Hi Isomorphic,

We have a listGrid with an override on getCellHoverComponent, returning a new ListGrid:

@Override
protected Canvas getCellHoverComponent(Record record, Integer rowNum, Integer colNum) {
	if (hoverComponent == null) {
		hoverComponent = (ListGrid) RPCManager.createScreen("LinksDetailViewer");
	}
	hoverComponent.setHoverAutoDestroy(Boolean.FALSE);
	Criteria linksCriteria = new Criteria();
	linksCriteria.addCriteria(C.OBJECTID, record.getAttributeAsInt(C.OBJECTID));
	linksCriteria.addCriteria(C.LOGIDTO, 0);
	DSRequest requestProperties = new DSRequest(DSOperationType.FETCH);
	requestProperties.setShowPrompt(Boolean.FALSE);
	hoverComponent.fetchData(linksCriteria, new DSCallback() {
		
		@Override
		public void execute(DSResponse dsResponse, Object data, DSRequest dsRequest) {
			;
		}
	}, requestProperties);
	return hoverComponent;
}

LinksDetailViewer is:

<?xml version="1.0" encoding="UTF-8"?>
<isomorphicXML xmlns:fmt="WEB-INF/">
	<fmt:bundle basename="com.em.teco.server.Messages" />
	<ListGrid ID="linksListGrid" dataSource="sprlinks" width="250" height="250">
		<hoverMoveWithMouse>true</hoverMoveWithMouse>
		<keepInParentRect>true</keepInParentRect>
		<fetchOperation>fetchAllowedLinksByUsergroups</fetchOperation>
		<overflow>scroll</overflow>
		<autoFitData>vertical</autoFitData>
		<emptyMessage>
			<fmt:message key='pm.links.noinfo' />
		</emptyMessage>
		<loadingMessage>
			<fmt:message key='pm.links.gettinginfo' />
		</loadingMessage>
		<loadingDataMessage>
			<fmt:message key='pm.links.gettinginfo' />
		</loadingDataMessage>
		<showHeader>false</showHeader>
		<fields>
			<ListGridField name="linkCaption" />
			<ListGridField name="linkValue" />
		</fields>
	</ListGrid>
</isomorphicXML>

As can be seen in the attached image, sometimes the amount of records returned with the cellHoverComponent fetch, creates a listgrid that overflows from the browser window.

Is there a way to fix this keeping the getCellHoverComponent override point?

Thanks

If you look at the docs for autoFitData, you can see that related properties autoFitMaxRecords or autoFitMaxHeight can be used to limit auto-fitting to a reasonable maximum.

Hi,

Thanks, this fixed the overflow issue, however it now shows a useless scrollbar as I cannot focus on the hover element before it hides or gets destroyed.

Is there a way to allow the user to have focus on the hover element?

[Isomorphic]

The whole point of a hover is that it's a temporary element that disappears automatically.

If you want an element you can interact with, give the user somewhere to click, and open the same interface in a Window.

@all,

if you find this thread via search, this coming feature of v13.0 might be interesting as well.
