How do I get Watermark to show in the Edit drop down in LR 3.4?

There is no Watermark function under the Edit drop down box in my Lightroom v 3.4 How do I get it to appear so I can use it?

Yes my system is Mac based, and I did locate a Watermark check box in the Print where I was able to install a watermark. However when I open the Edit drop box at the top, does not show a Watermark Edit selection.

Editing Drop Down Menus in Contribute

I have a client who is using contribute and wants to edit
drop down menus. These drop down menus link to individual pdfs and
she changes the names of the pdfs on a regular basis and wants to
update these links in the drop down menus. The site was created in
Dreamweaver. In role preferences of Contribute I turned on the
allow unrestricted editiing which allows form elements to be
edited. However I cannot figure out how to change the drop down
menus. Is there any way to edit the drop down menus fields in
Contribute?

Create a SSI (with PHP f.i.), best in de root of the site,
considering the way Contribute is handling linking.
Call the file something like menu.inc.php.
Provide your client with the url to menu.inc.php in the
Bookmarks or explain the Choose-button in Contribute to open the
file menu.inc.php.
Keep the file simple (ul/li or p) .

How to modify the size of the editable drop down

I have used the editable drop down list which works perfectly. The only problem i find is that it has a static width, unlike a regular select/option list that adjust according to the lengh of the data that is in it. Is there any way i can adjust the width of the editable drop down list. Thank you.

try removing the width completely...leave that field blank

How does one come to know this..drop down in ALV in WD

Hello Friends,
                      I had a requirement of adding a drop down in ALV, i eventually got it but I have some questions about it
I used the following code and got the drop down
lr_column = lr_column_settings->get_column( 'BWART' ).
CREATE OBJECT lr_input_field
    EXPORTING
      value_fieldname = 'BWART'.
lr_column->set_cell_editor( lr_input_field ).
DATA : LR_DROPDOWN TYPE REF TO CL_SALV_WD_UIE_DROPDOWN_BY_KEY.
CREATE OBJECT LR_DROPDOWN EXPORTING SELECTED_KEY_FIELDNAME = 'BWART'.
LR_COLUMN->SET_CELL_EDITOR( LR_DROPDOWN ).
DATA: LT_VALUESET TYPE TABLE OF WDR_CONTEXT_ATTR_VALUE,
LS_VALUESET TYPE WDR_CONTEXT_ATTR_VALUE,
LR_NODE TYPE REF TO IF_WD_CONTEXT_NODE,
LR_NODEINFO TYPE REF TO IF_WD_CONTEXT_NODE_INFO.
LR_NODE = WD_CONTEXT->GET_CHILD_NODE( 'RETURN_NODE' ).
LR_NODEINFO = LR_NODE->GET_NODE_INFO( ).
LS_VALUESET-VALUE = '973'.
LS_VALUESET-TEXT = '973'.
APPEND LS_VALUESET TO LT_VALUESET.
LS_VALUESET-VALUE = '222'.
LS_VALUESET-TEXT = '222'.
APPEND LS_VALUESET TO LT_VALUESET.
LR_NODEINFO->SET_ATTRIBUTE_VALUE_SET( EXPORTING NAME = 'BWART' VALUE_SET = LT_VALUESET ).
My question is ... how does 1 know which class to use? how to use that class... most of concepts about OOPS are clear.. but i still cant figure out how does 1 find out which class to use.. is it all by expericence..

In short: Yes, by experience. Then again, for WD4A there is a class for each UI-Element available. Once you know this, you can easily search se24 for CLWD<UI-NAME>* or the like.

Editable drop-down problem.

Hello all,
Here's the issue. I have an editable dropdown list/menu in a table. The table is hidden upon page load. When the user clicks the link to open the table, the editable drop down is only 1 or 2 pixels wide. How do I get the editable drop down to open at the prescribed 300px?
Here's the code:
<select name="CGSector1" id="CGSector1" wdg:subtype="DynamicInput" wdg:type="widget" wdg:recordset="rsCGSectors" wdg:displayfield="CGSectors" wdg:valuefield="CGSectors" wdg:norec="150" wdg:singleclickselect="yes" wdg:defaultoptiontext="no" wdg:restrict="No" wdg:ext="php" style="width:300px" wdg:fakeattribute="<?php WDG_registerRecordInsert("connStr_xxxxxx", "rsCGSectors", "CGSectors", "CGSectors");?>"></select>
Thank you.
Brian

