LrDialogs.showModalProgressDialog(): does not hide on completion

Jepp, works.

I actually tried LrTasks.yield() before in the same manner, but that was when I did not use the second function context so it had no obvious effect...

Thanks!

Argh. Looks like there is a task that has to run after the function context unwinds.

In the code snippet above, insert a call to LrTasks.sleep(0) immediately in front of your LrDialogs.presentModalDialog call.

In my understanding, the API docs say it should disappear: "This dialog remains visible (and blocks the operation of all other Lightroom UI elements) until the progress scope is marked completed or canceled."

Wrapping within another function context -- that's what I did, but the progress dialog still remains.

...

LrTasks.startAsyncTask( function()

  LrFunctionContext.callWithContext('a function', function(aContext)



    LrFunctionContext.callWithContext('another function', function(anotherContext)

      local progressScope = LrDialogs.showModalProgressDialog({

        title = 'Progress',

        caption = 'Doing some work',

        cannotCancel = true,

        functionContext = anotherContext,

      })



      progressScope:setPortionComplete(0.0, 1.0)

      LrTasks.execute(someCmd)

      progressScope:done()

    end)



    LrDialogs.presentModalDialog(dialogArgs)



  end)

end)

Oh OK. I misunderstood you yesterday. I thought the problem was that the progress dialog outlived the function context. Now I see that your concern is that the progress dialog remains visible after the :done() call. It's probably reasonable to expect that, but it isn't how it's implemented now.

A workaround: You could add another function context to wrap the area where you want the progress dialog to be visible.

I am sorry, I forgot to mention the platforms. I tested it on Windows 7 Build 7000 + LR 2.3RC as well as on Windows XP + LR 2.1.

This time I ran the code isolated, same result, this is the complete code I used:

Info.lua

return {

 

 LrSdkVersion = 2.0,

 LrSdkMinimumVersion = 2.0, -- minimum SDK version required by this plug-in



 LrPluginName = 'ModalProgressDialogSample',

 LrToolkitIdentifier = 'ns.ModalProgressDialogSample',



 LrExportMenuItems = {

  title = "ModalProgressDialogSample Test",

  file = "MenuItem.lua",

 },

 LrLibraryMenuItems = {

  title = "ModalProgressDialogSample Test",

  file = "MenuItem.lua",

 },

}

MenuItem.lua

local LrTasks = import 'LrTasks'

local LrFunctionContext = import 'LrFunctionContext'

local LrDialogs = import 'LrDialogs'

local LrView = import 'LrView'



local someCmd = '"ping -n 3 localhost"' -- force delay (Windows)



local dialogArgs = {

  title = 'Another dialog',

  resizable = true,

  contents = LrView.osFactory():static_text { title = 'Progress dialog still visible?' },

  actionVerb = 'sure',

  cancelVerb = 'gone', 

}



LrTasks.startAsyncTask( function()

  LrFunctionContext.callWithContext('a function', function(aContext)



    local progressScope = LrDialogs.showModalProgressDialog({

      title = 'Progress',

      caption = 'Doing some work',

      cannotCancel = true,

      functionContext = aContext,

    })



    progressScope:setPortionComplete(0.0, 1.0)

    LrTasks.execute(someCmd)

    progressScope:done()



    LrDialogs.presentModalDialog(dialogArgs)



  end)

end)

Hmm ... when I run this code snippet on both Mac and Windows, the dialog does go away as expected.
