How to make the buttons INVISIBLE in the Application toolbar

Hi All,
I have a requirement to create a button in the Application toolbar of the Module Pool Screen. The field should be made Invisible by default. and it should be displayed based on one condition.
Could you please let me know how to make that particular button INVISIBLE. I think we can make it invisible by using EXCLUDING statement. But, How to make the button VISIBLE again when the check is satisfied.
I found from the portal that the FM 'VIEW_SET_PF_STATUS' can be used to make a button INVISIBLE. Could anyone help me out how to pass the parameters to this Function module?
or is there any Function Module available to make the button VISIBLE and INVISIBLE? Please help me on this issues.
Is there any possibility to make the button VISIBLE or INVISIBLE as we do for the screen fields using LOOP AT SCREEN..?
Thank you in advance.
Regards.
Paddu.

Hi,
Try to use below in the PBO module status_0100 OUTPUT.
DATA t_fcode TYPE TABLE OF sy-ucomm.
refresh t_fcode[].
APPEND 'Function code name of the button' TO t_fcode.
Check the condition here for which you want to make field visible.
DELETE FCODE of the button from T_FCODE table
ENDIF.
SET PF-STATUS 'STATUS_0100' EXCLUDING t_fcode.

I want make my button visible or invisible on click of button

Hi All
I want make my button visible or invisible on click of button.

HI Kiran,
Your Question:
onclick button should be visible and on second click it should become invisible.
Answer:
In your View
1.Add Two button using Apply Template--actionButton
So two buttons will get added to the view
2.Create an attribute in View Context say buttonset of type com.sap.ide.webdynpro.uielementdefinitions.Visibility
Bind the visible property of second button to buttonset attribute
This attribute is to set visibility
Also create a booloean attribute bool in the View context
3.In DoInit method
wdContext.currentContextElement().setBool(true);
So that both buttons are visible in View initially
4.In First button event handler onActionButton()
call second button eventhandler onActionButton_0()
public void onActionButton(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionButton(ServerEvent)
       onActionButton_0(wdEvent);
    //@@end
Here onActionButton_0() is like one method which is actually making second button visible or invisible based on boolean value bool=true /bool=false
5. Write the following code in onActionButton_0() to perform the actual action
    if(wdContext.currentContextElement().getBool()==true){
            wdContext.currentContextElement().setButtonset(WDVisibility.NONE);
            wdContext.currentContextElement().setBool(false);
else{
       wdContext.currentContextElement().setButtonset(WDVisibility.VISIBLE);
                  wdContext.currentContextElement().setBool(true);
6.Now build and deploy ans run your application.
It works..
Nice Question..
I was excited trying this...
Hope it helps You

If you use a click event on each button,
event.currentTarget.id.charCodeAt(0)-97 in the click handler
will give you
the button number.
For the keyboard input, try

Button in the lead application

Dear All
I am working on CRM 7.0
I want to add a button in the lead application so I can call a URL from there, a button like save, expert and so on
Can I do it via configuration or I need I kind of BSP enhancement
Regards
Shawky

Hi Mohamed
I have only access to a CRM 5.2 system, but I suppose the solution is the same. As Verena wrote you need enhancement. In the following I assume you want to add the button to BT108H_LEA/LeadOVViewSet (Please let me know if this is not the case). You need to use the on_client_click instead of the normal on_click (On_click can also be used if you want an event to be triggered on the server).
To do this you have to enhance method IF_BSP_WD_TOOLBAR_CALLBACK~GET_BUTTONS of CL_BT108H_L_LEADOVVIEWSET_IMPL. In the following you do not have to use the 2 string, but we did, because we build a dynamic url:
DATA: lv_java       TYPE string
      lv_http       TYPE string
CONCATENATE 'javascript:window.open'
              lv_http
              '","Print","resizable=yes,height=850,width=700,dependent=yes,status=1");'
         INTO lv_java.
CLEAR ls_button.
ls_button-tooltip         = cl_wd_utilities=>get_otr_text_by_alias( 'Package/Text' ).
ls_button-text            = cl_wd_utilities=>get_otr_text_by_alias( 'Package/Text' ).
ls_button-on_client_click = lv_java.
ls_button-enabled         = abap_true.
ls_button-page_id         = me->component_id.
APPEND ls_button TO rt_buttons.
Best regards, Peter

NEW BUTTON ON IPHONE MAIL APPLICATION......SEE UK GUIDED TOUR!!

Hey guys i must be going mad, but while watching the Uk 30mins guided tour on the apple uk website i noticed a new button in the mail application. Can some please confirm this to be true and does anyone know what this button does???????
Thanks.

Indeed. It is in fact the international keyboard support symbol, it allows for easy toggle between various keyboards e.g. US/UK. Its been available ever since 1.1.1 was released, its just not enabled by default on US phones until you're roaming and have Regional Format enabled.
From the looks of it, its enabled by default on UK (and probably Germany/France) phones. It can be enabled by slight modification on a US phones as shown

Making a button visible upon closing a document

Kind of a weird question, but is there a way to make a button visible upon closing a document? Here's my situation. I want users to click a link which will open a PDF. I then want the users to take a quiz based off of the information in the PDF. Is there a way to have the users click the link to open the PDF, then a button to start a quiz becomes visible when the users close the PDF? I have a feeling it's probably not possible, but I figured I'd check. Thanks.

I was actually able to find a bit of a workaround. I created an advanced action to open the PDF and show the button (it was hidden to begin with) once I click the hyperlink. It's not exactly what I wanted to do, but I think it'll suffice until I figure out a way to show the button upon closing the PDF. I'll look into the java scripting, even though I'm not really a coder. Thanks!

Button visible

Hello,
How can i make a button visible if a shared variable is true and not visible if that same varable is false...?? is this possible??

I would like to do the same but the problem is i have to run the vi each time.
If you want to switch visibility with a FP control while the VI is in edit mode, you can make an xcontrol consisting of a button and a switch for its visibility.
Typically, you should design your VI such that it always runs during use. It can be in a wait state when it's not supposed to do anything.

How do you get out of Full Screen mode in Excel? No red or yellow buttons visible.

How do you get out of Full Screen mode in Excel? No red or yellow buttons visible. Using just installed Yosemite iOS 10.10.2

I Don't think Microsoft updated it for those buttons. Look for a blue button with arrows in it on the right side of the menu bar.
Also try Esc key.

Grey-out button dynamically in the application toolbar

Hi,
How can I grey-out button dynamically in the application toolbar?
It's not an ALV grid, where it's easy.
SET PF-STATUS '100' EXCLUDING 'SOMETHING'. hides completely the button.
Thanks,
Peter

Hi,
Sorry forgot to add something to my previous reply...
The complete steps will be as follows :
1. Create Two PF status , One with active Button and Function code and Second with Inactive Function code and Greyed button (This can be acheive by using Push Button assignment as specified in the thread)
2. Dynamically change the PF status to Second one when you want to deactivate the specified Function from the application tool bar.

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.
