ddsSyncWithForm Question

acook

When I run ddsSyncWithForm, it does not block my code from proceeding. For example

procedure( myButtonCB()

 ddsSyncWithForm(myForm 'browse 'libName 'cellName 'viewName)

myfunction() 

) 

 

I would like myfunction to run after the user has selected a cellview, instead it exectes immediatly.

As suggested in another post, I do not want to just trigger every time myForm->viewName is changed since I cannot know that the user has chosen the cell they want yet.

Is there a way to create a dialog that where the user selects a LCV and then returns that selection and allows the code to continue to execute or do I need to write my own implementation?

Thank you,

Aaron

    Aaron,

    I don't believe there's a blocking version of this. You'd probably have to build your own.

    I went down the buld your own path (which was a good choice actually) but now I've got a new issue.

     For some reason the callback on my listbox is taking forever (1-4 seconds) so when I select a library there is lag until the cells get shown. I did some debugging and the lag does not seem to be due to my callback.

    Here is what my listbox looks like:

       l_lib = hiCreateListBoxField(

          ?name 'l_lib

          ?prompt ""

          ?choices libList

          ?value list()

          ?defValue list()

          ?valueByPosition nil

          ?callback "CGlibSelectCBlib"

          ?changeCB ""

          ?multipleSelect nil

          ?doubleClickCB ""

          ?CBOnReselect ""

          ?keepHistory nil

          ?enabled t

          ?invisible nil

          ?help ""

       ) 

     

    Here is it's callback:

    procedure( CGlibSelectCBlib()

     

       current_lib = car(cglibselect_form->l_lib->value)

     

       cellList = ddGetObj(current_lib)~>cells~>name

       cglibselect_form->l_cell->choices = cellList

          cglibselect_form->storedCells = cellList

       CGlibSelectCBcell()

     

    ) 

     

    It takes several seconds to get to the first line in that callback. Is this normal for the listbox or something up with my code library? 

  • Andrew Beckett

    I don't think it's taking several seconds. What is happening is that the callback doesn't get called until the focus moves out of the field - that's normal with all field types. I tried this - if I move my cursor out of the form, then it gets triggered.

    I think you probably want to use ?changeCB rather than ?callback. If you do that, it calls the callback as soon as you've clicked.

    Regards,

    Andrew.

    Ahh! Sorry, I just didn't read the doc well enough.

    t_changeCB

    SKILL command executed when the value (selected items) of the

    list box has changed. Programmatic SKILL changes can also

    trigger this callback, for example:

    form->listbox->value->list( “newValue”)
