I am using EditField in my application. The EditField is editable while using virtual keyboard but it requires long press to edit with quetry keypad. I tried all possible way which I can but didn't find what is causing the problem.
I am testing it in Torch 9800. Is there any clue about it please welcome.
//FOR NICKNAME SEARCH

This is may be old question but i dont get proper solution
if it is wrong please ignore otherwise please halp me
I have one main screen with two verticleManagers
1)For browserField
2)one button
first i add successfully My Browserfield to First verticlemanger and also add button to second verticlemanager
finally two verticlemanager added to main screen.
in OS6 i dont get any problem it works fine
but in OS5 i got problem that is
once the Browserfield is getting focus, it never release its focus so i am unable to navigate downside of the Browserfield. Means i am unable to click on blackberry advertisement Banner.i am unable to navigate down from browserfield using trackpad
this is my sample code
class browserScreen extends MainScreen
{
String url;
BrowserField browserField;
public browserScreen() {
VerticalFieldManager main_mgr=new VerticalFieldManager(){
protected void sublayout(int maxWidth, int maxHeight) {
super.sublayout(Display.getWidth(),Display.getHeight());
setExtent(Display.getWidth(),Display.getHeight());
}
};
VerticalFieldManager browserfield_mgr=new VerticalFieldManager(){
protected void sublayout(int maxWidth, int maxHeight) {
super.sublayout(Display.getWidth(),Display.getHeight()-50);
setExtent(Display.getWidth(),Display.getHeight()-50);
}
};

browserFieldConfig.setProperty(BrowserFieldConfig.JAVASCRIPT_ENABLED,Boolean.TRUE);
browserFieldConfig.setProperty(BrowserFieldConfig.ALLOW_CS_XHR,Boolean.TRUE);
browserField=new BrowserField(browserFieldConfig);
browserField.requestContent(url);
browserfield_mgr.add(browserField);
main_mgr.add(browserfield_mgr);
VerticalFieldManager button_mgr=new VerticalFieldManager(){
protected void sublayout(int maxWidth, int maxHeight) {
super.sublayout(Display.getWidth(),50);
setExtent(Display.getWidth(),50);
}
};
button_mgr.add(new SeparatorField());
ButtonField btn=new ButtonField("BUTTON MANAGER");
button_mgr.add(btn);
main_mgr.add(button_mgr);
add(main_mgr);
}
}
any help can be appreciated
After i googled a lot i conclude that This is OS 5 issue. it wont resolve it in OS5. It resolved In OS6. You have to provide a way to move the focus off the BrowserField yourself. I have tried a variety of mechanisms to do this, like detecting Escape in the Screen's keyChar method, the best I have found so far is to use the Menu and give the users the option of swapping focus out of the BrowserField. In general I do not recommend sharing the Screen between a Web Field and any other.

This is a bug in OS5. Its been fixed in os6 and upwards . These are the reasons why you are seeing the strange behaviour. You cannot get the same behaviour in os5. The only thing you could do is a hack, which is to setfocus on the button_mgr . The code will look like this.
// override the invokeAction method
public boolean invokeAction(int action) {
Field f = getFieldWithFocus();
// check the type of field you are looking for ,
//here i am checking if its a verticalfieldmanager
if (f instanceof VerticalFieldManager) {
button_mgr.setFocus();
return true;
}
return super.invokeAction(action);
}
this will setfocus on your button.
In my application there is one MainScreen .This screen contain lots of Vertical and Horizontal field manager and all content display successfully with scroll .
This is my main VerticalFieldmanager code .
vfm_Main = new VerticalFieldManager()
{
public void paint(Graphics g)
{
g.setColor(Color.WHITE);
g.drawBitmap(0,0,mybackgroundImage.getWidth(),mybackgroundImage.getHeight(),mybackgroundImage,0,0);
super.paint(g);
}
protected void sublayout(int maxWidth, int maxHeight)
{
super.sublayout(Display.getWidth(),Display.getHeight());
setExtent(Display.getWidth(),Display.getHeight());
}
};
there is one background image draw for this screen . When i scroll this screen to see the full content of this screen my Background image also scroll with the content ..for that reason background image looks so blury and it is repeat at the bottom of the screen .
i want to scroll only the content of that screen .so how to implement this ..?
i had try alot but not getting any suggetion and hits to prevent that ?
if any one facing this problem or have any idea please help me ...
Thanks in Advance !!!
You have to do like this:
vfm_Main = new VerticalFieldManager()
{
public void paint(Graphics g)
{
g.setColor(Color.WHITE);
g.drawBitmap(0,0,mybackgroundImage.getWidth(),mybackgroundImage.getHeight(),mybackgroundImage,0,0);
super.paint(g);
}
protected void sublayout(int maxWidth, int maxHeight)
{
super.sublayout(Display.getWidth(),Display.getHeight());
setExtent(Display.getWidth(),Display.getHeight());
}
};
subver=new VerticalFieldManager(VERTICAL_SCROLL|VERTICAL_SCROLLBAR)
{
protected void sublayout(int maxWidth, int maxHeight)
{
super.sublayout(Display.getWidth(),Display.getHeight()-3);//here we scroll the inner vertical
setExtent(Display.getWidth(),Display.getHeight()-3);
}
}
//Write all the code here;
subver.setpadding(1,0,0,0);
vfm_main.add(subver);
add(vfm_Main);
Like this Image:

I too faced the same issue once. I fixed it by using 2 field managers like this.