As this issue is not directly related to ADDT, but assumingly rather to e.g. aspects like the defined (if any) width of the initially hidden table, please give a link to the complete page code (or a live page) to help others with spotting the possible reason for this.
However it should be mentioned that ADDT´s "editable dropdown" is generated on-the-fly using some proprietary AJAX functionality as well (including the style rendering), so maybe the style setting you defined here just gets ignored when the surrounding "container" (aka the table) gets hidden by - for instance - using features from another AJAX library like JQuery which is certainly incompatible with than ADDT´s own AJAX implementation.
Cheers,
Günter

Editable Drop-Down List

Hello!
I am using Dreamweaver's Editable Drop-Down List
Application panel, Server Behaviors > + > Developer Toolbox > Form Controls > Editable Drop-down
Which has been a GREAT option, but I need to add on 1 option, when I am about to ADD an item to the list, all you can do is add 1 item to 1 column in a database.
Database Struture:
listid   userid   listItem    listitemValue
But all I can get it to update is listItem I need to be able to when the button, "ADD THIS" is pushed, that I can add a value to USERID also, is this possible? I tried diving deap into it, but some certains things I just didn't understand that far down.
Any help would be greatly appreciated!
Cheers, and thank you in advance.

Ok I completely misunderstood. Sorry for the confusion. I'm afraid I may not be much help on this particular function. Some functions I've really torn apart and modified, this is not one of them.
This does not look like one of the more simple functions to change unlike some others,
Before trying to go into lengthy info on how to break it down, is there any chance the info you are trying to update is some type of default name or incremental name, something than can be hard coded? ..or is it unique like a visitor, so you are pulling down each time? Ex: User1, user2    vs.   sally101, david2009, etc.
IF not, there are a several lines of variable setting and function modification to change at first glance.
I can look into later, but the variables are not even in the same insert function page.
Here is the Key line in WDG_recordsetInsert.php,
$sql = 'INSERT INTO ' . $vars['table'] . ' (' . KT_escapeFieldName($vars['updatefield']) . ') VALUES (' . KT_escapeForSql($text, 'STRING_TYPE') . ')';
but the vars appear to come out of an array in 'WDG_functions.inc.php : here is the function variables being set for the insert function above
$WDG_sessInsTest = &$_SESSION['WDG_sessInsTest'];
     $WDG_sessInsTest[] = array(
          'conn' => $connectionName,
          'rsName' => $rsName,
          'table' => $sqlTable,
          'idfield' => $idField,
          'updatefield' => $updateField     );
This array (at first glance) could be modified, but I can't promise that the vars will carry through because I don't see exactly where this array is being used again.
As I mentioned, if the values you need are something you could hard code and increment, you could easily modify the 'insert to' function above.
I would also toy around with some $_POST data and Session data vars and see if you can drop those straight into the sql statement above.
Sorry I can't be more help on this one.

Editable drop-down control???

hi,
How can i get editable drop-down control in my JSP page.
is it possible thr' java script or swings or something else???
plz help.
sam

This should do the trick. Just pass the value and the text as parameters to the function.
<html>
<body>
<form name="dropDownForm">
Value: <input type="text" name="optionText">
Text: <input type="text" name="optionValue">
<input type="button" value="Add option" onclick="addOption(document.dropDownForm.optionValue.value, document.dropDownForm.optionText.value)">
<br><br>
<select name="dropList"></select>
<script>
function addOption(value, text)
var position=document.dropDownForm.dropList.length;
document.dropDownForm.dropList.options[position]=new Option(value,text);
</script>
</form>
</body>
</html>

Editable drop downs and safari

Editable drop downs don't seem to show the "Add This" button in Safari on the Mac. It works in Firefox on the Mac and all Windows browsers. Does anyone have a fix for this?
Thanks

LMatts,
This may be a CSS issue. You may have to edit the ADDT CSS. For testing purposes, try removing the CSS formatting from the HTML and see what displays. Remove the class="KT_tngtable" and class="KT_th from the table code that ADDT forms create and see what it looks like.

Editable drop downs in sharepoint?

Is there any way to create "editable" drop downs for a list in sharepoint? Meaning that if the value is not listed, the user can add it right away.
Thanks,
Carlos Roberto Vargas

You mean a SharePoint list forms right? In the settings for the choice column in the list settings there is an option that lets you specify whether your users can add their own choices. Enabling this will allow users to add their own
terms.
Or you can set the choice column as a look-up list and let them add additional options to the look-up column.

Hi Shashi,
Your code looks okay. Debug & check if everything goes fine and all the required list of values getting bound to node.
Is any code after this logic, which sets data to table ? if so, that logic is wiping out the drop down list values from context node.
Final check point:
Read the context node 'TABLE' and fetch records into internal table in WDDOMODIFYVIEW( ) method to make sure that, every row of your table contains the drop down list entries in "LEAVE_VALUES" attribute
Hope this helps you.

Rama

Drop Down in ALV ABAP and NOT in OO - ABAP

Hello Everyone....
I m workin on an ALV which is in simple ABAP and not in OO-ABAP. There is some selection criteria on the first screen , as soon as the user fulfills the requirement an ALV GRID is displayed in which the last column is editable.
But the Problem is that i wanna make that editable field in ALV as drop down which would contain values from the database table.
Suggest me some method , so that i dont have to do much changes in my code .
A Sample code will be very benificial .
Thanx n Regards,
Harpreet.

Hi Harpreet,
[compiled from sap online help - always a good chice]
To make an input/output field into a list box, you must set the value L or LISTBOX in the Dropdown attribute in the Screen Painter. The visLg attribute determines the output width of the list box and the field. You can assign a function code to a list box field. In this case, the PAI event is triggered as soon as the user chooses a value from the list, and the function code is placed in the SY-UCOMM and OK_CODE fields. If you do not assign a function code, the PAI event must be triggered in the usual way that is, when the user chooses a pushbutton or an element from the GUI status.
If you have assigned a list box to an input/output field, you can use the Value list attribute of the screen element to determine how the value list should be compiled. There are two options:
Value list from input help (recommended)
If you do not enter anything in the value list attribute, the text field uses the first column displayed in the input help assigned to the screen field. The input help can be defined in the ABAP Dictionary, the screen, or a POV dialog module. It should be laid out in two columns. The key is automatically filled.
Value list from PBO modules (not recommended).
If you enter A in the value list attribute, you must fill the value list yourself before the screen is sent (for example, in the PBO event) using the function module VRM_SET_VALUES. When you do this, you must pass an internal table with the type VRM_VALUES to the import parameter VALUES of the function module. VRM_VALUES belongs to the type group VRM. The line type is a structure consisting of the two text fields KEY (length 40) and TEXT (length 80). In the table, you can combine possible user entries from the KEY field with any texts from the TEXT component. You specify the corresponding input/output field in the import parameter ID.
Examples

       EXPORTING
            retfield        = 'CARRID'
            value_org       = 'S'
       TABLES
            value_tab       = itab_carrid
       EXCEPTIONS
            parameter_error = 1
            no_values_found = 2
            OTHERS          = 3.
IF sy-subrc <> 0.
ENDIF.
ENDMODULE.
The next screen (statically defined) for screen 100 is 100. The only input field on the screen is the component SDYN_CONN-CARRID. Its Dropdown attribute is set to L, and it has the output length 20. The Value list attribute is empty, and it has the function code SELECTED. The function codes of the buttons EXECUTE and CANCEL. CANCEL are defined in the GUI status as having the function type E.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
MODULE status_0100.
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
MODULE user_command_0100.
PROCESS ON VALUE-REQUEST.
FIELD sdyn_conn-carrid MODULE create_dropdown_box.
Users cannot enter any values into the screen fields. When they choose the input field on screen 100, the system displays a list box. The Value list attribute is empty, so the system launches the input mechanism. In this case, the event block PROCESS ON VALUE-REQUEST is created in the screen flow logic. This event block controls all other mechanisms. A two-column internal table is filled in the appropriate dialog module and passed to the input help using the F4IF_INT_TABLE_VALUE_REQUEST function module. The system inserts the two columns of the table into the list box.
When the user chooses a line in the list box, the PAI event is triggered using the function code SELECTED and the value in the first column of the internal table is copied to the input field.

Clemens
