Color Palette on graphics

IbrahimHussein — Mon, 15 Sep 2014 16:14:43 GMT

Hello,

If you look at the example above, when you click a text field a color Palette comes up; is there an easy way to do this for a graphic (eclipse, triangle...) as well?

edit - Answer -

var myPalette = new ColorPalette({

palette: "7x10",

onChange: function(val){

if(grfx.geometry.type==="point")

{return;}

var result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(val);

var r = parseInt(result[1], 16)

var g = parseInt(result[2], 16)

var b = parseInt(result[3], 16)

var symbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID,

new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,

new Color([0,0,0]), 2),new Color([r,g,b,0.75]));

grfx.setSymbol(symbol);

}

}, "colorPal").startup();

On graphic click, I set the symbol to the color palette.

You have the reference to ColorPalette so the textbox probably uses the dojo widget. You could hide a <div> with the colorpalette widget, then on an event (edit a marker) it becomes visible and the color chosen updates the graphic.

Thanks for the reply. I actually started to do that, that's why there's a reference to colorPalette. If the reference is removed, it still shows up for the Text Box.

Hey Ibrahim,

I have created this Javascript API - Advanced Draw widget

Maybe that can help you
