Understanding LIST better

 [1/3] from: DNess::comcast::net at: 28-Jul-2003 14:13

I have some code that uses `list[...]data[...]' to display some data. Very occasionally I would like to `color' one of the data items in some way (note: I mean color a single data item, not a column of data), and am wondering if this is possible. The program that generates the data[...] values _is_ under my control so I can cause it to be marked up in any way that is necessary. An example might be to produce 1.1 2.2 3.3 4.4 -5.5 6.6 7.7 8.8 9.9 where the -5.5 is colored red and all the rest are black... If there is some place that I can read more about layout list I'd appreciate a pointer...

Hello David, my-list: list gray list-size list-layout-blk data list-data supply [ ; count is the row number ; index is the face number row: pick head l-block count but/text: all [row pick row 1] fld/text: all [row pick row 2] ] (index is also like the column, assuming your list layout goes across.) The code above is from this example: You can see that the text is not the only facet you can change. You could also do: value: all [row pick row 1] but/font/color: any [all [negative? value red] black] and/or set the background color with: but/color: all [negative? value maroon] ; (none is transparent) Anton.

Your example is highly instructive. It will take me a while to study it, and it will probably provoke some further questions, but in the meantime thank you for taking the trouble to point out this very useful example. 7/28/2003 8:26:22 PM, Anton <[antonr--iinet--net--au]> wrote:
