Control of Text Fields

[kray]

Great stack, Roger! I know I'm kind of late to the party, but just FYI you can also use the type command for entering the numbers (an oldie, but a goodie):

Code: Select all

-- Modifying your behavior script
on mouseUp
  type (the label of me)
end mouseUp

Also, for the "Del" button, I think this simple script would work:

Code: Select all

on mouseUp
  delete char (word 4 of the selectedChunk) of the focusedObject
end mouseUp

(and if you ever needed a "forward delete", you could just change it to "word 2 of the selectedChunk")

Just my 2 cents,


Ken

Thank you for these tips, Ken. Is there am advantage to using the type command over put?

Oddly enouugh, TYPE does not seem to be in the dictionary.

For the sake of argument this script locks up Livecode:

Code: Select all

on mouseUp
   put fld "f3" into GUFF
   put GUFF into fld "f1"
   type GUFF into fld "f2"
end mouseUp

Oddly enouugh, TYPE does not seem to be in the dictionary...

Is that so?

NO, it is NOT so . . .

Allow me to blame that on the fact I have only had my first cup of coffee this morning.

The spelling of "enouugh" should be a dead give away.

AND, why, forbye, does this:

Code: Select all

on mouseUp
   put fld "f3" into GUFF
   put GUFF into fld "f1"
   type GUFF into fld "f2"
end mouseUp

NOT result in the TEXT in GUFF being typed into fld "f2"?

I'm aye forfochen.

Disnae seem to like this either:

From the dictionary:

The type command does not automatically place an insertion point in a
field, so if you want to simulate typing into a field, you must first
use the select command to place the insertion point:

select after field "Data"
type "Hello"

Try this.

Kind regards

OK, then you need to read the whole thingie!
This is how to do it, as mentioned in the dictionary:

Code: Select all

on mouseUp
   put fld "f3" into GUFF
   put GUFF into fld "f1"
   
   ## We cannot TYPE diretly INTO, thus:
   focus on fld "f2"
   ## or to specify an insertion point if there is already text in the target field:
   ## select AFTER fld "f2"
   
   ## NOW:
   type GUFF
end mouseUp

I did mention the lack of a second cup of coffee.

No.

Is this because:

1. My text in my original variable is far too large?

2. LC does not like to TYPE from a variable?

-
Apparently #1
-
BUT . . . 'No' . . . after that the thing mysteriously works.

The "advantage" of TYPE s that the text takes up to 10 times as long to end up in the target field, BUT you
can have the pleasure of watching it appear letter-by-letter.

BUT "threw a bluey at the end":

Somewhat underwhelmed by TYPE.

Thank you for these tips, Ken. Is there am advantage to using the type command over put?

The put command involves no messages, the text goes directly into the field. The type command simulates user interaction and sends all the normal messages - keyDown, keyUp, etc. So if you have handlers that monitor user typing, they will trigger normally when the type command executes.

Set the typingRate to 0. The default is 100ms.

[richmond62]

Ouch, trust Jacque to "pip me at the post": what can I say, except,

Lots of love, Richmond.

Between Jacque and Klaus I am doubly humbled.

Ken,
you suggested a simpler version for the Del button, namely

[code]
on mouseUp
delete char (word 4 of the selectedChunk) of the focusedObject
end mouseUp
[/code]
but this doesn't work correctly in the case of an active text selection; the desired (correct) effect in that case is to delete the selected text, while this simple suggestion removes only the last character.

A simple fix is to do
[code]
on mouseup
type " " -- remove existing selection if there is one, then add a space
delete char (word 4 of the selectedChunk) of the focusedObject -- remove that space
end mouseUp
[/code]

Sorry - can't figure out how to get code inserted properly !?
