Unable to define Radio Button Text field & unable to change column position

Hi,
While designing a screen in Screen Painter, I am unable to define Radio Button Text field as this option is not there in Graphical Element. And also I want to specify the starting position of column of that element different from the default value, but I am unable to define that because the field is non-editable.
Can any one please help me out.
Regards,
Koushik

Hi,
Please find below the sample program from ABAP docu :
PROGRAM demo_dynpro_input_output.
DATA: input TYPE i,
      output TYPE i,
      radio1(1) TYPE c, radio2(1) TYPE c, radio3(1) TYPE c,
      box1(1) TYPE c, box2(1) TYPE c, box3(1) TYPE c, exit(1) TYPE c.
CALL SCREEN 100.
MODULE init_screen_100 output.
CLEAR input.
radio1 = 'X'.
CLEAR: radio2, radio3.
ENDMODULE.
MODULE user_command_0100 input.
output = input.
box1 = radio1.
box2 = radio2.
box3 = radio3.
IF exit NE space.
    LEAVE PROGRAM.
ENDIF.
ENDMODULE.
Here radio1(1) TYPE c is defined within the program but in the element list there are RADIO1 element exist. One is actual radio button and the other is Radio Button Text.
I am not able to create that radio button text using same object name.
Please suggest.

Hide Button if Field Empty

I have a view which I create a new button. I'm using a JSONModel to bind data to the button like so:
var btnCall = new sap.m.Button('btnCall' { text: "{PHONE}",
     press: [oController.onCall, oController]});
Not all records have a phone number, in that case I want to hide the button (setVisible(false)). Can you folks provide or point me to an example that does this? In the view, I tried to read the button text with getText(), but it's empty, I think because the data is binded after the view renders. This seems so simple, but I'm missing something.
I should have prefaced, I'm new to MVC and OOP. Any help would be greatly appreciated.

I am wondering what would be the requirement for this? Is it for SplitApp Controls's 'Back' button in Detail page? For Phone an Desktop scenarios? If yes, there is an easy way to do that.
If not, you may do binding for the 'visible' property of the button. Example:
oControl = new sap.m.Button({
text: "{PHONE}",
   visible: {
path:"PHONE",
formatter: function(fValue) {
if (fValue)
       return true;
else
     return false.

Disable a text field

Hi,
A non-database text field in a block with 10 rows displayed. I want to programatically enable/disable an instance of this field belonging to the current record. I tried to use set_item_instance_property but there is no enable/disable property in this built-in. Any other way ?
Regards,
Suresh

Suresh,
As Baig said, you have to set the INSERT_ALLOWED, UPDATE_ALLOWED, NAVIGABLE properties TO PROPERTY_FALSE will work for you. Its almost like disabling the item.
SET_ITEM_INSTANCE_PROPERTY('<block_name>.<item_name>', CURRENT_RECORD, NAVIGABLE, PROPERTY_FALSE);
SET_ITEM_INSTANCE_PROPERTY('<block_name>.<item_name>', CURRENT_RECORD, INSERT_ALLOWED, PROPERTY_FALSE);
SET_ITEM_INSTANCE_PROPERTY('<block_name>.<item_name>', CURRENT_RECORD, UPDATE_ALLOWED, PROPERTY_FALSE);Regards,
Manu.

How to disable certain text fields in second tab based on the drop down selection from first tab?

My first tab contains a drop down menu which has two options
1. Personal info
2. Office info
The second tab contains all the information regarding Office and Personal Information. But I need to selectively disable certain fields based on the drop down in first tab.
For example,
The second tab consissts of all fields like
Name,
Age
Job title,
Office Location, etc.
And i dont want office related details to be displayed if I am selecting personal info in the first tab.
It would be really great if someone could send me the code for achieving this.
Thanks in advance.

Hi Vishnu
Can you check the List component in foundation/components ? I think "Build list using" works he same as your requirement. Check the listener they have used in dialog/items/list/items/ listFrom/listeners
"selectionchanged" : function(box,value){box.findParentByType('tabpanel').manageTabs(value);}
here the ExtJs will find the tabpanel with value you are selecting fromdropdown. The title of each panel should match with the dropdown values
Some queries
Disable values means you have to remove it from your CRX?
"values should become mandatory". for tab2? or tab3? - if tab2 and if it is a customized widget then u have to write it in your js only i think.
Thanks

Changing quiz button text

I am working on a series of tutorials and quizzes for our
client, I want to change the text on the "Next" button on the
quizzes. It appears easy enough, in the options, Next button text
field, I have entered what I want, but it still appears as "Next"
when I publish it. Am I an idiot?
Please help.

