Cannot use a block with a custom type in a block group in the toolbox. Can someone help?

[David Kadouch]

Hi

I have a problem with using custom type blocks in the toolbox. Would appreciate some help here.

1) I defined a new block that return a custom type 'font family'. This type is then used for the last argument of the block  set_text_attributes (as seen below)

Blockly.Blocks['font_family'] = {
  init: function() {
    this.appendDummyInput().appendField(new Blockly.FieldDropdown(
      [["helvetica", "helvetica"], ["courier", "courier"], ["comic", "comic"]]), "font");
    this.setOutput(true, "font family");
  }
};

Blockly.Blocks['set_text_attributes'] = {
  init: function() {
    this.appendDummyInput().appendField("set text settings");
    this.appendValueInput("color").setCheck("String").setAlign(Blockly.ALIGN_RIGHT).appendField("text color");
    this.appendValueInput("bgcolor").setCheck("String").setAlign(Blockly.ALIGN_RIGHT).appendField("bgcolor");
    this.appendValueInput("size").setCheck("Number").setAlign(Blockly.ALIGN_RIGHT).appendField("size");


this.appendValueInput("font").setCheck("font family").setAlign(Blockly.ALIGN_RIGHT).appendField("font");
    this.setPreviousStatement(true);
    this.setNextStatement(true);
  }
};

2) I would like to have a 'set_text_attributes' block in the toolbox with a default input font block. So in my XML definition of the toolbox I added the block below, but I get an exception 'Uncaught ReferenceError: prototypeName is not defined'. 

Alas I didn't find a similar example. 

<block type="set_text_attributes">
  ......
       <value name="font">
          <block type="font family">
            <field name="font">helvetica</field>
          </block>
        </value>
</block>

thanks

David

Hi David,

I think you need an underscore in

<block type="font family">

so it reads

<block type="font_family">

Cheers
