AuGeo (Template)

Hi,
I am using AuGeo (Template) provided for AppStudio for ArcGIS Desktop.
I am not changing the source code by Qt Creator, but I will fail to query the feature of feature service when tap the "Refresh Data" button on the map screen.
Looking at the console of AppStudio, the extent of the geometry used for the query is non.
It seems that the extent of the map is not get correctly, where should it be fixed?

Hi,

It seems that visibleRegion of map has not been acquired.
The following Qt bug may be involved.
https://bugreports.qt.io/browse/QTBUG-56071

I was able to work around this problem by modifying the code on the MapPage.qml.

current:

var extent = QtPositioning.shapeToRectangle(map.visibleRegion);

workaround:

var xmin = map.toCoordinate(Qt.point(0, 0)).longitude;
var ymin = map.toCoordinate(Qt.point(map.width, map.height)).latitude;
var xmax = map.toCoordinate(Qt.point(map.width, map.height)).longitude;
var ymax = map.toCoordinate(Qt.point(0, 0)).latitude;
var extent = QtPositioning.rectangle(QtPositioning.coordinate(ymax, xmin), QtPositioning.coordinate(ymin, xmax));
