Using TextField

Hi,
I use TextField to get an 8-digit value from the user. I have the following questions:
1. How do you tell TextField to stop editing and make the keypad dissapear?
2. Where is the TextField data stored and how do you retrieve it?
3. How do you limit the max. number of value entry to 8-digit using TextField or other interfaces?
Some code snippets would be helpful.
Thanks.

if u mean entered text by the "textfield's data", it is in 'text' member of the textfield class.
e-g u can get it as;
myString = myTextField.text;
Set an event handler for the textfield as;
[myTextField addTarget:(id)self action:@selector(symbolTextChanged) forControlEvents:UIControlEventEditingChanged];
In 'symbolTextChanged' method, u can check the length of the text entered as the user types a character, as it exceeds 8, make the keyboard disappear as;
[myTextField resignFirstResponder];

Using textfield in screen to navigate to next screen.

Hi experts,
I am designing a screen in screen painter. There is a Text field in the screen which is double click enabled. Now i want to use this text field to navigate to next screen when it is double clicked. How to do it. Please help.
Regards.
Vaibhav Tiwari.

Hi,
In the Flow logic of your screen under the PAI Event in the default module user_command_xxxx INPUT , use case statement to check for the sy-ucomm value for the double-click event and check then check the GET cursor value, if it is the text field(double-clicked enabled textfield), then call whatever screen you want to.

How to use TextField to add two numbers and show the result.

hi everybody
i would like to use JTextField to get addtion of two Numbers,
for example i am trying to type any integer numbers in JTextField like 7
and press JButton, called( +) to add anthor number like 7 and press JButton called(=) to get addtion fo
7 + 7 = 14, at same JTextField.
so there will be two buttons, one for (+),other for (=).
i have implement ActionListener in (+) button ,to get Text from JTextField (with getText() method),
now how do i use same getText() method to get the next number that i will add it with previous number in
(+) button and get the result whenever i press (=).
1-type integer number like (4) in TextField.
2-press addition button(+) to get text by using getText() method and clear TextField.
3-type anthor integer number like(6).
4-press (=) button to get the number (6) by using getText() method, calculate 4 + 6 and show the result at same TextField (10).
i hope it is so clear
thank u in advance for any advice and suggestion.

Use your first button to
String x = JTField.getText();
int y = Integer.parseInt(x);
this will get your first value on your + button. Make sure you initialise the int beforehand incase nothing is put in (ie error prevention) then clear the JTField prob using setText(""). Repeat the process for the = button using different variables and add them normally and output the result.
If your putting more than 1 arithmetic button on the GUI then you'll need to distinguish between them!!!

Can I use textfield in an application with low level api?

Hello !
I am developing a mobile application using the low level api.
I have to use it, because I do a lot of coloring.
But I want to use high level textfields as well. Is there any way
to include them in my application without using forms?
Does any one know, why J2ME designer's have limited the access
to the TextField's paint()-method? That's why I cannot inherit
from TextField and overwrite the paint() as I would like to do.
Thanks.

Unfortunately no. You cannot mix both high and low level on the same screen. You'll probably have to draw it out yourself and capture user input, unless you're willing to use textboxes.
Or.. i suppose you can try using customItems for all your "coloring" instead?

Problem using TextField & CustomItem in a Single Form

Hi all, I developed a mobile appliction with j2me. I append a customItem and then a textField in a Form. And when testing in Nokia N95, i'm getting a weired bug.
The bug ::
when i try to write the first character of the second line in that text field, an extra character in appended in that textField automatically (the extra character is the first character of the pressed button).
i tried it in a form having only one textField. the bug doesnt exist there.
Please help me with this matter. Is there any alternate?

Hi,
I am having the same problem. The tripple tap doesn't work when you type from one line into the next.
Was any workaround or fix ever discovered?

Using textfield for signatures

Hi,
I'm using a form on a third party vendor's application.
I have to use a text field to capture a signature as opposed to Adobe's signature field.
When I do this, however, I get some spurious data that appears under the signature.
The text is the same every time, even with other forms. I'm trying to determine if this is a known issue with Adobe or with the vendor.
thanks,
Paul

OK, I figured it out.
I went to the object window, select Field tab, then Presence and changed 'Invisible' to 'Visible'

Use textfield in actionperformed function

Hello,
I want to extract value of e.ActionCommand where e is an object of ActionEvent
in a TextField in the main function in the actionPerformed(ActionEvent e) function.
How and where do I add the TextField in the main function. I created a Frame inside the main function

public static void main(String args[])
Frame f1=new Frame("Frame Window");
menushow x; //Applet class instance
x=new menushow();
x.init();
MenuBar mb;
mb=new MenuBar();
f1.setMenuBar(mb);
Menu test=new Menu("File");
mb.add(test);
MenuItem c1=new MenuItem("New");
ActionListener listener=new ActionListener()
public void actionPerformed(ActionEvent e)
String str4;
str4=e.getActionCommand();
c1.addActionListener(listener);
test.add(c1);
f1.setLocation(50,50);
f1.setSize(700,500);
f1.add("Center",x);
f1.show();
}

Using textfield content for math

// set variable as numbers
var monthly_num:Number = 0;
var ttl_num:Number = 0;
var ttl_rev_num:Number = 0;
// user-entered numbers from an Input textfields
monthly_num = monthly_txt.text;
ttl_num = ttl_txt.text;
// Multiply two user-entered number together to get new
result
ttl_rev_num = ttl_num*monthly_num;
// Attempts to assign numbers typed into textfields to
numeric variables causes errors.
1067: Implicit coercion of a value of type String to an
unrelated type Number.

you must 'cast' the text string as a number as in:
monthly_num = Number(monthly_txt.text);
ttl_num = Number(ttl_txt.text);
ttl_rev_num = ttl_num*monthly_num;

Using textField input as parameter to SQL Query

Hi,
Only a newbie can ask a quetion like this. I need my user to input a value in a text box, click a button and see the results of the Query displayed. I can do that if I bind a Dropdown box to a table, but since the table is huge, my page will slow down.

