Call class method with GUI g-label
Posted: 19 Apr 2021, 10:43
Hello scripters!
I'm working on a new little script which involves creating a number of GUIs inside a class. Running through some concepts and I seem to be unable to reference the class methods with a GUI g-label.
As expected - not using classes at all - this works:
Correctly shows the GUI and triggers the msgbox when the text is clicked.
I found that this also works:
With hello() defined as a function outside the class, it is recognised as a valid label and triggered when the text is clicked.
However, with hello() defined as a class method, I was not able to find a way to reference it with the g-label:
This results in an error at runtime, "target label does not exist, specifically ghello". I tried creating a reference to the hello() method by writing createGUI() like this:
Which returns no errors at runtime but the messagebox does not appear when clicked; or like this:
Which has the same behaviour.
Using func("this.hello") instead results in runtime error "Target label does not exist, specifically g0" which I think is AHK's way of telling me that func("this.hello") returned an empty function object.
My workaround at the moment is to build my GUIs inside class methods and put the g-label routines in the same module outside of the class. This is functional but if there's a way to use the g-label routines as class methods I would prefer to do that instead.
If there's an existing script or module that implements this that would be great - I'm sure I could figure it out just looking at an example of what I'm trying to do.
Thanks!
