Sketchup View origin

Anton_S

I want to get the origin of view, relative to screen coordinates

Dan Rathbun

Viewport:

classname : "AfxFrameOrView80u"
ControlType : "ControlType.Pane"
LocalizedControlType: "pane"
Name: ""
AutomationId: "59648"

Really interesting, what do i do with that?

You were asking about making system calls.

Use the info to find the view window. Once you have it's handle, you can request it's position on the screen.

see this thread for examples:

[Code] Win32 Moving/Showing/Hiding Toolbars and Dialogs

driven

This script, by Matthew Scarpino, [written initially for PC's] gives the true design window on my mac.

Is this what you want, or does SU-PC draw toolbars in view?

"Automating Sketchup" by Mat is a great book...

view = Sketchup.active_model.active_view

# Determine the size of the design window
h = view.vpheight.to_s;
w = view.vpwidth.to_s

# Display the window dimensions
puts "Window dimensions; " + w + ", " + h

# Display the locations of the four corners
puts "Upper left; " + view.corner(0)[0].to_s + ", " + 
   view.corner(0)[1].to_s
puts "Upper right; " + view.corner(1)[0].to_s + ", " + 
   view.corner(1)[1].to_s
puts "Bottom left; " + view.corner(2)[0].to_s + ", " + 
   view.corner(2)[1].to_s
puts "Bottom right; " + view.corner(3)[0].to_s + ", " + 
   view.corner(3)[1].to_s
   
# Find the location of the window's center
center = view.center

# Display the coordinates of the window's center
puts "Center; " + center[0].to_s + ", " + center[1].to_s 

# Screen coordinates
origin = view.screen_coords [0,0,0]
puts "Origin; " + origin[0].to_f.to_s + ", " + origin[1].to_f.to_s

# Find out how many units a five-pixel line should take
size = view.pixels_to_model 50, [0, 0, 0]
puts "Size of a 50-pixel line at the origin; " + size.to_s

On Windows view.corner always return's the corners relative to view origin.
So, view.corner(0) always return's [0,0], view.corner(1)[0] gives the view.width, view.corner(2)[1] return's the height. View.center returns [width/2, height/2]. From these, there is no way of knowing the Sketchup view origin relative to actual, screen coords.

What I wan't is the Windows API or some other Function(s) that would give me the hwnd to Sketchup viewport. The Windows API Function FindWindow only works at finding the handles to the windows. It can't find the handle to a panel, button, icon or other stuff, but only to a window. Since viewport is a panel, FindWindow function wouldn't be able to get its handle.

If I got the handle to viewport, I could then use GetWindowRect(hwnd, rect) method to get 1st and last corners of viewport in actual screen coordinates.

Sketchup View is not a Window. I tried getting its handle by using function FindWindow.call(className, 0) but got 0. Then tried testing on toolbar dialogs. When toolbar was a child window (or not embeded into SU), I could get its handle, but when it was embedded into SU, FindWindow function returned 0. So, the FindWindow function doesn't works at finding handles to the panels, or 'ControllType.Pane'

Rightnow, I get the hwnd to viewport like that:

MyTool
  def onMouseEnter(view)
    p = 0.chr*8
    GetCursorPos.call(p)
    cp = p.unpack('ll')
    @viewport_hwnd = GetWindowFromPoint.call(cp[0], cp[1])
    rect = 0.chr*16
    GetWindowRect.call(@viewport_hwnd, rect)
    @viewport_rect = rect.unpack("l*")
  end
end

Sketchup.active_model.select_tool(MyTool.new)

Not a good way. I would only be able to get vieport handle, once mouse enters the view.

Sketchup View is not a Window.

EVERYTHING you see on the screen, in Microsoft Windows, IS a window. A button, an edit box, a static text label, a checkbox, ... ALL of them are a window, but their style does not have a resizable frame or a caption bar, like a application window or a dialog (which are also a window.)

FindWindow does NOT find embedded child windows, only toplevel windows.

You have to get the handle for the Sketchup Application window (the parent window,) then use that in
view_window_handle = FindWindowEx.call(parent_window_handle,0,"AfxFrameOrView80u",0)

Then use GetWindowRect using the view_window_handle.

Thank you really much!!!, That should help!!!!
