gtk-entry icon size

[sapomuyverde]

Hi,
I am trying to use the vertex theme in an application under Windows, but I don't know where to modify so that the icon is displayed larger in a gtk-entry, I have only tried with

gtk-icon-sizes = "gtk-button=24,24"
or gtk-icon-sizes = "gtk-entry=24,24"

and this did not work, I attached image of how it looks.

I appreciate any help.

Regards,
Javier
