Manager.USE_ALL_WIDTH | GridFieldManager.FIXED_SIZE); gfm.setColumnProperty(0, GridFieldManager.FIXED_SIZE, 300); gfm.setColumnProperty(1, GridFieldManager.FIXED_SIZE, 180); float TMeasured = 180 / 10; float TSetpoint = 195 / 10; lTemperatureMeasured = new LabelField(Float.toString(TMeasured) + "°c"); lTemperatureSetpoint = new LabelField(Float.toString(TSetpoint) + "°c"); gfm.add(new LabelField("Temperature measured"), FIELD_LEFT); gfm.add(lTemperatureMeasured, FIELD_LEFT);//RIGHT); gfm.add(new LabelField("Temperature setting"), FIELD_LEFT); gfm.add(lTemperatureSetpoint, FIELD_LEFT);//RIGHT); add(gfm);the problem is that when I change the text of the label, the GridFieldManager becomes wider! simply, it grows and grows by something like 5 pixels. change the fixed width did not help.
I just can't understand why this happens. who does that?
Text editing is done with a button:
public void fieldChanged(Field field, int context) { if(field == bChangeTemperature) { lTemperatureSetpoint.setText("t"); } }

Focus BitmapField occuping all GridFieldManager cell...
Hello
I have the following problem, I have a Focus bitmapfield 30 x 30 which I add to a 100 x 100 GridFieldManager cell.
The problem is when I click in the cell, but out of the picture, the complete cell concentrates and the navigationClick is still running... How can adjust the focus to the image and not the cell area?
My code is very simple
BitmapField refreshImg = new BitmapField(Bitmap.getBitmapResource(RutasUtils.REFRESH_IMAGE),BitmapField.FOCUSABLE); grid.add(refreshImg);
OK, thanks anyway.
I found a 'solution '.
I use setPadding, because I am by aligning the button refresh to the upper right. Instead of using zero for the bottom and left padding, I increased the value to convert the entire region of the 'empty' cell padding and to avoid the previous behavior:
refreshImg.setPadding (5, 10, 55, 10);

FieldChangeListener for a GridFieldManager element
Hello
I have a GridFieldManager loaded with lots of elements in the horizontalFieldManagers type. I noticed after you add managers to GridFieldManager and appellant getFieldAtIndex to my GridFieldManager, she will return me a FIELD. Can I put a FieldChangeListener to the returned field? What I know is that I couldn't do it at HorizontalFieldManager. But I can do this returned field?
My intention is to create a list, whenever you click on one of the elements, it will change the content of the gridfieldmanager.
Thank you very much!
Yes, but BitmapFields does not normally change so don't do not normally call the change listener. You need to implement yourself for the field. It's easy, substitute navigationClick and touchEvent. There are many examples on this forum looking for an Image button.

Dear all,
I tried to implement a GridFieldManager by copying one of the displayed example. I realize that there is a such GridFieldManager documented in API 5.0. However, I may need to cater for older devices, i.e. running 4.5. The problem is after I added in BitmapFields in this GridFieldManager and I try to navigate around, the first field is always focused. He never sail anywhere. Here are the updated navigationMovement
protected boolean navigationMovement (int dx, int dy, int, int time status) {}
int focusIndex = getFieldWithFocusIndex();
While (dy > 0) {}
focusIndex += columns;
{If (focusIndex > = {getFieldCount())}
Returns false; The focus moves on this manager
}
else {}
Field f = getField (focusIndex);
If (f.isFocusable ()) {/ / only move the focus on the fields of the object of focus}
If (f instanceof ImageButtonField)
{
IBF ImageButtonField = f (ImageButtonField);
If (IBF.isOnFocus ())
{
f.setFocus ();
-DY;
}
}
on the other
{
f.setFocus ();
-DY;
}
}
}
}
While (dy< 0)="">
focusIndex = columns;
If (focusIndex< 0)="">
Returns false;
}
else {}
Field f = getField (focusIndex);
If (f.isFocusable ()) {}
If (f instanceof ImageButtonField)
{
IBF ImageButtonField = f (ImageButtonField);
If (IBF.isOnFocus ())
{
f.setFocus ();
DY ++;
}
}
on the other
{
f.setFocus ();
DY ++;
}
}
}
}
While (dx > 0) {}
focusIndex ++;
{If (focusIndex > = {getFieldCount())}
Returns false;
}
else {}
Field f = getField (focusIndex);
If (f.isFocusable ()) {}
If (f instanceof ImageButtonField)
{
IBF ImageButtonField = f (ImageButtonField);
If (IBF.isOnFocus ())
{
f.setFocus ();
-DX;
}
}
on the other
{
f.setFocus ();
-DX;
}
}
}
}
While (dx< 0)="">
-focusIndex;
If (focusIndex< 0)="">
Returns false;
}
else {}
Field f = getField (focusIndex);
If (f.isFocusable ())
{
If (f instanceof ImageButtonField)
{
IBF ImageButtonField = f (ImageButtonField);
If (IBF.isOnFocus ())
{
f.setFocus ();
DX ++;
}
}
on the other
{
f.setFocus ();
DX ++;
}
}
}
}
Returns true;
}I wonder if there is a problem with it. Help, please. Thank you...
Hi guys,.
apparently moveFocus (focusIndex, status, time); the round is played. I have inserted after f.setFocus.