This may be a stupid question, but did you save the file
before you published? I have sometimes had instances of not saving
and publishing first and my changes are not reflected.
Also, if the buttons were already on the screen with the text
"Next" when you decided to change the button text, you'll need to
delete those buttons and then add them again. The text does not
update dynamically.
Worst comes to worst, you can manually change the button text
with a double-click or through properties...
Hope that helps.

Disable button when text field is empty

Hi
How can I disable a button in JDialog box when the text field is empty and enable it when the user gives some input.
Balaap

You will have to use a keyListener since the use is not able to type into a disabled TextField. Listen for KeyEvents, if you get one enable the TextField a fill it with the char of the pressed key.

Empty text field warning

I want to have a book printed from Aperture 1.5.4, but when I press the 'Buy Book' button, a dialog pops up:
"*Empty text field detected in book*
The book you are about to order contains an empty text field.
How do you wish to proceed? Cancel/Continue"
That's all very nice, to give me a warning like that, but how on earth am I going to find one invisible text field in a 50-page book full of colour photos??
Does anyone have a hint? How problematic is it to leave the text field in? Common sense dictates that an empty text field should not be visible in the printed book either, but knowing Apple's fickleness in book matters... can I be sure? I can generate and check the PDF of course, but I don't know if that's sufficient proof.
Thanks!

hi, prauz
sounds like there is a text box (unfilled) and you haven't typed nor pasted text into it.
it's not that the text field is invisible, it's there yet to be selected and filled in with your information. so it is visible. have another looksie at it, look for the default letters or "Title Information Here"...

Disable Backspace when in input text fields

Im trying to find a way to disable the keyboard backspace
button from going back a page in the site but allowing it to
function as a character delete when needed for typing in an input
text field of a form.
Strangely this problem only occurs for about a minute after
the page is opened....after that it then works correctly. You can
see what I mean by accessing the site's contact page
www.safetybusiness.co.uk
I have found two different sets of code to disable the
Backspace completely, but this then means it doesn't work at all
when wanting to delete in the text field.
Method 1:
<script type="text/javascript">
if (typeof window.event != 'undefined')
document.onkeydown = function()
if (event.srcElement.tagName.toUpperCase() != 'INPUT')
return (event.keyCode != 8);
else
document.onkeypress = function(e)
if (e.target.nodeName.toUpperCase() != 'INPUT')
return (e.keyCode != 8);
</script>
Method 2:
<script>
function checkShortcut()
if(event.keyCode==8 || event.keyCode==13)
return false;
</script>
<body onkeydown="return checkShortcut()">
Anyone know how I can overcome this?

The TextField class has a tab order property. You may want to
look into this. As for disabling the backspace key, you can grab
key presses from user input. I'm not 100% on this but you could use
Flash to test the key being pressed. If backspace is pressed, find
out the current object with focus (unsure of this part), if it's an
input box in flash, have flash handle it or if a text box doesn't
have focus, send it out to javascript to have it handle it.

Safari 3.0.4 (523.12) weird text field & delete button behavior

Just installed the software update (10.4.11), and now have a weird problem with Safari 3.0.4 (523.12).
When entering text into a text field _on a web page_ (i.e. NOT the address bar or the built-in Google search field), the screen scrolls when the space bar is pressed (oddly, a space IS entered into the text field).
Also, once a few pages have been visited, hitting the delete key makes the browser act as if the "back" button had been pressed!
What gives?
I tried disabling plug-ins (and restarting Safari) in case one of them was causing a conflict, but it didn't help. I also repaired permissions with Disk Utility. For clarity, I hadn't tried rebooting before launching Safari.
Is it possible to revert back to a previous version?

Hi,
Some other things to try:
- delete the Safari prefs file at /Users/YourUsername/Library/Preferences/com.apple.Safari.plist
- try resetting Safari via the Safari menu
- a test you can do to help narrow down things is to try Safari in another user account. This will help us to know whether your problem is local to your account or system wide. If you don't have another account you can use System Preferences -> Accounts -> \[+\] to create a test one (and \[-\] to remove it if needed)

LOV from text field vs. button

I have an LOV that works upon navigation to a text field. It works great. I now want to base it off a button instead. Can I do this, but keep it based on the data from the text field even though it is the button launching it?
Also, can I elimate or disable the Find button in the lOV? How do I do this?

I got it working now.
used the following code:
LOV lov = new LOV();
void jButton1_actionPerformed(ActionEvent e) {
lov.setDataItemName("infobus:/oracle/jstut/lOVRowSetlkupquad");
lov.setRestrictedQuery("infobus:/oracle/jstut/rowSetlkupquad/QuadLong", null);
lov.setTitle("Title of window");
lov.setSize(550, 300);
lov.show();
** note that lOVRowSetlkupquad is the lovrowset and not the lov.
** and note "rowSetlkupquad/QuadLong"
is the object in the rowset it is based on.
Still does anyone know how to eliminate the find button in the LOV box?
