What is the correct way to change the color of an image (icon) in a Label component?

HI,

I created a little method that should change the color of the image, but can't make it happen.

In the Label component I load the image like this:

        Label lbImagenInventario = new Label ();

        FontImage.setMaterialIcon (lbImagenInventario, FontImage.MATERIAL_LOCAL_SHIPPING);

And the method is as follows:

    private void changesInventColor (Double quantity, Label lbIcon, Label lbCantidad) {

        if (quantity <0) {

            lbIcono.setIconUIID ("LabelRojo");

            lbCantidad.setText (round (amount, 2));

            lbCantidad.setUIID ("LabelRojo");

        } else if (amount> 0) {

            lbIcono.setIconUIID ("LabelVerde");

            lbCantidad.setText (round (amount, 2));

            lbCantidad.setUIID ("LabelVerde");

        } else {

            lbIcono.setIconUIID ("LabelGris");

            lbCantidad.setText (round (amount, 2));

            lbCantidad.setUIID ("LabelGris");

        }

    }

In this older API the image is created within FontImage and so the colors are coded there. If you change the UIID you need to invoke setMaterialIcon again.

If you use the newer API of Label.setMaterialIcon() it should work seamlessly.

Hi,

Thanks for the reply.

From what I understood the new api also forces me to reload the icon. Would I have to create the icon with the color I want first and then use the new API?

The new API will automatically recreated the icon if you invoke setUIID.
