Cycler

[Xarxus]

OK, now what I would like to do is to have a button_stringcycler whose value is saved on the DB. There must always be a value on a field of the DB. I declared it wirhout the sourceles tag.

<button_stringcycler name="mycycler">
    <anchored width="60">
        <left parent="mylabel" anchor="right" offset="10"/>
        <top parent="mylabel" />
    </anchored>
</button_stringcycler>

In the LUA code, I initialized the values and labels in the same way:

myValues="one|two|three|four|five"

Now I can initialize mycycler passing labels, values, empty value and default value.

mycycler.initialize(myValues, myValues);
or
mycycler.initialize(myValues, myValues, nil);
or
mycycler.initialize(myValues, myValues, "");
or
mycycler.initialize(myValues, myValues, nil, "one");
or
mycycler.initialize(myValues, myValues, "", "one");
or
mycycler.initialize(myValues, myValues, "one");

The is no way to:

1. have the value initialized with the db value ("one") - I've already tried to use

   mycycler.setStringValue("one")

2. hide the empty value

A can remove "one" from the intial values/labels, but I still have no good result.

I get an initial good result using

mycycler.initialize(myValues, myValues, "one", "one");

But if I close and reopen the window, mycycler is empty.

Ok, here is my solution. In this way I always have a field (and a value) on DB and I've no empty string shown.

Template

<template name="mybutton_stringcycler">
   <button_stringcycler>
      <script file="common/scripts/mybutton_stringcycler.lua" />
      <sourceless/>
   </button_stringcycler>
</template>

mybutton_stringcycler.lua

local _nodeRecord;

function onInit()
    _nodeRecord = window.getDatabaseNode();

    if super and super.onInit() then
        super.onInit();
    end
end

function onValueChanged()
    DB.setValue(_nodeRecord, self.getName(), "string", self.getValue());
end

window class

<mybutton_stringcycler name="mycycler">
    <anchored width="60">
        <left parent="mylabel" anchor="right" offset="10"/>
        <top parent="mylabel" />
    </anchored>
</mybutton_stringcycler>

window code

local _nodeRecord;       

function onInit()
    _nodeRecord = window.getDatabaseNode();

    myValues="two|three|four|five";

    mycycler.initialize(myValues, myValues, "one");
    mycycler.setStringValue(DB.getValue(_nodeRecord, "mycycler", "one");
end