VerticalFieldManager mainManager = new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR )
{
public void paint(Graphics graphics)
{
graphics.clear();
graphics.drawBitmap(0, 0, Display.getWidth(), Display.getHeight(), backgroundBitmap, 0, 0);
super.paint(graphics);
}
};
//this manager is used for adding the componentes
VerticalFieldManager subManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR )
{
protected void sublayout( int maxWidth, int maxHeight )
{
int displayWidth = Display.getWidth();
int displayHeight = Display.getHeight();
super.sublayout( displayWidth, displayHeight);
setExtent( displayWidth, displayHeight);
}
};
I am having 2 EditFields in my login form with names Email: and Password:. Just below email I have login button. Suppose I come down till login, I can scroll back only till password field.The cursor fails to reach Email field. In simulator, I tried using arrow keys as well as trackpad. Please help how to scroll back to first editfield
AbsoluteFieldManager ab = new AbsoluteFieldManager();
add(ab);
new SeparatorField();
et=new EditField("Email-id:","");
pwd=new PasswordEditField("Password:","");
ab.add(et,35,110);
ab.add(pwd,35,150);
I am using AbsoluteFieldManager and developing for OS 6.0. I want the loginscreen to look like facebook login page.
Kindly let me know what can possibly be the reason for not able to scroll up
Maybe it is a RIM bug with the AbsoluteFieldManager. Never used it before so I don't know about it. You can create a work around to solve this problem. Find it below:
et=new EditField("Email-id:","");
pwd=new PasswordEditField("Password:","") {
protected int moveFocus(int amount, int status, int time) {
int cursorPosition = this.getCursorPosition();
if ((cursorPosition == 0) && (amount < 0)) {
et.setFocus();
return 0;
}
else {
return super.moveFocus(amount, status, time);
}
}
};
In this way, when you arrive to the first element in the password edit field, you will oblige the email field to get focused. This will work for you as a work around.
Another way to solve the problem is to add the two fields in an horizontal field manager, in that way I guess this will work for you for sure. If not use the first method. You can find below the code for HorizontalFieldManager:
et=new EditField("Email-id:","");
pwd=new PasswordEditField("Password:","");
HorizontalFieldManager manager = new HorizontalFieldManager();
manager.add(et);
manager.add(pwd);
ab.add(manager, yourX, yourY);
It also may be a RIM bug. What OS do you use? Is it OS 5+? Do you use custom paddings/margins/borders for some of the UI elements on the screen (including the screen itself)? If yes, try to comment out any code that sets paddings/margins/borders to check whether this it the case.
You can use this code for your login page:
public class loginscreen extends MainScreen implements FieldChangeListener {
private int deviceWidth = Display.getWidth();
private int deviceHeight = Display.getHeight();
private VerticalFieldManager subManager;
private VerticalFieldManager mainManager;
public long mycolor = 0x00FFFFFF;
Screen _screen = home.Screen;
TextField heading = new TextField(Field.NON_FOCUSABLE);
TextField username_ef = new TextField();
PasswordEditField password_ef = new PasswordEditField();
CheckboxField rememberpass = new CheckboxField();
public ButtonField login_bt = new ButtonField("Login", ButtonField.CONSUME_CLICK);
public ButtonField register_bt = new ButtonField("Register", ButtonField.CONSUME_CLICK);
public loginscreen()
{
super();
final Bitmap backgroundBitmap = Bitmap.getBitmapResource("bgd.png");
HorizontalFieldManager hfm = new HorizontalFieldManager(Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR )
{
protected void sublayout(int width, int height)
{
Field field;
int numberOfFields = getFieldCount();
int x = 245;
int y = 0;
for (int i = 0;i < numberOfFields;i++)
{
field = getField(i);
setPositionChild(field,x,y);
layoutChild(field, width, height);
x +=_screen.getWidth()-381;
y += 0;//l17
}
width=_screen.getWidth();
height=48;//w19
setExtent(width, height);
}
};
mainManager = new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR )
{
public void paint(Graphics graphics)
{
graphics.clear();
graphics.drawBitmap(0, 0, deviceWidth, deviceHeight, backgroundBitmap, 0, 0);
super.paint(graphics);
}
};
//this manger is used for adding the componentes
subManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR )
{
protected void sublayout( int maxWidth, int maxHeight )
{
int displayWidth = deviceWidth;
int displayHeight = deviceHeight;
super.sublayout( displayWidth, displayHeight);
setExtent( displayWidth, displayHeight);
}
public void paint(Graphics graphics)
{
graphics.setColor((int) mycolor);
super.paint(graphics);
}
};
username_ef.setLabel("Username: ");
password_ef.setLabel("Password: ");
rememberpass.setLabel("Remember Password");
heading.setLabel("Please enter your credentials: ");
username_ef.setMaxSize(8);
password_ef.setMaxSize(20);
subManager.add(heading);
subManager.add(username_ef);
subManager.add(password_ef);
subManager.add(rememberpass);
subManager.add(new SeparatorField());
login_bt.setChangeListener(this);
register_bt.setChangeListener(this);
hfm.add(login_bt);
hfm.add(register_bt);
subManager.add(hfm);
mainManager.add(subManager);
this.add(mainManager);
}
public boolean onSavePrompt()
{
return true;
}
public void fieldChanged(Field field, int context) {
// TODO Auto-generated method stub
if(field == login_bt)
{
//do your code for login button click
}
if(field == register_bt)
{
//code for register button click
}
}}
What you have described is not normal behavior.
