Canvas initiation with constraints

[procop95]

Dears.

this issue is related to issue #7 opened by me previously.
problem is: in cases when canvas is instantiated by calling
canvas = new draw2d.Canvas("canvas", 4000, 4000) - without directly mentioning css {width: 4000px; height: 4000px} in container;
will cause figures not be able to be moved outside initial area (viewport) of the container.

this behaviour is caused by line 121 of Canvas.js:

// installed to all added figures to avoid that a figure can be placed outside the canvas area
// during a drag&drop operation
this.regionDragDropConstraint = new draw2d.policy.figure.RegionEditPolicy(0, 0, this.getWidth(), this.getHeight())

where this.getWidth() and this.getHeight() will return initial viewport dimensions.

change this to:

   this.regionDragDropConstraint = new draw2d.policy.figure.RegionEditPolicy(0, 0, this.initialWidth, this.initialWidth)

will do proper job, if you agree.

thanks
Alex

You have an error in your solution:
I think it should be:
this.regionDragDropConstraint = new draw2d.policy.figure.RegionEditPolicy(0, 0, this.initialWidth, this.initialHeight)

This fix (last arg corrected to this.initialHeight) solved my issue. This line was also causing scrolling to malfunction.

fixed with version 1.0.23. the width/height in the constructor is propagated as CSS attribute to the named DIV
