Enabling Push Buttons

Hi Gurus,
I have a column of push buttons in my table control, each push button for each line item.
According to my requirement, I disabled the push button column initially, it will only get enable depending
upon each line item's condition.
Like, 1st row, if rad2 = 'x' , then the push button for that line should get enabled.
2nd row, if rad2 = 'X', then the push button for that line should get enabled.
3rd row, if rad2 NE 'X', then the push button for that line should be disabled.
I tried a lot , but its not happening. May be because I disabled the column based on the screen group.
Can anyone please help me on this ?
Thanks
Chandan

Hi,
First assign some function keys for Radio buttons..
and assign the Logic for enabling and disabling screen logic in the PBO..
Refer:
Take the group1 for the screen fields that you have taken on screen as ABC and then follow code to disable fields, in PBO:-
IF <condition>. "as per your condition
IF screen-group1 = 'ABC'.
    LOOP AT SCREEN.
      screen-invisible = 0. "to disable screen fields
    ENDLOOP.
    MODIFY SCREEN.
ENDIF.
ENDIF.
Now say if you want to enable fields on some condition then you may use:-
IF <condition>. "as per your condition
IF screen-group1 = 'ABC'.
    LOOP AT SCREEN.
      screen-invisible = 1. "to enable Push Button
    ENDLOOP.
    MODIFY SCREEN.
ENDIF.
ENDIF.

How to Enable a Push Button In The Form That Is Always Greyed Out?

Greetings All,
I am trying to enable an existing "Return" Push Button(PB) which is always greyed out whenever the form is called in either an update or review mode. After some research, I found that this PB's functional property is "Enabled" (i.e. the enabled value = 'Yes'), and it is coded programatically set 'Off' in 30 places and 'On' in 2 places in the form that I inherit from my predecessor by using the following code:
SET_ITEM_ON_OR_OFF('BLK_UPDATE.PB_RETURN', <XXXXX>);
Where <XXXXX> could be either TRUE or FALSE. I've been spending a lot of time in trying to enable this "Return" PB (without modifying the existing programming code) by adding the 'SET_ITEM_ON_OR_OFF' built-in command to set the PB on in WHEN-BUTTON-PRESSED TRIGGER for the PB_RETURN and WHEN-NEW-FORM-INSTANCE Trigger, but all tries in vain. Could you please help me with the following question?
What is the easiest way to enable a PB that is set programmatically?
Is there something else I should know to enable a PB, in addition to what I have already mentioned above?
Thanks in advance,
Jinlan

Thanks all for your information and help. I included the following code, as suggested by Manu, in WHEN-MOUSE-DOWN TRIGGER for the PB_RETURN and WHEN-NEW-FORM-INSTANCE TRIGGER:
SET_ITEM_PROPERTY ('BLK_UPDATE.PB_RETURN_WORK_REQ', ENABLED, PROPERTY_TRUE);
and I made sure there was no " SET_ITEM_ON_OR_OFF('BLK_UPDATE.PB_RETURN_WORK_REQ', FALSE);" statements after the above code, but, the "Return" PB is still in grey; in other words, it is still not accessible when my form is called.
Perhaps, I need to place the above SET_ITEM_PROPERTY code in a different trigger other than the triggers mentioned above, uh? Any thoughts on this?
Manu,
You are absolutely right that the "SET_ITEM_ON_OR_OFF" is an ih-house written procedure which is defined/stored in the Attached Libraries. (I should have checked before making the "built-in" assumption. Thanks for catching and clarifying this.) Please help me with the following questions:
How do I view the procedure in the Attached Libraries???
Thanks in advance,
Jinlan

I need to add the same existing functionality in a differenct view for which i am not able to find the details in the Structurte of Component IUICMDC. Please help us.
Thanks and Regards to all
P.Raj

Hi,
You need to know wich view you want to add the new push button.
In trx. BSP_WD_CMPWB select the view and enhance it. Go to the view layout and check if you see something like this
        <uhtmlb:toolbar id              = "Toolbar"
                        buttons         = "<%= controller->get_buttons( ) %>"
                        maxButtonNumber = "3" />
If yes, and I think you will find enhance the method get_BUTTONS OF _impl class
Add the code
CLEAR ls_button.
ls_button-id       = 'New Button'.
ls_button-text     = 'New text'.
ls_button-on_click = 'NEWMETH'.
ls_button-enabled = 'X'
APPEND ls_button TO rt_buttons.
Create a method with name you used in on_click property.

Push Button in Every record in ALV grid output

Dear Experts,
I need to print a push button in first column of every record in ALV grid output. How ?
No OOPS concepts please.
Thanks,
Siva.

For this requirement, you have to copy the standard PF status of the ALV output. Do as below :-
1) Go to SE41
2) Enter the program name as SAPLKKBL
3) In the field status enter STANDARD_FULLSCREEN
4) Click on STATUS button on the application toolbar.
5) Enter the name of your Program & a new status name.
6) Click on COPY.
This way the standard status will be copied to the custom status & call the same status in your program using SET PF STATUS statement. Then double click on the custom status name & you will be navigated to SE41, there you can add you new button on the application tool bar & assign a function code, which you can program by enabling the export parameter I_CALLBACK_USER_COMMAND of the Function module REUSE_ALV_GRID_DISPLAY.
Just a sample code snippet for your reference :-
FORM USER_COMMAND USING L_UCOMM LIKE SY-UCOMM
LS_SELFIELD TYPE SLIS_SELFIELD.
CASE L_UCOMM.
WHEN 'your function code goes here'.
Do further processing.
This way you will have the standard PF status alongwith your button as well.

