InfoSymbol and TextSymbol

[GregoryBoratyn]

I was wondering if the TextSymbol object can somehow be used with the InfoSymbol object.
This would allow me to have text I can rotate, change color, font size etc. inside the "bubble".
I tried a few options but the text doesn't show up.
I had an InforSymbolRenderer that looks like this:

<Declaration>
    <esri:TextSymbol id="textSymbol" />
</Declaration>

Plus some ActionScript code that initializes text, something like this:
var txtFormat:TextFormat = new TextFormat(textFont.selectedItem.font, numTextSize.value, cpText.selectedColor, bold.selected, italic.selected, underline.selected);
textSymbol.textFormat = txtFormat;
textSymbol.angle = numTextRotation.value;
graphic.symbol = textSymbol; // graphic obj takes geometry as a parameter 

In any case the bubble shows up with the "arrowhead" only, no text.
Any suggestions?
Is this even possible?
Thanks

text parameter

The text string to display.

or textAttribute property

The string representing the attribute of the graphic that should populate the "text" content.

or textFunction property

The text function allows for the text of the text symbol to be dynamically picked - for example based on attributes or position of the graphic.

Sorry, but I did not found any part of code, what initialize text in your sample 😞 - only format and angle

Plus some ActionScript code that initializes text, something like this:
var txtFormat:TextFormat = new TextFormat(textFont.selectedItem.font, numTextSize.value, cpText.selectedColor, bold.selected, italic.selected, underline.selected);
textSymbol.textFormat = txtFormat;
textSymbol.angle = numTextRotation.value;
graphic.symbol = textSymbol; // graphic obj takes geometry as a parameter

Here is more complete version, with a text that TextSymbol constructor takes as an argument.

var textSymbol:TextSymbol = new TextSymbol(txtLabel.text);
var txtFormat:TextFormat = new TextFormat(textFont.selectedItem.font, numTextSize.value, cpText.selectedColor, bold.selected, italic.selected, underline.selected);
textSymbol.textFormat = txtFormat;
textSymbol.angle = numTextRotation.value;
graphic.symbol = textSymbol;


If I do this:

var mySymbol:InfoSymbol = new InfoSymbol();
mySymbol.infoRenderer = new ClassFactory(TextBubbleRenderer);
graphic.symbol = mySymbol;

The TextBubbleRenderer has code I'm showing in my first post...
Here it is again:
<Declaraions>
     <esri:TextSymbol id="textSymbol" />
</Declarations>

The code above that initializes the TextSymbol and TextFormat with all the values is now done in renderer inside the method that gets executed on creationComplete.

As you can see this will compile and work without exceptions, but the Text passed in won't show up in the bubble generated by the InfoSymbol object. I just don't know if I can actually married the InfoSymbol with TextSymbol so that text is displayed in InfoSymbol "bubble".
Can this be done?
Thanks

I still do not understand your plan to put a symbol to other symbol info container...

As I understand, each Symbol (Picture, Text, Composite ...) is tied to the Map and can not exist without it. During symbol initialization, graphic geometry is converted to screen coordinates and the convertion result is the place where symbol must be shown in FLEX application -> in your case TextSymbol has no own Graphic -> has no own Geometry -> as a result can not be shown.
Maybe I'm wrong, but to me it all seems so.

In API reference for com.esri.ags.symbols.InfoSymbol a lot of links to samples.
Based on samples: simple app - add graphic to map with one text attribute ("myTitle"). This attribute is shown in InfoSymbol's container as Label.

and info renderer 'MyInfoSymbolRenderer.mxml' for InfoSymbol:

Good luck.
