Detecting/selecting a temporary Drawing

[penpendrum]

I want to make a sketchup tool.. I wanted it to select a temporary drawing like it will change color when I select or hover my mouse on it ..
can anyone give me a head start on how to do it

I have done a lot of google search but i just cant seem to pin point what kind of term fits it

what i need is :
1.) to detect and change the color of the temporary drawing square in the "def draw" everytime i hover and select it
2.) to detect and change the color of the temporary corner of the square in the "def draw " everytime i hover and select it

please examine my code below

class MyTool

def initialize
  
end


def activate

    @mouse_ip = Sketchup::InputPoint.new
    @picked_first_ip = Sketchup::InputPoint.new

 
    
end

def draw(view)
  @mouse_ip.draw(view) if @mouse_ip.display?
  
  
  # Draw a square.

points = [
Geom::Point3d.new(0, 0, 0),
Geom::Point3d.new(9, 0, 0),
Geom::Point3d.new(9, 9, 0),
Geom::Point3d.new(0, 9, 0)
]

Fill

view.drawing_color = Sketchup::Color.new(255, 128, 128)
view.draw(GL_QUADS, points)

Outline

view.line_stipple = '' # Solid line
view.drawing_color = Sketchup::Color.new(64, 0, 0)
view.draw(GL_LINE_LOOP, points)

end

def onLButtonDown(flags,x,y,view)
  puts "yout tool has clicked"
   
end

def onLButtonUp(flags,x,y,view)
  puts "yout tool has clicked"
  puts  
    
end

def onMouseMove(flags, x, y, view)

    if picked_first_point?
      
      @mouse_ip.pick(view, x, y, @picked_first_ip)
      puts "point A"
    else
     
      
    @mouse_ip.pick(view, x, y)
      
    end
   
    if @mouse_ip.valid?
    view.tooltip = @mouse_ip.tooltip 
    
    
    end
    
    starting_point = Geom::Point3d.new(9, 0, 0)
    ip2 = Sketchup::InputPoint.new(starting_point)
   view.inputPoint(x,y,ip2)
    
    view.invalidate
end

def picked_first_point?
    @picked_first_ip.valid?
  end

def getBoundingBox(corner)
  model= Sketchup.active_model
  selection = model.selection
  
  return selection[0].bounds.corner(corner)
end

def resume(view)
  view.refresh
end

end

my_tool = MyTool.new

Sketchup.active_model.select_tool(my_tool)

No one will attempt to even read you code until it is properly formatted within [ code ] ... [ /code ] tags.

There is a button on the post edit toolbar to insert these tag sets, or highlight a bunch of text and click the button to wrap the text in these tags.
