First try at converting a XOJO program of OBJO and I am trying to subclass a listbox. The documentation doesn’t include listbox as subclass-able. I’m wondering if I’ve missed something.
Hi,
Create a Class and change type “Super:” to ListBox
I placed a listbox on the window and have created a separate listbox class (cListbox). I can’t find a way to set the super on the window from Listbox to cListbox. I tried dropping the subclass listbox on the window but get a runtime exception 'Cannot instantiate abstract class cListbox. There’s a lot to like in Ojbo but I’m struggling to navigate after years of XOJO.
It looks like I had the abstract class checkmark set. Another baby step.
Hi,
try example here: https://limewire.com/d/9Nzm2#yCjUQ1fF7R
Thanks, my mistake was thinking I could add a listbox to the window and change the super. Once I dragged the listbox class to the window (and click off abstract) things started working. I’m enjoying Objo but must admit I’m having trouble getting used to the editor.
