    Set Focus Reply

     Hello,

    I have a StringField, that looks like this:

    hiCreateStringField(
                        ?name 'Test
                        ?prompt "Folder of Test File:.............................................."
                        ?value mvalue
                        ?invisible list(nil)
                        ?callback "checkDirEx( )"
                     )

     where my callback-routine looks like that:

     procedure(checkDirEx()
      prog(()
        
          if(!isDir(MyForm->Test->value) then
            if(hiDisplayAppDBox(
                  ?name 'questMsgDBox
                  ?dialogStyle 'modal     ; wait for user-interaction before continuing
                   ?dboxBanner "Directory not found"
                  ?dboxText sprintf(nil "Warning: the entered path does not exist.\nWould you like to change it?" )
                  ?dialogType hicQuestionDialog
                  ?buttonLayout 'YesNo)==t then    
                Test->focus=t

               )
        )
              
     
      )
    )

    Is there a way to set to Focus to a field?

    Have you tried hiSetCurrentField?

    If I understand your question right you whant to set the
    focus to one of the dialog box buttons 'Yes' or 'No'?

    There is an argument for the
    'hiDisplayAppDBox' function
    called '?defaultButton'.
    Have a look at the
    'Cadence User Interface SKILL Functions Reference',
    Chapter 4, Dialog Boxes.
    'Example, if the s_buttonLayout argument is set to 'YesNo, and the x_defaultButton is set to 2,
    the No button will be the default button.

    Re: Set Focus Reply

    Thank you for your replies. The button-thing from Bernd is another thing I was looking for.  

    Actually, what I want, is that, if the user enters a path, that is detected as wrong or not existing - there is the DialogBox, that informs the user when he exits the path-Stringfield by clicking into or onto another element on the form.

    Then, when he clicks on YES, the focus should be back in the path-stringfield instead of the element he clicked on.

    The hiSetCurrentField(); doesn't work somehow - is there another thing that can do the trick or is there anything to beware of by using this function?

    Re: Set Focus Reply
    I would implement it in this way:
     - The string field calls the 'checkDirEx' callback.
     - The 'checkDirEx' sets the field to highlight an error if the directory does not
       exist and displays the 'Yes/No' dialog, I come to this more specific below.
       The question here is:
        "Warning: The entered path does not exist. Would you like to change it?"
       It is pretty obvious that one would to change it if it does not exist, isn't it?
       What should happen if the user selects 'No', you didn't tell that, should the
       directory be created then. This has an influence on you callback structure.
       So I decided in my example to just fire a warning and did no questionnaire.

     - And hence I  realized that the 
       'hiSetCurrentField' seems to have not effect, neither in the
       'hiDisplayAppDBox' callback nor in the string field callback 'checkDirEx'.
       The field focus always seems to be be on the field where you cursor was
       positioned before the dialog box pops up.

    procedure( checkDirEx( r_formDataStruc )

    when( !hiIsInFieldCancel( )
    if( isDir( r_formDataStruc->r_validStringField->value ) then
    hiHighlightField(
    r_formDataStruc
    'r_validStringField
    'background
    )
    nil
    else
    hiHighlightField(
    r_formDataStruc
    'r_validStringField
    'error
    )
    hiDisplayAppDBox(
    ?name 'warningDialog
    ?dboxBanner "Directory not found"
    ?dboxText strcat(
    "Warning: The entered path \""
    r_formDataStruc->r_validStringField->value
    "\" does not exist.\n"
    )
    ?dialogType hicWarningDialog
    ?buttonLayout 'Close
    ?callback "hiSetCurrentField( hiGetCurrentForm( ) 'r_validStringField )"
    )
    t
    ) ;; close if
    ) ;; close when
    ) ;; close procedure


    procedure( UIcreateMyForm( )
    let( ( r_validStringField r_dummyStringField )

    r_validStringField = hiCreateStringField(
    ?name 'r_validStringField
    ?prompt "Folder of test file: "
    ?value ""
    ?callback "checkDirEx( hiGetCurrentForm( ) )"
    )

    r_dummyStringField = hiCreateStringField(
    ?name 'r_dummyStringField
    ?prompt "Just a dummy field: "
    ?value ""
    )

    hiCreateAppForm(
    ?name '_myForm_
    ?formTitle "Field Focus Test"
    ?initialSize list( 300 80 )
    ?fields list(
    list(
    r_validStringField
    15:5 250:25 120
    )
    list(
    r_dummyStringField
    15:50 250:25 120
    )
    )
    ?attachmentList list(
    ( hicLeftPositionSet|
    hicRightPositionSet
    )
    ( hicLeftPositionSet|
    hicRightPositionSet
    )
    )
    )

    ) ;; close let
    ) ;; close procedure


    procedure( UIfieldFocusTest( )

    unless( boundp( '_myForm_ ) && hiIsFormDisplayed( _myForm_ )
    UIcreateMyForm( )
    )

    hiDisplayForm( _myForm_ )

    ) ;; close procedure

    Re: Set Focus Reply

    Thanks for that solution Bernd.

    I was wondering if the problem is, that if you exit the StringField by clicking into another Field

    -1st: the callback routine is execute, where there is the command for setting the focus into the same Field, where the user just entered the "wrong text"

    -2nd: the system handles the Click of the user afterwards and sets the focus in a diffrent field, where the user had clicked....

     

    Maybe there could be a solution with a timer or something similar, although this seems like breaking a fly on the wheel.
