there is on eissue concerning the editingmode.
Maybe a kind of bug.
In my efforts to incorporate a keyboardcontrolling to a ListIconGadget
a stumbled on this.
Editing with DEL-KEY does not update the TEXT in the callback at once
like other editinputs do.
This is a little bit annoying because i have to manage the editstate when exiting
the editmode with up or down arrow to switch to the next field.
I need the correct edited value to write it immediately into a database when changed
(left and right-arrow are not considered)
Here some code to test. Arrowing up and down in editmode does work.
The recognition of changed values (when up or down) depends on the last editinput.
DEL is not recognized.
Leaving the EditMode with ENTER is ok in this case.
Code:
;
; List
EnableExplicit
Enumeration ;window
#win
EndEnumeration
Enumeration ;gadgets
#b_Get
#b_Quit
#Li
EndEnumeration
Enumeration ;shortcuts menu
#sk_down
#sk_up
EndEnumeration