Strange: Objectchoicefield and ObjectListField in Gridfieldmanager - navigation problem
Hi @all,
I have a very strange problem, because running Simulator runs as I would have liked, but the device, the navigation is bad:
running OS 5.0.0.42 3 on device (BB9700) and the Simulator
1. the building screen
2. put verticalfieldmanager on it that contains the background image
3. put gridscreenmanager (with a column - the problem is with more then one column, too) on the first position of the vfm
4. turn objectchoicefield with 5 points on the 1st row of the gsm
5. put the objectlistfield with 5 points on the second line of gsm
Program running in the Simulator:
View all as I prefer.
The first objectchoicefield and beyond the objectlistfield.
When I scroll with trackpad OCF Gets the focus first and after that the olf on its first line.
I can scroll up and down, and everything's fine.
Program running on the device:
View all as I prefer.
The first objectchoicefield and beyond the objectlistfield.
When I scroll with trackpad OCF Gets the focus first and after that the olf on its first line.
So far so good:
When I scroll down to the olf, all things are working properly. For example, point 4 a now focus.
Now, if I try to go back in the OLF, it should go back to article 3 of the olf, but this is the leap into objectchoicefield. After that, if I try to go back to the objectlistfield, it jumps directly to point 4, which he came before.
If I don't put the objectchoicefield in the first row, everything works fine.
What can I do?
I did something wrong?
All ideas are very appeciated.
Thanks in advance.

Well, I found it.
I made a mistake in the application of my own gridfieldmanager navigationmovement method.
What is already strange: I used the same gridfieldmanager within 2 screens in my application. First screen was working fine, the second one was bad. Same content in both screens.
Sorry for that.
Thank you for all.

Move the icons in GridFieldManager
Hello
Trying to develop an application that contains the icons arranged in a grid using GridFieldManager.
Currently positions of the icons are fixed once they are added to the grid.
Is there a way to do such as users are able to rearrange the position of the icons in the grid? for example, move to a different empty location in the grid.
A good example would be like the menu BB where we can highlight the icon, select 'Move' and choose the new location.
Appreciate any help I can get.
Thank you very much in advance!
You can call the invalidate on your screen method to force the latter to be redrawn. You should not pop and push a screen just for him having to redraw themselves.

Difficulties to align LabelFields inside a GridFieldManager
Hi all!
As stated in the subject, I can't align inside a gridfieldmanager labelfields.
I'm confused because I am able to align with BitmapFields using attributes of DraweStyle (TOP, BOTTOM, or LEFT), but that does nothing on LabelFields.
Again, am I not suppose to use field rather than the DrawStyle attributes attributes? because even on BitmapFields, it does not.
Here is a simple code with just LabelFields:
grid = new GridFieldManager(4, 3, Manager.USE_ALL_HEIGHT | Manager.USE_ALL_WIDTH); grid.setColumnProperty(0, GridFieldManager.AUTO_SIZE, 0);grid.setColumnProperty(1, GridFieldManager.AUTO_SIZE, 0);grid.setColumnProperty(2, GridFieldManager.AUTO_SIZE, 0); grid.setRowProperty(0, GridFieldManager.AUTO_SIZE, 0);grid.setRowProperty(1, GridFieldManager.AUTO_SIZE, 0);grid.setRowProperty(2, GridFieldManager.AUTO_SIZE, 0);grid.setRowProperty(3, GridFieldManager.AUTO_SIZE, 0); mainVerticalFieldManager.add(grid);grid.add(new LabelField("----", Field.FIELD_BOTTOM));grid.add(new LabelField("----", Field.FIELD_TOP));grid.add(new LabelField("----", Field.FIELD_LEFT));grid.add(new LabelField("----", Field.FIELD_RIGHT));grid.add(new LabelField("----"));grid.add(new LabelField("----"));grid.add(new LabelField("----"));grid.add(new LabelField("----"));grid.add(new LabelField("----"));grid.add(new LabelField("----"));grid.add(new LabelField("----"));grid.add(new LabelField("----"));The LabelFields are perfectly horizontally and vertically centered yet they shouldn't.
I hope someone can help.
Thank you.
