hello thanks for this plugin!
but when your are full screen with nothing else how can you come back to toolbar?
thx again

Can I ask you a question？How do you make a *.html files does not display a dialog box in SketchUp ？just like the ams_WindowSettings.I think it is very cool.So ,if possible ，can you give a simple example？

Anton_S

Ying2014, here is a code snippet which allows you to remove borders from the dialog:


# Create a web dialog
@title = 'MyDialog'
@dialog = UI;;WebDialog.new(@title, false, 'MyDialog', width, height, ix, iy, true)
# Add Callbacks
@dialog.set_on_close(){
  @dialog = nil
  @handle = nil
}
# Set file
@dialog.set_file(html_path)
# Show dialog
RUBY_PLATFORM =~ /mswin|mingw/i ? @dialog.show ; @dialog.show_modal
# Find dialog handle
@handle = AMS;;Sketchup.find_window_by_caption(@title)
# Remove dialog caption and borders
if @handle
  layered = AMS;;System.get_windows_version < 6.0 ? 0 ; 0x00080000
  style_ex = 0x00010000 | layered # WS_EX_CONTROLPARENT | WS_EX_LAYERED
  style = 0x94000000 # WS_POPUP | WS_VISIBLE | WS_CLIPSIBLINGS
  AMS;;Window.lock_update(@handle)
  AMS;;Window.set_long(@handle, -20, style_ex)
  AMS;;Window.set_long(@handle, -16, style)
  AMS;;Window.lock_update(nil)
  AMS;;Window.set_pos(@handle, 0, 0, 0, 0, 0, 0x0267)
end

Basically, what it does is creates a webdialog, finds its handle, and removes its borders. Along with removing borders it adds a layered style, which allows it to be made transparent.

To make the dialog draggable, you'd have to implement a few callbacks in your javascript file that would respond to mouse click and mouse move. Here is a snippet:


function callback(name, data) {
  if (!data) data = "";
  window.location.href = "skp;" + name + "@" + data;
}
$(document).ready( function() {

  var md = false;
  var pos = [0,0];
  var dragged = false;
  
  // Detect Drag.
  $( "#some_id" ).mousedown(function(e) {
    md = true;
    var x = e.clientX;
    var y = e.clientY;
    pos = [x,y];
    callback("drag_start", null);
    dragged = false;
    return false;
  });
  $( document ).mousemove(function(e) {
    if (!md) return;
    var x = e.clientX;
    var y = e.clientY;
    var dx = x-pos[0];
    var dy = y-pos[1];
    if ((dx == 0) && (dy == 0)) return;
    dragged = true;
    callback("drag", "["+dx+","+dy+"]");
	return false;
  });
  $( document ).mouseup(function(e) {
    if (md) {
      md = false;
      callback("drag_end", null);
	  return false;
    }
  });
});

In the code above, "#some_id" has to be changed to any id of an element in your HTML. It can also be changed to document to respond to drag anywhere in HTML.

Then have these callbacks implemented in SketchUp:


@offset = [0,0]
@dialog.add_action_callback('drag_start'){ |dlg, params|
  c = AMS;;Cursor.get_pos
  d = AMS;;Window.get_origin(@handle)
  @offset = [c.x - d.x, c.y - d.y]
}
@dialog.add_action_callback('drag'){ |dlg, params|
  c = AMS;;Cursor.get_pos
  x,y = [c.x - @offset.x, c.y - @offset.y]
  AMS;;Window.set_origin(@handle, x, y, false)
}
@dialog.add_action_callback('drag_end'){ |dlg, params|
  @offset = [0,0]
}

To change dialog opacity, use this function:
AMS::Window.set_layered_attributes(@handle, 0, opacity, 2)

To make the dialog clip to screen and snap to viewport, you'd have to add more ruby functionality and modify dialog position in the 'drag' callback. I would advice looking into ams_WindowSettings/main.rb for source.

Description

AMS Library is a collection of tools and functions used to interact with SketchUp window and its sub-windows using Microsoft Windows API. It's capable to switch SketchUp full screen, show/hide toolbar containers, status bar, scenes bar, and more elements of the window. It's also capable to observe and make decisions to various events of the window procedure. In many ways, this library is written to achieve things that cannot be done with standard SketchUp API.

