Python runtime: call "OnIdle" tasks when py_eval FBs execution queue is empty.
This is usefull to execute slow operations that can be deffered from functions called by py_eval FBs.
User python code add a callable to "OnIdle" list made available in global scope.
// import Nevow.Athena
function init() {
Nevow.Athena.Widget.fromAthenaID(1).callRemote('HMIexec', 'HMIinitialisation');
}
WebInterface.PLC = Nevow.Athena.Widget.subclass('WebInterface.PLC');
WebInterface.PLC.method(
'updateHMI',
function (self, data) {
d = self.callRemote('getPLCElement');
d.addCallback(
function liveElementReceived(le) {
d2 = self.addChildWidgetFromWidgetInfo(le);
d2.addCallback(
function childAdded(widget) {
var node = self.nodeById('content');
node.replaceChild(widget.node, node.getElementsByTagName('div')[0]);
init();
});
});
});
Divmod.Base.addLoadEvent(init);