My conclusion is that your code has one or more bugs, in order to solve your problem you should modify your code to fix the bugs. You will then be able to scroll up and down through the various fields.
note: As this question stands it's not possible for me to be more specific about the exact bugs. So instead I will show you an example of the layout you described that would scroll properly and you can use as a default to determine which of your deviations have caused your bugs.
// inside MainScreen constructor
add(new EditField("Username:","",0));
add(new EditField("Password:","",0));
add(new ButtonField(buttonBMP,ButtonField.CONSUME_CLICK));
When the user hovers over editfield below the touch screen keyboard does not display. What is displayed is a white area that is same size as keyboard. This is an issue on BlackBerry Torch. I would expect the touch screen keyboard to appear correctly using below code ?
BasicEditField nameField =
new BasicEditField(
" "+Local.getInfo8()+ " : ", "", 100, BasicEditField.FILTER_DEFAULT)
{
private int iRectX = getFont().getAdvance(getLabel());
private int iRectWidth = backgroundButtonBitmap.getWidth() - iRectX - 4;
public int getPreferredHeight() {
return backgroundButtonBitmap.getHeight() / 2;
}
public void layout(int width, int height) {
//setExtent(width, getPreferredHeight());
super.layout(width, getPreferredHeight());
}
public void paint(Graphics g) {
g.setColor(Color.BLACK);
g.setBackgroundColor(Color.WHITE);
//g.drawRect(iRectX, 0, iRectWidth, 20);
super.paint(g);
}
};
On the display screen, the method sublayout was being overriden -
protected void sublayout( int maxWidth, int maxHeight ) {
super.sublayout( maxWidth, maxHeight );
setExtent(maxWidth,Constants.BACKGROUND_IMAGE.getHeight());
}
The line - setExtent(maxWidth,Constants.BACKGROUND_IMAGE.getHeight()); is causing the issue.
What I try to do is to simply change the height of an EditField.
This sounds pretty easy but I facing a problem that drives me crazy.
Here is my code:
public class CMainManager extends HorizontalFieldManager
{
EditField mtxt=new EditField(EditField.FOCUSABLE | EditField.FILTER_DEFAULT);
/* Constructeur */
public CMainManager()
{
add(mtxt);
}
public int getPreferredHeight()
{
return Display.getHeight();
}
public int getPreferredWidth()
{
return Display.getWidth();
}
protected void sublayout(int width, int height)
{
layoutChild(mtxt, 50, 500);
setPositionChild(mtxt, 0, 10);
mtxt.setBackground(
BackgroundFactory.createSolidBackground(0x000000FF));
setExtent(width, height);
}
}
The line layoutChild(mtxt, 50, 500); should set the width and height of my EditField. It does, but only with the width. The height is constant. If I set it to 500 I get the same result as if I set it to 10.
Any idea of what I'm missing ? because I'm sure this is a stupid error I'm doing...
Thanks
==edit
After jproffit help, I've understood what I did wrong. However now that it works (I can set the height) I have another problem. Here is me code:
private EditField m_Txt=new EditField(EditField.FOCUSABLE |
EditField.FILTER_DEFAULT) {
protected void layout(int width, int height)
{
setExtent(Display.getWidth(), m_TxtHeight);
}
public boolean isFocusable()
{
return true;
}
protected void onFocus(int direction)
{
super.onFocus(direction);
invalidate();
}
protected void onUnfocus() {
super.onUnfocus();
invalidate();
}
};
With this code I cannot manage the focus correctly. What do I forget ? I cannot see the cursor in my field.
Any idea ?
Thanks
You aren't telling it the dimensions to take, you're specifying the maximum amount of space it can take up. So when you tell it 10, 50, or 500, if it only want to use a height of 8 that's all it will be. You'll have to override layout() on the EditField if you want to control its dimensions as well.
Try doing like this..
create a custom editfield and inside the layout method
_editField = new EditField("", initialValueOfTextField)
{
protected void layout(int maxWidth, int maxHeight)
{
int myWidth = getMaxSize() * getFont().getAdvance("W");// define your req width
int myHeight= 50 // your required height
super.layout(myWidth, myHeight);
}
};
