    Based on a request I received, the WixProgressBar comes handy for showing long processes. You just run the .SetProgressBar(elementID, config) and it will show a progressbar anytime you want to show it.


    • Item As Map
      return the item
    • SetType (sType As Object) As WixProgressBar
      set type - top,bottom,icon
    • SetTypeTop (typeTop As Object) As WixProgressBar 'ignore
      draw a bar above the view/application
    • SetTypeBottom (typeBottom As Object) As WixProgressBar 'ignore
      draws a bar below a view/application
    • SetTypeIcon (typeIcon As Object) As WixProgressBar 'ignore
      draw an icon in the middle of a view/application
    • SetIcon (icon As Object) As WixProgressBar
      icon name to display from font awesome
    • SetDelay (delay As Int) As WixProgressBar
      life time in milliseconds of the progress bar, after which it is hidden (if hide parameter is enabled)
    • SetHide (hide As Boolean) As WixProgressBar
      specifies whether a progress bar/icon should be hidden after its life time
    • SetPosition (position As Double) As WixProgressBar
      an optional parameter, true only for the progress bar. Specifies the position of a progress mark on a bar. Varies from 0 to 1.
    Usage of the class.

    Dim pbx As WixProgressBar
    "propbag", pbx)
    We want to show a progress bar for 500 milliseconds and hide it and it should be placed at the center of the "progbar"

    The other variations are top and bottom, for top

    Dim pbx As WixProgressBar
    "propbag", pbx)

    You can guess what bottom does..

    You can show the progress bar indefinately by leaving the delay and hide options out. Doing that will mean you will unset it off yourself. You can unset it by executing

    .UnsetProgressBar("propbar") in this example.

    Internally these functions are...

    'set a progress bar to an element
    Sub SetProgressBar(eid As String, pbdef As WixProgressBar)
        eid = eid.tolowercase
    Dim pb As BANanoObject = webix.GetField("ProgressBar")
    Dim itm As BANanoObject = Dollar.Selector(eid)
    "extend"Array(itm, pb))'
        itm.RunMethod("showProgress", pbdef.Item)
    End Sub

    'unset the progress bar
    Sub UnsetProgressBar(eid As String)
        eid = eid.ToLowerCase
    End Sub