Push button signal to parallel port to trigger a process

I just need to connect a push button to the parallel port to set it as a trigger signal for a process.
When push button is pressed, labview executes a process.
Kindly help me how to do this, the wiring please

Success is Everything !!
Solved!
Go to Solution.

Data Lines to be used as inputsSome parallel ports can be configured to use the data lines as inputs. It depends a great deal on the way the manufacturer designed the parallel port. With some models the data lines can be read the same way we read the control lines, by driving them to high logic so they will take on the value of an external signal. However, most parallel ports require that you set the direction bit for input. This is bit 5 in the Control register (base+2). If the port is capable of it, setting the direction bit high has the effect of making the lines tri-state so it can be driven externally. Sometimes it is also necessary to toggle bit 6 high or low. However, it should be noted that some manufacturers actually lock these bits so that software cannot change them. An example is shown below in Figure 7.
To test whether your data lines can be used for input, try the following:
Set bit 5 of the control register high (at base address+2).
With nothing connected to the port, write a couple of values to the data port, and read each back after you write it.
If the reads DON'T match the writes, your port is probably bidirectional. Setting C5 disabled the data outputs and you're reading the open inputs of the data-port buffer. If the reads DO match the writes, your port isn't bidirectional. The data outputs are still enabled, you're reading back what you wrote, and you won't be able to read external signals. If it is possible to use your data lines for input, then you just need to set control register bit 5 high and read from the value of the data lines at the base address.

Issue with Icons display in PUSH BUTTONS in forms 11g

Hello,
This is regarding an issue with the icons background for the push buttons in the forms 11g. When we enable the icons for the buttons (.gif) they are visible on the
top left corner of the buttons and not in the centre. In one of the forums it was written like this is a common problem in Forms 11g. Is there any way by which we can
centralize this icons on the Forms buttons. Also I have heard that image editing tools can be used to centralize the icons. I tried with one of the tools but it seems
like it is not working.
Can somebody suggest a workaround for this?
Thanks in Advance
Ram

I will assume you are attempting to use the images included in the Forms applet jar. These images are purposely structured so that the subject is off-centered. You should not see that same behavior if you use your own images or edit the ones built-in to Forms. However, keep in mind that the images packaged in the Forms applet jar are intended to be used in a menu toolbar and not custom buttons.

How to add left push button column in REUSE_ALV_GRID

Hi,
I need to add the push button on the left most part of the grid which will enable the user to select multiple lines and do further processing. I'm currently using REUSE_ALV_GRID.
I've tried to search but I only saw suggestions for ALV using OO.
Please help. Thanks.

Hi,
If you ar eusing OO ABAP
declare : ls_layo TYPE lvc_s_layo,
You have to set...   ls_layo-sel_mode = 'A'.
If you are using 'REUSE_ALV_GRID_DISPLAY'..
go for the following ..

Push Buttons, Radio Buttons, Folder Tabs

Could someone please let me in on the secret to selecting
background colors for push-buttons, radio-buttons and folder
tabs. I've tried the obvious properties with no luck.
I am developing on a Windows NT 4.0 platform using Developer
6.0. I will be releasing my app to the web soon and could
really use some help.
Ideally, I would like to be able to select any color ( i.e. to
match the background color of the canvas ), but so far the only
choices seem to be black, white or a couple of other non-
desirable colors ( bright red, green, yellow, yuck! ). Is a
custom color palette the ticket?
I realize that many button properties are controlled by Windows.
If this is the case, are there any work-arounds? When I
distribute the application, will I be able to offer my customers
the ability to configure Windows to correctly define the button
colors?
I am sure that others have these same questions. I have not
been able to find any answers. Any help is greatly appreciated.

Hi,
1. Disabling Push button.
    In PBO loop at sccreen and check the field name is equal to push button name
    set screen-input = 0.
    modify screen.
    endloop.
2.assign a function code to radio button in screen element it will trigger the PAI.
In PAI during loop at table control check the field value is equal to 'X'.then not down the roqw number and in PBO enable the button based on the row number by looping at screen.
3Assign the fcode to push button.Once the user presses the button in PAI check the focde and see for which line it is pressed based on it call the pop up screen using FM or dialog box.

Function keys for Push buttons

Hi All,
I have one query in module-pool program,I need to assign Function keys to Push buttons in my programe,like for create(F7),dispaly(F6) and also I need to overwrite few standard function keys,
any one please guide me.
Thanks n regds,
Sree.

Hi,
you want in more detail.....ok
(1)u've created a screen -
> added push buttons etc. -
> given name to screen elements i.e pushbuttons etc.and also declared them in program
(2) create its GUI status ,say STATUS_100---->here you have to assign Function codes ->like if in standard toolbar you want BACK,EXIT,CANC or whatever you want,for ex. for BACK u'll find its icon -> double click on it>give the Func code say F3,now u also wnt to enable Func Key F3 for this--> go to UTILITIES (menu bar)-> F Key consistency-> here u will find all the Func keys-> so to F3 give the same func code as u gave to BACK icon button.
similar approach u can use for pussbuttons:
double click on push button> in screen painter attributes-> give the Func code to it ,say for CREATE button u give Func code NEW->come back to GUI status->similarly go to UTILITIES (menu bar)-> F Key consistency-> here u will find all the Func keys---> so to F7 give the same func code (NEW) as u gave to CREATE push button.
(3) In PBO of this screen create a module to set its PF status:
In screen flow logic:
PROCESS BEFORE OUTPUT.
* To set pf-status and title
MODULE status_0100.
In Program:
MODULE status_0100 OUTPUT.
SET PF-STATUS 'STATUS_100'.
SET TITLEBAR 'TITLE_100'.
ENDMODULE.
Hope this much detail is quite clear!!!
