Using SetTexture to change the texture of a frame created by another addon?

GwGarrisonButton is a frame created by GW2 UI

The goal with that code is to change gwbutton's texture to another one.

If I get it to work I'll start employing the same to other frames

Lua Code:
  1. UIMod_UpdateInterval = 0.3; -- How often the OnUpdate code will run (in seconds)
  2.  
  3.  
  4. f.TimeSinceLastUpdate = 0
  5.  
  6. f:SetScript("OnUpdate",function(self,elapsed)
  7.         local gwbutton = GwGarrisonButton
  8.         local garrisonType = C_Garrison.GetLandingPageGarrisonType()
  9.         local covenantID = C_Covenants.GetActiveCovenantID()
  10.     self.TimeSinceLastUpdate = self.TimeSinceLastUpdate + elapsed;
  11.  
  12.  
  13.     if (self.TimeSinceLastUpdate > UIMod_UpdateInterval) then
  14.         print("UIMOD OnUpdate");
  15.                 if gwbutton and gwbutton:IsShown() and gwbutton:IsVisible() and (covenantID ~= 0 or garrisonType == 111 or garrisonType == 3) then
  16.                         print("UIMOD OnUpdate: GW2 UI Garrison Button is shown. Editing texture.");
  17.                         gwbutton:SetTexture("Interface/AddOns/UIMod/textures/icon-1")
  18.                 end
  19.  
  20.  
  21.         self.TimeSinceLastUpdate = 0;
  22.         UIMod_UpdateInterval = 30.0;
  23.     end
  24. end)

However this returns me an error. Apparently I can't use SetTexture that way. I tried googling around but only found people talking about changing Blizzard's default textures.

How do I change the texture of a frame created by another addon?

Maybe a XML file could help in this case?

This is the error I'm getting:

Buttons don't have a SetTexture method. You can only call SetTexture on an actual texture. However, buttons do have SetNormalTexture and SetPushedTexture methods for setting their visuals.

Using SetNormalTexture instead of SetTexture worked, thanks!
