Has anyone managed to get the hoverComponent to work with a TileGrid? I've made use of the following:
When the method is overridden for a normal Canvas object (such as a DynamicForm, for example), the Hover item appears correctly (and bravo - it looks fantastic).
Overriding the Parent tileGrid does nothing, BUT - this suggests the way forward:
The code I've tried to use is as follows:
Unfortunately this doesn't trigger a DetailViewer hovercomponent. There's a dearth of use cases, and javadoc the isn't enlightening.
Thanks,
Terry
Code:
@Override
public Canvas getHoverComponent() {
Record record = tileGrid.getSelectedRecord();
DetailViewer hoverViewer = new DetailViewer();
hoverViewer.setWidth(200);
hoverViewer.setDataSource(ds);
Criteria criteria = new Criteria();
criteria.addCriteria("itemID", record.getAttribute("itemID"));
hoverViewer.fetchData(criteria);
return hoverViewer;
}
testCanvas.setShowHover(true);
testCanvas.setCanHover(true);
testCanvas.setShowHoverComponents(true);Overriding the Parent tileGrid does nothing, BUT - this suggests the way forward:

Use setTileProperties() to enable the normal Canvas-level properties and event handlers for hovers.

Code:
//TileGrid
final static TileGrid tileGrid = new TileGrid();
//setTileProperties Canvas
final static Canvas tileCanvas = new Canvas(){
//Override the getHoverComponent for the setTilesProperties Canvas
//This is identical to the previous test case
@Override
public Canvas getHoverComponent() {
Record record = tileGrid.getSelectedRecord();
DetailViewer hoverViewer = new DetailViewer();
hoverViewer.setWidth(200);
hoverViewer.setDataSource(ds);
Criteria criteria = new Criteria();
criteria.addCriteria("itemID", record.getAttribute("itemID"));
hoverViewer.fetchData(criteria);
return hoverViewer;
}
};
final static DataSource ds = SwitchXmlDS.getInstance();
private static void setupTileGrid() {
tileCanvas.setShowHover(true);
tileCanvas.setCanHover(true);
tileCanvas.setShowHoverComponents(true);
//set the TileProperty to use tileCanvas settings
tileGrid.setTileProperties(tileCanvas);
}Thanks,
