box arround editfield
is it possible to have arround textfield boxes, how?
thaks advances
RIM API 4.2 has no classes to control the field borders.
Optionally, you can use the class javax.lcdui instead of rim.ui classes and draw your fields on canvas.

If you add a constructor that accepts a parameter of long style and has great (style) as the first operator, you should be able to create with the FIELD_HCENTER style bit and add it to a Manager honor this indicator (for example, VerticalFieldManager). Then it will be automatically centered horizontally by the parent Manager.
It is the same on FIELD_VCENTER and, say, HorizontalFieldManager.

TextField inside the dialog box?
I saw on games like brickbreaker. They have a dialog box to come and ask you to enter your user name. I tried a little differently, but I have not had luck with it yet. Can someone point me to a tutorial or just after a line or two of code on how to do it?
Thank you
In your TestDialog class, add this method:
public final class TestDialog extends Dialog{ private EditField userNameField; public TestDialog(String choices[], int values[]){ super("Enter a username", choices, values, Dialog.OK, Bitmap.getPredefinedBitmap(Bitmap.INFORMATION), Dialog.GLOBAL_STATUS); userNameField = new EditField("User Name: ", "", 50, EditField.EDITABLE); net.rim.device.api.ui.Manager delegate = getDelegate(); if( delegate instanceof DialogFieldManager){ DialogFieldManager dfm = (DialogFieldManager)delegate; net.rim.device.api.ui.Manager manager = dfm.getCustomManager(); if( manager != null ){ manager.insert(userNameField, 0); } } } public String getUsernameFromField(){ return userNameField.getText(); } }Then change your main class to use:
if(pw.doModal() == Dialog.OK){ System.out.println(pw.getUsernameFromField()); } -
Custom elegant EditField (textbox)
Hello!
I was wondering if there is a way to create cute user interface components for our applications. I would like to have something like this:
But the EditField BB is very very ugly. I tried a custom EditField of (http://www.blackberryforums.com/developer-forum/218757-custom-text-edit-filed-vertical-scroll.html)
But it looks like this:
It's completely is and ugly, not decent for any application. For cute, we should override the paint method and draw a Bitmap simulating a cute EditField?
public void paint(Graphics g) { super.paint(g); g.drawBitmap(0, 0,50, 50, Bitmap.getBitmapResource("profile.png"), 10, 10); //g.drawRect(0, 0, getWidth(), getHeight()); }If we paint a Bitmap with the height and width fixed, we will see it very small or big if the resolution is changed? For example, in "BOLD" curve with 320 x 240 or 480 x 360.
Thank you!
First of all - there is no built-in component like the one you want.
Second - the article you mentioned has a very harmful code that would avoid you best. I don't know what drunk monkey for the first time getManager () .invalidate () inside the paint, but this piece of code has found its place in more than one article of the BlackBerry UI on the ' Net. Avoid it like the plague.
Third - you need paint Bitmap image first, then call the super.paint. Otherwise, your bitmap image is painted on the letters!
Fourth - indeed, the image will be different on different screens. There is a drawTexturedPath method that allows all sorts of affine transformations and the tiles of the original Bitmap. It is quite effective, but could distort Bitmaps. There is also the drawShadedFilledPath, which creates a sort of background gradient. Finally, there are all sorts of classes useful net.rim.device.api.ui.decor package (available since 4.6).
And finally, the answer to your first question - Yes, there are several ways to create cute user interface components. Here's the complete code for my experience with rounded edge text boxes (it fate multi-line, scrollable vertically)-you can experiment with colors and other things there.

I'm trying to create a text using the EditField box, when you type a character his listener is invoked. This must be done each time a character is entered.
I try to achieve an effect when a user types in the search box start automatically, for example a list of names, when the user starts typing, it will find and bring back what the user types, so if C is entered all names starting with C would return, if they then type CO, all names starting with "CO" will be returned.
I had no problem creating the text box, I tried to add the handler in the following way,
FieldChangeListener bhandler = new FieldChangeListener() { public void fieldChanged(Field field, int context) { System.out.println("woohoo"); } }; search.setChangeListener(bhandler);Any help would be appreciated.
Try this
Search for EditField = new EditField ("search for:",");
search.setChangeListener (new FieldChangeListener() {}' Public Sub fieldChanged (field field, int context) {}
System.out.println ("Woot");}
});

Hello!
I had a problem of design. I did something I thought I would work, but I think that I am so close to get it. I have 2 is the image I updated my EditField as boder when unfocus the image has a WHITE background and what door another color. I have a few lines in unfocus and the development of the code field method and I put the border with these images. But when I run on the Simulator, the field has a white rectangle inside. So, I added a few lines and I put a background color when the field is developed. But I got something like that.
Unfocus:
Focus:
How can I erase this white part? or maybe is there something I have missed?