This library includes Ruby FFI and and Win32 API extensions as part of the utility. Both of these gems are recompiled under my own name-space for compatibility with other extensions. I do not take ownership of such gems, nor I claim any credit for them. I just happen to rely on them so much that it was essential to include them in the library.

Requirements

Microsoft Windows XP, Vista, 7, or 8

SketchUp 6 or later

It is a great lib!

one question:

when i use swo_on_maximize ,like this
class MySketchupObserver
def swo_on_maximize
r=AMS::C.get_viewport_rect()
p r
end
end
AMS::Sketchup.add_observer($o=MySketchupObserver.new)

I found get_viewport_rect returns the value of viewport before maximized.

So, can you provide a method like swo_on_maximized, will be called when maximize complete?

thank you for the great lib!

wikii

Anton_S

That's a good idea. I will add swo_on_post_[event] methods in the upcoming version.

Anton_S

Hi Wikii. I added the post-events.
You should try out this example in Ruby console:

class MySUWindowObserver
  def swo_on_maximize
    puts 'swo_on_maximize'
    p AMS;;Sketchup.get_viewport_rect()
  end

  def swo_on_post_maximize
    puts 'swo_on_post_maximize'
    p AMS;;Sketchup.get_viewport_rect()
  end

end # class MySUWindowObserver

my_obs = MySUWindowObserver.new
AMS;;Sketchup.add_observer(my_obs)

Hi Anton_S ！

It works well in my pc.
It is really cool!

Thank you for your working.

But I have one question more：

When I use win+left or win+right to fill Sketchup to half the size of the screen, which observer call catch this operation?

Thank you!

wikii

Anton_S

Currently, no observer catches such operation, but if you want to track window moving and resizing, you can always use swo_on_enter_size_move, swo_on_size_move, swo_on_exit_size_move, or/and swo_on_viewport_size. Check out available observers here: http://www.rubydoc.info/github/AntonSynytsia/AMS-Library/master/AMS/SketchupObserver

Hello, when I updated to 3.0.0 WindowsSettings didn't work any more, I had to delete both AMS Lib and WindowSettings and reinstall them to make it work again. Just thought I'd mention it in case anyone else has this problem.

Pherim

I am not entirely sure, because I have not used SketchUp very much recently, but this plugin could be causing crashes for me, since I only noticed this happening after I installed the new version and it seems to have stopped since I deactivated it (and the Windows Settings plugin with it).

Anton_S

Thanks for your feedback Pherim. It would be nice to know more details about the crash, so that I could fix it in case it came from that plugin:

What Windows version and SU version were you using?
Were you using AMS Library 3.0.1 and AMS Window Settings 4.2.0 - the latest versions of these plugins?
When did the crash occur? Did it occur right away or after some time of using SU?
What were you doing at the time the crash occurred? Like, what tool were you using or what command were you accessing?
What is the list of other plugins you have installed?

Your response would be greatly appreciated,
Anton

Pherim

Hello,

I'm using Windows 7 Professional 64bit and the newest version of Sketchup Make 2015 64bit.
Yes, both plugins were up to date. I am completely sure about this as I had to uninstall both and then reinstall them via the plugin store to make it work at all... just updating both plugins somehow did not work, as I wrote in the post before. I also updated it to 3.0.1 after I wrote this post.
I am not entirely sure, and right now I am unable to reproduce the crash... it's just that I noticed suddenly that when I changed the tool the cursor would not change as it was supposed to, and also the old tool would still be highlighted in the toolbar. And then, as soon as I right-clicked on a component (well, at least it was a component or group at least some of the times it happened), Sketchup crashed instantly. Well, at the moment it doesn't seem to happen even with your plugins active, but I'll be on guard about it.
Quite a lot I'm afraid... Though so far, they all worked fine together, and so did the old versions of your plugins.

At the moment everything seems to be fine. If this changes, I'll get in touch again.

Anton_S

Thank you for your response, Pherim. I, too, came across cursor changing issues, but didn't consider it was related to my library. For AMS Library 3.x.y, the main difference between prior versions, is that I modified it to be Unicode rather than Ascii. That said, I probably implemented something improperly. I will look into that issue.

Anton_S

Hello Pherim. I tried to reproduce the crash or inconsistent cursor changing behavior with AMS Library 3.0.1, but, similarly to your trial, I couldn't. It is very likely that such bug persisted in version 3.0.0, but not in the current version, 3.0.1. But to be sure, I'll keep an eye on the library.

AMS::Window.send_message can sent something to a sketchup window, but,how to get message in sketchup by ruby?

thank you.

Anton_S

Are you asking for a windows function, like [GetMessage](https://msdn.microsoft.com/en-us/library/windows/desktop/ms644936(v) or [PeekMessage](https://msdn.microsoft.com/en-us/library/windows/desktop/ms644943(v)?

Current version of AMS Library, doesn't have these functions implemented.
However, you can implement a Windows function manually, using Win32::API that is shipped with AMS::Library. Here is an example:


module MyDesiredNamespace

  GetMessageA = AMS;;Win32;;API.new('GetMessageA', 'PLLL', 'I', 'User32')
  GetMessageW = AMS;;Win32;;API.new('GetMessageW', 'PLLL', 'I', 'User32')

  class << self

    # Get windows message ANSI.
    # @note GetMessage waits until the message is received. This means this
    #   function will freeze the computer until the message is triggered.
    # @param [Fixnum] filter_min Value of the lowest message value to be retrieved.
    # @param [Fixnum] filter_max Value of the highest message value to be retrieved.
    # @param [Fixnum] handle A handle to the window whose messages are to be retrieved.
    # @return [Array] Message inforamtion;
    #   [handle, message, wParam, lParam, time, x, y]
    # @see https://msdn.microsoft.com/en-us/library/windows/desktop/ms644936(v=vs.85).aspx
    def get_messageA(filter_min, filter_max, handle = AMS;;Sketchup.get_main_window)
      buffer = "\0" * (4 * 7)
      # See https://github.com/djberg96/win32-api for Win32;;API usage
      res = GetMessageA.call(buffer, handle, filter_min, filter_max)
      return buffer.unpack('lLlllll')
    end

    # Get windows message Unicode.
    # @note GetMessage waits until the message is received. This means this
    #   function will freeze the computer until the message is triggered.
    # @param [Fixnum] filter_min Value of the lowest message value to be retrieved.
    # @param [Fixnum] filter_max Value of the highest message value to be retrieved.
    # @param [Fixnum] handle A handle to the window whose messages are to be retrieved.
    # @return [Array] Message inforamtion;
    #   [handle, message, wParam, lParam, time, x, y]
    # @see https://msdn.microsoft.com/en-us/library/windows/desktop/ms644936(v=vs.85).aspx
    def get_messageW(filter_min, filter_max, handle = AMS;;Sketchup.get_main_window)
      buffer = "\0" * (8 * 4) * (4 * 3)
      # See https://github.com/djberg96/win32-api for Win32;;API usage
      res = GetMessageW.call(buffer, handle, filter_min, filter_max)
      return buffer.unpack('qLqqqll')
    end

  end # class << self
end # module MyDesiredNamespace

# In the following case, the function will return when left or right mouse
# buttons are click caption or non-client area of any window.
res = MyDesiredNamespace.get_messageW(0x0A1, 0x0A6, 0)

However, if you're aiming to monitor Sketchup action commands, which come when different tools are activated, then you'll probably want to use AMS::SketchupObserver with swp_on_command(id):


class MyObserver

  def swp_on_command(id)
    # Process command here
    p id
    # Return 1 to block this command; 0 to pass this command
    0
  end

end

my_observer = MyObserver.new
AMS;;Sketchup.add_observer(my_observer)

Hi Anton_S

Thank you for you reply！

If I want send a message from Sketchup window A to Sketchup window B, I can use AMS::Window.send_message.

But ,how can Sketchup window B get to know there is a message come from window A?

I think ， Window B must have an observer to get message when message come.

I want to konw , can window B respond message sent from A immediately?

Thank you for you great lib!

Hmm, communication between windows? That's interesting! I will look into that.
