button_iedit - dosen't work

[Xarxus]

I have a problem with button_iedit. Basically what happens to me is that it does not update (disappears or appears) when I lock the window.
If the window is locked when I open it, the button is not there, if it is not locked the button appears, but it does not change state when the lock changes with the window open.

I have compared my code with other codes I have found and it does not seem different to me. But it does not work. Also I don't see the button_idelete appear and disappear.
I've a doubt. Each code I see has a call like this --> element_list.update(bReadOnly);
But no update is present in element_list; should I implement it? And why other codes do not implement it?

[damned]

it should be called (precisely) listname_iedit

[Moon Wizard]

When in doubt, you can review the templates/scripts being run to create those objects and see exactly what they are doing. All the templates boil down to very simple window controls at their base level (number, string, list, etc.)

As damned mentioned, in order for the button_iedit to link up to the list in the way you expect, it needs to be named exactly "<ListControlName>_iedit".
In your example code, it would need to be named "element_list_iedit", instead of "element_iedit".

What betrayed me is that I found an example (which strangely works, at this point I have to study it better to understand why) in which the name does not match. Thanks a lot to both of you.