Hi,
Exactly,
The below peice of code may give u an idea.
this.getSessionBean1().setid(textField1.getValue().toString());
where id would be bean property.

Query for create manual tabular form using apex collection using item textfield with autocomplete

can we create a manual tabular form inside item textfield with autocomplete ?
how it is possible?
with Apex_item API used for this item.
i used this code for creat cascading select list

I understand that the add row button is currently doing a submit.
To not submit the page you need a dynamic action on the page.
Does the javascript function addRow do what you want?
Otherwise have a look at the following two threads Add row in manual tabular form using dynamic action and Accessing Tabular Form & Add Elements to Collection without Page Submit.
You're process could be something like:
Add the new values to the collection using the idea's in the second thread and at the same time add the new row.
And as second action refresh your tabular form.
If you get stuck set up what you have done on apex.oracle.com using the tables from the demo application.

Having problem with setting variable on a textfield

I'm using createTextField to create a textfield. I have also created a input textfield with a variable called textline1 (I don't create the inputfield with as).
I want to display the letters in the created textfiled that I'm typing in the input field. So this in my AS coed:
_root.createTextField("text1",1,100,100,300,100);
text1.variable = textline1;
format1 = new TextFormat();
format1.color = 0xff0000;
format1.size = 50;
format1.bullet = false;
text1.setTextFormat(format1);
but it doesn't work. So anyone see the problem?
(sorry for bad english)

i think you're going to have more problems if you continue using textfield variables. you should not use them. just use the text property of the textfield to reference its contents.
but, if you want to continue, use:
var tl:MovieClip=this;
fontsize=20;
myInputText_txt.onChanged = function(text1:TextField) {
_root.myText_mc.createTextField("text_txt",1,100,100, 100,100);
_root.myText_mc.text_txt.variable = tl["text2"];
text2=text1.text;
format1 = new TextFormat();
format1.color = 0xff0000;
format1.size = fontsize;
format1.bullet = false;
text_txt.setTextFormat(format1);
p.s. please mark this thread as answered.

Which is better to use in alv functions or oops concept

hi,
actually some people are using function modules
and some are using oops concept
which one is better
could anybody suggest
thanks,

I assume you've found TLFTextField in Flash Pro (I can't remember if Flash Builder made a TLFTextField class or not). Anyway, if you're considering using Flash Pro, here's some background on the TLFTextField class:
This class was created primarily for backwards compatibility with Classic Text coding. If you used Flash Pro CS 4 or earlier versions, and you wrote ActionScript for your text objects, you were using TextField objects. So, when you upgraded to CS 5, and you decided to convert all your old Classic text objects to the new TLF objects, all your code would have broken were it not for TLFTextField class. TLFTextField implements the TextField API so that your existing TextField code can be used in the TLF environment.
So, if you're an ActionScript programmer who is already comfortable programming using the TextField API, it certainly makes sense to continue doing so but using TLFTextField objects. However, if you want to take advantage of the new TLF features, the old API doesn't really give you the ability to do that. So, the TLFTextField provided a new API:
function get textFlow():TextFlow;
The TextFlow class is the top level class of the TLF model objects. Using that object, you can then set attributes on your text just as if you were working with TextFlow in Flash Builder. So, in essence, TLFTextField provides backwards compatibility, continued use of the familiar API set, and access to the TextFlow model class.
Another nuance to be aware of is that if you choose to embed fonts, TLF requires the newer "DF4" (for DefineFont4, based on the SWF Tag name) vs. the older "DF3" fonts that TextField requires. For text on the stage, Flash Pro will do all the tricky work for deciding when to embed DF3 and when to embed DF4 fonts, but just be aware that mixing Classic text and TLF text when using embedded fonts can cause a "double tax" on your SWF size because it may embed the same font both as DF3 and DF4.
Good Luck!

TLFTextField or TLF, which is better to use in CS5?

Hi,
I have been developing content using TLF with CS4 and in Flash Builder. Recently when I switched to CS5, there was this cool TLFTextField. So now I wonder, TLFTextField or TLF, which is better to use in CS5? Almost all of my text will be dynamically generated. Please share your thoughts - possibly with pros and cons.

Not able to use TextBox with Border (JavaFx 2.0)

final BorderPane border = new BorderPane();
Label label1 = new Label("Name:");
TextBox textBox = new TextBox ();
HBox hb = new HBox();
hb.getChildren().addAll(label1, textBox);
hb.setSpacing(10);
border.setCenter(hb);
root.getChildren().add(border);
The above code is not working as expected as the text box is in disabled state always. I am new to JavaFx 2.0 and any help/guidance is highly appreciated. Thanks in advance.

It works for me.
Update your javafx2.0 sdk.
TextBox is deprecated.
Use TextField textBox = new TextField ();
