RE: [Dynapi-Help] Setting the scale for one object based on another.

[Brian H. <bg...@ke...>]

 Thanks for the information, and after reading a lot of code... I came up
with the answer... I guess I did not explain myself clearly, but here it the
code. Ugly but works... Does, anyone know of a cleaner way of doing the
below?

// Sets the Smaller' ScaleViewerContainer' =100 (Scalled Down) layer, based
on 
// the  'ViewWin' = 300 larger (Original Size) Layer.
// Each time the Larger 'ViewLyr' a child of 'ViewWin' layer is resized,
moved, draged, etc.. I call this funtion.
// and change to change the size of 'ScaleViewer' a child of
ScaleViewerContainer.
// function setViewWindow does the same thing but for setting the ViewLry
v.setScaleViewer = function(lyrid){
	if(this.ViewLyr[lyrid]){
		this.rh =
this.ViewLyr[lyrid].getHeight()/this.ScaleViewerContainer.getHeight();
//ratio Height
		this.rw =
this.ViewLyr[lyrid].getWidth()/this.ScaleViewerContainer.getWidth(); //ratio
Width
		
		this.sw =this.ViewWin.getWidth()/this.rw;
		this.sh =this.ViewWin.getHeight()/this.rh;

		this.rx = (this.ViewLyr[lyrid].getX()*-1)/this.rw;
		this.ry = (this.ViewLyr[lyrid].getY()*-1)/this.rh;


		this.ScaleViewer.setSize(this.sw,this.sh);
		this.ScaleViewer.setLocation(this.rx,this.ry);
		//
		//this.ScaleViewer.setHTML("<font color=white>"+this.rx+" :
"+this.ry+"<br>"+this.rh+" : "+this.rw+"</font>");
		//alert(this.nw);
	}
};
v.setViewWindow = function(lyrid){
	if(this.ViewLyr[lyrid]){
		this.rh =
this.ViewWin.getHeight()/this.ScaleViewer.getHeight(); //ratio Height
		this.rw =
this.ViewWin.getWidth()/this.ScaleViewer.getWidth(); //ratio Width
		
		this.sw =this.ScaleViewerContainer.getWidth()*this.rw;
		this.sh =this.ScaleViewerContainer.getHeight()*this.rh;

		this.rx = this.ScaleViewer.getX()*this.rw;
		this.ry = this.ScaleViewer.getY()*this.rh;

		this.ViewLyr[lyrid].setSize(this.sw,this.sh);
		this.ViewLyr[lyrid].setLocation(this.rx*-1,this.ry*-1);

	}
};

You might want to try using the onresize and onlocationchange events to make
the adjustments.

I believe a LayoutManager is in the making but it you can create one then
that would be cool.
