Re: Re : Re: [openmeetings-user] Precision about variables

[seba....@gmail.com]

its necessary to calculate the boundingbox of the line-object.

If you draw something on the whiteboard the object is relative drawn to the ORIGIN of the whiteboard.

In order to select the object later on I need to know the *virtual box* the boundingbox of the object.

Example:
Initial ULine (Origin): x1=400,y1=400, x2:500,y2:500

=> Bounding Box: x:400,y:400,width:100,height:100
ULine-Object: x1:0,y1:0, x2:100, y2:100

minx/miny is necessary to calc the shift of the object to its actual position.

Ok, its at the beginning of the method endUline, you have :

"Get Bounds of that object"
 var minx = this.width+2;
 var miny = this.height+2;

and after :
" this.currentlayer = new lz.drawViewNew(this,{
                name:tempName,x:minx-1-(this.currentulinelineWidth,
                y:miny-1-(this.currentulinelineWidth),
                width:(width+this.currentlinelineWidth),
                height:(width+this.currentlinelineWidth),
                opacity:this.currentulineOpacity}); "

I don't know if theses variables are responsible of the shifting of the Uline or maybe the update of variables x1,y1,x2,y2.

This is my question.

Any idea about that ?

Thanks

Ok I understand better why you have implemented this like that.

I tried to compare the 2 codes between drawUline and drawline and they are very similar.

I wondered if it is possible or not to have the same behavior of the object line which it doesn't move after the drawing ?

Maybe it will affect the update of bounding box..

Thanks
