Hey All,
I am a little stuck and need some advice/help.
I have a progress bar:
<mx:ProgressBar id="appProgress" mode="manual" width="300" label="{appProgressMsg}" minimum="0" maximum="100"/>
I have two listener functions, one sets the progress, and one sets the appProgressMsg:
public function incProgress(e:TEvent):void {
var p:uint = Math.floor(e.data.number / e.data.total * 100);
trace("Setting Perc." + p);
appProgress.setProgress(p, 100);
}
public function setApplicationProgressStep(e:TEvent):void {
trace("Setting step:" + e.data);
appProgressMsg = e.data;
}
I want to reuse this progress bar alot. And not necessarily for ProgressEvents, but when going through steps.
For instance, I loop over a bunch of database inserts, and want to undate the progress etc.
Here is a sample:
public function updateDatabase(result:Object):void {
var total:int = 0;
var i:int = 0;
var r:SQLResult;
trace("updateDatabase called.");
for each (var table:XML in this.queries.elements("table")) {
var key:String = table.attribute("name");
if (result[key]) {
send(TEvent.UpdateApplicationProgressStep, "Updating " + key);
i = 1;
total = result[key].length;
for each (var row:Object in result[key]) {
//now, we need to see if we already have this record.
send(TEvent.UpdateApplicationProgress, { number:i, total: total } );
r = this.query("select * from " + key + " where server_id = '" + row.id + "'");
if (r.data == null) {
//there is no entry with this id, make one.
this.query(table.insert, row);
} else {
//it exists, so let's update.
this.update(key, row);
}
i++;
}
}
}
}
Everything works fine.
That is, the listener functions are called and I get trace output like:
updateDatabase called.
Setting step:Updating project
Setting Perc 25
Setting Perc 50
Setting Perc 75
Setting Perc 100
The issue is, only the very last percent and step is shown. that is, when it's all done, the progress bar jumps to 100% and shows the last step label.
Does anyone know why this is?
Thanks in advance for any help, Jason
