Hi Pamela,
Thank you for the ProgressBarControl!
I'm setting it up to track the progress of markers as they are
rendered on the map.
Unfortunately, I've got the progressbar displaying only after all of
the markers are rendered. So, there is no progressbar, the markers are
drawn, and then the progressbar displays showing that everything was
rendered.
In the example enclosed in the folder, he uses the setTimeout method
in order to get the browser to update the screen and show changes in
the progressbar. I tried it, but I couldn't figure it out. I noticed
that the example uses GMarkers. Is there an all-Flex marker example?
In the documentation, it mentions the remove method, which I didn't
find with code hinting. Flex wouldn't let me use remove.
Please find below my code. The code places markers and the progressbar
shows after all of the markers are rendered. What do I need to add in
order to get the progressbar to show "progress"?
public function pointsBuilder():void {
var progressMX:ProgressbarMapControlMX = new ProgressbarMapControlMX;
progressMX.x = 200;
progressMX.y = 200;
progressMX.width = 150;
progressMX.height = 100;
addChild(progressMX);
markerBoss = new MarkerManager(map, {maxZoom: 16});
var myArrayLength:uint = myData.length;
progressMX.start(myArrayLength);
var i:int;
for (i=0; i < myArrayLength; i++) {
progressMX.updateLoader(1);
myMarkers = new Marker(new LatLng(myData[i].latitude, myData
[i].longitude),
new MarkerOptions({
strokeStyle: new StrokeStyle({color: 0x000000}),
fillStyle: new FillStyle({color: 0x223344, alpha: 0.8}),
radius: 12,
hasShadow: true
})
);
markerBoss.addMarker(myMarkers, 16, 16);
}
markerBoss.refresh();
}
Also, what's the difference between ProgressbarMapControl.as and
ProgressbarMapControlMX.as?
If anyone has any suggestions, please let me know.
Thank you.
