VizFrame wait for data to load - renderComplete too soon

former_member125327 — Wed, 30 Nov 2016 10:46:21 GMT

Hey experts

I was wondering if there was any way you can wait for the vizframe to be on the screen. I used the following methods onAfterRendering en renderComplete. They both get called too soon. Usually the vizframe takes 3-5 seconds to load. But I can't use any form of timers. Anyone have any idea what I can use?

kind regards,

Matthijs

This is the method I used, if anyone knows any better way to check, please 
tell me
		waitVizRender: function(oVizFrame) {
			var bRendering = true;
			oVizFrame.addEventDelegate({
				onBeforeRendering: function() {
					if (bRendering === true) {
						sap.ui.core.BusyIndicator.show(0);
					}
				}
			}, oVizFrame);


			oVizFrame.addEventDelegate({
				onAfterRendering: function() {
					oVizFrame.getModel().attachRequestCompleted(function() {
						sap.ui.core.BusyIndicator.hide();
						bRendering = false;
					});
				}
			}, oVizFrame);
		}

Hi Matthijs,

please try this:

oVizFrame3.getModel().attachRequestSent(function() { sap.ui.core.BusyIndicator.show(0); }); oVizFrame3.getModel().attachRequestCompleted(function() { sap.ui.core.BusyIndicator.hide(); });

This works too and is much shorter.

Thank you for answering.
