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

[Brian Hayes]

Hello everyone, I have been at this for about (well all night) and I seem to be missing something... What am I trying?

 

Well, When one layer grows, I need another layer to shring accourdingly.. Plus, if I move one layer I need to other layer to move accourdingly.. Everything I have tried seems to be close, but not there... Not to mention looking at the code in scrollbar.js, but being a little week in math?? Well, lets say its not my cup of tee..

 

Please help...

 

example:

 

ViewWin is my larger Window and ScaleViewerContainer is my smaller window..

The two objects that need to interact are ViewLyr[lyrid] where lyrid is the layer in focus (larger) and ScaleViewer the smaller one.

-Both of the obove are contained in there parent layers ViewWin -> ViewLyr[lyrid] and ScaleViewerContainer -> ScaleViewer..

 

  this.rh = this.ViewWin.getHeight()/this.ScaleViewer.getHeight(); //ratio
  this.rw = this.ViewWin.getWidth()/this.ScaleViewer.getWidth();
  this.sw =(this.ViewLyr[lyrid].getWidth() - (this.ScaleViewer.getWidth()/this.rw))/this.rw;
  this.sh =(this.ViewLyr[lyrid].getHeight() - (this.ScaleViewer.getHeight()/this.rh))/this.rh;

 

  this.nh =  this.ScaleViewerContainer.getHeight() - (this.sh-this.ScaleViewer.getHeight());
  this.nw =  this.ScaleViewerContainer.getWidth() - (this.sw-this.ScaleViewer.getWidth());
  //this.rh = this.ViewWin.h/this.ScaleViewerContainer.h; //ratio
  //this.rw = this.ViewWin.w/this.ScaleViewerContainer.w;
  this.rx = (this.ViewLyr[lyrid].getX()*-1)/this.rw;
  this.ry = (this.ViewLyr[lyrid].getY()*-1)/this.rh;

 

  this.ScaleViewer.setSize(this.nw,this.nh);
  this.ScaleViewer.setLocation((this.rx/this.rw),(this.ry/this.rh));

 

Thanks, Brian Hayes
