Code: Select all
SendMessage_(GadgetID(Gadget), #EM_GETMODIFY, #Null, #Null)
And for the next question
Code: Select all
SendMessage_(GadgetID(Gadget), #EM_SETMODIFY, #True, #Null)
or
Code: Select all
SendMessage_(GadgetID(Gadget), #EM_SETMODIFY, #False, #Null)

I'm not sure how to use this (I'm new to using Editorgadgets).
Something like?
Code: Select all
result.l = SendMessage_(GadgetID(Gadget), #EM_GETMODIFY, #Null, #Null)
Do I need to scan for this message? Is it a Windowevent?

>> Is it a Windowevent?
no
Example: User close window, you can test saving required

I see, and it returns -1 (non zero) if changes are made. Otherwise 0.
Thanks.
