updating a drop list

 [1/6] from: fergus4::bellatlantic::net at: 20-Dec-2005 14:15


I'm want to be able to update the data in a drop list on the fly but I'm having trouble. Basically my code looks like this: Names: ["Bob" "Jack" "Sue"] name_list: name_list display-face: layout [ txts "names:" nam: choi data name_list ] If I change the name_list block by adding a name: name_list: [] names: ["Bob" "Jack" "Sue" "Mary"] name_list: names and refresh the face: show display_face It does not update. I've played around with the "Copy" and I've gotten the list to append to it's self so my list is double in size but just repeats but any added elements are not present. I know the face is being refreshed so my problem is were "name_list" does not seem to be coping the new block.

Try this -- note the magic step is to update nam/texts Names: ["Bob" "Jack" "Sue"] name_list: copy names display-face: layout [ label "names:" nam: choice data name_list button "update" [ name_list: copy ["Bob" "Jack" "Sue" "Mary"] nam/texts: copy name_list show nam ] ] view display-face Sunanda

Got it to work Thanks. I knew to update a field or area etc you use the /text modifier but I did not know about /texts with an "s". -Alan

It's a mess. Some fields you update /text, some you update /texts. And the rules changed between versions. And there's /data too just to add to the confusion. With a bit of luck, the logic is stable now. Sunanda.
