Draw2D touch version 5.1.1 supports AngularJS

blogEntryTopper

Version 5.1.1 provides a boilerplate example for the famous AngularJS lib.

This isn't designed to be completely general purpose, but it will be a good basis if you need a diagramming
solution and you are willing to work with AngularJS.

What is in:
  • two way data binding
  • FileOpen dialog made with AngluarUI
  • drag&drop of elements from an DIV into the canvas
  • property pane of selected figure

Draw2D touch version 5.1.0 released

The main focus of this release is the support for 2-way data binding.

The idea behind 2-way databinding is managing model-view updates in two directions. First, views are updated when a model changes, which is the default case for 1-way databinding. Additionally, views can directly update models, which is a second update “direction”, hence the name “2-way databinding”.

Version 5.0.0 notes and API changes

In the planned version 5.0.0 I want to take the major step of the attribute and event handling of shapes.

Attributes
The new hero in draw2d is the .attr() method that isn't so chatty like the „setBackgroundColor“ or all the other attribute methods with regards to how often attributes were handled. It is more like the famous jQuery interface. I did this in a new release because I thing this is a major step.

Example of draw2d < 5.0.0

     
    // you can use only the "text" attribute in the constructor.
    //
    textFigure = new draw2d.shape.basic.Text("The quick brown fox jumps over the lazy dog");

    // all other attributes must be set by calling the related setter method
    //
    textFigure.setFontSize("20");
    textFigure.setBackgroundColor("#f0f0f0");
    textFigure.setFontColor("#fF00f0");

    canvas.addFigure(textFigure,150,300);


New draw2d API

    // it is now possible to add all required attributes of the shape in the constructor
    //
    textFigure = new draw2d.shape.basic.Text({
          text:"The quick brown fox jumps over the lazy dog", 
          fontSize:20, 
          bgColor:"#f0f0f0", 
          fontColor:"#ff00f0", 
          x:150, 
          y:300});
    
    canvas.addFigure(textFigure);



Additional it is possible to call the attribute method after shape creation

    // it is now possible to addrequired attributes of the shape in the constructor
    //
    textFigure = new draw2d.shape.basic.Text({x:150, y:300});

    // or by the attar method 
    //
    textFigure.attr({
          text:"The quick brown fox jumps over the lazy dog", 
          fontSize:20, 
          bgColor:"#f0f0f0", 
          fontColor:"#ff00f0"});
    
    canvas.addFigure(textFigure);


Please note that the constructor of the shape has changed and calls like new draw2d.shape.basic.Rectangle(300,150) didn’t work anymore! You must call new draw2d.shape.basic.Rectangle({width:300, height:150}). All getter/setter method are still there - but the construct has changed dramatic in this release. Reading shapes from JSON is working fine as well.


Events

This part is still in draft but the direction is clear

Old API (still working)

	  canvas.getCommandStack().addEventListener(function(e){
	      if(e.isPostChangeEvent()){
	          //...more  inspection code here about the executed command---
	      }
	  });


New API

	// register a listener if a shape has move by the user or API call
	//
	figure.on(„move", function(figure){ console.log(„figure moved)});

	// register some listener to the canvas
	// 
	canvas.on(„move“, function(figure){ console.log(„figure „moved);});
	canvas.on(„delete“, function(figure){ console.log(„figure“ deleted)});
	canvas.on(„add“, function(figure){ console.log(„figure“ added)});

+ new example "io_json_multi_document" shows how to load two or more JSON documents into the canvas without clear it before.

+ fixing bug. Call of Line.setGlow(true) ends with invisible line.
+ set ResizeHandles opacity to 0.2 during drag&drop operation to show the border of the shape or line of connection instead of the ResizeHandle. Better for precision alignment.
+ new method Figure.setKeepAspectRation and Figure.getKeepAspectRatio to guarantee, that the figure width/height will not be distorted.
+ undo of Line move operation didn't update resize handles of the line. fixed.
+ add Cut&Paste Operation to the "Shape Designer". This is the first step for a global cut&past in Draw2D. Use Ctrl+C and Ctrl+V
