Hello!
I have a button which enable only on some screens. But when I click on it via poco it is clicking as if it exists always. I tried to use exists() method, but it always returns true.
In my script I see that button enable programmatically
gui.set_enabled(back_icon_node, true)
How to validate this condition in test?
It was a long time since I used the interface, but if I recall correctly, the gui nodes should have properties.
Looking at the code it seems the āenabledā property was left out.
As a workaround, you should be able to call into Lua from your python script and check if the node in question is enabled.
Example 1 which runs in the context of the server. (go or gui)
Example 2 (same context as above)
Can this be fixed in the extension or do we need to add something to our C SDK?
The fix should be in the engine, as itās the one providing the properties.

Thanks for the answer, Mathias. I tried to run this:
cbk = poco.agent.rpc.call("Execute", "gui.is_enabled('back_icon_node')")
cbk.wait()
print("Execute: result: '%s'" % cbk.result)
But result is None.

Ok, strange.
And you are running the poco server in the game form inside the gui script?
Sorry, I missed this moment. Itās needed to add additional poco server for gui script? I already have it in main script.
As mentioned, the call you make is made within the context of the server (in game).
So, if your server is started in your main.script (go), you cannot use āgui.*ā functions.
And vice versa.
Itās seems to me itās inconvenient. Itās possible to start server in multiple scripts?
I donāt know. I guess you can try, as long as you set different ports for each server?

Ok. Perhaps not enough information I provided. I will try to collect all about my case.
In app I have gui script with such code:
local function update_top_bar(self, animate)
...
local back_icon_node = gui.get_node("back_icon")
...
gui.set_enabled(back_icon_node, false)
I have added poco-server in init and update functions of gui script.
function update(self, dt)
poco:server_loop()
poco:set_view_proj(get_view_proj())
poco:set_gui_view_proj(get_gui_view_proj())
end
function init(self)
...
poco:init_server(15004)
Also added functions to get get projections:
local camera = require "render.camera"
local function get_view_proj()
local view = camera.get_view(nil)
local proj = camera.get_projection(nil)
return proj * view
end
local function get_gui_view_proj()
local x, y = camera.get_window_size()
local mat = vmath.matrix4_orthographic(0, x, 0, y, -1, 1)
return mat
end
Then I maked sure that everything is ok by test of clicking on any button. Now I try to get state of button āback_iconā I have tried this:
cbk = poco.agent.rpc.call("Execute", "gui.is_enabled('back_icon_node')")
cbk.wait()
print("Execute: result: '%s'" % cbk.result)
and
cbk = poco.agent.rpc.call("Execute", "gui.is_enabled('back_icon')")
cbk.wait()
print("Execute: result: '%s'" % cbk.result)
Python test script (now I use windows app)
import sys
import unittest
from poco.drivers.std import StdPoco
from poco.utils.device import VirtualDevice
import util
options, args = util.parse_arguments(sys.argv)
options.address = "127.0.0.1"
device = VirtualDevice(options.address)
poco = StdPoco(addr=(options.address, options.port), device=device, use_airtest_input=False)
cbk = poco.agent.rpc.call("Execute", "gui.get_position(back_icon_node)")
cbk.wait()
print("Execute: result: '%s'" % cbk.result)
But result is always None. Would be glad any additional information.
I havenāt tried this myself, but maybe you actually need to return something?
poco.agent.rpc.call("Execute", "return gui.is_enabled('back_icon')")
Edit: Yes, looks like thatās the way: https://github.com/defold/extension-poco/blob/master/poco/lua/defold-poco.lua#L89-L96

Thanks for advise. I tried this but it has no effect.
Itās because the code isnāt valid gui.* code.
The gui.is_enabled(node) takes a node, not an id.
cbk = poco.agent.rpc.call("Execute", "return gui.is_enabled(gui.get_node('back_icon'))")
Iāve also updated the master branch of the extension with another example.
Select the gui_server/main.collection as the main collection, and start the game.
Then run the python script examples/example_execute_gui.py and it should print out the enabled state of the two gui boxes:
users/mawe/extension-poco $ python examples/example_execute_gui.py [master] 11:14:35
[rpc]connected
Execute: result: 'False'
Execute: result: 'True'
Done
Yes! It works!
Now I add clicking on button āMerge Mastersā which enables āback_iconā button
poco(text='Merge Masters').click()
cbk = poco.agent.rpc.call("Execute", "return gui.is_enabled(gui.get_node('back_icon'))")
cbk.wait()
print("Execute: result: '%s'" % cbk.result)
But in this case I get result āNoneā.

You might need to wait for the click to be done?
I added time.sleep(5) before rpc call. Also I leaved only sleep without clicking. In this case result of rpc call is always āNoneā
time.sleep(5)
cbk = poco.agent.rpc.call("Execute", "return gui.is_enabled(gui.get_node('back_icon'))")
cbk.wait()
print("Execute: result: '%s'" % cbk.result)
Did you update the extension-poco to the latest version? (the master.zip)
I tried to add better error handling there (not sure if it helped though)
Also, you can try the example function I added in the main.gui_script:
poco:set_dispatch_fn("GuiIsEnabled", function(id)
print("INSIDE GuiIsEnabled FUNCTION!",id)
return gui.is_enabled(gui.get_node(id))
end)
Called from python:
cbk = poco.agent.rpc.call("GuiIsEnabled", "back_icon")
cbk.wait()
print("Execute: result: '%s'" % cbk.result)
For further info, I recommend you debug the defold-poco.lua file
Sorry missed this. Now updated. In last case with sleep I got error:
Execute: result: 'Failed to run 'return gui.is_enabled(gui.get_node('back_icon'))'. Error: [string "return gui.is_enabled(gui.get_node('back_icon'))"]:1: You can only access gui.* functions and values from a gui script instance (.gui_script file)'
This is what I meant earlier. "gui." functions can only be used in the context of gui scripts (and vice versa for go. functions)
It seems youāre sending the call to a .script ?
You previously had a server running on a separate port in the .gui_script, where did that go?
