Declare the variables in your Application class:
qx.Class.define("custom.Application",
{
extend : qx.application.Standalone,
members :
{
/** My global variable */
bGlobal : true
main : function()
{
// access to global variable from within this class using "this"
this.bGlobal = false;
}
}
}
Then you can access that main application class using
qx.core.Init.getApplication() so in some other class, you can read the
global like this:
qx.Class.define("custom.SomeArbitraryClass",
{
extend : qx.core.Object,
construct : function()
{
/** Access the global variable */
if (qx.core.Init.getApplication().bGlobal)
{
alert("The global is TRUE");
}
}
You could also have made that global be a property of the Application class:
qx.Class.define("custom.Application",
{
extend : qx.application.Standalone,
properties :
{
/** My global variable */
global : true
...
in which case you'd reference it from the other class using the property's
getter:
qx.core.Init.getApplicaiton().getGlobal()
Hope that helps.