Hello! Thanks for your review!
Well, I create a custom EditField and here is a part of the code:
private int mHColor = -1; public void setHightlightColor(int color) { mHColor = color; } protected void onFocus(int direction) { invalidate(); setBorder(BorderFactory.createBitmapBorder(new XYEdges(4, 7, 4, 7),Bitmap.getBitmapResource("img/box.png"))); } protected void onUnfocus() { invalidate(); setBorder(BorderFactory.createBitmapBorder(new XYEdges(4, 7, 4, 7),Bitmap.getBitmapResource("img/boxu.png"))); } public void paint(Graphics g) { if (-1 != mHColor && getManager().isFocus()) { g.setBackgroundColor(mHColor); g.clear(); } int prevColor = g.getColor(); g.setColor(prevColor); g.clear(); g.setGlobalAlpha(200); super.paint(g); }And in my screen, I called like this:
_inputField.setHightlightColor(0xFFFFBD);/// FFE9AF _inputField.setBorder(BorderFactory.createBitmapBorder(new XYEdges(4, 7, 4, 7),Bitmap.getBitmapResource("img/boxu.png")));You see how I use a bitmapborder. I create 2 images: one with white background and one with yellow background.

How to convert the Editfield value chain
Greetings
Please help me to convert the editfield in sting.
with the help of toString (), it does not convert it to a string.
Help, please

Anthony singh
arkadyz is located...
but you must put this line in an event thread... because you enter the value in an editfield dynamically (at runtime) he must go and look after that the value has been added...
As you can use a button... When you click on it, then the value is extracted from the help:
final String text = SmsField.getText ();
and your dialog box appears...

Question of the development of EditField and LabelField in HorizontalFieldManager
I actually want a custom editfield (a label with a textbox), when he got focus on this textbox draws a border of climax, and I want the label got the same effect, however, I drew a border outside the text easily because of the text box could receive focus , here is my code:
public class MyTextField extends EditField { public MyTextField() { super(); } public void layout(int width, int height) { super.layout(width, height); } protected void paint(Graphics g) { if(g.isDrawingStyleSet(Graphics.DRAWSTYLE_FOCUS)) { setBorder(BorderFactory.createRoundedBorder(new XYEdges(6, 6, 6, 6), 0x186DEF, Border.STYLE_SOLID)); }else{ setBorder(BorderFactory.createRoundedBorder(new XYEdges(6, 6, 6, 6), Color.GRAY, Border.STYLE_SOLID)); } super.paint(g); } }And I use this code to show in screen
HorizontalFieldManager hfm=new HorizontalFieldManager(); LabelField label=new LabelField("something"); MyTextField text=new MyTextField(); hfm.add(label); hfm.add(text); add(hfm);Is there a way to implement that when the textbox has got the update at the same time also changed the color of the text of the label.
set a Boolean flag that you record in paint, set it on the ground (from outside) and invalid call to redraw.

Instead of getClippingRectangle(), just try calling getHeight() and getWidth() on the field to get your height and width.
Something like this:
graphics.setColor(Color.GRAY); graphics.drawRect(0,0,getWidth(),getHeight);

Newbie - editfields put in shape on the screen
HI all, it seems that it should be simple.
My class screen extends screen and adds a bunch of EditFields. How to get the labels to align vertically along the left margin of the screen and the data input fields line up vertically along the right edge of the screen? Please, look at the default AppointmentItem for what I'm trying to accomplish.
Thank you, Steve
There is no stock management that does what you want (if I understand the question).
Fields of change all take them across the width of the default view; the label takes as much as he needs and the text box takes the rest.
When your right - justify the text box, how much space you take and what direction should the text fill the input box?
I think that you might be looking at the date fields on the screen that you mention?
In any case, it will take you either write your own editing field custom, one of those that exist, patch or extend something upward with a HorizontalFieldManager containing a label separate fiekd and the input field (of the sort that you can justify the two fields independently).
