Opening views without closing existing views???

[1/11] from: yvan_iigs:gmx at: 12-May-2006 18:10

Hello, I have a new problem with views. Please take a look at the following code: view layout [ text "Titel" FTitel: field button "OK" [if/else [empty? FTitel/text] [ view layout [ text "Enter Title" button "OK" [unview/all] ] ] [unview/all] ] What I want to do is: 1. If something is entered in the Field and I click "OK" the view is closed. 2. If nothing is entered in the view and I click "OK" then -> a new view is opened with the text "Enter Title" -> without closing the old view <- -> when I click "OK" in the new view, the new view is closed and -> I'm still left with the old view <- 1. Works 2. doesn't work, as soon as I click OK the old view is closed and a new view appears. How can I keep the old view? Cheers Yvan

Try this: view1: view layout [ text "Titel" FTitel: field button "OK" [if/else [empty? FTitel/text] [ view2: view/new layout [ text "Enter Title" button "OK" [unview view2] ] ] [unview/all] ] ] Notes: 1. I've given the views names so you can unview specific ones 2. note the view/NEW on the inner view Incidentally: if/else works, but is definitely deprecated in REBOL. Consider using either instead.

Hi Yvan, Also, the condition argument of the if/else (either) should not be enclosed in a block: view layout [ text "Title" FTitle: field button "OK" [ either (FTitle/text = "") [ view/new layout [ text "Enter Title" button "OK" [unview] ] ][ unview/all ] ] ] Quoting Yvan <yvan_iigs-gmx.net>:

Oops - my mail client doesn't handle tabs well: view layout [ text "Title" FTitle: field button "OK" [ either (FTitle/text = "") [ view/new layout=09[ text "Enter Title" button "OK" [unview] ] ][ unview/all ] ] ] Quoting Yvan <yvan_iigs-gmx.net>:

Hi Yvan, In the script below, please remove the "3D" from the "=3d", and the and the script will operate correctly :) Can anyone recommend a webmail program that will handle those characters better for this mailing list? Thanks! - Nick Quoting Nick Antonaccio <nick-guitarz.org>:

Hi Yvan, You should try the /new refinement : view layout[ text "Titel" FTitel: field button "OK" [either empty? FTitel/text [ view/new newlay: layout [ text "Enter Title" button "OK" [unview newlay focus Ftitel] ] ] [unview/all] ]] But you can also use 'flash like this : view firstlay: layout[ text "Titel" FTitel: field button #"^M""OK" [either empty? FTitel/text [ fl: flash "Enter Title" wait 0.5 unview/only fl focus FTitel ] [unview firstlay] ]] Notice the #"^M" that lets you action the button by pressing "Enter" Hope this will help you. Best regards Ronald

That should be unview/ONLY :

> view layout[ > text "Titel" FTitel: field

<<quoted lines omitted: 4>>

> text "Enter Title" > button "OK" [unview newlay focus Ftitel] ; <---- bad

button "OK" [unview/only newlay focus Ftitel] ; <--- good

> ] > ] > [unview/all] > ]]

Unview by itself will close just the last opened window, which only works until you open a second window. But, to be honest, this approach to field validation seems to be not a good one, if I understand what you're trying to do. Why open a second window asking for the same information? That's just moving the problem to a second window. How about something like this ? view center-face layout [ text "Titel" FTitel: field button "OK" [ either empty? FTitel/text [ FTitel/edge: make FTitel/edge [color: red] focus FTitel ; (also does a SHOW) ][ unview ] ] ] Anton.

Hello Nick, thanks, and by the way I'm using YAM as mailer and it doesn't havve this problem. All you need is a computer able to running MorphOS or AmigaOS to use YAM. On 12.05.2006, you wrote:
