hi*Layout expanding string/button fields in the gui

Hi Paul,

This is just because the form you are looking at is using `hiCreateButtonBoxField' and not `hiCreateButton'

Here is an example that should provide you with everything you need regarding form layouts:

(hiDisplayForm
  (hiCreateLayoutForm 'custom_form "Custom Form"
    (hiCreateFormLayout 'main_layout ?items (list
        (hiCreateButtonBoxField
          ?name   'buttonField1
          ?prompt ""
          ?choices  '("Browse"     "Display"    )
          ?callback '("CCSbrowsed" "CCSdisplay" )
          )
        (hiCreateHorizontalBoxLayout 'buttons_layout ?items (list
            '(spacer_item 20)
            (list
              (hiCreateButton ?name 'button0 ?buttonText "Stretch 1" ?callback (lambda (@rest _args) nil))
              'stretch 1)
            '(stretch_item 1)
            (list
              (hiCreateButton ?name 'button1 ?buttonText "Stretch 2" ?callback (lambda (@rest _args) nil))
              'stretch 2)
            (hiCreateButton ?name 'button2 ?buttonText "No Stretch" ?callback (lambda (@rest _args) nil))
            ));buttons_layout
        ));main_layout
    ))

Note that stretch, stretch_item and spacer_item only works inside `hiCreateHorizontalBoxLayout' and `hiCreateVerticalBoxLayout'

If you use `hiCreateFormLayout' your fields will not expand vertically although the field prompts will align nicely

Hope this helps,

Aurélien

Thanks for the info
It has helped a lot on understanding the hi*Layout forms

Is there a way to either have the fields larger or stretchable in the vertical or y direction?

Paul

Fields will "stretch" vertically too (provided that you are allowing it in the appropriate layout). However, for most fields it doesn't make sense for them to get larger vertical (unless the fonts are increased in size); there are exceptions such as multi-line text fields, list boxes and so on - these clearly make sense to grow vertically.

Its good to know it s possible ( a hint on how to do it would be nice )

Reviewing the functions hi*Layout, it seems the functions to create the form would be below ( rough skeleton of rht format I will use )

hiCreateLayoutForm('ExGridLayout "Grid"
      hiCreateVerticalBoxLayout('vbox
          ?items list(
                hiCreateGridLayout('grid
                    ?items list(
                          list(hiCreateLabel(
                                  ?name 'enableLabel
                                  ?labelText "Enable")
                                   'row 0 'col 0)

Recent versions of the tools (plus on support.cadence.com) have got better examples (I created a bunch of them) but of course they don't cover everything. Here's an example of a multi-line text field which stretches in both dimensions and the label stays where it is:

hiCreateLayoutForm('ForumStretchLayout "Grid"
  hiCreateGridLayout('grid
    ?items list(
      list(
        hiCreateLabel(
          ?name 'bigTextLabel
          ?labelText "<b>Big Text</b>"
        )
        'row 0 'col 0 'vert_align 'top
      )
      list(
        hiCreateMLTextField(
          ?name 'bigText
        )
        'row 0 'col 1
      )
      list('col_stretch 0 0)
      list('col_stretch 1 1)
      list('row_stretch 0 1)
    )
  ?frame "My frame"
  )
)

hiDisplayForm(ForumStretchLayout)
