We have a ticket similar to this one related to detecting when the mobile apps are minimized/restored (DEF-1146) but we didn’t have one for desktop apps that covered both the case of minimize/restore and active/inactive so I went ahead and created a ticket for it: DEF-1994

This issue was fixed with DEF-1146 so I’m marking this as solved (http://www.defold.com/ref/window/)

Has anyone confirmed that this is working? In 1.2.89, I get an undefined symbol when trying to call window on an iOS device :frowning:

#5

I tried it again now, and it works for me. What part actually goes wrong? Does the window module not exist? what function are you trying to call?

#6

It crashes with an undefined symbol of “window” with the line:

window.set_listener(window_listener)

Also, I don’t get any autocompletion from window. in the Defold editor, as in the case of gui, go or push for example.

#7

Is window_listener defined?

Great. And where is that function defined in the source file? Before or after you reference it?

#10

Can you test a blank project with just the single script on your iOS device?

local function window_listener(self, event, data) -- edited to fix mistake
     if event == window.WINDOW_EVENT_FOCUS_GAINED then
         print("focus has been gained")
     end
     if event == window.WINDOW_EVENT_RESIZED then -- edited to add example
         print(data.height, data.width)
     end
end

function init(self) -- edited to move after
    window.set_listener(window_listener)
end

@Mathias_Westerdahl helped me with the issue and it boiled down to our build server grabbing an old version which didn’t include window.
