VID: layout problem

 [1/5] from: robert:muench:robertmuench at: 17-Oct-2002 17:38


Hi, I need some VID guru help for the following problem/questions: 1. As I understand VID field-layout: [ lab "surname" surname: fld return lab "lastname" lastname: fld return ... ] Executing <layout field-layout> anywhere in my script will create two global words 'surname and 'lastname referencing field objects. Is this right? 2. My problem is that I dynamically create a block like field-layout in a function and execute the layout command in this function too. I'm using code like repend field-layout [to-set-path field 'fld 'return] To get the variables into the block. I'm using to-set-path and not to-set-word because field can be a path too. That's the result I get: ** Script Error: surname has no value ** Where: do-facets ** Near: surname: Hmm... Of course has 'surname no value. I expect the layout function to assign a value to it and add it to the global context. If I change to-set-path to-set-word everything works fine. Is there anything I'm missing? Robert

Hi Robert, << I'm using to-set-path and not to-set-word because field can be a path too. ...If I change to-set-path to-set-word everything works fine. >> If you use a string value (e.g. "a/b/c") TO SET-WORD! should work on it, but it does fail on true path values. Will that work for you with the way you're generating the code? If you have a path! value already, you could do this: path-to-set-word: func [path] [ to set-word! rejoin [first path "/" next path] ] path-to-set-word 'x/y/z path-to-set-word 'abc/def/ghi --Gregg

Hi Robert, On Thursday, October 17, 2002, 5:38:23 PM, you wrote: RMM> To get the variables into the block. I'm using to-set-path and not RMM> to-set-word because field can be a path too. But if it's only a word I don't think it would work. Also, I think LAYOUT does not support set-paths for setting a face.

Yes, assuming fld is a field style you've created. ie... lo: [ style fld field 40 ; create short field across label "surname" surname: fld return label "lastname" lastname: fld return ] view layout lo

Hmmm. Assuming I've understood what you're trying to do, I'd feel that using compose on the block would be simplier than the above. ie, something like this... s-name: "Bloggs" lo: [ across ] append lo compose [label "surname" surname: field (s-name) return] view layout lo And in fact s-name: could be surname: if you wanted, which would allow you to move it out of the layout. ie... surname: "Bloggs" lo: [ across ] append lo compose [ label "surname" field (surname) [print surname] return ] view layout lo All of which assumes my guess at what you're trying to do is right... -- Carl Read

Hi, I though that too but to-set-path works if you just provide a word! :-). So I don't know why we need to-set-word. I have to say that I didn't checked if to-set-path with a word yields a path! Or a word!.

Ok, I think that might be the problem. Robert
