How to enable/disable a button in Photoshop panel?

Anyone know how you'd create the proper code in a Photoshop extension panel so that certain buttons in the panel could be enabled or disabled dynamically as needed?

Hi Sonunew2flex,
Write one public function in main application file as below...
// In main application file
public function changeButtonDisableStatus(bool:Boolean):void
     yourNuutonId.enabled = bool;
//In your hear renderer do this
if(cb.selected=true)
   Application.application.changeButtonDisableStatus(true);
else
   Application.application.changeButtonDisableStatus(false);
Thanks,
Bhasker

How to Enable the SAVE button in the Menu Bar of the Invoice Document.

Hi.
How to Enable the SAVE button in the Menu Bar of the Invoice Document as it is disabled for me.
I would like to save the Invoice document in PDF format.
Regards
Irfan

Hi,
Normally, for the archiving or generation of the invoice document in PDF format is handled by maintaining the output records through VV31/VV32 with the relevant printer, storage mode ( 3- print and archive or 2- archive only ), no. of messages ( means no of copies ) in the communication method.
Then when you click the print button through VF03 in the print options pop-up you get a print at the physical printer and at the same time an archived copy ( PDF copy ) attached with the document.
So, please make sure the output records are fine to allow a PDF copy generated and then try to print and check in VF03 by entering into the billing document.
Hope this helps you.
However, from the print preview you normally would not be allowed to save or print.
Regards,
Ram

Enable/Disable a button

I was wondering how could i disable a button until another
action has been accomplished before enabling a button. Is there
anyone that could help me on this?

This might help - it's a script I picked up somewhere a few
years ago that disables a button once it's been pushed, then if the
page has not been submitted after a few seconds, it will flash an
alert to the user telling them to hold their horses. It's helped
cut down on people resubmitting things.

When I navigate web with Firefox my Thinkpad trackpoint center button is not working. With other web browsers it works well. Where is the problem in firefox, how to enable TrackPoint center button?

I have exactly the same settings in Options (in both computers)
for history, these 2 add-ons and all other stuff in Options. The only difference is that on 1 pc sessions can be saved and closed tabs can be reopened, on other main pc they stopped to work. + no any other add-on that does similar things works on this pc.
It is also interesting that I can reopen closed visited sites from History Panel, but not by pressing the Button. For now I only manually bookmark links to a temporary folder.
Recently (some 2 month ago) I pressed x and Firefox closed all tabs without saving them without displaying save & quit pop up.
so I changed 4 settings in about.config
browser.tabs.warn on close true
browser.warn on quit true
browser.warn on restart true
browser.show.quit warning true
but the problem with sessions appeared only 1 week ago.
So I guess the problem is not with the History settings or other settings. Seems that something responsible for button or for storing info about tabs/sessions got corrupted. :(

Hi,
Try this code.
First create a attribute with the name readonly of type wdy_boolean and bind it read_only property of input field of which is you want to enable or disable.
Next go to Init method.
Set the readonly value as 'X'.
DATA lo_el_context TYPE REF TO if_wd_context_element.
     DATA ls_context TYPE wd_this->element_context.
     DATA lv_visible TYPE wd_this->element_context-visible.
*   get element via lead selection
     lo_el_context = wd_context->get_element( ).
*   @TODO handle not set lead selection
     IF lo_el_context IS INITIAL.
     ENDIF.
*   @TODO fill attribute
*   lv_visible = 1.
*   set single attribute
     lo_el_context->set_attribute(
       name = `READONLY`
       value = 'X').
After that Go to the Action ENTER.
First read the input field ( first input field, which is value entered field) , next give a condition
if input value is not initial then set the readonly value is ' '.
DATA lo_nd_input TYPE REF TO if_wd_context_node.
     DATA lo_el_input TYPE REF TO if_wd_context_element.
     DATA ls_input TYPE wd_this->element_input.

*   navigate from <CONTEXT> to <INPUT> via lead selection
     lo_nd_input = wd_context->get_child_node( name = wd_this->wdctx_input ).
*   @TODO handle non existant child
*   IF lo_nd_input IS INITIAL.
*   ENDIF.
*   get element via lead selection
     lo_el_input = lo_nd_input->get_element( ).
*   @TODO handle not set lead selection
     IF lo_el_input IS INITIAL.
     ENDIF.

How to enable touch screen stylus in photoshop: Dell Inspiron 13: windows 8?

You don't need to enable anything. For it to work you need a touch screen display and a pressure sensitive pen. Not a capacitive pen like those used on a iPad.
A capacitive pen will work with the interface but not the brush tool.

How does one disable a button in the web UI? I am trying to disable the edit button in the web UI for Accounts. What are the steps to take in order to accomplish that?

Hi Abdul,
Locate the Toolbar group group for that application. It should be ACC_OIC01 in your case. You can deactivate a specific button (event) under the toolbar group.

Just adding on to Nameeta's post, there is a supress download checkbox in the advanced setting s link(Settings -> Advanced Settings) on the client, this will supress downloads for all syncbos and not just for any one syncbo. Also there are no tools in the middleware to add these settings, the only way to do this is to modify the xml manually.

