[Xerte] What is the correct way to set thepropertiesofscriptduplicated text Icons?

[Johnathan Kemp]

When I have finished it I will send you a copy.
 
I am trying to learn the button accordion.
The idea of the project is to enable me to select a Key e.g. C major, D
major etc. and have the keyboard display highlight only the keys on the
keyboard that belong to that key.
The purpose is to aid in building up a spacial / pictorial sense of
where the keys are whilst picking out a tune by looking at the sheet
music and glancing across at the keyboard map.
 
I think it will be helpful in the learning process, I will know better
when I try it out.
 
If it seems a useful learning tool then extra bits would be to allow the
user to select the size of keyboard and to select which key system they
wish to use e.g. C system, B system.
 
Kind regards
 
Johnathan

Any chance you want to show what you're doing? It sounds interesting...

Maybe:

 

- create an array, with objects in it, one for each key:

 

myArray = [{note:'C', x:25, y100}, ...etc]

 

Then duplicate the icons. Use the array to position them: so refernce
the array from the icon properties:

 

so for x:

 

myArray[icon.index()].x

 

etc.

 

Use a similar expression in the text icon to show the text:

 

{myArray[icon.index()].note}

Hello Xerte Team,

I am trying to develop a Xerte project that will display the keyboard of
a button accordion, with the user able to select from a range of
keyboard sizes.

I have tried two different approaches to achieving this, both on the
same basic idea of having a page with a text Icon that is then
duplicated as many times as there are keys on the keyboard, by script at
run time.

Which ever method I use I have not been able to correctly change the
newly generated textIcon properties.
I am sure it must be something simple I am missing.

I need to be able to change the x and y properties to position the key,
To change its text to display the Note of the key,
to change its colour and its alpha property and to draw a circular
border around it.

I think once I can get the correct expression to change one property I
will be able to resolve everything else, because then the correct syntax
for accessing the icon, to get at its properties and methods will have
been identified.

Can you give me an example of how I should be setting the properties, so
that I can stop banging my head against the wall ? :-)

Method 1. By using duplicateIcon
Page
        textIcon (id = protoKey)
        script


I use the following in the script
=============================================================
allKeys = new Array();
allKeys[0]= protoKey.duplicateIcon(0);
allKeys[1]= protoKey.duplicateIcon(0);
// this is a test my intention will be to use a loop to create the
elements of the array
// that will repeat once for each key on the keyboard
// new icons are created but I cannot set the properties.

allKeys[0].clip()._y=100;
// this is shifting the whole project display, leaving a blank area 100
deep at the top of the project
============================================================

Method 2. By using duplicate
Page
        script
        textIcon (no ID)

I then use in the script
===============================================
// create the number of text icons - each text icon will eventually be a
key on the keyboard display
if (icon.attributes.built != "true"){

  icon.nextSibling.duplicate(5);
  icon.attributes.built = "true";
// the figure 5 is for testing to prove the concept, eventually it will
be set by the user in an earlier
// interaction when they select the keyboard size

// create an array of the text icons
allKeys = new Array();
allKeys = icon.parentNode.findChildNodes("type","text");

// I then want to be able to set properties for allKeys[0], allKeys[1]
etc.
================================================


Kind regards

Johnathan
