HTMLDialog vs WebDialog?

Garry K

Thanks guys - I haven't had time to look into this yet. But what I see looks encouraging.

gotcha, you mean bug SU-35701.

Let us know if any of the suggestions work.

I have some issues with Mac users and my webdialogs. Unfortunately, I don't have a Mac computer at my disposal so I can't directly test and debug the issues but it appears to be some behavior with the blocking not working correctly in MacOS.

Does anyone have any suggestions on a work around for this problem.

I've been tempted to switch to HTMLDialog from WebDialog but I have too many people using the plugins who have older versions of SU.

I also don't see any distinct advantage to switching unless it will fix my MacOS problem.

Here is my code for my webdialog for the timber truss feature that I recently added. I think the issues with Mac users may have to do with the dialog not being "modal" even though I am using the show_modal method:

# Create the WebDialog instance
if @Licensemode == "trial"
  dlg1 = UI;;WebDialog.new("Timber Truss Geometry - Medeek Truss Plugin - (trial version)", true, "SelectionInfoPrefKey", 1210, 860, 500, 250, true)
else
  dlg1 = UI;;WebDialog.new("Timber Truss Geometry - Medeek Truss Plugin", true, "SelectionInfoPrefKey", 1210, 860, 500, 250, true)
end

dlg1.add_action_callback("PUSHTOHTML_SETTINGS") {|dialog, params|
   		
  js_command = 'pushdata( "' + @Trusstype.to_s + '|' ....  .... '|' + @Panel.to_s + '" );'
  # puts js_command
  dialog.execute_script(js_command)	
}

dlg1.add_action_callback("GET_SETTINGS") {|dialog, params|
   		
  params = params.to_s
  # puts params
  paramlist = []
  paramlist = params.split("|")

  @Trusstype = paramlist[0]

  @Span = paramlist[1]
  if @Span == ""
    @Span = @TrussSpan_ft
  else
    @Span = @Span.to_f
  end

....				

  @Panel = paramlist[20]
  if @Panel == ""
    @Panel = @Span * 12.0 * 0.25
  else
    @Panel = @Panel.to_f
  end
}

dlg1.add_action_callback("CLOSE_DIALOG") {|dialog, params|
  dialog.close
}

# Find and show our html file
	
dlg1.set_file File.dirname(__FILE__) + "/html/web_dialog_timber_truss.html"
dlg1.show_modal()

can you add a link to the version showing issues...

without the html and params it's impossible to guess the issue...

I doubt it has anything to do with modality of the window...

The html code is rather large due to the insane amount of javascript that is used to generate the SVG preview so rather than post it on the board it can be viewed here:

(design.medeek.com)

Just take a look at the source code of this page.

The version of the plugin having the issues is 1.9.8, download here:

are they seeing errors like this?

the `onLButtonDown' doesn't finalise before the dialog shows, and then creates and new dialog when you click again...

I will check with the user who reported the error and see what I come back with. Thank-you for helping me look into this.

The error codes posted above.

Dan Rathbun

@medeek said:

The error codes posted above.

... are occurring (according to your error messages,) in " medeek_roof_truss.rbs", line 5726, in callback method onLButtonDown.

In the first you are calling a *() method upon an object that is referencing the global singleton nil object. Since the NilClass does not have an "asterisk" method, a NoMethodError is raised.

The second method is caused by your code expecting a Float object, but getting a String object instead.

The answer is simple. Whenever an object reference could reference disparate types (classes) of obejcts, use a combination of type validation and Ruby rescue clauses with the onLButtonDown callback method.

Okay 95% of that just went over my head, but I'll try and decipher into terms I can understand.

But why would this error only be raised for SketchUp running on MacOS and not Windows?

Dan Rathbun

Basically I'm trying to prompt you to learn how to read Ruby error and backtrace messages.
“filename:lineNo: inmethod”‘ or “filename:lineNo.”`

Data validation - Wikipedia

(en.wikipedia.org)

An example in Ruby of testing if an object reference is pointing at an object of a certain class:
if obj.is_a?(NilClass)
... or ...
if obj.is_a?(Float)

An example in Ruby of validating that an object reference call responds to a certain method call:
if obj.respond_to?(:methname)
... and testing for the "asterisk" method specifically:
if obj.respond_to?(:*)

@medeek said:

I don't know (offhand) as I avoid Macs myself. (But OSX and MS Windows use different sets of keycodes.)

Actually, looking at the backtraces (in your original error listing) the errors are kicked off by a LButtonDown keypress, but are occurring in the `` create_timber_geometry()`' method, lines 1064 and 1355.