How can I use the button in one panel to control the other panel's appearing and disappearing?

How can I use the button in one panel to control the other panel's
appearing and disappearing? What I want is when I push the button on
one button . another panel appears to display something and when I
push it again, that the second panel disappears.

You want to use a combination of three features, a button on the panel,
code to notice value changes using either polling in a state machine of
some sort or an event structure, and a VI Server property node to set
the Visible property of the VI being opened and closed.
The button exists on the controlling panel. The code to notice value
changes is probably on the controlling panel's diagram, and this diagram
sets the Visible property node of a VI class property node to FALSE or
TRUE to show or
hide the panel. To get the VI reference to wire to the
property node, you probably want to use the Open VI Reference node with
the VI name.

How to enable /disable a command Button based on a table's selectOne choice

Hi everyone.
I am using JDeveloper 10.1.3.3 and wish to enable / disable a commandButton based on the user's selection of the selectOne radio button.
The idea is that a row of a table may have an associated document so I want to enable or disable the button that downloads it based n the current row selected.
I have followed the advice on problem with table I defined my selectOne component as follows :
<af:tableSelectOne text="#{res['tables.selectionFacet.title']}"
    autoSubmit="true"
    attributeChangeListener="#{backing_browseCVs.onSelectionChange}">The function inside the backing bean looks like this
    public void onSelectionChange(AttributeChangeEvent attributeChangeEvent)
        // access the faces context
        FacesContext fc = FacesContext.getCurrentInstance();
        // get value of the expression #{row.hasCVDocument} that indicates
        // if a document has been added
        ValueBinding vb =
            fc.getApplication().createValueBinding("#{row.hasCVDocument}");
        Boolean hasDoc = (Boolean)vb.getValue(fc);
        // enable the doownload button accordingly
        downloadCVDocBtn.setDisabled(!hasDoc);
    }My problem is that the method never fires. I have placed a breakpoint at the first line but it is never reached.
Any advice will be most welcome.
Thanassis

Hi,
You might need to add 'dataProvider' part in the expression language in your selectionListener:
#{bindings.CVList.currentRow.[b]dataProvider.hasCVDocument}
#{bindings.CVList.currentRow} returns an instance of ViewRowImpl which does not have 'getHasCVDocument()' method, but does have:
Object getCurrentRow()
method, which returns objects from your CVList list, which do have getHasCVDocument() method...
Expression language is resolved through reflection, so when you write:
#{processScope.someClass.someReferencedClass.someAttribute} it is something like:
Get someClass from processScope map, then:
someClass.getSomeReferencedClass().getSomeAttribute()
It's a bit more complex but you get the idea.

Enabling/Disabling a button in Web appl. based on exception in a Query

Hi all,
I am wondering whether we can grey out a button in the web applic. designer based on whether a report has an exception showing.
So now we can enable or disable a button, so at runtime, when the web app runs, and a condition is visible in the analysis item table, then the button (save for example) should be disabled, otherwise if there are no exceptions then it should be enabled.
I am thinking Javascript, but not sure how to read the exceptions in a web apps query?
Thanks for any help forwarded.

Hi Sumit,
just add one more attribute of type wdy_boolean, and bind this attribute to readonly property of button by coding.
then as per your cell value set the attribute value, below is the some sample code.

        lt_mara TYPE ig_componentcontroller=>elements_mara,
        wa_mara TYPE ig_componentcontroller=>element_mara.

                                 WHERE meins = 'GM' OR meins = 'CCM'.

Enable / Disable a button Based on a value

Hi all,
How can i enable or Disable a Button Based on some input Text value.
Here is the ADF Code fragment:
*<af:switcher id="customActionButtons"*
*facetName="#{actionAvailable.isCustomActionButtons}">*
*<f:facet name="true">*
*<af:panelGroupLayout layout="horizontal" id="pgl10">*
*<af:commandToolbarButton actionListener="#{invokeActionBean.setOperation}"*
*text="#{wf:getResourceValue('APPROVE', 'bindings.customActions')}"*
*disabled="#{!bindings.APPROVE.enabled}"*
*action="#{invokeActionBean.invokeOperation}"*
*partialSubmit="false"*
*visible="#{wf:isCustomActionAvailable('APPROVE', 'bindings.customActions')}"*
*id="ctb2">*
*<f:attribute name="DC_OPERATION_BINDING"*
*value="bindings.APPROVE"/>*
*</af:commandToolbarButton>*
*<af:inputText value="#{bindings.input.inputValue}"*
*label="#{bindings.input.hints.label}"*
*required="#{bindings.input.hints.mandatory}"*
*columns="#{bindings.input.hints.displayWidth}"*
*maximumLength="#{bindings.input.hints.precision}"*
*shortDesc="#{bindings.input.hints.tooltip}"*
*id="it1">*
*<f:validator binding="#{bindings.input.validator}"/>*
*</af:inputText>*
I have highlighted the Button and Input text in Bold.
Any suggestions,
Thanks,
karthik

you need to set the autosubmit property for the text field to true. and set the partial trigger for the the button to that input text id.
and set the rendered property for the button based on the input text value.
same idea is exist in this link:
