Ask

Hi, I am trying to use 'ask in one of my scripts: view ask reform ["which layout; " lyts "? "] at the prompt I type: pn1 ** Script Error: view expected view-face argument of type: object ** Where: do-boot ** Near: view ask reform ["which layout; " lyts "? "]

>>view pn1

Hi The result of an Ask is a string. Try ask "What do I get?" and view is expecting a block. I don't think "ASK" is what you want. But you can make it work by doing something like blocks: [ one [button 200x24 water "Button One"] two [size 400x400 across button 200x24 water "Button Two"] ] my-choice: ask "Enter an identifier (one or two): " view layout select blocks to-word my-choice You might want to look at other options that are not so dependent on the user typing exactly what you expect... choice and rotary might be appropriate.

Hi Ammon-- From your example, it's not clear what you need but... View requires a face object or the result of a layout block. You need to defer calling View until you can supply those args. Ask is reserved for collecting user input from the console window. If you want to gather input from the console and *then* use View to produce an interface, try something like (assuming lyts is defined): result: ask reform ["Which layout; " lyts "?"] lay: layout [ h2 gold "You selected:" content: text black 200 "" ] content/text: result show content view lay If the View engine is already engaged, request-text is the preferred method. Try (again, assuming lyts is defined): lay: layout [ h2 gold "Select a layout" content: text black 200 "Click Ask to continue." button "Ask" [ answer: request-text/title reform [ "Which layout " lyts "?" ] clear content/text content/text: answer show content ] ] view lay The Text Fields How-To doc (http://www.rebol.com/how-to/fields.html#sect3.2.) gives some examples of this.

That is enlightening, but does not do what I want. I was just looking for a quick, & dirty solution, I shouldn't ever look for quick & dirty. ;) I got what I need though. Thanks!! Ammon

Hi Ammon, try this solution: x: layout [text "hello"] view do ask "which layout?" ;answer 'x' and the layout should be shown regards, Cyphre

close, but I need text entry. Thanks!! Ammon ----- Original Message ----- From: "CRS - Psy Sel/SPO, COUSSEMENT, Christophe, CPN" <[COUSSEMENT--C--js--mil--be]>

Hi ammon

Nope! Same effect as 'ask: ** Script Error: view expected view-face argument of type: object ** Where: do-boot ** Near: view request-text reform ["which layout; " lyts "? "]

>> view pn1 >> view "pn1"

It is, but the layouts I am trying to view have been DOne. The only place they exist in the raw format is in a complex block. Thus my question, "how to make a string *point* to an object. Thanks!! Ammon

Ammon asked:

> How do I get that value to reference the object!? >> pn1: [text "I'm pn1"]

>> view layout get to-word ask "What layout (pn1)? "

Ammon asked (eventually):

> how to make a string *point* to an object? >> o: make object! [m: 123] >> probe get to-word ask "what object? "

>> probe get to-word ask "what object? "

Ammon, I'm not sure if you oversought my reply or I just don't understand your peoblem but try this: ----- a: layout [text "hello world"] view do request-text/title "which layout?" ----- if you enter 'a' into field layout 'a should be shown... regards, Cyphre

Um... I feel a little sheepish now, I did overlook it on the pretence that it looked like the rest of replies I got. ;( BUT it turns out that it was about 3 characters different; I just needed 'do in there. Thanks!! Ammon PS In the future I will more fully scrutinize EVERY reply. ;)
