Calendar (dateedit) feature request

[David Z.]

I'm not sure if this a GDC or BDL topic. If the user is in a dateedit field, it would be nice if the user could hit the numeric keypad plus (+) to move forward one day and the minus (-) to go back one day. Also, Ctrl +/- for one month, and Alt +/- for one year.

Thanks,
David

I will second that request. :)
I had asked previously about the (+) and (-) for day changes and I like your ideas for month and year movement on top of those.

Hi,

Indeed the request about (+) and (-) was already asked by Tim and was filed as bz.#16217 (DateEdit hot keys and helpers). I completed the description with propositions made by David. Thank you for the suggestions!

I implemented something similar in my previous job based on functionality I saw in an application (non-4GL) I was exposed to before that.

It was to help keyboard users enter dates.

Basically if you were in a  dateedit field you could a small (1 or 2 characters), press a function key, and have that interpreted into a date.

The expressions were something simple like ...

0 = today
1,2,...,31 = that day of the current month and year
+1 = tomorrow
+2,+3,... = that many days after today
-1 = yesterday
-2,-3,... = that many days before today

... and rarely used complex stuff like ...

+1[wmy] = add that many weeks, months, years to todays date
-1[wmy] = subtract that many weeks, months, years to todays date

<[wmy] = first day of the current week, month, year
>[wmy] = last day of the current week, month, year

and then it hooked into the accounts system so that

<[pqhf] = first day of the current period, quarter, half-year, financial year
>[pqhf] = last day of the current period, quarter, half-year, financial year

as well as other functionality for expressions like 20th following month, as well as only taking working days into consideration

... anyway to implement this in 4GL it was something like

Code (genero) Select Expand

ON ACTION datewizard
  CALL FGL_DIALOG_SETBUFFER(datewizard(FGL_DIALOG_GETBUFFER()))

... and

Code (genero) Select Expand

FUNCTION datewizard(s)
DEFINE s STRING
  CASE
     WHEN s = "0" LET s = TODAY
...
     OTHERWISE
        -- leave s unchanged if unable to process
  RETURN s
END FUNCTION

... and note that if you are using UNBUFFERED you have to set the validate attribute of the action to "no" e.g.

Code (xml) Select Expand

<ActionDefault name="datewizard"      acceleratorName="F8" defaultView="auto"     validate="no" />
... from memory I added as a global action so I didn't have to explicitly code into every single dialog
