Dynamic Views possible

 [1/3] from: yvan_iigs::gmx::net at: 2-Dec-2006 14:11


Hello, is there a way to tell a view which fields it should show by passing any kind of parameters? Lets assume I have a video database with the following strings per video: title, producer, release-date, length Now if I want to look at a video record I can do it the following way: view layout [ text title text producer text release-date text length ] But if I just want to see the title I would have to do the following: view layout [ text title] and if I just want to see the title and the producer view layout [ text title text producer ] okay, it's getting boring. I have much more than just 4 different variable per video record and I'm looking to program a function which let's me chose which fields of the video-record should be shown without having to program a special view for each possible combination. Is there a way to to this? Cheers Yvan

Hi Yvan, Try something like this, of course you can do the function as complex as you want but, this is the idea func-lay: func [fld-block /local lay-block][ lay-block: copy [across] foreach [f-name f-data] fld-block [ append lay-block reduce ['txt rejoin [to-string f-name ": "] 'txt to-string f-data 'return] ] lay-block ] view layout func-lay [name1 text1 name2 text2] CÚsar

Hello Cesar, I think I see what you mean. The concept of dynamic views doestn't exist and I more or lesse have to make the layout myself before entering it into the view. Okay, I think I have to modify your func-lay a little bit before it takes me to my goal. Thank you for the hint. Cheers Yvan On 2.12.2006, you wrote:
