jsx3.app.Model.getDescendantsOfType
method getDescendantsOfType(strType, bShallow)
Finds all descendants of the given type.
Parameters:
strType {String | Function | jsx3.lang.Class} – the fully-qualified class name, class constructor function, or jsx3.Class instance.
bShallow {boolean} – if true, only search direct children, not all descendants.
Returns:
{Array<jsx3.app.Model>} – an array of matching descendants
for example:
/**
* Bind change events of the specified control and its all children to the specified callback function.
* exceptedControlNames don't bind change event
*/
Eric.bindChangeEvents = function(rootNode, callback, exceptedControlNames) {
if (exceptedControlNames == undefined) {
exceptedControlNames = [];
}
// bind change events for TextBox
var children = rootNode.getDescendantsOfType("jsx3.gui.TextBox");
for (var i = 0; i < children.length; i++) {
if (exceptedControlNames.indexOf(children[i].getName()) == -1) {
children[i].subscribe(jsx3.gui.Interactive.JSXCHANGE, callback);
}
}
}
