Newbie Q: Modifying Text-List

 [1/4] from: blemeri:noos at: 20-Oct-2002 19:11


Hi, I try to add items to a list bbl and the associated text-list: bbl: [ "a" "b" "c" ] view layout [ button "Add" bold [ repend bbl copy t1/text bbl: sort unique bbl show cl ] t1: area 340x280 cl: text-list data bbl ] the text list is not updated after the second added item. this script works fine without "bbl: sort unique bbl". Anyone could give me a hint ? (I found no response in Brett Vid/view notes) Thx, Bruno.

Hi Bruno, << the text list is not updated after the second added item. this script works fine without "bbl: sort unique bbl". Anyone could give me a hint ? >> Your text list is referencing the original *value* of bbl. When you use UNIQUE, it generates a new *different* value which, while still referenced by the word bbl, is not referenced by text-list/lines (which is still looking that the original value). If you reset the reference for the text-list after changing the data, all is well. bbl: [ "a" "b" "c" ] view layout [ button "Add" bold [ repend bbl copy t1/text cl/lines: bbl: sort unique bbl show cl ] t1: area 340x280 cl: text-list data bbl ] HTH! --Gregg

Hi, Bruno, unique returns a new block that you have reassigned to bbl. cl/lines needs to be repointed to this new block. (I don't know why it works the first time only, though.) Hopefully this code works: bbl: [ "a" "b" "c" ] view layout [ button "Add" bold [ repend bbl copy t1/text bbl: sort unique bbl cl/lines: :bbl show cl ] t1: area 340x280 cl: text-list data bbl ] (Note well: this will change with the next /View/VID, where the /data path will contain the block used by the text-list.)

Thank you Gregg and G. for this "cl/lines" and explanations. Regards, Bruno.
