Hi, I have the following problem: I'm using a list style to display some data. For the list style you supply a layout block that gets called once the block containing the list style gets layouted:
mygui: layout [ lst: list 200x200 lstlayout supply lstsupply] Than for each row in the list that can be displayed lstsupply is called for all columns. In my situation I need to execute a block of code once before the list get's updated and once the list updated ended. The pattern should be like this: - lstlayout once when calling layout - lstconstructor once the list drawing starts - lstsupply gets called (row * columns) times - lstdestructor once the list drawing ended Something like this: mygui: layout [ lst: list 200x200 lstlayout start lstconstructor supply lstsupply end lstdestructor] Is this possible?
