Mac UI.messagebox - hud and timeout

mac UI, you had used GUI in your template and I just change it to MUI, for now at least.

What happens if the user resizes the Sketchup application window, after the module is loaded ?
It's dynamic, it updates the prefs file with changes then modifies shell script before running. The dat file is a list of 8 items so it's quick and has very little overhead, compared to the normal applescript methods.
I still need to read/write some back in ruby, but I'm trying to limit that to a minimum.

Well I think the ultimate goal, is to have a cross-platform UI module:

example:

module SKX;;GUI

  MAC =( RUBY_PLATFORM =~ /(darwin)/ ? true ; false )
  WIN =( not MAC )

  if MAC
    def self.timed_splash( *args )
      # code calling Applescript, etc.
    end
  else # it's Windows
    def self.timed_splash( *args )
      # code using Win32API calls
    end
  end # if MAC

end # module

In practice actually, there would be a loader that determines the platform, and it would require one of two files:
skx_gui_mac.rb or skx_gui_win.rb

This is how Wx::Windows is setup when it loads.

Anyhow, within any author's nested plugin module or class, they can create a pointer to the actual GUI module, using anyname they wish (since it's local to their namespace.)
Ex:

module Driven
  module Util
    class ExportWidget
      MUI = SKX;;GUI
      MUI.timed_splash("John's Export Widget",10)
      # more code ...
    end # class
  end
end

The pointer can be a local constant, or a local var, a class var, doesn't matter. All references in Ruby just point at objects. A class or module name is just a constant that points at the instance objects of class Class and class Module, respectively.

An update for those interested,

After following up on Dan's old suggestion to TIG, about using Thread.new for mac shell running, I have a non-freezing applescript/shell test that runs from a button in SU. The problem I was having with the shell/SU blocking has gone... yeh.

At the moment I've made a proof of principle/demo, to show that the 'threading' works and speed is useable.

It dynamically resizes SU to a number of random sizes, based on host Monitor size.

For each, in turn, it dynamically creates a 'centered' random sized message-box based on the new windows size. [min-max preset as %]

The messages are also random, as are the font, shadow and background colors.

It takes SU full screen at the end.

What I need next is confirmation of it working the same on other macs, before adding all the other bits that already work separately, but not yet combined. There's no reason to think it won't as it uses all mac, SU and Ruby 1.8.5 standard functions. but....

I'll try and make a small enough screen-cast to post this demo here for none mac watchers.

here's a zipped dmg for any willing mac owners... please.
download for testing...

For some reason i can't upload to YouTube, so I put a movie up here http://gallery.me.com/johnboundy#100086

the movies quite compact at 1.2MB, but a small, crap animated giff version comes in at 12MB... I don't follow that.
it has 6 or so random window being created...

Dan Rathbun

Bummer.. it a QT movie. Cannot install anything else right now. (Getting the old "System part of the Resgistry has reached it's limit..." messagesboxes.)

Perhaps someone else can convert it WMV or AVI or something that YouTube likes ?

driven

Can you not view it online?

I can make and upload to youTube normally, just not at the moment... I'll try tomorrow. john

driven

Dan, could you try to stick this on YouTube?

emu zipped PC friendly AVI.... I think

Dan Rathbun

It would not run on my Windows Media Player (mesagebox saying wrong format or you don't have the correct codec.)

TIG

Runs OK for me on VLC or WMPlayer... but then I probably have every codec known to man...

I have most, but selecting what to use for windows eludes me.

OK the second works fine for me. Had to adjust the play speed to slow.

What do you call this kind of "popup" ??

It's not really a splash window (that usually has a graphic background.)
Not a "messagebox", as that term is taken (although I would have called them "queryboxes", myself.)

It is similar to the icon bubble notification boxes on XP, both system and app (though they popup in the lower right corner of the screen.) Calendar "reminder" apps and AV/Firewalls are the biggest consumers of these "bubble" notice windows. Anyway, these kind of windows, are timed and close or shrink away after an interval with no user interaction.

Anyone have an idea if there is a standard generic name for this type of window ?

The original is referred to as a DisplayMessage and uses com.apple.ScreenMessage to run, with a full screen base size, on targeted computers in a mac network.

I believe 'Growl' uses something similar for it's 'placable' Screen Notifications.

Which is a bit like Chrome has for webkit- Event Target: Notification

in Cocoa...
maybe - (void) somethingHappened:(NSNotification*):notification {...}

I guess it's more of a bodged Target[ed:Application_DisplayMessage], but, as it has the ability to return a user response?

I can't find a Ruby equivalent, although MacRuby may have something along these lines, being app centric.

Aerilius

I've seen it often called as "OSD" or on-screen-display (similar to HUD, head-up-display) or OSD notification.

Likely any Ruby equiv. would be a class in the GTK or Wx (or similar toolkit modules.)

Name: OK.. it looks like "Display" and "Notify/Notification" may be the buzz words, for this. "On-Screen" seems a bit 'obvious' (although, I suppose, one can have an Audio notification, as well.)

"Display" is too vague.

I'd prefer: GUI.notify_box( message, timeout, [opts_hash] )
with the (dismissal) return value true || false

If the timeout arg != 0 and the box times out and closes, false is returned.
If the user dismisses the box before it times out, true is returned.

If the timeout arg == 0, then the user MUST manually dismiss the box, and true is ALWAYS returned, in this case.

Of course the timeout arg can have a default, say 5 secs ?

The hash_opts (3rd arg,) can be specified without braces, in the method call, but Ruby should collect them (automatically,) into a internal hash argument.

Yep... deleting the poll, did not fix the phpBB bug (looks like.) It seemed to be OK for a few days, until someone else posted again. I was never aware that Aerilius posted. It did not show in the right column where the most recent post & poster goes. (It always showed the OP's name.)

I've been distracted by almost having a WebDialog do the same things as my macMessage video shows. [but it's an 'almost' standard webdialog].

Certainly this approach would be easier to implement (on both platforms.)

Jim, ThomThom and I, have all played around with changing a WebDialog's window styles, just after calling it's show method.
On Win32 we can change it's border style to a ToolWindow, or even turn off all the borders entirely. I suppose we could also make the background semi-transparent.

We do these via Win32API system calls.

I'm not sure if the WebBrowser control can see the parent window object as implemented in the WebDialog class, via HTML,CSS or Js. Seems like I recall us trying, and getting a Js error. (We discussed this awhile back, on the subject of making WebDialog that acted just like floating toolbars, and switching window focus to the SU main app window, when a WebDialog control was clicked.)
Anyway ... I suspect we cannot change the WebDialog window's borders (and so forth,) FROM the Javascript running IN the WebDialog. (I'd love to be proven wrong on this.)

Dan Rathbun

Playing around with this idea a bit... I realized we cannot have the method return a value from the notifypanel because the method creating it would have to wait.. and that would cause SU blocking. (possibly ghost-window "whiteout".)

That's what was happening here, the block bit, until I put it in it's own thread.
